Embodiment 1

[0115] A carnauba wax microdispersion was prepared with the following composition:

[0116] -Carnauba Wax 27g

[0117] -Polyoxyethylated (30 EO) Glyceryl Monostearate 6.75g

[0118] (Tagat S from Goldschmidt)

[0119] -Ethanol 10g

[0120] - Water appropriate amount 100g

[0121] Heat the wax and surfactant to 90°C while homogenizing the mixture with moderate agitation. Water heated to 90°C was then added with continuous stirring. The mixture was cooled to room temperature and ethanol was added to produce a wax microdispersion with an average particle size of approximately 170 nm. Example 2 :

Embodiment 2

[0122] Prepare a mascara with the following composition:

[0123] -Polyurethane aqueous dispersion, under the name of Goodrich company 14g active substance

[0124] Avalure UR 425 sales, 49% (weight) live

[0125] Sexual substance

[0126] - Wax microdispersion of Example 1 31.5 g

[0127] - Beeswax 10g

[0128] -Thickener 1.9g

[0129] -Ethanol 7g

[0130] -Propylene glycol 5g

[0131] -Pigment 5g

[0132] - Appropriate amount of preservatives

[0133] - Water appropriate amount 100g

[0134]The mascara is prepared by mixing polyurethane and thickener in an aqueous dispersion and heating the mixture to 65°C. Next, the beeswax was melted and then dispersed into the thickened latex with stirring to form beeswax particles with an average particle size greater than 1 μm. The mixture was then cooled to room temperature (approximately 25° C.) and the base pigment and wax microdispersion in propylene glycol, and preservative dissolved in ethanol were added.

Embodiment 3

[0136] Prepare a mascara with the following composition:

[0137] -Polyurethane aqueous dispersion, under the name of Goodrich company 16g active substance

[0138] Avalure UR 425 sales, 49% (weight) live

[0139] Sexual substance

[0140] -Micro 31.5g of a mixture of acrylic copolymer wax and mineral wax

[0141] Dispersion (wax 20% by weight) from Byk Cera

[0142] Marketed under the name "Aquacer 520"

[0143] -Cantery Wax 15g

[0144] -Thickener 1.9g

[0145] -Ethanol 7g

[0146] -Propylene glycol 5g

[0147] -Pigment 5g

[0148] - Appropriate amount of preservatives

[0149] - Water appropriate amount 100g

[0150] The mascara is easy to apply on the eyelashes and creates a heavy makeup that is water-resistant to cold water (20°C). And can make the eyelashes curl well.

Abstract

The invention concerns a composition comprising, in a physiologically acceptable medium containing an aqueous phase,: an aqueous dispersion of film-forming particles, an aqueous micro-dispersion of particles of a first wax having a melting point not less than 70 DEG C, the particles of the first wax having an average size less than 1 mu m, and an aqueous dispersion of particles having a melting point less than 70 DEG C, the particles of the second wax having an average size not less than 1 mu m. The composition provides a make-up resistant to cold water. It also provides the eyelashes good curved shape. The invention is applicable to make-up and care of keratinous matter, in particular mascara.

Description

technical field [0001] The present invention relates to a cosmetic composition comprising a film-forming polymer and a wax, said composition being used for the cosmetic or cosmetic care of keratinous substances such as keratinous fibers such as eyelashes, Eyebrows or hair, but also substances such as skin and nails, especially in humans. The invention also relates to a cosmetic care and make-up method for keratin substances. [0002] The composition may be in the form of a mascara, eyeliner, lipstick, face powder, eye shadow, foundation, body make-up, concealer, nail product, sunscreen composition, skin coloring composition or skin care product. The present invention more particularly relates to mascaras. [0003] The term "mascara" means a composition for the eyelashes: it may be a cosmetic composition for the eyelashes, a cosmetic base for the eyelashes, a composition applied over mascara, also called a top coat, or a cosmetic treatment for the eyelashes Compositions.
