the reaction of the Grignard reagent from benzyl chloride with aldehydes has been obtained from a study of the interaction of the Grignard reagent from 1-phenylethyl chloride with carbonyl compounds. This Grignard reagent reacts with ketones (except non-enolisable ketones) to give normal alcohols in low yields, and with aldehydes to give diols. However, in contrast to that formed in the reaction of
A composition such as a water-based consumer product comprises material (e.g. perfume) encapsulated within shell capsules, each capsule comprising an encapsulating wall having an inner surface and an outer surface, with a coating on the inner surface and/or outer surface of the shell wall, the composition further comprising surfactant and/or solvent. The coating can improve the barrier properties of the shell and can enhance retention of the encapsulated materials within the shell.

The present invention has an object to provide an external dermal composition for anti-ageing, which prevents or improves apparent skin problems such as wrinkles, fine wrinkles, blemishes, and saggings caused by increasing age or ageing; and maintains or improves the barrier function and the hyaluronic acid production in the skin. The object is solved by providing an external dermal composition for anti-ageing, which contains an aqueous medium as a base material and one or more ingredients selected from L-ascorbic acid, derivatives thereof, and their salts as an effective ingredient(s).
