Whitening skin care productSkin-whitening cosmetic containing algae active extracts

The invention discloses a skin-whitening cosmetica whitening skin care product containing algae active extracts. The skin-whitening cosmetics iswhitening skin care product is prepared from the following raw materials in percentage by mass: 2 to 5 percent of hyaluronic acid, 0.5 to 1 percent of lecithin, 4 to 8 percent of glycerol, 1 to 5 percent of cetostearyl alcohol, 1 to 5.5 percent of glycerylstearate, 0.5 to 3 percent of polydimethylsiloxane, 0.5 to 1.5 percent of algal active extracts, 0.2 to 0.8 percent of whitening and anti-blackening agents, 2 to 6 percent of natural whitening grease, 0.5 to 1 percent of VC, 0.5 to 1 percent of VE, 0.1 to 0.35 percent of pH regulators, 1 to 5 percent of propanediol and the balance of deionized water. The raw material ingredients are scientifically proportioned; the activity of tyrosinase is inhibited internally in an inner aspect; the problem of melanin generation is fundamentally solved; in an outer aspectexternally, the active free radicalsare cleared through irideae extracts; the immunologic function of the skin is improved, so that the durable and continuous skin whitening effects can be achieved.

CONDENSATIONS BIOMIMETIQUES: EDIFICATION DE SQUELETTES TERPENIQUES A PARTIR DE SYNTHONS ISOPRENIQUES

The action of perchloric, trifluoroacetic and formic acids on the 1,1-(and 3,3-) dimethylallylic alcohols has been studied.In the presence of formic acid in dichloromethane 2-methyl-3-butene-2-ol (DMVC) has been condensed on the acetate of 3-methyl-3-butene-1-ol (IPA) giving geranylic and lavandulylic type 1,1-adducts.Saponification, dehydration, oxidation and isomerisation of the former type lead to citral.In the same medium, DMVC produces (after saponification) a C10 glycol which upon dehydration produces lavandulol in a convenient way.Geraniol and its acetate have been condensed with low yield on IPA giving farnesylic derivatives.
