Appeal No. 1998-2543
Application 08/606,939
Where R1 is a C13-C20 branched alkyl or linear alkenyl; R2 is C11-C18 linear or branched
alkyl or C11-18 linear alkenyl; and R3 is C1-C6 linear, branched or cyclic alkyl. As
explained in the Appeal Brief (Paper No. 13), page 4, applicants’ phosphoric triesters are
characterized by having two “R” groups which are long in carbon atom length (R1 is C13-
C20 and R2 is C11-18), with a third “R” group being quite short in carbon atom length (R3 is
C1-C6). Accordingly, the present phosphoric triesters present an “asymmetric”
configuration, i.e., R1, R2, and R3 are long, long, and short, respectively. On combination
with a suitable carrier, these triesters form an “external” composition, useful in the cosmetic
industry and said to have excellent compatibility with the skin, good sensation or feel during
use, and a high degree of safety.
