Cosmetic compositions comprising calcium silicates

Abstract

Disclosed is a fluid cosmetic composition comprising a sebum-absorbing calcium silicate. These cosmetic compositions provide effective, long-lasting facial cosmetic coverage that is highly resistant to the sebum-caused deterioration that results in the discoloration and fading typically experienced by conventional cosmetic compositions after a sustained period of use. The cosmetic composition may be in the form of a creme, lotion, gel, semi-solid, dispersion, suspension, foam, mousse or spray.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation of pending U.S. application Ser. No. 10 / 175,464, filed Jun. 19, 2002, the content of which is incorporated herein by reference in its entirety for all purposes.BACKGROUND OF THE INVENTION [0002] Skin is the largest organ of the body, accounting for almost a fifth of the weight of a normal adult. The skin performs the vital function of separating the internal components of the body from the outside environment, while also providing a permeable membrane to protect and maintain the internal organs. [0003] Located throughout the dermal layer of skin, just below its surface, are sebaceous glands, which secrete a material composed primarily of waxes and lipids, known as “sebum”. Sebum acts to moisturize the skin in order to keep it supple and firm, and yet also sufficiently flexible to accommodate the various joints and irregular contours of the body's skeleton and internal organs. Sebum is also believed to provide cert...

AI Technical Summary

Benefits of technology

"The present invention is a cosmetic fluid composition that includes a sebum-absorbing calcium silicate and a dispersant or carrier for the calcium silicate. The invention also includes a method of preparing a cosmetic composition by mixing the calcium silicate with a cyclic silicone to form a premix, which is then combined with other cosmetic ingredients to form the fluid cosmetic composition. The invention also includes a method for treating facial skin by applying the cosmetic composition to the skin. The technical effect of the invention is to provide a cosmetic composition that effectively absorbs sebum and reduces the shine on the skin, while also providing a comfortable and smooth application experience."

Problems solved by technology

While sebum performs these functional skin benefits, it also affects the aesthetic appearance of the skin.

In addition to contributing to the development of skin-blemishing acne, sebum can also compromise the desired facial appearance that women seek to obtain by using cosmetics, especially facial cosmetics.

However, these cosmetics absorb sebum from the skin, causing the facial cosmetic layer to either take on a shine or become darker, giving the skin a spotty, blotched appearance.

In fact, in some cases, an individual's sebum production is so high that it liquefies the cosmetic pigment layer, resulting in a rapid removal of the facial cosmetic either by physical friction and abrasion or by liquid flow.

This problem is particularly acute on the eyelid as well as immediately below the eye.

In order to avoid this it is necessary to frequently remove and reapply the cosmetic layer, which is a considerable inconvenience to most women.
