Appeal No. 2002-0519 Page 2
Application No. 09/668,959
organic solvents are routinely used to break emulsions into separate phases to analyze
content (specification, page 2, first paragraph).
Applicants' invention is based on the finding that when silicone polyethers are
used to prepare organic oil-in-water (O/W) emulsions, the resulting formulations are
stable in the presence of salts such as calcium chloride and aluminum sulfate; alcohols
such as methanol, ethanol, propanol, and isopropanol; and organic solvents such as
pentane (specification, page 4, third paragraph). According to applicants, when a
silicone polyether is used to make an organic O/W emulsion, or a silicone polyether is
added to a previously prepared organic O/W emulsion, the emulsion is stable in the
presence of a salt, an alcohol, an organic solvent, or a combination thereof. Such
stability is an advantage and benefit in personal care, household care, automotive care,
and coating industry applications (specification, page 2, second paragraph).
Claims 1, 5, 9, 13, 19, and 21, which are illustrative of the subject matter on
appeal, read as follows:
1. A composition comprising (i) 1-30 percent by weight of a salt component, and
(ii) 70-99 percent by weight of an organic oil-in-water emulsion; the organic oil-in-water
emulsion comprising 5-80 percent by weight of a non-silicon atom containing organic
oil, 0.1-20 percent by weight of a silicone polyether surfactant, and 20-90 percent by
weight of water.
5. A composition comprising (i) 1-80 percent by weight of an alcohol component,
and (ii) 20-99 percent by weight of an organic oil-in-water emulsion; the organic oil-in-
water emulsion comprising 5-80 percent by weight of a non-silicon atom containing
organic oil, 0.1-20 percent by weight of a silicone polyether surfactant, and 20-90
percent by weight of water.
9. A composition comprising (i) 1-99 percent by weight of a solvent component,
and (ii) 1-99 percent by weight of an organic oil-in-water emulsion; the organic oil-in-
water emulsion comprising 5-80 percent by weight of a non-silicon atom containing
