Abstract

Hair conditioning formulations comprising at least one aminopropyl functional polydimethylsiloxane of formula (I) defined herein wherein R, R1, R2 and R3 independently from each other are CH3, OH or OC1-C4alkyl, x is an integer from 1 to 200, y is an integer from 1 to 500, and the molecular weight of the aminofunctional polysiloxane is from 5000 to 50000 D, and their use for the treatment of keratin-containing fibers, preferably human hair are disclosed.

ABSTRACT

HAIR CONDITIONING COMPOSITIONS

Hair conditioning formulations comprising at least one aminopropyl functional polydimethylsiloxane of formula (I) defined herein

wherein

R, R1, R2 and R3 independently from each other are CH3, OH or OC1-C4alkyl,

x is an integer from 1 to 200,

y is an integer from 1 to 500,

and the molecular weight of the aminofunctional polysiloxane is from 5000 to 50000 D, and their use for the treatment of keratin-containing fibers, preferably human hair are disclosed.

This publication relates to hair care formulations, particularly hair conditioning formulations, comprising at least one aminofunctional polyorganosiloxane. 

It is known to treat fiber materials, in particular flat textile structures with polyorgano­siloxanes.  The fiber materials can be provided with advantageous properties such as, for example a pleasant, soft touch.  Polyorganosiloxanes that contain quaternary groups having a nitrogen atom, and the use of such polyorganosiloxanes for the treatment of textile fiber materials are known as well, for example from DE-A 196 52 524.

It is also known to use aminofunctional polyorganosiloxanes in personal conditioning applications, for example in the treatment of hair.  See for example U.S. Patents 4,563,347, 4,586,518, 4,620,878, 5,132,443 and 6,090,885, the disclosures of which are incorporated by reference in their entirety.

The use of these polysiloxanes still show some disadvantages in view of the stability properties, buildup properties, or the use may interfere with other hair processes such as perming or dyeing.

A hair conditioning formulation, which does not show these disadvantages, has been found.

Suitable hair conditioning formulation comprises

0.05 wt-% to 10 wt%, based on the total weight of the hair conditioning formulation, of at least one aminofunctional polyorganosiloxane of formula (I)

,

wherein

R, R1, R2 and R3 independently from each other are CH3, OH or OC1-C4alkyl,

x is an integer from 1 to 200,

y is an integer from 1 to 500,

and the molecular weight of the aminofunctional polysiloxane is from 5000 to 50000 D.

An especially suitable hair conditioning formulation comprises

0.1 wt-% to 8 wt%, based on the total weight of the hair conditioning formulation, of at least one aminofunctional polyorganosiloxane of formula (I)

, wherein

R, R1, R2 and R3 independently from each other are CH3, OH or OC1-C2alkyl,

x is an integer from 1 to 200,

y is an integer from 1 to 500,

and the molecular weight of the aminofunctional polysiloxane is from 5000 to 40000 D and wherein the ratio of x:y is 1:20 to 1:80.

The polysiloxanes of formula (I) are not known (i.e. concretely disclosed) in U.S. Patent No. 4,586,518 or U.S. Patent No. 4,563,347, but they can be produced by analogy to the processes that can be found therein.  Methods of reducing the amount of volatile components in polysiloxanes are well known to those of ordinary skill in the art.
