Problems solved by technology

However, pressed powders also cannot incorporate shear-sensitive ingredients due to the shear force required to mix the powder and solvent mixture
In addition, the evaporation process is lengthy and the use of specific solvents (e.g., water) may promote unfavorable microbial growth

Embodiment I

[0067] eye shadow

[0068] Exemplary powder eyeshadow compositions of the present invention having an interconnected base and cosmetic powder and having a multimodal distribution of particles are provided in Table 2.

[0069] Table 2

[0070]

[0071]

[0072] The powdered cosmetic compositions of Table 2 were prepared by mixing fillers, pigments (including pearlescent agents), binders, and preservatives to form a cosmetic powder premix. A wet premix was prepared by mixing a portion of the wet adhesive with the wax at a temperature of 85°C. Mix the cosmetic powder premix with the wet premix. Spray the wet premix over the powdered premix, mixing the two ingredients together. The mixture is then processed using a hammer mill. After this, the pearlescent agent and the remainder of the wet binder are added and mixed into a mixture.

[0073] The mixture was then gently pressed into a three-dimensional mold and heated in a convection oven at a temperature of 80°C for abou...

Embodiment II

[0075] eye shadow

[0076] Another eyeshadow composition of the present invention is provided in Table 3 having an interconnected matrix and a cosmetic powder with a multimodal particle distribution. Eye shadows can be made using the same method as described in Example 1 above.

[0078]

[0079]

Embodiment III

[0081] The spreadability of powdered cosmetic compositions made according to the invention was compared as a function of wax loading with that of conventionally pressed powdered cosmetics. Samples were prepared according to Formulations A-E by heating to a temperature sufficient to melt the wax or pressing the product in the absence of heat. The wax content ranged from 5% to 20% by weight, as shown in Table 4.

[0082] Table 4

[0083]

[0084] Smear effect test method

[0085] This method can be used to determine the spreadability or transferability of powder cosmetics. This test predicts the ability of the cosmetic composition to transfer to the applicator or finger during normal use of the cosmetic. The spreadability of the product is directly proportional to the amount of makeup removed by the applied shear force. Thus, the smudge effect can be expressed as a function of the amount of makeup lost after the rub test described herein.

Abstract

Methods for preparing a solid powder cosmetic composition comprise heating a wax component and one or more cosmetic powders at a temperature sufficient to melt the wax, and subsequently cooling the mixture to provide a solid composition comprising a wax matrix having particulate materials homogenously dispersed therein.

Description

field of invention [0001] The present invention generally relates to powdered cosmetic compositions. More particularly, the present invention relates to powdered cosmetic compositions formed by heating a mixture of wax and powder to melt the wax and subsequently resolidifying the wax. Background of the invention [0002] Conventional powder cosmetics are usually in the form of pressed powders. The compaction of powders needs to provide sufficient physical cohesion so that powder cosmetics can be in the portable compact form desired by consumers. Pressed powders, however, tend to have a fragile structure because they generally do not incorporate continuous structural components and are therefore poorly self-sustaining. In particular, conventional powdered cosmetics (ie, pressed powders) are brittle, tend to flake off and / or crumble, and tend to crumble or crack upon impact. For example, conventional products are likely to shatter or crack when dropped by a consumer, render...
