Abstract

Claims (32)

1 . A cosmetic cleansing preparation, wherein the preparation is suitable and formulated for use in the shower and comprises, based on a total weight of the preparation,

(a) from 0.5% to 8% by weight of anionic and/or non-ionic surfactants,

(b) from 2.5% to 7% by weight of amphoteric and/or zwitterionic surfactants, and

(c) Caesalpinia spinosa gum,

and wherein no homopolymers or copolymers of acrylic acid are present, and Caesalpinia spinosa gum and optionally, xanthan gum, are the only natural polymeric thickeners in the preparation.

2 . The preparation of claim 1 , wherein the preparation comprises one or more anionic surfactants of formula (I):

RO—(CH 2 CH 2 O) x —(CH 2 —CHR 1 O) y —(CH 2 CH 2 O) z —SO 3 -M +   (I)

wherein

R is a linear or branched C 8 -C 18 -alkyl radical or a mixture of different linear or branched C 8 -C 18 -alkyl radicals;

R 1 is a methyl, ethyl or a mixture thereof;

M + is a cation selected from alkali metals, NH 4+ and HNR 2 3 + , wherein R 2 is selected from linear or branched alkyl radicals, CH 2 CH 2 OH and CH 2 CH(OH)CH 3 ;

x is 0 or an integer of 1-3;

y is 0 or an integer of 1-10; and

z is 0 or an integer of 1-30.

3 . The preparation of claim 1 , wherein the preparation comprises sodium laureth sulfate and/or ammonium laureth sulfate.

4 . The preparation of claim 3 , wherein no non-ionic surfactants are present.

5 . The preparation of claim 1 , wherein alkyl glycosides are present as non-ionic surfactants.

6 . The preparation of claim 5 , wherein decyl glycoside and/or coco glycoside are present.

7 . The preparation of claim 6 , wherein a proportion of the alkyl glycosides is from 0.5% to 5% by weight, based on a total weight of the cleansing preparation.

8 . The preparation of claim 5 , wherein no anionic surfactants are present.

9 . The preparation of claim 1 , wherein the amphoteric and/or zwitterionic surfactants comprise one or more of sodium cocoamphoacetate, disodium cocoamphodiacetate, sodium cocoamphopropionate, disodium cocoamphodipropionate, coco betaine, lauryl betaine and/or cocamidopropyl betaine.

10 . The preparation of claim 9 , wherein cocamidopropyl betaine is present at a concentration of from 2.5% to 7% by weight, based on a total weight of the cleansing preparation.

11 . The preparation of claim 9 , wherein besides cocamidopropyl betaine no other amphoteric and/or zwitterionic surfactants are present.

12 . The preparation of claim 1 , wherein Caesalpinia spinosa gum is present in a concentration of from 0.1% to 1% by weight, based on a total weight of the preparation.

13 . The preparation of claim 12 , wherein the concentration of Caesalpinia spinosa gum is from 0.2% to 0.4% by weight.

14 . The preparation of claim 1 , wherein the preparation comprises xanthan gum.

15 . The preparation of claim 14 , wherein the preparation comprises from 0.01% to 0.3% by weight of xanthan gum.

16 . The preparation of claim 1 , wherein no other natural polymeric thickeners are present.

17 . The preparation of claim 1 , wherein the preparation comprises PEG-7 glyceryl cocoate.

18 . The preparation of claim 1 , wherein the preparation further comprises sodium chloride.

19 . The preparation of claim 1 , wherein the preparation comprises PEG-200 hydrogenated glyceryl palmate, PEG-40 hydrogenated castor oil and/or PEG-90 glyceryl isostearate.

20 . The preparation of claim 19 , wherein a total concentration of PEG -200 hydrogenated glyceryl palmate, PEG-40 hydrogenated castor oil and/or PEG-90 glyceryl isostearate is from 0.1% to 1.5% by weight, based on a total weight of the cleansing preparation.
