A chemical composition comprising a linker agent and a compound comprising at least one UV-absorbing chromophore, wherein the linker agent is characterized by the general formula: wherein Xand Xare the same or different, and at least one of Xor Xis a functional group that bonds with the compound comprising at least one UV-absorbing chromophore, and b+f&#x2267;2, Y comprises an O, N, or S that is substituted or unsubstituted, each a, b, c, e and f is &#x2267;0 and a+b+c+e+f&#x2267;2, d is 0 or 1, n1 and n2 represent the number of hydrogen atoms required to complete the undesignated valencies, and m ranges from 1 to about 100 and each individual m unit may be the same or different.

Compositions comprising a UV-absorbing chromophore

A product for topical application comprising a chemical composition comprising in combination a linker agent and a compound comprising at least one UV-absorbing chromophore, wherein the linker agent is characterized by the general formula: 

Formulations with feruloyl glycerides and methods of preparation

A method of making a compound having the structural formula:  wherein at least two of R, R, and Rare non-fatty acid carboxylates, and the other of R, R, and Rare each either a C-Cfatty acid moiety, OH, or a non-fatty acid carboxylate, wherein the first and second non-fatty acid carboxylates, when present, are the same or different, comprising (a) partially deacylating a triacylglycerol so as to provide a mono- or diacylglycerol, (b) reacting in a reaction mixture an acyl ester of the phytochemical with said mono- or diacylglycerol in the presence of a esterase catalyst under conditions that permit transesterification of said ester with said mono- or diacylglycerol, and (c) recovering said compound from said reaction mixture.
