The present invention concerns enhancements in the cooling effects of certain physiological coolant-containing compositions such as topically applied cosmetic, toiletry or pharmaceutical products, wherein the cooling effect of the physiological coolants is enhanced by the addition of a substance according to formula (I) or dermatologically acceptable salts thereof:R&#x2014;CR(OR)&#x2014;CO&#x2014;NR&#x2014;CRR&#x2014;X&#x2014;OR&#x2003;&#x2003;(I)It was found that substances represented by formula (I) are capable of bringing about greater cooling effects from reduced concentrations of physiological coolants without behaving as physiological coolants themselves, thereby enabling the preparation of compositions that do not necessarily have the characteristic minty odor of menthol-containing products and/or to allow greater freedom in creating perfumed products.

Compositions comprising a physiological coolant

A non-oxidative hair coloring composition, comprises yogurt or yogurt-derived material. The invention also provides a method of improving the coloring effects of non-oxidative hair coloring compositions, comprising application to the hair (during or after dyeing) of yogurt or a yogurt-derived material. The invention also covers use of yogurt or yogurt-derived material in a hair care composition for the purpose of improving the coloring effects of a non-oxidative hair dye. The invention can be put into effect by incorporating yogurt or yogurt-derived material into a hair care composition for use during non-oxidative dying of hair (i.e. a non-oxidative hair coloring composition) where it acts to improve dye deposition onto hair, or into a composition for use on hair after dyeing by a non-oxidative method, e.g. a shampoo or conditioner composition, to help maintain the color of dyed hair.

Non-oxidative hair coloring using yogurt

A composition suitable for use on the skin or hair comprising: a) at least one extract of a Boswellia plant or at least one boswellic acid; and b) a carrier selected from the group consisting of branched fatty alcohols containing 8 to 32 carbon atoms, branched fatty acids containing 8 to 32 carbon atoms, unsaturated fatty alcohols containing 12 to 24 carbon atoms, unsaturated fatty acids containing 12 to 24 carbon atoms and derivatives of said branched fatty alcohols, said branched fatty acids, said unsaturated fatty alcohols and said unsaturated fatty acids, or mixtures thereof.

Compositions containing Boswellia extracts

The use of menthyl 2-pyrrolidone-5-carboxylate as an insect repellent, usually by application to a substrate or into an air space. The menthyl 2-pyrrolidone-5-arboxylate can be used as a composition, which may be perfumed. A useful composition comprises a mixture of menthyl 2-pyrrolidone-5-arboxylate and a known insect repellent or a compound shown to be an effective insect repellent on a test described herein.
