Definitions

• 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.
• Database GNPD [Online] Mintel November 201 1 (201 1 -1 1 ) "Instant Dry
• XP002683579 Database accession no. 1669958 discloses a dry shampoo comprising aluminium starch octenylsuccinate, silica and glycerine.
• the composition also comprises butylenes glycol.
• “Instant Dry Shampoo” XP002683580 Database accession no. 1727707 discloses a dry shampoo comprising aluminium starch octenylsuccinate, silica and glycerine.
• the composition also comprises butylenes glycol.
• the present invention provides a dry shampoo comprising a base which comprises sebum absorber and propylene glycol, and a propellant.
• the dry shampoo according to the invention provides a cleaning product without leaving white residue on the hair.
• the base comprises from 5 to 20% wt. of the composition.
• the base comprises from 2 to 75% wt of the base sebum absorber.
• 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 starch. A preferred modified starch is aluminum starch octenylsuccinate.
• the dry shampoo comprises an oil which is preferably present at from 0.1 to 5% wt. of the base.
• the oil is isopropyl myristate, benzyl alcohol, PPG-3 benzyl ether myristate. The most preferred is isopropyl myristate.
• the dry shampoo comprises an anti-caking agent which is preferably silica.
• the anti-caking agent is present at from 0.1 to 1 % wt. of the base.
• the propylene glycol is present at from 0.5 to 5% wt. of the base.
• the propylene glycol reduces or prevents white residues being deposited on the hair. This is particularly
• the alcohol is present at from 0.5 to 20% wt. of the composition.
• Suitable alcohols include ethanol.
• composition of the invention also comprises a propellant to suspend the base immediately before mixing and to facilitate its egress from its container.
• composition is stored in a pressurised container.
• Suitable propellants are well known in the art and include butane, isobutene and propane.
• the present invention provides the use of propylene glycol to reduce or prevent white marks in a dry shampoo according to the first aspect.
• Figure shows the test plate used to assess the ability of the test composition to reduce white marks.
• the plate is black and shows that the white marks deposited by Example A is significantly greater than for Example 1 .
• each formulation was sprayed onto a black tile for 3 seconds and the tile is provided in Figure.
• the white marks deposited by the composition comprising butylenes glycol are substantial compared to the same composition comprising propylene glycol.
