Abstract

Combination powdered material, including a first powder composition and a second powder composition, the first powder composition including cellulose particulate material and the second powder composition including starch particles, alone or in combination with talc particles.

Claims (15)

1. A solid powder composition to be applied to the skin comprising:

a. a first powder component comprising corn starch powder; and

b. a second powder component comprising a plurality of particles comprising linear hydrophobic cellulose particles, wherein said linear hydrophobic cellulose particles are derived from cotton, wherein said cotton is regenerated cotton, wherein said linear hydrophobic cellulose particles have a length of about 2 microns to about 500 microns; wherein said linear hydrophobic cellulose particles have a diameter of about 1 to about 25 microns; and wherein said linear hydrophobic cellulose particles have an aspect ratio of about 2 to about 10;

wherein said first powder component and said second powder component are present in said solid powder composition in a ratio of about 90:10 by weight of each component; and

wherein when said solid powder composition is applied to the skin, said cellulose particles result in reduced release of particulates into the air in the vicinity of the skin as compared to a composition comprising corn starch alone;

wherein said solid powder composition can be more accurately applied to a target site as compared to a composition comprising corn starch alone.

2. The solid powder composition of claim 1 , further comprising a third powder component comprising a plurality of particles comprising talc.

3. A method of reducing dusting of a particulate composition comprising combining a first powder component comprising corn starch powder with a second powder component comprising a plurality of particles comprising linear hydrophobic cellulose particles,

wherein said linear hydrophobic cellulose particles are derived from cotton, wherein said cotton is regenerated cotton;

wherein said linear hydrophobic cellulose particles have a length of about 2 microns to about 500 microns;

wherein said linear hydrophobic cellulose particles have a diameter of about 1 to about 25 microns; and

wherein said linear hydrophobic cellulose particles have an aspect ratio of about 2 to about 10;

wherein said first powder component and said second powder component are combined in a ratio of about 90:10 by weight of each component;

thereby forming a combination particulate composition with a lesser dusting profile than a composition that contains said first powder component without said second powder component.

4. A method of reducing skin irritation comprising the step of applying to a target skin site the solid powder composition of claim 1 .
