Cosmetic Pigments

Currently, besides catering to the pharmaceutical industry, Luid energy milling is employed for size reduction of agricultural chemicals, carbon black, ceramics, cosmetics, pigments, precious metals, propellants, resins, and toner materials.

When colour cosmetic pigments are added to O/W or W/O emulsions, the resulting system is referred to as a suspoemulsion. The particles can be in either the internal or external phases, or both, as illustrated in Figure 11.12. An understanding of competitive interactions is also important when optimising the formulation stability and performance of these materials.

Atomic spectrometry has been used to determine metallic components in toothpaste, sunscreen, shampoos, cosmetic pigments, etc. Elements can be found in cosmetics and toiletries as active ingredients (e.g., Se in shampoos) or as impurities from the raw materials. The elements most frequently determined are Pb, Hg, and As but Se, Cd, Zn, Ti, Fe, Cr, Si Bi, Ba,...

Amino-chromenes represent an important class of compounds being the main components of many naturally occurring products. They can be utilized as cosmetics, pigments widely [91], and potential biodegradable agrochemicals [92]. These compounds have been of interest to the medicinal chemist for many years. Hj pSlaPjWjQO, J was used successfully as an efficient catalyst in the reaction of aldehydes, malononitrile, and a- and P-naphthol for the synthesis of 4 and 5 (Scheme 3.33). 

Huq et al. (2001) have tentatively identified goyazite in Punic cosmetic pigments using synchrotron radiation X-ray diffraction (SR-XRD) techniques. 

So-called molybdate orange and molybdate red qq-v.) pigments are produced by the addition of a small amount of lead molybdate, PbMo04 (and occasionally some lead sulfate) to a lead chromate pigment. These typically contain 15% molybdate and 5% sulfate. The mineral analogue, wulfenite q.v. has been found among cosmetic pigments from Ur (Bimson, 1980).
