FIELD OF INVENTION -
:
The present invention relates to novel hair rinse conditioning
compositions, which may be clear or opaque, capable of providing
superior dry feel and high luster properties to hair ereated there-
wlth, compri~sing a ternary mixture of polyvinyl pyrrolidone/vinyl ~-
acetate (PVP/VA) copolymer, at least~one hydrophilic cationic -~
quaternary ammonium compound and a water ~soluble nonionic cellulose
,
polymer in an aqueous vehicle. The use of this ternary mixture is
essential in order to obtain the superior dry feel and high luster
hair properties. Also, this mixture is readily and completely
removable from the hair by simply shampooing; and does not cause
an undesirable build-up of conditioner on the hair.

BAC~GROUND AND PRIOR ART
_
Conventional rinse conditioners comprise cationic-fatty alcohol
emulsion systems which tend to oil and grease the hair. The
cationic quaternary compounds may have a hydrophobic group or
groups such as lauryl, cetyl, stearyl or benzyl attached to
the nitrogen atom or may have a less hydrophobic group such as
a polyoxypropylene amido alkyl radical of 3 to 60 propylene oxide
groups attached to the nitrogen atom as shown in U.S 3,155,591.
These hair substantive cationics are used to emulsify oils or fatty
substances such as fat~y alcohols, amides or glycols to enhance
the wet and dry combing properties of the cationic. Unfortunately,
they provide conditioning of an oily or fatty nature that leaves a
dulling effect on the hair.
The prior art also dlscloses other hair conditioning composi-
j tions containing conventional hydrophobic quaternary ammonium com-
pounds containing a higher alkyl or alkenyl group of more than
1 eight carbon atoms,usually 16 - 18 carbon atoms,together with resins
;i such as PVP/VA copolymers in hair setting co=positions. More
specifically, U.S. Patent No. 3~144,391 shows hair s tting compositions
'I containing water insoluble copolymers of vinyl pyrrolidone with vinyl
esters of fatty acids such as a copolymer of vinyl acetate and
vinyl pyrrolidone (40:60 to 85:15) and a minor proportion of a cationic

sur~actant containing a hydrocarbon radical of at least 8
carbon atoms and ethyl alcohol. U.S. Patent No. 3,~94,141,
too, discloses a method of hair condit~oning by applyino
an aqueous setting solution comprising a disulfide co~pound
containing a nitrogen atom, a PVP/VA copolymer and a ~inor
proportion of a quaternary af~fonium compound such as trimethyl
cetyl a~nonium bromide (column 6 lines 15-30). Similarly, U.S.
Patent ~o. 4,348,383 discloses hair setting lacquers or lotions com-
prising dithioether com?ounds for reducing the oily appearance of
the hair in com~ination w1th a cosmetic resin such as PVP/VA
copolymers (column 3 lines 53-54) and quaternary ammonium compounds
(column 4 lines 7 and 52-54) in an aqueous, alcoholic, or hydro- ~-
I alcoholic soIution. However, this group of pa~ents relates primarily
i to hair setting solutions containing the PVP/VA copolymer as the
iff film-forming ap,ent, not to hair rinse conditioners which give the hair
I¦ superior dry feel and high luster properties. ~-
¦ The prior art also discloses water-soluble quaternary ammonium
~ compounds as a skin substantive emollient in cosmetic products, e.g.,
¦ hs1r styling gels~shown in U.S. Patents Nos. 3,766,267 and No. 3,8~5,290
¦ ;which further include a carboxylsted vinyl polymer. On the other
ùand, said water-soluble quaternary ammfonium compounds have been used
as a~conditio~ing agent in hair rinses containing a lubricant such as

a higher fatty alcohol as shown in U.S. Patent No. 3,155,591.
~ut, no PVP/VA copolymer or other ql1aternary compound is disclosed

U.S. Patents Nos. 4,220,168 and 4,374,125 disclose, respectively,
a moisture control hair spray composition containing PVP/VA copolymers
as an optional ingredient and a moisture stabilizing conditioner
containing a quaternary ammonium salt conditioner a~ an optional
ingredient.
However, none of the foregoing patents discloses a hair conditioning
composition having dry feel and high hair luster propertie~ comprising
the ~ernary mixture of a PVP/VA copoIymer, one or more hydrophilic
cationic quaternary ammonium compounds and a water soluble nonionic
cellulose polymer~1n an aqueous medium wherein said qu}ternary compound
is present in the prescribed proportion to the PVP/VA copolymer.

