标题:Composition comprising a rice protein hydrolysate and an agent for increasing glycosaminoglycan synthesis
发明人：GUILLOU VERONIQUE; THIRY ANNABELLE
权利人:OREAL
摘要:The present invention relates to a process for preventing and/or reducing the signs of ageing of the skin, in particular for remodelling the face and/or limiting the age-related hollowing of the face, by applying to facial skin a composition containing, in a physiologically acceptable medium, at least one rice protein hydrolysate and at least one agent for increasing glycosaminoglycan synthesis.

权利人:BEIERSDORF AG
摘要:The invention relates to agents that are to be applied to the skin or hair and contain compounds for intensifying tanning of the skin and increasing melanin synthesis in skin or hair. The invention particularly relates to cosmetic or dermatological preparations. Using said preparations results in inducing and intensifying the tanning mechanisms of the skin, intensifying the hair color, and thus also increasing intrinsic protection of the skin or hair.

摘要:The invention relates to agents for use on skin or hair, particularly for increasing skin tanning and the synthesis of melanin in skin or hair. The invention contains, in particular, cosmetic or dermatological preparations containing quadruply substituted cyclohexene compounds. The use of the preparations leads to the induction and intensification of the tanning mechanisms of skin, the intensification of hair color and thus also to an intensification of the skin's and hair's intrinsic protection.

摘要:Processes for the synthesis of phthalides and fluorans are disclosed. New isolatable intermediate phthalides have been found which serve as precursors to the production of fluorans. The products of this invention are synthesized from keto acids and phenolic amines, wherein the mole ratio of the keto acids to the phenolic amines is in excess of 1:1. Not only is product yield greatly improved, but usual condensation times of 24 hours and longer have been reduced to about 5 hours.

摘要:##STR1## Compounds of formulae (I), (II) wherein X is an optionally substituted benzyl group which carries an NO 2 group in the ortho-position, Z is a group of formula α or β, R, R' and Y are each optionally substituted groups, R' is hydrogen or alkyl, m and n are each integers of from 1 to 6, and q is an integer of from 1 to 20, and salts thereof. These protected or caged organic compounds, based on the dyes fluorescein (I) and rhodamine (II), can be introduced into biological systems and there released by means of light radiation. They are suitable, for example, for use in the labelling of proteins or lipophilic structures. Processes for the preparation of the compounds are also described.
