摘要:The present invention provides a method for synthesizing a zederone analogue derived from natural materials, a precursor useful in synthesis of the zederone analogue, and an intermediate useful for synthesizing the zederone precursor. Specifically, the present invention uses (E) -5-halegeno-4-hexanoic acid alkyl ester as a starting material to synthesize a zederone analogue, a precursor useful in synthesis of the zederone analogue, and an intermediate useful for synthesizing the zederone precursor.

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 .
