Abstract

Fluid Foundation formulations typically contain inorganic pigments and a variety of oils in which they are insoluble. These pigments need to be introduced into the formulation in a uniform dispersion to provide the best performance. By incorporation of Bis-octyldodecyl dimer dilinoleate/propanediol copolymer into the oil phase of the formulation, the foundation formulation shows superior spreadability, homogenous distribution of pigments and does not lead to pilling when applied with other cosmetic formulations.

INTRODUCTION

Cosmetics have become an important factor for not only skin health but also mental health. The so called “psychology of cosmetics (1)” appears therefore as a new field and has been related to the beneficial effects of cosmetic practices (2). 

It has been shown that facial cosmetic use can affect all social aspects of life including: body consciousness, social anxiety, and overall body image (3). The typical cosmetic consumers are looking for benefits that go beyond basic makeup (1). These benefits include: multifunctionality (4), natural origin, and ease of use in cosmetics.

The majority of color cosmetics contain colorants. These colorants can either be organic or inorganic. The organic colorants are typically molecules that absorb visible light. These molecules are commonly called “coal tar (5)” because they are derived from coal sources. Organic colorants are synthetic and typically include: indigoids, xanthenes, azos, nitros (8). Inorganic colorants are typically particles of (8): Iron Oxides (CI 77489, CI 77491, CI 77492, CI 77499), Chromium Dioxides, Ult ...