The present invention provides a hair rinse
conditioning composition capable of providing superi.or dry feel
and high luster properties comprising, by weight, a ternary
mixture of 0.5% to 15% of a polyvinylpyrrolidone/vinyl acetate
copolymer; 0.1% to 10% of at least one hydrophilic cationic
quaternary ammonium salt which is free of alkyl or alkenyl
radicals containing at least eight carbon atoms in the molecule,
the weight ratio of said quaternary compound to said copolymer
being in the range of 1:5 to 20:1; and 0.1% to 4% of a water
solub~e nonionic cellulose polymer in 71% to 99.3% of an
aqueous medium, said composition having a pH in the range of
3 to 6. The aqueous medium constitutes about 71% to 99.3%,
preferably 80% to 98.3%, most preferably 90% to 97.7% by weight
of the composition.
More specifically, the present invention relates to
a hair conditioning composition which provides the hair treated
therewith with superior dry feel and high luster properties,
containing as the essential conditioning agents, a ternary
mixture of about 0.5-15% by weigh~ of a PVP/VA copolymer, about
0.1%-10% by weight of at least one cationic quaternary compound - .
with a hydrophilic group attached to the nitrogen atoml and
about 0.1-4% by weight of a water soluble nonionic cellulose
polymer ln 71-99.3% by weight of an aqueous vehicle.
The performance criteria of a good hair conditioning
rinse is: disperses well throughout the hair upon application,
provides good ease of wet combing, i.e., detangles the hair
withou~ damaging it; provides good ease of dry combing with
good hair manageability; and maintains good hair shine without ~ .
an oily feel. Typically, clean hair is shin~ and hair treated
with rinse conditioners is usually dull in appearance.

DETAILED ~ESCRIPTION OF THE INVENTION
It has been found that more desirable rinse conditioners can
be made by using polyvinylpyrrolidone/vinyl acetate (PVP/VA)
copolymers in place of the fatty materials conventionally used.
Such conditioners impart a dry feel, good body and improved shine
properties to the hair. Further, it has been found that superior
dry feel/high hair luster rinse conditioners can be made by employ-
ino such polyvinylpyrrolidone/vinyl acetate copolymers in combina-
tion with a quaternary ammonium compound which has hydrophilic
properties, i.e., a compound which is~wholly or partly soluble in
water and does not contain a hydrophobic alkyl or alkenyl radical
of more than ei8ht carbon ~toms ln the molecule. This impr~ved
rinse conditioner i~parts good wet co=bing, superior hair~luster,
good body and very good dry hair =aoageability to hair treated
therewith. ~It has also been found that the addition of the more
hydrophilic cationic~compound enhances the hair shine~properties of
I ~ PVP/VA copolymer rinse conditioners even when a usual hydrophobic type
cationic compound such as stearyl dimethyl benzyl ammonium chloride
1 or di-hydrogenated tallow dimethyl a = onium chloride is present, too.
Furthermore, the presence of a water soluble nonionic ccllulose
, polymer further enhanc~s the conditioning properties of the~hair rinse-
conditioner. It is believed that the coaction of this ternary mixture

5~
of ingredien~s is responsible for the superior and unexpected con-
ditioning effects, including the substantial absence of conditioner
build-up on the hair. The three essential ingredients are completely
compatible.
The PVP/VA copolymer, which is one of the essential components of
present invention, is a substantially water insoluble film orming
material which has been used in the prior art in hair sprays,
liquid or foam hair setting composit ~ s and the like. Suitable PVP/
YA copolymers are obtainable from the AF Corporation in the form
of a 50~ A.I. (active ingredient) clear liquid solution in either
ethanol or isopropanol at room temperature, with the weight ratio of
PVP/VA varying from 70:30 to 30:70. For example, PVP¦VA E-735 is
a 50% ~AI) solution in ethanol of PVP/VA in ~he weight ratio of
1 70:30; PVP/VA E-335 is a 50~ (AI) solution in ethanol of PVPlVA
in the weight ratio of 30:70 and PVPiVA I-735 i3 a 50% (AI) solution
in isopropanol of PVP/VA in the weight ratio of 70:30. The aleohol
1, solutions of the PVP/VA copolymers exhibit water tolerance, thereby
enabling their use in aqueous sys~ems such as aqueous condit:ioning
tompositions. For example, the water tolerance of PVP/VA copolymers
of the E-Series, expressed in parts of water added to 100 parts of
,~ a 25% copolymer solution in anhydrous e~hanol until the appearance
!j of a slight haze, is as follows:

