Abstract: This invention relates to a hair care composition more particularly to a wash-off composition, especially preferred being a shampoo or a conditioner, which provides the desired anti-dandruff efficacy with enhanced stability of the active materials on hair/scalp during use. This is achieved through a judicious combination of an organic UV filter, a zinc compound and selective anti-dandruff agent. The composition comprises 0.01 to 3% by weight zinc pyrithione, an organic UV filter and 0.1 to 5% by weight additional zinc compound. The weight ratio of zinc compound to zinc pyrithione is over 3:1.

Abstract: This invention relates to an antimicrobial composition, especially one which provides synergistic anti-dandruff efficacy. This is achieved through a judicious combination of anti-dandruff agent zinc pyrithione and an alcoholic compound of specific types. These compositions can be delivered through very many different types of personal care products e.g. shampoo or conditioner.

Abstract: This invention relates to an antimicrobial cleansing composition, especially one which provides synergistic anti-dandruff efficacy. This is achieved through a judicious combination of anti-dandruff agent zinc pyrithione and thymol in a composition comprising synthetic anionic surfactant.

Abstract: This invention relates to a hair care composition more particularly to a wash-off composition, especially preferred being a shampoo or a conditioner, which provides the desired anti-dandruff efficacy with enhanced stability of the active materials on hair/scalp during use. Disclosed is a hair care composition comprising: (i) 0.01 to 3% by weight zinc pyrithione; (ii) 1 to 5% by weight amino acid; and (iii) 0.1 to 5% by weight additional zinc compound.

Abstract: A cooling system for a gas turbine engine (FIG. 1) comprises a pre-swirl arrangement, preferably including a pre-swirl chamber, for providing cooling air to a turbine blade disc, and a ventilation arrangement for providing ventilation air to a rotating component of the gas turbine engine. The cooling system includes an air bypass arrangement, which preferably includes first, second and third air bypass duct portions, for conveying ventilation air away from the pre-swirl arrangement.

Abstract: A retaining arrangement for joining together two components such as a rim coverplate 10 and a rotor disc 12 in a gas turbine engine. The arrangement comprising a channel 54 formed by respective formations 26, 52 on the disc 12 and coverplate 10, which channel 54 locates one or more annular ring member 66 which prevents relative axial movement therebetween. Engageable abutment formations 18, 46 are provided respectively on the disc 12 and coverplate 10, to prevent relative pivotal movement.

Abstract: A gas turbine engine rotor disc (20) is provided with a plurality of cooling air supply passages (32) which are generally radially extending but are inclined in the downstream direction. Each passage (32) has a cross-sectional configuration which renders the ends (34) of the passages (32) less likely than normal to act as the site of hoop-stress induced cracks.
