Description

Process for the manufacture of color cosmetic compositions containing wax blends

The present invention relates to a method for forming anhydrous, moldable cosmetic compositions comprising a blend of waxes.

In recent years, there has been a strong trend towards the use of silicone fluids in cosmetic compositions. The main reason for their popularity is the elegance that silicones provide: products containing them smooth the skin with excellent glide without the greasy feeling that non-silicone oils often leave. Silicone oils are now a common component of almost all types of cosmetic compositions (both liquid and powder), such as foundations, concealers, eyeshadows and eyeliners, lipsticks and lip pencils, and blushers.

Another attractive aspect of silicone oils is their tendency to create a very shiny appearance on the skin to which they are applied. For certain types of cosmetics, especially those aimed at younger consumers for whom a bright or glossy look is very attractive, or for cosmetics intended for evening use ( where soft light allows A greater range of shine produced by cosmetics), which is often desirable.

However, for certain types of cosmetic products, and/or for certain types of consumers, large amounts of gloss are not required, and may not even be appropriate. More mature users may not be satisfied with very shiny or shiny makeup. The fine lines and wrinkles that characterize more mature skin are accentuated by glossy products that tend to reflect light directly. Better for consumers of a certain age is a cosmetic that diffuses or diffuses light, providing a "soft focus" that blurs lines and hides pigmentation. Attempts to achieve this type of masking in the past have relied primarily on the use of higher levels of pigment, but this has often resulted in a heavy, caked product which is not satisfactory to most consumers.

Similarly, it may only be necessary to remove gloss from products used in certain environments. For example, glossy cosmetics are often viewed as inappropriate in a conservative office setting, and/or may be too glaring in the harsh light of a typical office. In these environments, a more matte finish may be desired for cosmetic products. Traditionally, this has been achieved by adding solid powders such as mica, silica, talc, etc. to the formulation. In the case of silicone oil based compositions, however, attenuating the resulting shine tends to be more difficult than with traditional cosmetic oils, thus requiring the addition of even greater amounts of solid fillers. However, the larger proportion of solids in the formulation results in a heavy drag sensation on the skin, negating to some extent some of the benefits of silicone oils. Alternatively, a more matte appearance can be achieved by including one or more volatile components in the formulation, such as water or volatile oils; this generally increases the concentration of pigment relative to the composition as the volatiles evaporate after application , resulting in a more matte appearance. However, this can also lead to a dry, cakey appearance on the skin. also, The use of volatiles, especially water, is inappropriate and/or infeasible in all products (such as anhydrous lipstick products) and also leads to the need to find specialized (and often expensive) airtight packaging to prevent volatiles from Product loss in packaging.

In light of the above, there remains a need for cosmetic compositions that deliver excellent payoff and aesthetics without the disadvantage of the unpleasant feel exhibited by existing formulations when high levels of solids are included.

The present invention relates to a method for forming anhydrous, moldable cosmetic compositions. According to the method, four cosmetic waxes are combined in a vessel to form the first phase. The solvent and wetting agent are combined in a separate vessel to form the second phase. Then, the first and second phases are combined to form a cosmetic composition. Cosmetic compositions with a high pigment load combined with excellent sensory and payoff characteristics.

The cosmetic composition can be in the form of eye shadow, blush, face powder, lipstick and the like.

This and other aspects of the invention are described below.
