Field of the Invention
The present invention relates to powder-based cosmetic compositions having improved performance characteristics. More specifically, the present invention is concerned with powder-based cosmetic compositions having a high affinity for keratinous surfaces which demonstrate improved transfer-resistance, long-wear, good coverage and oil-controlling properties. Moreover, the compositions feel silky and comfortable on the skin.
Description of the Prior Art
Women continually seek cosmetic products for application to skin, such as makeup foundation, pressed powder, blush and eyes shadow, that maintain their fresh look for extended periods of time and which exhibit transfer resistance. Powder-based cosmetics are well known. They are typically provided in solid form and comprise a major portion of powdered material, such as fillers and pigments, together with a binder, if the product is intended to be pressed into a container. Nevertheless, many such products tend to lack substantivity with the skin, and therefore are easily transferred to surfaces and must be reapplied frequently to main a fresh look. A major disadvantage with powder-based cosmetics which purport to provide long wear is that the extended wear is typically achieved by using solvents, waxes and/or polymers which adversely affect the feel of the product on the skin. Moreover, such ingredients can be irritating to skin. A further disadvantage of some known powder-based cosmetics is that they are composed substantially of talc. Talc is used as an absorbent, an opacifier, and to improve the feel of a product. Nevertheless, as an absorbent, talc not only soaks up oil, but, over time, also steals moisture from the product, causing it to lose its luxurious feel. Some products include silicon forming resins which can flake off. To address that problem, silicon-forming resins have been combined with plasticizers, but the resulting film may feel tacky on the skin.
There therefore remains a need for powder-based cosmetics which require fewer applications by consumers and have the attributes of a silky feel, long wear, transfer-resistance, resistance to streaking, longer lasting color and oil absorption, particularly under high humidity conditions.
