Clear antiperspirant and/or deodorant compositions, especially clear sticks having good structural integrity, can be formed by incorporating at least 8% by weight based on the total weight of the composition of a selected siliconized polyamide into a product formulated with at least one silicone material and at least one non-silicone emollient. The siliconized polyamides have the silicone portion in the acid side of the polyamide and are selected so that: (a) the degree of polymerization in the silicone portion is in the range of 12-18; (b) the average molecular weight of the siliconized polyamide is at least 50,000 daltons with at least 95% of the polyamide having a molecular weight greater than 10,000 as measured by size exclusion chromatography; and (c) the polydispersity is less than 20.
清透的止汗剂和/或除臭剂配方,尤其是具有良好结构完整性的清透固体产品,可以通过将至少8%的选择性硅化聚酰胺按照配方总重量计入产品中来形成,该产品配方中包含至少一种硅材料和至少一种非硅乳化剂。硅化聚酰胺的硅部分位于聚酰胺的酸侧,并且选择这样的硅化聚酰胺:(a)硅部分的聚合度在12-18范围内;(b)硅化聚酰胺的平均分子量至少为50,000道尔顿,其中至少95%的聚酰胺具有大于10,000的分子量,通过尺寸排除色谱法测量;(c)聚分散度小于20。
