AI Technical Summary

Benefits of technology

This patent is about a special eye makeup oil-in-water emulsion that can be used alone or with other eye makeup products like shadow and mascara. It contains talc and high HLB surfactants to create a smooth, easy to apply formula that can be used on both the eyelid and eyelashes. It also includes optional ingredients like silicone and glycerin, as well as a secondary filler agent and can be colorant-free. The emulsion can be applied directly to the eyelids and eyelashes, and then the eyeshadow or mascara can be applied on top for a complete eye makeup look.

Problems solved by technology

But these products tend to be difficult to remove.
Emulsion products with talc have been used as eyeshadow primers, but the amount of talc in the products is low, for both aesthetic and performance reasons.

example

[0113]The present invention will be described in a more detailed manner by way of examples. However, these examples should not be construed as limiting the scope of the present invention. The examples below are presented as non-limiting illustrations in the field of the invention.

[0114]Preparations

[0115]The following compositions according to Example 1 (Ex. 1) and Comparative Example 2 (Comp. Ex 2), shown in Table 1, were prepared by mixing the components shown in Table 1. Specifically, the Phase A ingredients were added to a first vessel and heated to 65C / 75C while being mixed until homogenous, then set aside. The Phase B ingredients were then added to a new vessel and heated to 65C / 75C and being mixed until homogenous. Phase A is then added to Phase B, and emulsified. The composition is then cooled to 45C / 50C and Phase C was added with strong homogenization with rotor stator at 2500 rpm for at least 15 min. The composition was then further cooled to 25C / 30C and Phase D was added w...

Abstract

Cosmetic compositions, and methods of use, where the cosmetic compositions are multi-purpose oil-in-water emulsions that contain (i) a surfactant system of high HLB surfactants and (ii) a high load of talc. The emulsions are capable of being used as a base for eye cosmetics, in order to enhance wear of eyeshadow and removal of mascara.

Description

TECHNICAL FIELD[0001]The present invention relates to cosmetic compositions, and specifically to cosmetic compositions containing a high HLB surfactants and a high load of talc that are capable of being used as a base for other eye cosmetics, in order to enhance wear of eyeshadow and removal of mascara.BACKGROUND[0002]Consumers of eye cosmetics desire products that provide long wear for the eye cosmetics, and allow those eye cosmetics to be removed easily, in addition to providing an aesthetic finish. As these are typically competing interests, consumers who wish good wear and easy removal may be required to purchase additional products to meet those needs—for example, a long-lasting mascara may need to purchase a special product to remove the eye cosmetic from the lashes. Given that eye cosmetics include eyeliners, eyeshadows, and mascaras, the proliferation of products that a consumer may require can quickly grow beyond a desirable quantity. Thus, a product that can reduce the num...