In use, a clear f1lm of PVP/VA copolymer is deposited on the hair
treated with composit1ons containing such polymers to provide
hair with a high luster. The PVP/VA copolymer is used in amounts
of about 0.570 to 15Yo~ preferably 0.9% to 10% and most preferably 1.35%
to 3% by weight of t~he compo~1clon.
I ~ lAnother essential ingredient in the novel hair rinse composition
I ¦is a cationic quaternary ammounium compound which exhibits at least ~ ~;
I ; l part1al soIubility in water. Such compounds do not contain a hydro~
phobic alkyl or alkenyl group of at least eight carbon atoms in their
molecular structure like the traditional condit1oning quaternary
ammonium compounds such as cetyl or stearyl dimethylbenzyl ammonium
chloride, bu~ contain a polyoxyalkylene radical of at least nine
carbon atoms in their molecular structure. Because of this difference,
l these compounds exhibit solubility in water varying from complete
¦ water solubility for compounds containing a relatively low number of
l C3-C4 alkylene oxide groups, e.g., eight propylene oxide groups, to
I partial solubility in water for compounds containing a higher number of
i said alkylene oxide groups, e.g., twenty-five or forty-one propylene
oxide groups. These ingredients exhibit cationic surface
,
~l~7~5
functionality in both oil and ~ater, with the lipophilic tendency being
proportional to the amount of polyether structure comprising the indi-
vidual compound'~ molecular weight. A high order of antistatic
efficiency is due to the combined effects of their cationic activity
and the hygroscopicity of their polyether structures.
Suitable compounds generally correspond to the following formula:
R ~
, l
~ Rl - N - X A
_ ~ _
whereinlR and Rl each is an alkyl radical containing l - 3, preferably
1 - 21 carbon atoms; R2 is represented by either [CH2CH(R4)0] H or
alkylene 0 ~CH2CH(R4~0]nH where R4 is an alkyl radical of 1 - 2
carbon atoms, preferably methyl,~n is 3 to 60, preferably 9 to 41, and
alkylene contain~ no~ more than three carbon atom~; X is a lower alkyl
or alkenyl radical containing l ~o 4 carbon atoms or is an alkaryl
radical containing from 7 to 9 carbon atoms; and A is an anion
selected from the group consistinp of chlorine, bromine, hydroxy,
sulfate, metho-or etkosulfate, nitrate, phosphate, acetate, formate
and sulfonate, preferably chlorine or bromine. Particularly preferred
compounds are methyl, diethyl, polyoxypropylene (8 - 41) quaternary
ammonium chlorides. These preferred c mpounds may be purchased from
Witco Chemical Company under the ~ 1 CC9 (quaternium 6j
containing 9 moles of propylene oxide; Emcol CC-36 ~quaternium 20)
containing about 25 moles of propylene oxide: and Emcol
CC-42 (quaternium 21) containing 41 moles of propylene
oxide.

