Abstract

Dry shampoo comprising a base which comprises from 0.1 to 30% wt. starch or derivative thereof, and a propellant.

Description

COMPOSITION
The present invention relates to a dry shampoo. Dry Shampoos are compositions for cleansing the hair without washing with water. The product provides a suitable product to provide a clean feel and look on days when perhaps there is no opportunity, either through lack of time or lack of available water, to wash the hair. Despite the prior art there remains a need for improved dry shampoos.
Dry shampoo comprising a base which comprises from 0.1 to 30% wt. of the base sebum absorber, a polyol and a propellant. The dry shampoo according to the invention provides a cleaning product without leaving white residue on the hair.
Preferably, the base comprises from 5 to 20% wt. of the composition. Preferably the base comprises from 2 to 75% wt. of the base sebum absorber.
Preferably, the sebum absorber is a starch or derivative thereof. More preferably, the sebum absorber is selected from corn starch, tapioca starch, rice starch, and modified corn starch. A preferred modified starch is aluminum starch
octenylsuccinate.
Preferably, the dry shampoo comprises an oil which is preferably present from 0.1 to 5% wt. of the base. Preferably, the oil is isopropyl myristate, benzyl alcohol, PPG-3 Benzyl ether myristate.
Preferably, the dry shampoo comprises an anti-caking agent which is preferably silica. Preferably the anti-caking agent is present at from 0.1 to 1 % wt. of the base.
Preferably, the polyol comprises from 3 to 12 carbons, more preferably from 2 to 8 carbons.
More preferably, the polyol is a glycol.
Preferably, the polyol is selected from propylene glycol and butylene glycol. Preferably, the polyol is present at from 0.5 to 5% wt. of the base.
In a composition according to the invention the polyol prevents or reduces the white residues. Preferably, the alcohol is present at from 0.5 to 20% wt. of the composition. Suitable alcohols include ethanol.
Preferably the composition according to the invention also comprises alcohol for solubilising sebum and so cleansing the hair.
The composition of the invention also comprises a propellant to suspend the base immediately before mixing and to facilitate its egress from its container.
The composition will be stored in a pressurised container.
Suitable propellants are well known in the art and include butane, isobutene and propane. EXAMPLES
The products described in the table were applied to a black tile for analysis of the white residue.
Figure imgf000004_0001
Formulation A deposited significant white residue onto the tile. Formulation B also deposited significant white residue onto the tile though not as much as A.
Inventive formulation 1 deposited significantly less onto the tile despite having a third the level of starch as B. The degree of whiteness on the tile was markedly lower than would have been expected should the relationship between starch content and residue be linear.
It was surprisingly concluded that there is a threshold of starch level below which there is a much reduced degree of residue deposited.
