Abstract
Disclosed herein is an eco-friendly, non-aqueous and stable antimicrobial solution composition comprising (a) about 0.1 to 20.0 wt % of a Hinokitiol; and (b) about 80.0 to 99.9 wt % of bio-derived 1,3-propanediol and/or bio-derived sorbitan caprylate. Also disclosed is a process for preparing and method of using the composition. In accordance with another aspect of the present application, the eco-friendly, nonaqueous antimicrobial composition is capable of inhibiting or killing gram (+) bacteria, gram (−) bacteria, yeasts and/or fungi.
Claims18
An eco-friendly, non-aqueous and stable antimicrobial solution composition comprising:
- a. about 0.1 to 20.0 wt % of a Hinokitiol;

- and
- ii. heating the mixture of step (i) at about 40° C. to yield a homogenous non-aqueous antimicrobial solution.
An eco-friendly, non-aqueous and stable antimicrobial solution composition comprising:
- a. about 0.1 to 20.0 wt % of a Hinokitiol;
- and
- b. about 49.95 to 40.0 wt % of (i) 1,3-propanediol, a bio-derived solvent;
- and about 49.95 to 40.0 wt % of (ii) sorbitan caprylate, a bio-derived solvent.
An eco-friendly, non-aqueous and stable antimicrobial solution composition comprising:
- a. about 2.0 wt % of a Hinokitiol;
- and
- b. about 49.0 wt % of (i) 1,3-propanediol, a bio-derived solvent;
- and about 49.0 wt % of (ii) sorbitan caprylate, a bio-derived solvent.
