Problems solved by technology

In addition, certain film-forming polymers such as hydroxyethylcellulose or hydroxypropyl chitosan can form a white film on the eyelashes after drying, resulting in an unsightly cosmetic effect
Therefore, such polymers are not suitable for use in transparent mascara

Embodiment 1

[0094] Prepare clear mascara with the following composition:

[0095]- Vinylpyrrolidone / acrylic acid / lauryl methacrylate terpolymer, sold under the name Acrylidone LM(R) by ISP 2.6 g

[0096] - Polyvinylpyrrolidone / vinyl acetate copolymer in ethanol at 50% by weight, sold under the name Luviskol VA 73 E by the company BASF 3.5 gAM

[0097] - Carboxy vinyl polymer (purchased from 3VSA's Synthalen K) 0.6g

[0098] —Aminomethylpropanol 0.65g

[0099] —Triethanolamine 0.6g

[0100] - Dimethicone copolyol (Q2 5220 from Dow Coming) 1 g

[0101] — preservatives qs

[0102] —Water qs 100g

[0103] This mascara comes in the form of a clear gel for easy styling of lashes. After drying, it forms a clear coat on the lashes and provides good curling of the lashes.

Embodiment 2

[0105] A mascara was prepared with the following composition:

[0106] —Carnauba Wax 4.7g

[0107] —Rice bran wax 2.2g

[0108] - Paraffin 2.2g

[0109] —Beeswax 8.2g

[0110] —Talc 1g

[0111] —Bentonite 5g

[0112] —Vinyl acetate / allyl stearate copolymer (65 / 35) 6.7g

[0113] - polyvinyl laurate (Mexomer PP from Chimex) 0.7 g

[0114] —Isododecane 52.8g

[0115] - Propylene carbonate 1.6g

[0116] - Vinylpyrrolidone / acrylic acid / lauryl methacrylate terpolymer, sold under the name Acrylidone LM(R) by ISP 0.58 g

[0117] —Aminomethylpropanol 0.14g

[0118] —Pigment 4.9g

[0119] — preservatives qs

[0120] —Water qs 100g

[0121] A waterproof mascara is produced which is easy to apply evenly on the lashes and provides good curling of the lashes.

Embodiment 3

[0123] (a) Preparation of a carnauba wax microdispersion having the following composition:

[0124] —Carnauba Wax 30g

[0125] - polyoxyethylenated (30EO) glycerol monostearate (Tagat S from Goldschmidt) 7.5 g

[0126] —Preservative 0.3g

[0127] —Water qs 100g

[0128] The wax, surfactant and preservative were heated to 95°C with moderate stirring to homogenize the compound. Water, which had been heated to 95°C, was then added with constant stirring. The mixture was cooled to room temperature to produce a wax microdispersion with an average particle size of about 285 nm.

[0129] (b) preparing a mascara having the following composition:

[0130] - Wax microdispersion prepared in (a) 5 g

[0131] - Vinylpyrrolidone / acrylic acid / lauryl methacrylate terpolymer, sold under the name Acrylidone LM(R) by ISP 2.6 g

[0132] - Polyvinylpyrrolidone / vinyl acetate copolymer in ethanol at 50% by weight, sold under the name Luviskol VA 73 E by the company BASF 3.5 gAM

[0133] - Ca...

Abstract

A transparent or translucent mascara composition for curving eyelashes, comprises a vinyl lactam film forming polymer, an ethylenically unsaturated carboxylic acid and optionally a hydrophobic monomer. The invention also relate to methods of coating the mascaras which can curve eyelashes nicely and forming a transparent coating.

Description

technical field [0001] The present invention relates to the use of a vinyllactam polymer-containing mascara for curling eyelashes. The present invention also relates to a composition for transparent or translucent eyelashes containing the polymer. This use and the composition of the present invention are particularly suitable for human eyelashes or false eyelashes. The term "mascara" refers to a cosmetic composition for eyelashes, a cosmetic base, a product applied over a cosmetic layer (also known as a top coat), or an eyelash cosmetic care product. Background technique [0002] Mascaras typically contain film-forming polymers to apply a film to the eyelashes as they are applied. Mascaras of this type are described in particular in documents WO 91 / 1273, EP-A-530084 and WO 95 / 15741. Users are looking for mascara that visibly curls lashes. However, not all film-forming polymers achieve satisfactory eyelash curling. In addition, certain film-forming polymers such as hydro...
