A hydroxyethyl cellulose dispersion was prepared in the remaining 30% of the water and heated to 75°C under low shear. The cellulose dispersion was then added to the initial mixture under low shear, followed by addition of the oil (tricaprylin). 5 minutes of high shear under vacuum was then undertaken. The resultant mixture was slowly cooled with low shear mixing. Silicone fluid and phenoxy ethanol were then added. Triethanolamine was added r followed by perfume and then high shear mixing under vacuum was conducted. The Examples were applied to hair switches and the styling performance was assessed. For this purpose 0.5g of hair cream was applied to a straight, flat, 2.5 cm wide, 25 cm long hair switch weighing 5g. The cream was spread through the hair and subsequently the hair was pressed together to create a volume down effect. After styling the frontal area of each switch was assessed by image analysis. Performance was benchmarked against a current commercial hair cream material {referred to as benchmark). The following results were obtained: WO 2005/025525 PCT/EP2004/009609 Material no.
