The present inuention relates to liquid deterg~nt
compositions which contain a solid, water-soluble peroxygen
bleach compound. The compositions herein contai~ a sol~ent
system comprising water and a water-miscible organic
sol~ent. The sol~ent system is designed to keep the amount
of auailable oxygen in solution below 0.5%, preferably
below 0.1%. The amount of a~ailable oxygen in the liquid
phase corresponds to not more than one fifth of the total
amount of peroxygen bleach in the composition, preferably
to not more than one tenth.

So-called hea~y duty liquid detergent compositions
cornmercially auailable at present typically comprise
organic sur~actants, enzymes, and perfumes. These
components are ge;nerally-incompatiblP with peroxygen
bleaches. ~s a result, no peroxygen bleach containing
liqwid detergent compositions are commercially auailable
to date.

Summary of the In~ention
The liquid detergent compositions o~ the present
in~ention ha~e a pH of at least 8, which compris~ organic
surfactants and which fwrther comprise, by weight of the
composition, an amount of a solid water-soluble peroxygen
compownd dispersed in a liquid phase which comprises a
sol~ent system cornprising water and at least one
water-miscibl0 organic soluent, such that the amount of
a~ailable oxygen (~0) dissol~ed in the liquid phase is
not greater than 0.5%, preferably not greater than 0.1%,
by weight of the liquid phase. The amount of available
oxygen dissol~ed in the liquid phase corresponds to not
more than one fifth of the amount of peroxygen compound of
the composition, preferably to not more than one tenth.
Preferred herein are detergent compositions ha~ing a
pH of at least 9, more preferably at least 9.5.
The preferred solid, water-solubla peroxygen compounds
are the perborates. The preferred water-miscible organic
sol~ents are the low molecular weight monohydric alcohols;
the most preferred of these sol~ents is ethanol.
Preferred are also liquid detergent compositions that
further comprise detergent enzymes.
Detailed Des~ption of_th _In~ention
The present invention addresses the problem of
formulating a liqwid detergent composition that contains
significant amounts of organic surfactant, including
anionic surfartants, and of a solid, water-soluble
peroxygen bleach, and that is stable. It has now been
disco~ered that this may be achie~ed by the use of a
~3l~a~7
-- 4 --
sol~ent system that comprises water and a water-miscible
organic sol~ent. This makes it possible to incoporate in
the liquid detergent composition a significant amount of
the peroxygen compound, while keeping the amount of
a~ailable oxygen in solution below 0.5% by weight of the
sol~ent system, preferably below 0.1%. Less than 1/5 of
the peroxygen co~pound is dissol~ed in the liquid phase,
preferably less than 1/10.
The presence of water in the sol~ent system is
essential for the solubility of, e.g. anionic surfactants.
The low le~el of a~ailable oxygen in solution has been
found to result in a bleach system that is stable upon
storage under typical storage conditions.
The liquid detergent compositions are formulated at a
pH of at least 8, preferably of at least 9, more prefer-
ably at least 9.5. The alkaline pH is conduci~e to a good
bleaching action of the peroxygen compound, particularly
when the peroxygen compound is a perborate. Ne~ertheless,
the stability of the bleach system in an aqueous liquid of
alkaline pH is surprising. ~t lleast some of the available
oxygen in solution is assumed to be present in the form of
hydrogen peroxide. It has been found that hydrogen
peroxide is not sufficiently stable in the sol~ent systems
of the liquid detergent compositions of the present
inuention. Yet, the solid, water-soluble peroxygen
bleaches haue been found to be stable therein. ~pparent-
ly, the low le~el of a~ailable oxygen in solution is
rritical for the stability of the system.
Examples of suitable water-soluble solid peroxygen
compounds include the perborates, persulfates, peroxy-
-- 5 --
disulfates, perphosphates and the crystalline peroxyhydra-
tes ~ormed by reacting hydrogen peroxide with sodium
carbonate or urea. Preferred peroxygen bleach compounds
are sodium perborate monohydrate and sodium perborate
tetrahydrate.
The standard iodometric method ~as described for
instance in Methoden der Organischen Chemie, Houben Weyl,
1953, ~o. 2, page 562) is suitable to determine the
auailable oxyg~n (~O) content of the composition.
In order to ensure complete equilibration between
liquid and solid phases, the compositions are to be kept
a~ter mixing for three days at room temperature before the
~UO titration. Before measuring the products are
thoroughly shaken in order to ensure correct sa~pling.
For the determination of the a~ailable oxygen ~UO) in
the liquid phase, samples of the compositions are
centrifuged for 10 minutes at 10.000 rpm. The liquid is
then separated from the solid and titrated for available
oxygen.
It is not necessary that the organic soluent be fully
miscible with water, provid~d that enough of the sol~ent
mixes with the water of the composition to affect the
solubility of the peroxygen compound in the described
manner~ Fully water-soluble solvents are preferred for
use herein.
The water-miscible organic solvent must, of course, be
compatible with the peroxygen bleach compound at the pH
that is used. Therefore, polyalcohols having uicinal
hydroxy groups (e.g. 1,2-propanediol and glycerol) are less
desirable when the peroxygen bleach compound is perborate.
~ ~3~9~77
Examples of suitable water-miscible organic soluents
include the lower aliphatic monoalcohols; ethers of
diethylene glycol and lower monoaliphatic monoalcohols;
specifically ethanol, n-propanol, lso-propanol, butanol;
polyethylene glycol (e.g., PE~ 150, 200, 300, 400);
dipropylene glycol; hexylene glycol; methoxyethanol;
ethoxyethanol; butoxyethanol; ethyldiglycolether; benzyl-
alcohol; butoxypropanol; butoxypropoxypropanol; and
mixtures thereof. Preferred soluents include ethanol;
iso-propanol, 1-methoxy2-propanol and butyldi-
glycolether. ~ preferred sol~ent system comprises
ethanol, and a co-sol~ent ha~ing a higher flash-point than
ethanol.
~ lthough the presence or absence of other ingrediants
plays a role, the amount of auailable oxygen in solution
is largely determined by the ratio water:organic soluent.
The smaller this ratio ti.e. the more organic sol~ent is
used in the sol~ent sytem), the lower the amount of
a~ailable oxygen in solution. ~:Lthough this is good for
stability of the bleach system, -lt is less desirable for a
good solubility of other componellts (e.g. electrolyte,
anionic surfactants). In any e~ent, it is not necessary
to use more organic soluent than is needed to keep the
amount of auailable oxygen in so:lu~ion below 0.5%,
preferably below 0.1%.
In practical terms, the ratio water:organic sol~ent is,
for most systems, in the range from 8:1 to 1:3, preferably
from 5:1 to 1:2.
The liquid detergant compositions herein contain from
5% to 60% of the liquid detergent composition, preferably
from 15% to 40% of an organic surface-acti~e agent selacted
from nonionic, anionic, and zwitterionic surface-
acti~e agents and mixtures thereof.
