Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
258 words
In an antiperspirant stick composition consisting essentially of, based on the total weight of the composition: (a) from about 16% to about 35% by weight of a low melting wax selected from the group consisting of a fatty acid containing from about 8 to 22 carbon atoms, a fatty alcohol containing from about 8 to about 22 carbon atoms, a silicone wax and glycerol monostearate; (b) from about 20% to 60% of an emollient; and (c) from about 10% to 50% of an antiperspirant material; the improvement which comprises: (d) from about 0.5% to about 10.0% of the additional waxy agent FT-300 Wax incorporated in said stick composition, said FT-300 Wax being characterized in that it is a saturated, synthetic hard paraffin of formula CH 3 (CH 2 ) n CH 3 and is chemically neutral, colorless and high melting; is free from aromatic and unsaturated compounds and contains neither sulfur nor any halogens; has a structure that is characterized as fine crystalline; appearance in the solid state is white and opaque; and forms a clear solution in the common wax solvents at elevated temperature it is practically insoluble and has the following properties: ______________________________________
