AI Technical Summary

Problems solved by technology

However, when using conventional waxes such as beeswax, candelilla or carnauba wax at such high levels, the mascara composition can reach a very thick consistency and even become too dense for easy application with conventional mascaras. Brush applicator to apply to lashes
This overly thick mascara deposits on the eyelashes in clumps, so that the obtained make-up effect does not have the desired smooth look; the make-up result is uneven and does not look beautiful
[0009] Furthermore, the use of certain waxes such as orange wax or lanolin wax at levels above 25% by weight resulted in compositions that were not stable enough, especially after two weeks of storage at room temperature (25° C.): the composition coagulated into Solid state (greatly increased viscosity) or phase separation visible to the naked eye
Therefore the composition is not suitable for eyelashes

Embodiment 2 to 6

[0194] -Wax 27g

[0195] -Bentonite 5.3g

[0196] -Propylene carbonate 1.7g

[0197] -Vinyl Acetate / Allyl Stearate Copolymer

[0198] (65 / 35) (Mexomer PQ from Chimex) 2.2g

[0199] -Polyvinyllaurate (from Chimex Mexomer PP) 0.7g

[0200] -Silica 0.8g

[0201] -Pigment 3.6g

[0202] -Preservative

[0203] -Isododecane appropriate amount to 100g

[0204] For each composition, its viscosity and consistency index were measured, and its stability was evaluated at 25°C.

[0205] The viscosity measurement was carried out at 25°C with a Rheomat RM 180 viscometer equipped with a No. 4 spindle. -1 The shear rate was rotated for 10 minutes (after which time the viscosity and the rotor rotation speed were observed to stabilize).

[0206] The consistency index was measured with a TA-XT2i texture analyzer from Rheo Company equipped with a stainless steel cylindrical probe with a diameter of 12 mm.

[0207] The mascara composition to be tested was filled into a cylindrical container (35 mm in di...

Embodiment 7

[0215] Prepare a wax-in-water emulsion mascara with the following composition:

[0216] -Adhesive wax (from Koster Keunen company

[0217] Koster K 82 P) 30g

[0218] -2-Amino-2-methyl-1,3-propanediol 0.5g

[0219] -Triethanolamine 2.4g

[0220] -Stearic acid 5.8g

[0221] -Water-soluble non-ionic polymer 4.3g

[0222] -Sodium polymethacrylate (Darvan 7 from Vandetbilt) 0.25gAM

[0223] -Hydroxyethyl cellulose cross-linked with epichlorohydrin quaternized with trimethylamine

[0224] (JR 400 available from Union Carbide) 0.1g

[0225] -Pigment 5.4g

[0226] -Preservative

[0227] -Water appropriate amount to 100g

[0228] This mascara is stable after 24 hours of storage at room temperature. It is easy to apply and adheres well to eyelashes. The mascara forms a smooth, even makeup and thickens the eyelashes.

Embodiment 8

[0230] Prepare an anhydrous mascara with the following composition:

[0231] -Adhesive wax (from Koster Keunen company

[0232] Koster K 82 P) 30g

[0233] -Bentonite 5.3g

[0234] -Propylene carbonate 1.7g

[0235] -Vinyl Acetate / Allyl Stearate Copolymer (65 / 35)

[0236] (MexomerPQ from Chimex) 2.2g

[0237] -Polyvinyl laurate (Mexomer PP from Chimex) 0.7g

[0238] Stearic acid ester of oligomer of -12-hydroxy-stearic acid

[0239] (Solsperse 21000 from Avecia) 0.1g

[0240] -Silica 0.8g

[0241] -Pigment 4.2g

[0242] -Preservative

[0243] -Isododecane appropriate amount to 100g

[0244] This waterproof mascara can adhere well to the eyelashes. It makes the eyelashes get a smooth and even makeup with good separation.

Abstract

Cosmetic composition comprising a wax with an adhesion greater or equal to 0.7 N.s and a hardness less than or equal to 3.5 MPa, and a filler of surface area BET greater or equal to 100 m2 / g. Independent claims are also included for the application and use of the composition.

Description

Technical field [0001] The subject of the present invention is a cosmetic composition for coating keratin fibers, which contains an adhesive wax. The present invention also relates to a cosmetic product for makeup or treatment of keratin fibers such as eyelashes, eyebrows and hair. [0002] Another subject of the present invention is a composition for the care or makeup of the eyes, such as eyeliner or eyeshadow. [0003] The composition of the present invention may be a cosmetic composition, also known as mascara, a cosmetic base for keratin fibers, or an underlayer, a composition applied to makeup, also known as top coat Oil, or a composition for treating keratin fibers. The composition of the present invention is more specifically a mascara. Background technique [0004] The term "mascara" should be understood to refer to a composition applied to the eyelashes: it can be a cosmetic composition for eyelashes, a cosmetic base for eyelashes, and a composition applied to mascara T...
