Problems solved by technology

The drawback of these polymers is having a high molecular weight poly(alkylene glycol) based center block which gives the polymer a high degree of crystallinity leading to opaque and / or greasy properties

preparation Embodiment 1

[0619] 75 ml of methyl ethyl ketone (MEK) was put into a reactor (four-necked flask) equipped with two addition funnels, a condenser and a mechanical stirrer, and heated to 80°C.

[0620] Meanwhile, a solution comprising monomer: 50 g of polyethylene glycol methacrylate (MPEG 550), 50 g of dimethylaminopropyl methacrylamide (DMAPMA) and initiator: 0.5 g of (Trigonox 21S) was prepared 1. Solution 2 was also prepared, comprising 75 ml of methyl ethyl ketone and 0.5 g of initiator (Trigonox 21S).

[0621] Solution 1 was dropped into the four-necked flask reactor over 1 hour, and Solution 2 was dropped over 2 hours. The resulting mixture was then kept at 80°C for 5 hours. The obtained orange-yellow solution was cooled. 95 g of polymer are obtained.

[0622] The polymer has a Brookfield viscosity of 7.5 mPa.s as measured at 25°C in a 15% solution of the polymer in MEK using a No. 1 needle mandrel at a speed of 0.1 rpm.

[0623] The polymer can then be neutralized as follows: 2...

preparation Embodiment 2

[0627] 100 ml of water was put into a reactor (four-necked flask) equipped with two addition funnels, a condenser and a mechanical stirrer, and heated to 80°C.

[0628] Simultaneously, solution 1 was prepared comprising 50 g of monomeric MPEG 550, 1 g of initiator (potassium persulfate KPS) and 50 ml of water.

[0629] Solution 2 comprising 50 g of monomeric DMAPMA 100% neutralized with betaine hydrochloride and 50 g of water was also prepared.

[0630] Solutions 1 and 2 were dropped into a four-necked flask over 1 hour. After 1 hour at 80°C, a mixture of 1 g of KPS in 50 ml of water was added dropwise over 15 minutes.

[0631] The resulting mixture was then kept at 80°C for 3 hours. 90 g of polymer neutralized with betaine hydrochloride are obtained.

[0632] The polymer has a Brookfield viscosity of 164 mPa.s, measured at 25°C in a 15% aqueous solution of the polymer at a speed of 6 rpm using a No. 1 needle mandrel.

[0633] The polymer is soluble in water (up to at leas...

Abstract

The invention concerns cosmetic compositions comprising: A) at least one conditioning agent selected among synthetic oils, mineral oils, vegetable oils, fluorinated and perfluorinated oils, natural or synthetic waxes, silicones, cationic polymers whereof the cationic filler density is less than 5 meq / g, cationic proteins, cationic protein hydrolysates, ceramide type compounds, cationic surfactants, fatty amines, fatty acids and their derivatives, as well as mixtures of those various compounds, and B) at least one ethylene copolymer comprising, in weight percentage based on the total weight of the polymer: a) 10-60 wt. % of one or more monomers of formula (I) as defined below; b) 40-90 wt. % of a substantially cationic monomer selected among (i) one or more cationic monomers of formula (IIa); (ii) one or more amphoteric monomers of formulae (IIc) and (IId); and (iii) a mixture of one or more cationic monomers of formula (IIa) with one or more anionic monomers selected among maleic anhydride and / or those of formula (IIb); and / or with one or more amphoteric monomers selected among those of formulae (IIc) and (IId), c) an optionally 0-50 wt. % of nonionic hydrophilic monomers, excluding methyl acrylate, methyl methacrylate and isopropyl acrylate when they are present in an amount not less than 10 wt. %. Hair treated with said compositions are more easily disentangled during rinsing, and exhibits softness after drying. The inventive compositions also allow particularly interesting hair brushing after drying.

Description

technical field [0001] The present invention relates to compositions comprising at least one conditioning agent and at least one olefin copolymer having a polyethylene glycol graft. Background technique [0002] It is known practice to use polymers in cosmetics, especially in hair care products of the leave-on type, for example to obtain hair hold and hold properties. [0003] In the field of "rinse-off" compositions, such as shampoos or hair conditioners, water-soluble synthetic cationic polymers are also used, which are known to provide good cosmetic properties to the hair; however, these polymers do not provide hair styling effect. The same is true for cationic polymers of natural origin, such as modified guar gums, which also provide cosmetic properties but not molding. In the field of rinse-off compositions, polymers do not provide sufficient styling properties in relation to acceptable cosmetic properties. [0004] It is an object of the present invention to provide...
