权利人:DOUCET OLIVIER; PUJOS MURIEL; ROBERT CÉCILE; BERNINI DOROTHÉE; COTY GERMANY GMBH
摘要:The invention refers to a cosmetic composition for increasing collagen synthesis in skin cells comprising 0.001-0.5 wt % of a Phaeodactylum tricornutum extract, 0.00001-2.0 wt % of Dimer Tripeptide-43 or Hydrolyzed Rice Protein, and cosmetic auxiliaries. The cosmetic composition comprising the combination of both components has an synergistic effect on collagen I synthesis in skin cells and has a booster effect to other substances which are known to have an enhancing effect to collagen I synthesis.

标题:Compositions and methods of synthesizing arachidin-3 from resveratrol

权利人:PARNATIVE INC; PARNATIVE INC
摘要:Composition, methods of synthesizing trans-arachidin-3; and, methods of use as a dietary supplement, food additive, pharmaceutical, nutraceutical, cosmeceutical, and antioxidant. The methods of production entail organic syntheses using primary alkylamines or primary hydroxyalkyl amines, or carboxy amines (amino acids) with natural carboxylic acids (acetic acid) as catalysts to react isovaleraldehye with trans-resveratrol. The synthesis is carried out in organic solvent, which is composed of an azeotropic mixture comprising toluene with pyridine, n-butanol, n-propanol, 2-propanol, 2-methyl-1-propanol, or other alcohols that form an azeotrope with toluene. The final product is purified and analyzed for the amount of trans-arachidin-3, such as via HPLC, IR, column chromatography, and high-performance counter-current chromatography. All solvent and catalysts used in the reaction are approved by the FDA as either food additives, secondary direct food additives, and/or indirect food additives, and thus this synthetic trans-arachidin-3 may be used in the food and cosmetic industry.

摘要:The invention relates in particular to the cosmetic use (i) of at least one agent for promoting the production of NO in and/or on the lips, chosen from nitric oxide NO donors or precursors; nonpolymeric NO releasers; and NO synthase synthesis and/or activity stimulators; or (ii) of other agents for promoting microcirculation in the skin, chosen from potassium channel openers; calcium channel blockers; phosphodiesterase inhibitors; flavonoids; vasodilator peptides that are not NO donors; temperature modulators; agents for promoting the stimulation and/or maintenance of angiogenesis; agents for promoting the stimulation of endothelial cell proliferation; agents for promoting endothelial cell migration; and mixtures thereof, in a makeup and/or care composition for the lips, as an agent for naturally making the lips full again and/or naturally coloring the lips. It also relates to specific care and/or makeup compositions for the lips containing said agent, and also to a cosmetic process aimed at making the lips naturally full and/or colored, using said compositions .

标 题:Methods for preparing prenyl alcohol
发明人：BABLER JAMES H
权利人:UNIV LOYOLA CHICAGO
摘要:Methods for preparing 3-methyl-2-buten-1-ol (prenyl alcohol) from 2-methyl-1,3-butadiene (isoprene) and carboxylic acids are disclosed. Carboxylic acids which can be used in the process have a K a (relative to water) greater than 10 -4 ; dichloroacetic acid is especially preferred. The process involves the slow (e.g., dropwise) addition of isoprene to the carboxylic acid to form a prenyl ester. The ester-formation reaction proceeds at room temperature in most cases; use of an organic base catalyst, preferably a sodium or potassium salt of the reactant carboxylic acid, improves the yield. The resultant prenyl ester can be converted to prenyl alcohol by reaction with a base. Prenyl alcohol can be readily converted to citral, a chemical intermediate in the synthesis of vitamins A and E, and several widely-used carotenoids.
