Fine-tuning the morphology of self-assembled nanostructures of propargyl ammonium-based amphiphiles

N-Methyl-N-(pentacosa-10,12-diyn)-propargylamine organizes itself into an unusual supramolecular pH- and thermo-responsive system. Studies have showed that submillimetric length hollow laths form this unique structure in the presence of hydrochloric acid. Specific chemical modifications on the initial molecule and small-angle neutron scattering experiments were performed to understand the structure of this system. Our results allow us to suggest a possible structure of the laths.

Pterocarpan, phenol and lipid constituents from Butea monosperma stem

In addition to stigmasterol-3-αL-arabinopyranoside, four new compounds isolated from the stems of Butea monosperma have been characterized as 3-methoxy-8, 9-methylenedioxypterocarp-6-ene, 21-methylene-22-hydroxy-24-oxooctacosanoic acid methyl ester, 4-pentacosanylphenol and pentacosanyl-β D-glucopyranoside by spectral data and chemical studies.

Hair growth composition containing citric acid esters

Triesters of citric acid are used for inducing, maintaining or increasing hair growth. Compositions for topical application to mammalian hair or scalp comprise an effective amount of from 1% to 99% by weight of an ester of citric acid having the structure (1): where, R1, R2 and R3 each independently represent a branched or unbranched alkyl, alkenyl, aryl, alkylaryl or arylalkyl group, each said group having from 1 to 18 carbon atoms, R4 represents -H, or a branched or unbranched saturated or unsaturated acyl, alkyl, aryl, alkylaryl or aylalkyl group having from 1 to 18 carbon atoms, in the presence of a cosmetically acceptable vehicle for the citric acid ester and in the absence of solid absorbent for the ester;, said effective amount of said ester being sufficient to increase hair growth in the rat, when said composition is applied topically thereto over a period of no more than three months, by at least 10% more than that obtainable using a control composition from which the said ester has been omitted, in accordance with the Rat Hair Growth Test.
