Embodiment 1

[0534]

[0535] Method steps: disperse thickener, glutamate surfactant and colorant in water phase by stirring. Phase A then forms upon heating to 90°C. Phase A was then poured into lipid phase B containing wax and glucoside surfactant at 90°C. Emulsify by stirring with a Moritz mixer.

[0536] The emulsion was then cooled to 60°C under rotor / stator agitation and then cooled to 25°C with slow agitation using flat blades.

[0537] The resulting wax-in-water emulsion had a pH of 6.7, which was measured the day after preparation after stirring at 200 rpm for 10 minutes at 25°C using a Rheomat 180 instrument from Lamy equipped with an MS-R4 spindle. The viscosity of the emulsion is 5.4 Pa.s.

Embodiment 2

[0539]

[0540] Add phase C, consisting of sorbic acid and ethanol, to the mixture of phases A and B.

[0541] The composition was prepared according to the method of Example 1. Following the protocol described in Example 1, the viscosity of the composition was determined the next day to be 7.6 Pa.s.

Embodiment 3

[0543]

[0544] Compositions were prepared according to the methods of Examples 1 and 2. Following the protocol described in Example 1, the viscosity of the composition was determined the next day to be 8.3 Pa.s.

Abstract

The present invention relates to a composition for coating keratin fibres, more particularly the eyelashes, characterized in that it is present in the form of a wax-in-water emulsion comprising a combination of at least one glutamic acid derivative and/or salt thereof and at least one alkylpolyglycoside.

Description

technical field [0001] The present invention provides a cosmetic composition for coating keratin fibers, in particular eyelashes, in the form of a wax-in-water emulsion and containing at least one glutamic acid derivative and / or a salt thereof and at least one alkyl polyglycoside. [0002] The composition of the invention may be a composition for making up or caring for keratinous fibers such as eyelashes, eyebrows and hair. More particularly, the composition is a keratin fiber cosmetic composition. [0003] More specifically, the composition of the present invention is a composition specially applied to the eyelashes, which composition is also called "mascara". The composition may be a cosmetic composition, a cosmetic primer composition, or a topcoat composition applied on top of a cosmetic primer composition. The mascara is more specifically dedicated to human eyelashes, but can also be used for false eyelashes. Background technique [0004] In particular, known mascar...
