  聚（甲基丙烯酸烷基酯）的伽马辐照

  摘要：

  一系列聚（甲基丙烯酸烷基酯）由高纯度单体制备并经受伽马辐射。对于聚（甲基丙烯酸正庚酯），在 15 Mreps 下检测到正烷基系列中的凝胶化；随着烷基长度的增加，在较低剂量下检测到凝胶。聚（甲基丙烯酸仲烷基酯）照射到较高剂量时未发现凝胶化；聚（甲基丙烯酸仲壬酯）在 40 Mreps 辐照后仍可溶解。讨论了与早期聚（丙烯酸烷基酯）辐照工作的相关性。

  A repeat insult microbial test method in which an antimicrobial agent is applied to a porous permeable substrate. The porous permeable substrate is inoculated with microorganisms and the porous permeable substrate is incubated for a predetermined period of time, at a temperature which is conducive to the flourishment of the microorganisms. The porous permeable substrate is reinoculated and reincubated a predetermined plurality of times and the inoculated porous permeable substrate is incubated for a final period of time between 18-24 hours at the temperature used previously. The porous permeable substrate is then examined and the growth of microorganisms is determined.

  A method of enhancing the deposition of a silicone conditioner to hair is disclosed. The silicone conditioner is delivered to the hair in an aqueous shampoo and is a polydimethylsiloxane fluid entrapped in a nontoxic hydrophobic macroporous highly crosslinked polymer. The macroporous polymer is a mixture of particulates including unit particles having an average diameter of less than one micrometer; agglomerates formed of fused unit particles and having an average diameter of twenty to eighty micrometers; and aggregates formed of clusters of fused agglomerates and having an average diameter of two-hundred to twelve-hundred micrometers.

• Adsorption of sweat components with a macroporous copolymer

  A method of preventing underarm malodor associated with human perspiration. There is applied to the skin of a human, a safe and effective amount of a macroporous crosslinked copolymer containing acrylate or methacrylate units. Components of sweat such as fatty acids found in human perspiration, are adsorbed and entrapped into and within the confines of the macroporous copolymer. The macroporous copolymer possesses a pore diameter of a size sufficiently small to inhibit skin bacteria from entering. Decomposition of fatty acid and sweat components by the skin bacteria is thereby retarded, and hence the generation of body malodor is reduced. The macroporous copolymer may be applied to the human skin in the form of a deodorant stick, a deodorant cream, a deodorant lotion, a deodorant spray, a deodorant roll-on, a deodorant pad, a pressed powder deodorant, a loose powder deodorant or a deodorant gel.

  一种防止与人体汗液有关的腋下恶臭的方法。在人体皮肤上涂抹安全有效量的含有丙烯酸酯或甲基丙烯酸酯单元的大孔交联共聚物。汗液中的成分，如人体汗液中的脂肪酸，会被吸附并包裹在大孔共聚物中。大孔共聚物的孔径小到足以抑制皮肤细菌进入。这样，皮肤细菌对脂肪酸和汗液成分的分解就会被延缓，从而减少体臭的产生。大孔共聚物可以除臭棒、除臭膏、除臭乳液、除臭喷雾、除臭滚珠、除臭垫、压粉除臭剂、散粉除臭剂或除臭凝胶的形式涂抹在人体皮肤上。
