Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 270 words
An aqueous emulsion consisting essentially of a mixture of (1) silicone fluids in an amount of from 1 to 60 percent by weight based on the weight of the emulsion, said silicone fluids consisting essentially of (a) from 1 to 99 percent by weight based on the weight of the silicone fluids of an aminofunctional silicone fluid and (b) from 99 to 1 percent by weight based on the weight of the silicone fluids of an organopolysiloxane fluid, (2) a nonionic emulsifying agent in an amount of from 2 to 10 percent by weight based on the weight of the emulsion, (3) an ultraviolet radiation absorbing compound selected from the group consisting of p-aminobenzoic acid and a compound having the formula ##STR10## where R 1 is selected from the group consisting of a monovalent hydrocarbon radical having from 1 to 12 carbon atoms, an aminoalkyl radical having up to 6 carbon atoms; a monoalkanolaminoalkyl radical, a dialkanolaminoalkyl radical, an alkyl alkoxy radical having from 3 to 12 carbon atoms, a hydroxy substituted alkyl radical having from 2 to 6 carbon atoms, R 2 is selected from the group consisting of hydrogen, OH, OR 3 , NH 2 , NHR 3 , NR 2 3 and R 3 , R 3 represents an alkyl radical having from 1 to 4 carbon atoms and u is 0 or 1 with the proviso that when u is 0, R 2 is OH, OR 3 , NH 2 , NHR 3 and NR 2 3 and when u is 1, R 2 is hydrogen, OH, OR 3 and R 3 , and (4) water.
Claim 2
Dependent Claim 270 words
