标题:某些基于乳酸的阴离子表面活性剂的合成及表面和生物学性质的评估
摘要:在本研究中,合成了11种基于乳酸的阴离子表面活性剂,并对其表面和生物学活性进行了评估.合成涉及乳酸与一系列链长以及支链和不饱和度不同的脂肪醇的酯化反应.通过用氯磺酸处理将所得的酯磺化,然后用naoh水溶液形成盐.使用表面张力测定法测定所有合成的表面活性剂的表面性质.合成的表面活性剂显示出较低的临界胶束浓度(cmc)值,并且随着烷基链长度的增加而呈下降趋势.与具有相同碳原子数的线性对应物相比,烷基支化还导致cmc值的轻微变化,尽管观测到这种减少或增加取决于分支的位置和数量.一些合成的表面活性剂对被测微生物菌株和细胞系表现出非常好的抗微生物和抗癌活性.

摘要:A subject of the present invention is the cosmetic use of a pericarp extract of the plant Nephelium lappaceum for maintaining and/or increasing the hydration and/or the barrier effect of the skin and/or of the mucous membranes. The pericarp extract increases involucrin synthesis and the hyaluronic acid content and the synthesis of ATP and of the taurine transporter TAUT. Another subject of the invention relates to a cosmetic care process comprising the topical application of the pericarp extract of N. lappaceum. Finally, a subject of the invention relates to the pericarp extract for use, in particular dermatological use, thereof in the treatment and/or prevention of pathological conditions caused by a state of abnormal dryness of the skin and/or of the mucous membranes.
