Abstract
The present invention relates to a series of novel silicone phosphate esters which mitigate eye and skin irritation when used in synergistic combinations with fatty alcohol sulfates and fatty alcohol ether sulfates. These materials form complexes which have surprisingly low irritation properties.
Claims9
A process for the mitigating of irritation which comprises application to the skin of an effective irritation mitigating amount of a complex of the following formula;
- ##STR6## wherein R is ##STR7## a is an integer from 0 to 200;
- b is an integer from 0 to 200;
- c is an integer from 1 to 200;
- R.sup.1 is CH.sub.3 ;
- n is a n integer from 0 to 10;.
- R.sup.2 is --(CH.sub.2).sub.3 --(OCH.sub.2 CH.sub.2).sub.x --(OCH.sub.2 CH(CH.sub.3)).sub.y --(OCH.sub.2 CH.sub.2).sub.Z --OH
- x, y and z are integers and are independently selected from 0 to 20;
