The invention relates to a compound of the following formula (I) X—CR1R2R3 wherein —R1 is an organic moiety having 6 to 24 carbon atoms; —R2 is H or an organic moiety having 6 to 24 carbon atoms; —R3 is X or OH; —X is a moiety of the following formula (II): or an ammonium or C1-C4 alkyl ammonium salt of the moiety of formula (II); wherein -x is 0 or 1; -y is 0 or 1; -z is 0 or 1; -m is a number from 2 to 10; -n is a number from 0 to 10; -o is a number from 0 to 10; —R4 is H or a C1-C4 alkyl group; —R5 is a C6-C22 alkyl or alkenyl group or, if n or o is at least 1, a C7-C23 acyl group; —R6 is H or R5; —R7 is a C1-C4 alkylene group. which is capable of delivering aldehyde-type or ketone-type fragrance compounds, providing a long-lasting release of said fragrance compounds. This compound can be incorporated into fiber conditioning compositions, such as hair conditioners and fabric softeners, to enhance the fragrance performance. The compound provides controlled release from the substrate where it has been deposited over an extended period of time. |
