Aerosol foam for hair treatment

The invention relates to an aerosol foam for hair treatment containing at least one cationic, amphoteric or zwitterionic polymer, at least one surfactant, at least one defoamer, an aqueous or aqueous-alcoholic solvent system and at least one aerosol propellant. The defoamer is preferably a silicone antifoam emulsion which contains physiologically indifferent active components based on polydimethylsiloxane / silica.

Aerosol foams for hair treatment are known and generally consist of hair-setting or hair-care substances, foaming agents and propellant gases and a suitable water-based solvent base. Various demands are placed on the quality of such aerosol foams, which can be roughly divided into two groups. One group of quality requirements relates to the quality of the foam, ie the nature of the foam. These include, for example, the fine or coarse pores, the compactness, the temporal stability of the foam, the incorporability and distributability on the hair, etc. The second group of quality requirements relates to the effects that the foam has on the hair after incorporation into the hair , ie the hair care properties such as, for example, the handle of the hair when wet and dry, the combability, the strengthening, the stress on the hair, etc. The problem with the optimization of aerosol foams is that although the addition of special active ingredients can improve some quality requirements, for example the foam quality, this is bought with a deterioration in other quality requirements, for example the hair-care properties. The object was therefore to improve the foam quality of aerosol foams for hair treatment, the hair care properties not being impaired at the same time, but ideally also being improved.

It has now been found that the incorporation of a good lathering and hair-care base into the hair is facilitated if defoamers are added to the base, which promote rapid breakdown of the foam on the hair. At the same time, the hair care properties of the base are not deteriorated, but are even further improved, especially when using defoamers based on polydimethylsiloxane / silica.

The subject of the invention is therefore an aerosol foam for hair treatment containing

(A) at least one cationic, amphoteric or zwitterionic polymer,

(B) at least one surfactant,

(C) at least one defoamer, (D) an aqueous or an aqueous-alcoholic solvent system and (E) at least one aerosol propellant. Polymer (A)

The cosmetic agent according to the invention is applied by applying and incorporating it in an amount sufficient to achieve the desired hair-care or hair-fixing effect on damp, towel-dried hair and leaving it in the hair without rinsing. Then the hairstyle can be shaped in the usual way or the hair can be inserted and finally blow-dried. But it is also possible to use the product directly on dry hair.

By adding a defoamer based on poly-dimethylsiloxane / silica (Simethicone) to aerosol hair foam formulations, a foam that breaks down very quickly on the hair can be obtained. The care properties are not impaired by the very small amount used (for example 0.01-0.5% by weight) but even improved, especially the wet grip, the combability, the dry grip and the strain on dry hair.

The following examples are intended to explain the subject matter of the invention in more detail.
