Abstract
A novel use of two specific neopentyl glycol diesters as wetting, dispersing, spreading and deterging agents for micronized TiO.sub.2, ZnO and other pigments is introduced. These esters, neopentyl glycol di-2-ethyl hexanoate and neopentyl glycol di-isostearate, are used in varying combinations and may also be used with an emulsifying agent for a water dispersible pigmented make-up cleaner composition.
Claims6
A method of wetting, dispersing, spreading and deterging micronized pigments comprising:
- neopentyl glycol di-isostearate and neopentyl glycol di-2-ethyl hexanoate as the esters which are the wetting, dispersing, spreading and deterging compounds;
- said esters varying in weight/weight ratio from 90.% neopentyl glycol di-isostearate, 10% neopentyl di-2-ethyl hexanoate to 10% neopentyl d-2-ethyl hexanoate/90% neopentyl glycol di-isostearate and a micronized pigment selected from a group consisting of ZnO and TiO.sub.2.
