AI Technical Summary

Benefits of technology

This patent is about a cosmetic system for making up the lips. It includes two components: a lip basecoat and a topcoat. The basecoat is made with a special silicone film-forming agent, colorant, and a volatile oil, while the topcoat is made with another special silicone film-forming agent, this one in a non-volatile oil. The method involves applying the basecoat first, followed by the topcoat after a waiting period. The topcoat composition is made with a silicone film-forming agent, non-volatile oil, and other cosmetic additives. The technical effect of this patent is to provide a long-lasting, high-quality lipstick that is easy to apply and remove.

Problems solved by technology

Unfortunately, many of these compositions do not generally possess both good long-wear / transfer-resistance properties as well as high gloss.
However, topcoat compositions tend to decrease the long-wear / transfer-resistance properties of the lip compositions, thereby rendering the long-wear / transfer resistant composition less acceptable to consumers and less acceptable for their intended purpose.

Example 1—Invention Compositions

[0136]The following tables set forth a basecoat and topcoat that are consistent with embodiments of the present invention.

Ingredient (% by Weight)BasecoatTopcoatIsododecane50-60Triethylsiloxy silicate15-2515-25Dimethicone, 1000 cSt—75-85Nylon-611 / Dimethicone 5-15PolymerColorants3-8Fillers 6-10Additional Ingredients0-5  0-0.1

Method of Preparing Invention Composition(s)

[0137]The basecoat composition is made by conventional techniques, for example, by: by charging the vessel with optional filler at room temperature and homogenizing, adding pigments (colorants), homogenizing, adding copolymer such as Nylon-611 / Dimethicone Polymer, homogenizing and applying vacuum, adding silicone resin and isododecane at elevated temperature such as 80 C, homogenizing, adding additional fillers, homogenizing, and allowing to cool.

[0138]The topcoat composition is made by charging a vessel with dimethicone, adding vitamin E (additional ingredient) under vortex shear; slowly adding triethylsiloxysilicate, increasing mixing speed and allow to mix while maintaining temperature below 35° C. until Triethylsiloxysilicate is well-dispersed.

ing

[0139]A basecoat and topcoat consistent with Example 1 were tested together as a cosmetic system. One hundred and thirty-four women applied the basecoat and topcoat in a manner consistent with the invention described herein.

[0140]After wearing the cosmetic system, the women were asked whether the product lasted sixteen hours (yes or no). One hundred seven (80%) of the women answered yes. This is surprisingly high, especially for a glossy product.

Abstract

A cosmetic system including a lip basecoat composition that includes at least one first silicone film-forming agent, colorant, and a volatile hydrocarbon oil, and a topcoat composition including at least one second silicone film-forming agent in a non-volatile oil carrier. Methods and topcoats are also provided.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is based upon and claims the benefit of priority from U.S. application Ser. No. 16 / 910,729, filed Jun. 24, 2020, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a topcoat composition for long-wear lip compositions comprising at least one silicone film-forming agent, as well as to cosmetic systems, kits and methods of treating, making-up and enhancing the appearance of lips, including a topcoat composition for application to a basecoat composition.DISCUSSION OF THE BACKGROUND[0003]Many cosmetic compositions, including pigmented cosmetics such as lipsticks or lip colors, have been formulated in an attempt to possess long-wearing properties upon application. Unfortunately, many of these compositions do not generally possess both good long-wear / transfer-resistance properties as well as high gloss.[0004]For example, with respect to lip compos...
