Abstract
The invention provides a cleansing composition, which comprises in addition to water, (a) from 10 to 30% by weight of one or more C.sub.6 to C.sub.16 acyl lactylates and (b) from 5 to 25% by weight of one or more co-surfactants, such as acyl taurates, isethionates, sarcosinates and sulphosuccinates. The cleansing compositions are primarily intended to be used as personal washing products, such as facial wash foams, bath foams and hair shampoos.
Claims8
A cleansing composition which comprises, in addition to water,
- (a) from 15 to 35% by weight of one or more acyl lactylate(s) of the following structure (1) ##STR23## where R.sup.1 CO represents a C.sub.6 to C.sub.16 acyl radical;
- a is an integer from 1 to 3;
- M.sup.1 represents hydrogen or a counterion chosen from alkali metal, ammonium or a substituted ammonium group having one or more C.sub.1 to C.sub.3 alkyl or hydroxy alkyl group (s );
- and
- (b) from 5 to 25% by weight of one or more acylisethionates of the following structure (3)
- R.sup.3 CO--OCH.sub.2 CH.sub.2 --SO.sub.3 M.sup.3 ( 3)
- where R.sup.3 CO represents a C.sub.10 to C.sub.18 acyl group;
- and M.sup.3 is as M.sup.1 in structure (1);
- the composition having a foam height of more than 150 mm, as measured by the Foam Height Test, ASTM D 1173-53.
