Abstract

A conditioning shampoo composition comprises, as the conditioning agents thereof, from 0.1 to 4.0 % by weight of one or more dimethicone copolyols having an ethylene oxide/propylene oxide (EO/PO) ratio of from 20/80 to 80/20 and from 0.5 to 4.0 % by weight of one or more non-ionic emulsifiers having a HLB of from 8 to 12 and which do not affect the foaming property of the shampoo.

Description

S~ Poo COMP0S~TIONS
.'~n'~ lnvention ~s conce_ned with shampoo csm~ SS ~ o, a ~a ilu~arly, with conditioning sh~ c_s, ~h-~ is s~ oos which have ~oth the usual cleaA,si.lg ac;ion and also a conditioning action. The use of such shampoos avoids the necessity for the separ~t~ u~e of a hair conditioner after the hair has been washed with a conventional shampoo having only a cleansing action.
Whilst conditioning shampoo compositions are known, a disadvantage that arises with some of them is that on repeated use, there is a ~uild up of the conditioning ingredients on the hair so that the washed hair no longer feels pleasant to the user.
Conditioning shampoos have also been described and are co--ercially available which do not suffer from this disadvantage, that is the build up of conditioning agents. Such shampoo compositions are described for example, in U.S. Patents 4,704,272; 4,741,855: and 4,788,006 and in British Specifications 2,192,194A and 2,196,980A.
An object of the present invention is to provide alternative conditioning shampoo compositions which are not subject to the significant build up of conditioning ingredients on repeated use.
Ne have found that these requirements can be met ~y using a -ombination of certain dimethicone copolyols and certain non-ionic emulsifiers having an HLB of from 8 to 12 as the conditioning agents in a W092/lO990 2 0 9 8 3 9 1 PCT/US91/09245 -.

shampoo composition which may, in other respects, be conventional.
According to the prss2nt invention, there is provided a conditioning shampoo composition which comprises, a5 the conditioning ag-nts th~r~of, f~rm O.' to 4.0% by weight of one or more dimethicone copolyols having an ethylen2 oxide/propyl~nQ oxid~ (E0/~O) ratio of from 20/80 to 80/20 and from 0.5 to ~.0% by weight or one or mors non-ionic emulsifiars having an XL3 of r~o~
8 to 12 and wh.ich do not affec. the ~oaminy ~rQpert~ 0 5 A . .~

where n, m, x and y are integers. The dimethicone copolyols used according to the invention have values of x and y such that the ratio x:y, that is the E0/P0 ratio, is from 20/80 to 80~20.
Preferred dimethicone copolyols contain from 60 to 140 SiO2 units, that is the sum of n and m is from 60 to 140.
The dimethicone copolyol constituent of the shampoo composition preferably comprises a major proportion of a dimethicone copolyol having an E0/P0 ratio of from 80/20 to 70/30 and a minor proportion of a dimethicone copolyol having an E0/PO ratio of from 20/80 to 40/60.
Suitable dimethicone copolyols for use in the shampoo compositions according to the invention are available, for example, from Th.Goldschmidt AG, of 3~ Essan, Germany under the Trade Mar~ "Abil". A pref2rr2d dimethicone copolyol having an E0/PO ratio of 77/23 is available as "Abil" B88183 and a preferred dimethicone W092/10~0 2 ~ 9 ~ 3 9 1 PCT/US91/09~5 copolyol having an E0/PO ratio of 20/80 is available as "Abil" B8852; these two materials both contain about 60 Sio2 uni~s. .~ ~raferr2d dimethicone copolyol having an ~o~0 s~io of ~0/60 and containing about 140 SiO2 units i~ s '.~ gll.
We have found that the extent of deposition of ths ~ ~.3~icone copolyol can be controlled by using it in conjunction with the non-ionic emulsifier having an ~ o~ 3 ~o 1 ; in ~his way excQssive build up of lo ~ co-~d~ on~.~.g ~ en~ on ~p~at~d uss of th~ shampoo O~An ~ d . ~'' e ~ a~ 3~ a~oun~ of ~he non-ior.ic 3mulsifi~ s2d, i~ r~la~ion to a given amount o.' d~ ni__ne co~olyol, ~ha la s o. ~he latter is left on ~ h~ir.
~or any particular choice of dimethicone copolyol(s) and non-ionic emulsifier(s), the optimum proportions of these two ingredients to obtain the desired deposition of dimethicone copolyol on the hair can be readily established by routine experimentation.
By way of example, using a preferred combination of dimethicone copolyols as referred to above and the particularly preferred non-ionic emulsifier referred to below, we have found that an optimum level of dimethicone copolyol deposition is obtained by using 1.5% by weight of the non-ionic emulsifier and 1.1% by weight of the dimethicone copolyol combination.
Preferrad non-ionic emuisifiers having an HLB
of from 8 to 12 for use in accordance with the invention are:

Of these, PEG40 sorbitan hexaoleate is particularly preferred.
T~e ch~mroo c~,osition according to the invention will contain cleansing agents which may be any of the anionic, cationic, amphoteric and non-ionic surfactants conventionally used in such compositions, these ingredients being used in the conventional proportions. The composition can, and usually will, contain further ingredients which provide particular desired characteristics or properties to the composition.
Suitable ingredients for shampoo compositions according to the invention are, for example, as follows:
Cleansing agents It is preferred that the cationic component of the surfactants included in the composition should be one or more quaternary ammonium salt surfactants. A

Thic.~on~rs Suitabl2 thic~enors include, for example, hydroxypropyl methyl cellulose and talloweth 60 myristyl glycol; the proportion of thicken~r is suitably from 0.1 to 2.0% by weight, depen~;~g on the type of thick~ner used and the required viscosity.
Hair bodying agents Suitable agents for imparting body to the hair include, for example, cetyl alcohol and lauric acid monoglyceride; these agents are suitably used in a proportion of from 0.50 to 1.50~ by weight.
Other conventional ingredients which may be and preferably are incl~ded in the shampoo composition are: a hyd~o--o~e, such as ammonium xylene sulphonate, to prevent daposition in hard water areas of undesirable materials on the hair; pearlising agents; preservatives;
pH ad~usters, such as lactic acid; colourants; and perfumesA
