Abstract

A method of stabilizing alcohol-based hand sanitizers comprising providing a first composition of matter that is a combination of a linear dimethicone copolyol, an alkylene oxide adjuvant selected from the group consisting of polyethylene oxide, and, polypropylene oxide, and, an alcohol, then, combining the first composition of matter with an alcohol-based hand sanitizer. A composition of matter comprising linear dimethicone copolyol, an alkylene oxide adjuvant selected from the group consisting of polyethylene oxide, and, polypropylene oxide, and, an alcohol, and, a further composition of matter comprising linear dimethicone copolyol, an alkylene oxide adjuvant selected from the group consisting of polyethylene oxide, and, polypropylene oxide, and, an alcohol combined with an alcohol-based hand sanitizer.

Claims

1. A novel method of stabilizing alcohol-based hand sanitizers comprising:

I. providing a first composition of matter that is a combination of

i. a linear dimethicone copolyol;

ii. an alkylene oxide adjuvant selected from the group consisting of

a. polyethylene oxide, and,

b. polypropylene oxide, and,

iii. an alcohol;

II. combining said first composition of matter with an alcohol-based hand sanitizer.

2. A composition of matter comprising:

a. a linear dimethicone copolyol;

b. an alkylene oxide adjuvant selected from the group consisting of

i. polyethylene oxide, and,

ii. polypropylene oxide, and,

c. an alcohol.

3. A composition of matter as claimed in claim 2 wherein the alkylene oxide adjuvant is selected from PEG 8 to PEG 12.

4. A composition of matter as claimed in claim 2 wherein the alkylene oxide adjuvant is selected from polypropylene glycol.

5. A composition of matter comprising:

a. a linear dimethicone copolyol;

b. an alkylene oxide adjuvant selected from the group consisting of

i. polyethylene oxide, and,

ii. polypropylene oxide, and,

c. an alcohol;

d. an alcohol-based hand sanitizer.

6. A composition of matter as claimed in claim 5 wherein the alkylene oxide adjuvant is selected from PEG 8 to PEG 12.