5~5S
The method oE making these c~uaternary ammonium
compounds is described in United States Patents Nos~ 3,141t905,
3,155,591 and 3,123r641.
Because of the substantivity to the hair of the fore-
going quaternary ammonium compounds, said compounds appear to
coact with the PVP/VA film forming ingredient to yield treated
hair with an adherent lustrous film that can be readily removed
by washing with a shampoo. In addition, these ingredients are
essentially non-irritating and are compatible with anionic and
nonionic surfactants as well as with phenolic germicides. The
cationic polyoxyalkylene quaternary ammonium compounds
constltute about 0.1% to;10%, preferably 0.45% to 8%, most
preferably 1.35% to 3~ by weight of~the hair conditioning
composition. Furthermore, the weight ratio of these cationic
polyoxyalkylene quaternary ammonium compounds to the PVP/VA
polymer ingredient should be controlled in the range of 1:5 to
20:1, preferably from l:3 to 2:1.
The third essential ingredient in the hair condition-
ing compositions is a water-soluble, nonionict cellulose
~ polymer which functions both as a thickening~agent and as a
conditioning agent. Suitable cellulosic polymers are selected
from the group consisting of hydroxyethyl cellulose and
hydroxypropyl methyl cellulose, with hydroxyethyl c~llulose
being preferred. Hydroxyethyl cellulose is the product of
reaction between an alkali cellulose and ethylene oxide, and
such products are available in a number of viscosity grades.
Viscosity is primarily dependent upon the viscosity of the
cellulose used in the reaction. The degree of substitution of
hydroxyethyl groups per
-- 11 -- ,
~75~.,s
62301-l407
ylucose unit is l.4 ~ 1.5 ancl these hydroxyethyl celluloses
have an average molecular weight range ~rom about 80,000 to
about 900,000. A particularly preferre~ hydroxyethyl cellulose
i5 available under the trade-mark ~atrosol 250 HR from
~ercules, Inc.. Water-soluble hydro~ypropyl methyl cellulose
has a metho~yl content between about 25% and about 32~ by
weight and a hydroxypropyl content between about 2% and 10%,
preferably 2~ to 7~, by weight. Again, the chain length of the
~ l0 cellulose used in the reaction can be controlled to provide a
- molecular weight which yields a viscosity for a 2~ solution in
water in the range of l0 cps and 5000 cps, preferably 50 cps to
4000 cps.
These cellulose polymers provide stability to -the
compoqition upon aging by viscosity control. The composition
retains its viscosity without thinning out or thickening. In
addition to controlling the viscosity o the aqueous hair
rinse, the cellulose polymer contributes to its conditioning
properties. It appears that hydrogen bonding occurs between
the water soluble nonionic cellulose polymer and the cationic
quaternary compound, resulting in additional conditioning bene-
fits to the hair rinse. This unexpected dual ~unction and
coaction with the other two essential conditioning ingredients
provides a uniquely superior hair rinse product. The cellulose -~
polymer content constitutes about 0.1-4~, preferably 0.2% to
2~, most preferably 0.25~ to l.2~, by weight of the condition-
ing hair rinse composition.
The final essential ingredient in the conditioning
hair rinse compositions is an aqueous medium which is primarily
water. Since the PVP/VA polymer is usually supplied as a solu-
tion in ethanol or
q~ - 12 -
.1
r--
isopropanol, the aqueous medium usually contains a minor amount of a
C2-C3 alkanol . Furthermore, if desired, additional amounts of C2-C3
alkanol may be added to the composition, particularly where the
composition is sold in the form of a "mousse." The proportion oE the
aqueous medium is in the range of 71% to 99.3%, preferably 80% to
98.3%, most preferably 90% to 97.7%, by weight of the hair rinse
composition. Usually, the C2-C3 alkanol will be a minor proportion
of the aqueous medium, ranging from 2% to 25% by weight of the hair
rinse composition, with the higher amounts of such alkanol being
present in the "mousse" compositions.
An optionally desirable component in present hair conditioning
composition is a oaming cationic surfactant which functions as a
dispersant and contributes to ~he conditionin~ properties of the
: ~ :
~ final product. This cationic surfactant is a hydroxylated
., .: :.
quatarnary ammonium compound containing polyethoxy radicals, a
gluconamidopropyl radical, or a hydroxylated glucona~ido Cl-C3 alkyl
radlcal attached to the nitrogen atom, at a coneentration of 0~1~ to
8~, preferably 0.5% to 4~, by weight.
,A typical hydroxylated cationic quaternary ammonium compound
jl containing a gluconamidopropyl radical is Quaternium 22
gluconamidopropyl dimethyl 2-hydro~yethyl ammonium chloride).
Quaternium 22 is a water soluble gluconamidopropyl quaternary salt
r~
which can be obtained from the Van Dyke Company under the ~tYKk~nh
Ceraphyl 60 in the form of a clear yellow to light amber liquid
¦ containing 58%-62% by weight of said salt in water, having a pH of

polyethoxy radicals is Quaternium 36 (stearyl pentaethoxy
ammonium chloride) which may be obtained from the Hoechst
Company under the trademark Genamin KS-5 in the form of a
clear yellow liquid containing 20%-22% by wei~ht of said
quaternary salt in water. The pH of Genamin KS-5 is 6.5 ~ 0.5.

