peroxygen bleach, 5~lcp~nd~d ln a specific watPr/solvent
medium, which medium was found to give the requir2d
~;c~l stability to the composition.
In such compositions however, particular attention has
to be given to the physical stability of susr,end2d
i~ particles in the liquid medium.
.
One option is eprPsented by e.g. copending U.~.
Application No. 8926620.9, descri~ing liquid d2t2rsent
compositions in which solid particles, in particular
particlss of a peroxygen compound, are suspended by means
of a structured surfactant phase tsurfactant "neat phas2").
ere is a need, however, for suspending systems which
involve easier ~loc~sci~g, compared to ~Lu~uL~d
surfactant phases.
Although not for the ~UL~oS~ of sUcp~n~;n~ peroxygen
bleach particles, strucLul~d surfactant phases have been
described in variou_ patent ~ S; In particular
E~-A-79 646, EP-A-86 614, EP-A-203 660 and~EP-A-295 021
describe liquid detergent compositions containing suspended
builder particles where one or more "salting-out"
electrolytes, or i'surfactant desolubilizing" electrolytes
are used, to build ~L u~Lured phases with the surfactant
materials;
; Such electrolytes includej among many other substances,
silicates, and need to be used at substantial levels, i.e.
above 5%, in o~der 'o perform their~"salting-out" effect.
Other patent doc~ nts disclosing ~h8 use of silicates
in cle~ning/detergent compositions of the suspending type
include G~-A-2031455, and GB-A-1342612 wherein the solid
materials to be s .cp~n~d include abrasives and

T.~at2r-insolubl2 phosphate h~ Pr salts, but do not

GB-A-2158453 which mentions perborate as a possible
~l~aching ~rgr~dient in liquid c ,itions of the
suspendirAg t~pe specirically advocates that the
comDositioms must -e free of silicate', and instead must
contain ~ c-a~o~Ilic antigelling agent.
Silica.es nave also '~een widely described as
alkalinity-building ingredients of aqueous thixotropic
li~uid'c~.~osilions used for e.g. automatic dishwashing
pUrpOSQS. ~epres2ntatiYs of this art is EP 315 024,
disclosing levels of silicate in the range of 25~ to 40%.
It has naw surprisingly been found that low levels of
silicate can effi~ ntly ~-~P-,-~ peroxygen-bleach particles
in liquid de~e~yer.L compositions of the type described in
EP-A-293 040, with only a l~a~e increase in~the
viscosity of the composition.
The present sllcp~n~ion system does not involve any specific
processing ~iLLicul~y; 'u~-th~rmore the presence of silicate
brings such advantages as increased alkality and increased
washing-machine compatibility.
e present invention therefore provides perfectly
phase-stable aqueous liquid detergent compositions
cont~;n;n~ a solid peroxygen bleach c ~ ', a.liquid
phase consisting of water and a water-miscible organic
solvent, and lo~b~ levels o~ silicate to suspend the

SummarY
m e present invention relates to s~able liquid
deterg2n~ com~ositions having a pH of at least 8 and less
than about 11, comprising a solid, water-solubIe pzro~g
~ suspended in a liguid phase containing water and
at least one T~ater-miscible organic solvent, the amount o~
the solid water-soluble peroxygPn compound being such ~ha~
the amount of available oxygan provided by said peroxlgen
c _ ld is from 0.5% to 3%, said compositions containing
from 0.5% to 5%, preferably I% to 3%, by weight of
silicate.
~etailed Description
The water-soluble pe~uxY5~sl~ c , ~-d
The water-soluble solid peroxygen ~ n~5 is present
in the compositions herein pref~rably at 1eYe1S of from 5
to 50% by weight of the total composition, more preferably
from 5 to 40%, even more preferably from 5% to 30%, most
praferably from 10~ to 30% by weight.
Examples of suitable water-soluble solid peroxygen
,_ m~c include the peLLuL~es, persulfates,
,ox~Slisulfates, y~L~hn~h~teS and the crystalline
peroxyhydrates formed by reacting hydrogen peroxide~with
sodium carbonac_ (forming percar~onate) or urea. Pre~erred
peroxygen ble~ach c ,_~-dç are perborates and
per~rhon~tes.
Most prererred in the present context is a perborate

