Abstract

Make-up compositions of high aesthetic value can be created by using products made with surface treatment and impact milling. These products are hydrophobized cosmetic colorants. The coating consists of isopropyl triisostearoyl titanate and a branched ethoxy dimethicone. Starting from our patent application US 20080014233, the amount of coating was increased, and the particle size made finer from the previous examples shown. The ensuing products have lower oil absorption values, improved dispersibility in different carriers, and may be readily incorporated into a wide range of color cosmetic applications without the need of high sheer processing like roller mills and bead mills.

DESCRIPTION

Background of the Invention

Field of the Work

The products of the present work may find use in formulations for the face, eyes, lips, cheeks, nails, and also the body. In the USA, the term color additive (colorant) is being used by the FDA, the agency responsible for regulating cosmetic ingredients, to describe any dye, pigment or substance which when added or applied to a food, drug or cosmetic, or to the human body, is capable (alone or through reactions with other substances) of imparting color.  They are typically disclosed by companies in the cosmetic product ingredient listing. Colorants include metal oxide pigments such as titanium dioxide, iron oxides, zinc oxide, and other inorganic pigments like ultramarine pigments, including ultramarine blue, ultramarine pink, and ultramarine violet, and organic pigments listed in 21CRF  PART 74- listing of color additives subject to certification, for example, D&C Red 6 , D&C Red 7,  D&C Red 22, D&C Red 27, D&C Red 28, D&C Red 30, D&C Red 33, D&C Red 36,  D&C Red 40, FD&C Yellow 5, FD&C Yellow 6, D&C Yellow 10, FD&C Blue 1, D&C Black 2 and their corresponding lakes.

The cosmetic chemists of today are facing new challenges, as a result of changing demographics, changes in social norms, and the influence of social media. The task to beautify the population is complex. The population continues to age, has become increasingly more diverse in skin tones because of interracial marriages, and has become more demanding and knowledgeable as a result of access to electronic media. Improvements in colorants have become necessary. Women communicate through their make-up color. Today, there are millions of consumers of all ages using cell phones to take photos and for them the posting of digitized images on social media is a necessity. The quality of video captured on HDTV and computers continues to advance. Pigments must be surface treated and milled for high color purity in order to create shades with the appropriate level of lightness, darkness, chroma and hue. Likewise, pigments must be coated and milled in order to optimize gloss, in addition to chroma and hue.

The pigments to be coated can be of different morphologies, for example, iron oxides could be spherical, acicular,...