The hair conditioning compositions in accordance with
this invention may be in the form of a clear or opaque pourable
li~uid, gel or liquid under pressure for use either as a hair
rinse af-ter shampooing or as a hair conditioning-styling
mousse. The viscosity of the final product may range from at
least 50 centipoises to up to 20,000 cent.ipoises, preferably
500 to 8,000 centipoises, and such product may be in the form
of a liquidl a viscous lot`ion or a cream. The hair conditioning
product in the form of a gel may be packaged in and extruded
from a squeeze tube or any suitable container by applying
pressure. Thus, the product may be in the form of a liquid ~: .
under pressure packaged in an aerosol container containing
propellant, a package that is particularly useful for hair
styling mousses. In lieu of the aerosol container, the .~ ~ :
conditioning product also may be packaged in a squeeze spray .
container. .
The pH of the hair conditioner of present invention
is acidic and ranges from about 3-6, preferabl~ about 4-5.
The hair conditioning compositions of this invention
also may contain conventional additional components such as
: colouring agents, perfumes, preservatives such as formaldehyde
(formalin), brighteners such as Uvinul*, cationic hydrophobic
quaternary ammonium compounds, and other polymers such as
copolymers of polydimethylsiloxane and a polyoxyalkylene ether.
The total weight of these optional additives usually does not
exceed 5~ by weight of the composition and preferably does not
exceed 2% by weight of the composition.

The present hair conditioning compositions are readily made by
mixing the ingredients in the prescribed manner. For example, a
preferred method of preparing the present compositions comprises the
steps of forn~ing a thick uniform dispersion of hydroxyethyl
cellulose by mixing the hydroxyethyl cellulose in cold water,
heating the dispersion to about 60C. until thick and thereafter
cooling to 49C.; sequentially admixing the quaternary ammonium
compound(s) (Quaternium 21, Quaternium 22 and Quaternium 36) and
the PYP/VA copolymer with said disper~ion; cooling the mixture to
38C.; adding thereto the colorant, perfume, formalin and other
optional additives with agitation and cooling the resultant
mixture to room temperature (24C.) thereby forming an opaque or
~1 clear product. Instead of sequent1ally add1ng the cationic
'1 quaternary compound~s) and the PVPtVA copolymer, said compounds
~ may be premixed and added as a premix to the thick aqueous .
¦ hydroxyethyl cellulose dispersion.
These hair conditioner produc~s have une~pected superior
properties due to the coaction of the speGific ternary combination
I of PVP/VA copolymer, the cationic quaternary compound ha~ing a
I polyoxyalkylene group attached to the nitrogen atom and the
nonionic water soluble cellulose polymer. The noYel hair condi-
tioner compositions proYide a dry feel, very good body and superior
high luster properties.to the hair treated therewith and eliminate
the dulling of clean hair resulting from the use of conventional
hair conditioners. In addition, the inventi~e conditioners
exhibit comp}ete wash-o~f with shampoos, whereas con~entional
S~5S
6230L-1407
conditioning hair rinses or hair mousses are retainecl, thereby
resulting in an undesirable build-up of condit~oner on the
hair. Consequently, continual usage oE the conventional hair
conditioners dulls the hair. Present products have eliminated
this problem. Addi-tional conditioning benefits imparted to the
hair include very good wet and dry combing, very good manage-
ability and good antistatic properties.

Mousse products of Examples 8 and 9 have light to moderate hold
propertles as compared to the commercial control product. However,
j compositions 8 and 9 provide better ease of application, easier comb-out
" and better o~erall appearance than the control mousse. Slightly less
i shine properties were found with E~ample 9 which was probably caused .by
the presence of the betaine used to produce bet~er foam psoperties. The
product of Example 10 had the best overall conditioning properties
including the best foaming and discharge properties.
, In Examp1es 8-10, a C3-C4 hydrocarbon propellant is present as an
Il essential ingredient in proportions of 3~ to 20%, preferably 5% to 15%,
,¦ by weight of the ultimate mousse composition. In the mousse products,
.! the inclugion of the propellant ~ypically reduces the proportion of the
other essential ingredients on a pro rata basis because the normal
procedure is to admix 80 to 97 parts by weight of the conditioning
composition with 3 to ~0 parts by weight of propellant in an aerosol
ontai~er.
