[0189] Preparation of random terpolymers

[0190] Component (b) Random terpolymers of formula (I) can be prepared in a conventional manner, for example, by bulk or solution polymerization. In view of the controllability of the polymerization reaction and the viscosity of the final product, polymerization in a solvent is preferred. Suitable solvents are dimethylsulfoxide, THF, DMF, ethyl, propyl, butyl, acetate, benzene, toluene, xylene, n-butanol, isobutanol, isopropanol, MEK, MIBK, acetone ,wait.

[0191] The monomers are preferably polymerized using free radical reactions by adding peroxides, optionally in the presence of redox systems.

[0192] The polymerization time of the random terpolymer of component (b) formula (I) depends on the temperature and the desired properties of the final product, but is preferably in the range of from about 50°C to about 190°C within from 0.5 to 10 hours Inside. The polymerization reaction may be carried out continuously, discontinuous...

Embodiment 1

[0257] Example 1 - Random Terpolymer

[0258] In a reaction flask with a reflux condenser suitable for polymerization, dissolve 9.86 g xylene and 4.93 g methoxypropyl acetate, 2.84 g vinyltoluene, 4.55 g isobutyl methacrylate, 7.36 g 2- Ethylhexyl ester, 5.20 g 2-hydroxyethyl methacrylate, 1.80 g polyethylene glycol monomethacrylate having a molecular weight of about 400, and 0.44 g di-tert-butyl peroxide. At the boiling point of the mixture, an inert gas is introduced, and the polymerization reaction is carried out while stirring. At the end of the polymerization, 9.79 g of isophorone diisocyanate was dissolved in 16.58 g of isobutyl acetate and 16.58 g of methoxypropyl acetate, and then mixed with 3.60 g of polyethylene glycol monomethyl acetate having a molecular weight of about 400 Acrylate and 4.51 g of 1-(3-aminopropyl)imidazole were used to convert the remaining free NCO groups.

[0259] The solids content was then adjusted to 40% by weight with butyl acetate.

Embodiment 2

[0261] Example 2 - Random Terpolymer

[0262] In a similar manner to Example 1, 3.54 g of vinyl toluene, 5.69 g of isobornyl methacrylate, 9.20 g of 2-ethylhexyl methacrylate, 7.15 g of hydroxyethyl methacrylate, and 1.28 g di-t-butyl peroxide was dissolved in 11.94 g xylene and 5.97 g methoxypropyl acetate and polymerized.

[0263] Subsequently, 12.23 g of isophorone diisocyanate were dissolved in 20.36 g of butyl acetate and 20.36 g of methoxypropyl acetate, and added. The remaining free NCO groups were then neutralized with 4.50 g of polyethylene glycol monomethacrylate having a molecular weight of approximately 400 and 3.78 g of 3-amino-1,2,4-triazole in 11.34 g of N-methylpyrrolidone. The group is transformed.

[0264] The solids content was then adjusted to 40% by weight with butyl acetate.

[0265] According to structural formula (I), component M is vinyltoluene, and y is 7.7% by weight, relative to the total weight of the terpolymer; Component T is a mixture of is...

Abstract

The present invention relates to topically applicable, water-resistant cosmetic or dermatological compositions well suited for the cosmetic color compositions for human skin and / or hair comprising at least one (a) coloring agent; (b) at least one random terpolymer; and, optionally (c) other cosmetically acceptable ingredients.

Description

[0001] This application claims the benefit of US Provisional Application No. 61 / 194,877, filed October 1, 2008. field of invention [0002] Pigmented cosmetic compositions containing random terpolymers which impart long-term adhesion to the skin, high resistance to water penetration and resistance to smearing, staining and transfer properties of the composition Coloring cosmetics are given. Furthermore, pigment cosmetic compositions containing said terpolymers provide pigments with high dispersion properties, which in turn give a smoother and evenly applied color film on the skin and hair. The coloring composition includes the cosmetic products such as foundation, lipstick, lip gloss, mascara, eyeliner, eyeshadow and the like. Background of the invention [0003] Colored cosmetic compositions, such as foundations, blush, lipstick, mascara, eyeliner, eye shadow, are used to color the skin and lips. Since coloring is one of the most important reasons for using cosmetics, cos...
