Properties of Eggshell as a Raw Material of Cosmetics

Abstract

The calcium lactate products, obtained by reaction of lactic acid with ground eggshell particles, contains finely divided protein films. The films obtained from 75, 225μm eggshell particles fitted well to the liquid phase, and were quite suitable as scrub (friction) particles.
On the other hand, the products with the particles less than 10 μm formed emulsions suitable for night cream marterials.
The lactate prod uct containing smaller protein films showed more effcient adsorption property. These results indicate that the eggshell is a good raw material for a cosmetic cream.
