技术领域
本发明属于增稠技术领域,具体涉及一种高分子增稠剂及其制备方法与应用。
背景技术
在化妆品、药品行业,高分子增稠剂一般用于乳膏与精华等剂型中,起着增稠、悬浮等作用。合成的高分子增稠剂有油溶性和水溶性两大类,如果没有特别说明,本发明专指的是水溶性高分子增稠剂(以下简称高分子增稠剂)。
化妆品和药品用的高分子增稠剂中,最常用的是卡波姆。此外,还有Seppic公司的Simugel系列聚合物(如Simugel EG)以及丙烯酰胺共聚物Sepigel 305、汉生胶、刺槐豆胶,不常用的有泊洛沙姆407、泊洛沙姆184等。
近几年,伴随着相关法规的推出,以及消费者对化妆品、医药品功效要求的进一步提高,对于酸性体系化妆品、医药品的市场容量越来越大,各大网络平台上果酸类、水杨酸类、壬二酸类化妆品的搜索量直线上升。但是,常用的高分子增稠剂体系中加入酸性物质后,会导致体系崩溃(稠度急剧下降,或者冷热稳定性不好);或者因添加量太大,比如泊洛沙姆需要添加10wt%以上,导致气味很大,肤感也不好,成本很高;例如添加了20wt%壬二酸的配方,常温或者低温下存储一定时间后会有大量壬二酸晶体析出;添加了2~5wt%水杨酸的配方,存在变色或者稳定性差等问题。
