Appeal 2007-1144
Application 10/424,616
environment” (Specification 1). The Specification discloses that
“cholesterol sulfate, when applied topically to the skin, enhances the
cohesion of the stratum corneum resulting in a more prolonged retention of
the layers of the stratum corneum” (id. at 3). When cholesterol sulfate is
included in a typical self-tanning formulation, “the rate of turnover of the
stratum corneum to which the composition is applied is slowed down,
thereby permitting a longer rate of retention of the ‘tanned’ cells, and thus
prolonging the length of time the tan remains visible on the skin” (id. at 5).
DISCUSSION
1. CLAIMS
Claims 13-16 are on appeal. Claims 1-12 and 17-21 are also pending
but have been withdrawn from consideration by the Examiner. Claims
13-16 read as follows:
13. A method for artificially tanning the skin comprising
applying to the skin a composition comprising applying to the
skin[1] an effective amount of cholesterol sulfate and an
effective amount of at least one self-tanning agent.
14. A composition for artificially tanning the skin comprising
an effective amount of cholesterol sulfate and an effective
amount of at least one self-tanning agent.
15. The composition of claim 14 which comprises DHA as
the self-tanning agent.
16. The composition of claim 15, which also contains an
imidazole.
1 The second occurrence of “applying to the skin” in claim 13 appears to be
a typographical error.
