United States Patent:  6,033,651

Assignee:   Revlon Consumer Products Corporation (New York, NY)

Filed:  December 18, 1998

A single phase aqueous gel composition comprising 0.05-50% of a polysaccharide gellant, and 1-30% of an antiperspirant active ingredient solubilized in the aqueous single phase. A water and oil emulsion comprising a gelled aqueous phase comprising a polysaccharide gellant and an antiperspirant active ingredient solubilized in the aqueous single phase; and an oil phase. A method for preparing an emulsion antiperspirant or deodorant composition comprising preparing a first aqueous solution of antiperspirant or deodorant active, preparing a second aqueous solution of polysaccharide gellant, emulsifying the second aqueous solution in an oily phase to form an emulsion, combining the first aqueous solution and the emulsion so that the first and second aqueous solutions form a single homogeneous phase in the emulsion; and pouring the mixture into containers.

SUMMARY OF THE INVENTION

The invention comprises a single phase aqueous gel composition comprising, by weight of the total composition aqueous gel phase composition:

0.05-50% of a polysaccharide gellant, and

1-30% of an antiperspirant active ingredient solubilized in the aqueous single phase.

A water and oil emulsion solid composition comprising, by weight of the total water and oil emulsion solid composition:

1-85% of a single phase aqueous gel composition comprising a polysaccharide gellant and an antiperspirant active solubilized in the single phase, and

0.1-75% of an oily phase.

The invention comprises a method for making an antiperspirant/deodorant composition comprising the steps of:

(a) preparing a first aqueous solution of antiperspirant/deodorant active,

(b) preparing a second aqueous solution of polysaccharide gellant,

(c) emulsifying the second aqueous solution in an oily phase to form an emulsion,

(d) combining the first aqueous solution and the emulsion wherein the first and second aqueous solutions form a single homogeneous phase in the emulsion; and

(d) pouring the mixture into containers.

Claim 1 of 19 Claims

1. A water and oil emulsion solid composition comprising a single gelled aqueous phase comprising a polysaccharide gellant selected from the group consisting of galactan, galactomannan, and mixtures thereof, and an antiperspirant active ingredient solubilized in the aqueous single phase; and an oil phase
