Abstract

Description

"Sprayable hair conditioner"

The invention is in the field of cosmetic agents and relates to transparent, sprayable hair conditioning compositions containing amines, cationic surfactants and cationic polymers. The invention further relates to the use of the hair conditioner for improving the hair care and a cosmetic method for hair care using the hair conditioner.

Not least due to the heavy use of hair, for example by dyeing or perming, cleaning with shampoos and environmental pollution, the importance of care products with the longest possible effect is steadily increasing.

The reason for this is that the hair can be damaged by the treatment / stress both externally and in its structure, which gives them an unattractive appearance, which is characterized by lack of smoothness and softness, lack of shine, but also by a poor combability, Hair breakage or split ends can be noticeable.

It is therefore customary to subject the hair to a special post-treatment in order to supply them with care substances which give them back a beautiful outward appearance and strengthen the hair structure, as well as to care for the scalp or to prevent it from drying out. In such post-treatments, the hair is treated with special active ingredients, for example quaternary ammonium salts or special polymers, usually in the form of a rinse. Depending on the formulation, this treatment can improve the combability, the hold, the fullness and the shine of the hair.

The incorporation of skin and hair conditioners in a cosmetically suitable - usually aqueous - basis, but the manufacturers of such compositions but always in great difficulty.

In particular, in the preparation of transparent formulations, which are preferred by consumers, a stable incorporation of skin and hair conditioning agents in hair care products and the storage of these agents over a longer period has not always been satisfactory.

Especially with temperature fluctuations stability problems could often be observed.

Therefore, there is still a need for aesthetically-pleasing hair conditioners that increase combing, elasticity, shine and volume of the hair.

By "aesthetically pleasing hair conditioners" is meant transparent formulations.

Furthermore, there is a need for hair conditioning agents that are easy to handle. Therefore, a transparent hair conditioner based on a specific combination of active substances that can be sprayed is proposed.

The subject of the present invention is therefore a transparent sprayable

Hair conditioner containing

a) at least one compound of the formula (I)

R ¹

rf-, (i)

R ²

in which the radicals R and R ² independently of one another are H or a lower alkyl group having 1 to 4 C atoms, and the radical R ^{3 is} the group R ⁴ -CO (NH) - (CH ₂ ) _n -, in which R ⁴ denotes a saturated or unsaturated, branched or unbranched alkyl chain having 7 to 21 C atoms, and n denotes an integer from 1 to 4,

b) at least one compound of the formula (II)

R ⁵

R ⁸ -NR ⁶ X ^" (II)

I,

R ⁷

in which at most three of the radicals R ⁵ to R ^{8 are} independently of one another an alkyl group having 1 to 4 C atoms, at least one radical R ⁵ to R ^{8 is} a saturated or unsaturated, branched or unbranched alkyl chain having 8 to 30 C atoms and X ^"represents a halide or a methosulfate group, and

c) at least one quaternized hydroxyethylcellulose polymer, the cationic

Trimethylammonium- and dimethyldodecylammonium groups as substituents.

A suitable cosmetic carrier for the hair conditioning agents according to the invention is preferably aqueous and / or aqueous / alcoholic. It preferably contains at least 50% by weight of water. For the purposes of the present invention, aqueous-alcoholic cosmetic carriers include aqueous solutions containing 3 to 70% by weight of a C ₁ -C ₆ -alcohol, in particular methanol, ethanol or propanol, isopropanol, butanol, isobutanol, tert-butanol, n-pentanol , iso-pentanols, n-hexanol, iso-hexanols, glycol, glycerol, 1, 2-pentanediol, 1, 5-pentanediol, 1, 2-hexanediol or 1, 6-hexanediol to understand. The compositions of the invention may additionally contain other organic solvents, such as methoxybutanol, benzyl alcohol, ethyl diglycol or 1, 2-propylene glycol. In a particularly preferred embodiment, the hair conditioning agents contain - based on their total weight - at least 70 wt .-%, preferably at least 80 wt .-%, more preferably at least 85 wt .-% and in particular at least 90 wt .-% of an aqueous or aqueous alcoholic carrier.
