Claim:
A personal care composition suitable for treating hair comprising a composition comprising the reaction product of a) oxirane or oxetane compound comprising at least two oxirane or oxetane groups; and b) an amino silane having the formula: N(H)(R 1 )R 2 Si(OR 3 ) 3-a-b-c (OR 4 ) a (R 5 Si(OR 6 ) d (R 7 ) e ) b R 8 c with R 1 is chosen from the group consisting of H or a monovalent hydrocarbon radical containing one to 20 carbon atoms; R 2 is selected from a group consisting of a divalent linear or branched hydrocarbon radical consisting of 1-60 carbons; R 4 is a hydrocarbon radical that contains 3 to 200 carbon atoms; R 5 is selected from a group consisting of oxygen or a divalent linear or branched hydrocarbon radical consisting of 1-60 carbons; R 3 , R 6 , R 7 , and R 8 and are each independently selected from the group of monovalent linear or branched hydrocarbon radicals having from 1 to 200 carbon atoms; the subscripts a is zero or a positive number less than or equal to 3, the subscripts b and c are zero or positive and have a value ranging from 0 to 3 subject to the limitation that (a+b+c)≦3; the subscripts d and e are zero or positive and have a value ranging from 0 to 3 subject to the limitation that (d+e)=3, wherein when hair is treated with said personal care composition said hair has a hydrophobic response to water or wherein when human skin is treated with said personal care composition said skin exhibits an enhanced hydrophobic response to water, wherein the oxirane or oxetane compound is a siloxane having the formula: M E h D k wherein M E =R 12 R 13 (R E )SiO 1/2 D=R 18 R 19 SiO 2/2 where R 12 , R 13 , R 18 , and R 19 are methyl groups, R E is —(CH 2 ) 3 OCH 2 CH(O)CH 2 subscript h is 2 and subscript k is 50.
