Description

Clear leave-on hair care compositions comprising aminosilicones and solvents therefor

Technical Field

The present invention relates to a hair care composition comprising: specific aminosilicones; a solvent for the aminosilicone; wherein the composition is for leave-on use; and wherein the composition has a turbidity of 2.0NTU or less. The compositions of the present invention provide improved dry conditioning benefits such as reduced friction.

Background

Human hair becomes dirty due to contact with the surrounding environment and due to sebum secreted by the scalp. Soiling of the hair can cause it to have a dirty feel and to be unsightly. Soiled hair requires frequent shampooing.

Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless or frizzy condition due to the removal of the natural oils and other natural conditioning and moisturizing components of the hair. Drying can also impart a higher degree of static to the hair, which can interfere with combing and result in a condition commonly referred to as "flyaway hair" or cause an undesirable phenomenon of "split ends". In addition, chemical treatments such as perming, bleaching or coloring can also damage the hair and leave it dry, rough, lusterless and damaged.

Various methods have been developed to condition hair. A common method of providing conditioning benefits to hair is by applying a hair conditioning composition. Conditioning formulations may be in the form of rinse-off products or leave-on products, and may be in the form of emulsions, creams, gels, sprays, mousses, oils, liquids, and creams.

For leave-on products, especially those in liquid form (e.g., oils, liquids, and creams), silicone oils such as dimethylpolysiloxanes and/or aminosilicones are commonly used. However, there remains a need for such products that provide improved dry conditioning benefits, such as reduced friction.

In addition, there is a need for leave-on products that provide reduced sticky/greasy feel while providing such conditioning benefits, such as reduced friction.

Furthermore, there is a need for leave-on products, especially those in liquid form, having a uniform transparent product appearance, as such appearance is considered a signal of reduced sticky/greasy feel.

None of the prior art provides all of the advantages and benefits of the present invention.

The content of components that are substantially insoluble in the composition of the present invention is preferably controlled in terms of uniform transparent product appearance. By "substantially insoluble" compounds is meant:

the compound is substantially insoluble in the composition in the amount used; and is

When included in the amounts used, the compositions: (i) non-uniformity due to, for example, phase separation; or (ii) uniform but with a higher turbidity, i.e. a turbidity at 25 ℃ higher than 2.0NTU (excluding 2.0 NTU), preferably higher than 1.5NTU (excluding 1.5 NTU), more preferably higher than 1.0NTU (excluding 1.0 NTU), still more preferably higher than 0.7NTU (excluding 0.7 NTU).

It has been surprisingly found that higher levels of nitrogen (amine functional groups) in the aminosilicone tend to result in less friction reduction and therefore lower conditioning benefits from the aminosilicone.

Aminosilicones for use herein are those corresponding to the general formula (I):

(R₁)_aG_3-a-Si-(-OSiG₂)_n-(-OSiG_b(R₁)_2-b)_m-O-SiG_3-a(R₁)_a

Such preferred aminosiloxanes may be referred to as terminal aminosiloxanes, since one or both ends of the siloxane chain are terminated by a nitrogen-containing group. It has also been surprisingly found that such terminal aminosilicones provide improved friction reduction compared to grafted aminosilicones.

Commercially available isoparaffins can have their degree of polymerization distribution and can be, for example, mixtures of trimers, tetramers, pentamers, and hexamers. Herein, tetramer means commercially available isoparaffin in which tetramer has the highest content, i.e., tetramer content is preferably 70% or more, more preferably 80% or more, still more preferably 85% or more.

For such isoparaffins, especially when using pentamers, hexamers and higher polymers of isobutylene, they may be used in combination with ethanol in order to provide reduced tackiness/greasiness.
