Appeal No. 95-3969
Application 08/181,273
Claimed Subject Matter
The claims on appeal are directed to a cosmetic product and a method of using the same. The
cosmetic product is dispersed from a multi-compartment dispenser wherein a first substance is dispersed
from one compartment and a second substance is dispersed from a second compartment. The first
substance is an anhydrous composition comprising ascorbic acid and a carrier and the second substance
is an aqueous composition of an alkaline agent having a pH from about 7 to about 11. Claim 1 is
representative of the claimed subject matter and reads as follows:
1. A cosmetic product which is formed as a multi-compartment dispenser, wherein a first
and second substance are stored apart from one another in separate compartments of the
dispenser:
(i) the first substance being an anhydrous composition comprising:
a) from 0.001 to 50% by weight of ascorbic acid; and
b) from 5 to 99.9% by weight of a pharmaceutically acceptable carrier; and
(ii) the second substance being an aqueous composition with a pH ranging from about 7
to about 11 comprising from 40 to 99% water and 1 to 30% of an alkaline agent present
in an effective amount to cause a rise of at least 0.5 units in pH of the first substance when
blended therewith, and wherein the first and second substances are blended together just
prior to use so as to topically deliver a final blended composition to skin whose acidity is
insufficient to cause irritation but, nevertheless, delivers active ascorbic acid.
