Abstract
Abstract The composition comprises a first polar phase and a second nonpolar phase. The second phase is comprised of a plurality of discrete macroscopic bodies dispersed throughout the first phase. The first phase comprises a polar solvent having a polymer dissolved therein. The polymer imparts a Bingham yield value to the composition which is sufficient to retain the second phase in dispersion. The bodies impart to the composition an optical effect which can be enhanced by incorporating into said bodies differing colors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
35 words
A composition as described in claim 1 wherein said neutralized salt is prepared by neutralizing free carboxylic acid groups of said acidic copolymers with ammonium hydroxide, an alkanolamine, an alkali metal base or an amine.
Claim 2
Dependent Claim
23 words
A composition as described in claim 1 wherein said polar solvent is water, a water miscible lower aliphatic alcohol, or a mixture thereof.
Claim 3
Dependent Claim
22 words
A composition as described in claim 3 wherein said water-miscible aliphatic alcohol is glycerin, propylene glycol, ethanol, isopropanol or a mixture thereof.
Claim 4
Dependent Claim

A composition as described in claim 1 wherein oil-soluble cosmetic, perfume and pharmaceutical ingredients, which are incompatible, can be separated, with different colors, and used in the same base and wherein a portion of said bodies have incorporated therein a first incompatible oil-soluble ingredient and a first oil-miscible dye thereby rendering said portion one color, and another portion of said bodies have incorporated therein a second incompatible oil-soluble ingredient and a second oil-miscible dye thereby rendering said another portion a second color, said first and said second colors differing from each other, whereby said multicolored optical effect is enhanced and incompatible oil-soluble ingredients can be separated, with different colors, and used in the same base.
Claim 5
Dependent Claim
39 words
A composition as described in claim 5 wherein said first color and said second color are such that upon topical application of said composition with friction to a skin or otHer body surface a completely different third color results.
Claim 6
Dependent Claim
23 words
A composition as described in claim 1 further including a perfume, said perfume being dissolved within said bodies thereby substantially extending perfume life.
