The present invention provides for a
personal care composition suitable for treating hair comprising a composition comprising the
reaction product of a) an oxirane or
oxetane compound comprising at least two oxirane or
oxetane groups; and b) an amino
silane having the formula: N(H)(R1)R2Si(OR3)3-a-b-c(OR4)a(R5Si(OR6)d(R7)c)bR8c with R1 is chosen from the group consisting of H or a monovalent
hydrocarbon radical containing one to 20 carbon atoms; R2 is selected from a group consisting of a
divalent linear or branched
hydrocarbon radical consisting of 1-60 carbons; R4 is a
hydrocarbon radical that contains 3 to 200 carbon atoms; R5 is selected from a group consisting of
oxygen or a
divalent linear or branched hydrocarbon radical consisting of 1-60 carbons; R3, R6, R7, and R8 and are each independently selected from the group of monovalent linear or branched hydrocarbon radicals having from 1 to 200 carbon atoms; the subscript b is zero or a positive number and has a value
ranging from 0 to 3; the subscripts a is zero or appositive number less than 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.
