  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.

  mixture of a carboxylic acid and an alkali metal carboxylate group-containing rubber in a vinyl monomer is provided. The resulting composition has a relatively low viscosity and is particularly adapted for preparing a thermosettable composition suitable for preparing reinforced plastic articles by combining an unsaturated polyester, the alkali metal carboxylate-containing rubber solution containing the carboxylic acid, a catalyst, and a reinforcing agent. The resulting composition when cured exhibits high impact strength and good surface finish.