pr ferably 3 to 15 micrometers.
The small ~ rage ~article size can best be achieved by
in-situ cxys.~lii~acion, t~pically of perborate
monohydra~e.
In-sltu c~ystallization encom~s~ processes involving
-dissoiu~lon ar.d rec-~ys~allization, as in the dissolution of
perborate monohydrate and subsequent formation of pel~,dLe
tet-ahydrate~ ~ec~s~ ;7ation may also take place by
allowi.-~ p2 ~_rat~ monohydrate to take up crystal water,
whereby the monohydrate directly recrystallizes into the

The water-miscible organic solvent
~ he suspansion system for the solid peroxygen component
hereln consists in a-liquid phas2 tha_ comprises water and
a water-miscible organic solvent. This makes it possih~e
to in~uL~o-~te in the liquid detergent ~ ~sitlons herein

0.1%. Less than one tenth of the total amount of peroxygen
c~ d is d~ssolved in the liquid p;nase; the low level of
available oxygen in solution is in fact critical for the
stability of the syst2m.

m e standard icdometric methcd (as described for
instanca in ~ethoden der Or~n;~rhPn Chemia, Houben Weyl,
1953, Vo. 2, page 562) is suitable to deter~ine tne
aYaila~le o~gPn (AVO) content of the composition.
In order to ~nsura complet~ ~quil~bration between
liquid and solid phases, the compositions are to be kept
after mixing ror thrae days at room temperature b~LoL~ the
~VO titration. ~efore measuring ~he products are
thoroughly shaken in order to ensure correct sa~pling.
For the det~rm;n~tion of the available oxygen (AVO) in
the liquid phase, s~les of the compositions are
centri~uged for 10 minutes at 10.000 rpm. The liquid is
then s~a-~ed from the solid and titrated for available
oxygen.
It is not nPc~e~y that the organic solvent be fully
mlscible with water, provided that enough of the sol~ent
mixes with the water of the composition to affect the
solubility OL ~h2 p~roxygan ~ ~o~d in the descri~ed
manner. Fully water-soluble solvents are preferred for use
herein.
.
- Ihe water-misci~le organic sol~ent must, of course, be
compatible with the peroxygen hleach c~mpound at the pH
that is used. Therefore, polyalcohols having vicinal
ydluxy groups (e.g. 1,2-propanediol and glycerol~ are less
' desirable when the peroxygen bleach co~ol~n~ is perborate.
Examples of suitable water-miscible organic solvents
include the lower a}iphatic monoalcohols; ethers of
diPthylene glycol and lower monoaliphatic monoalcohols;
specirically ~thanol, n-propanol; iso-propanol; butanol;

largsly ~ste~ ~ed by the ratio water:organic solvent. It
is not necPss~ry however to use more organic solvent than
is needed to keep the amount of available oxygen in
solution below 0.5%, preferably below 0.1%.
In practical terms, the~ratio water:organic solvent is,
for most systems, in the range from 5:1 to 1:3, preferably
from 4:1 to 1:2.

The silicates are present in the present c -~;tion at
levels or from 0.5%-to 5%, preferably from 1% to 3%. The
addition of silicates at such low levels cannot promote the
formation of a structured surfactant phase, but
surprisir.gly allows for an efficient and stable s~1CpPnCi ~n
of the peroxygen bleach particles, with only a moderate
increase in the viscosity of the composition.

The silicate materials for use-herein can be natural
silicates with a ratio of SiO2 to Na~0 of from 1:1 to
4:1, preferably 1:1 (metasilicate), 1.6:1 or 2:1.

The nonionic surfactants are convention~l1y produced by

reactive hydrogen atom, e.g., a hydroxyl, carboxyl, or
amido group, in the presence of an acidic or basic
catalyst, and include compounds having the general formula
RA(C~2CH2Q~nH wherein R represents the i~dluphobic
moiety, A represents the group carrying the reactive
hy~ atom and n represents the average number of
ethylene oxide moletles. R typically contains from about 8
to 22 carbon atoms. They can also be formed by the
