Abstract
The present development relates to a liquid cleansing product that effectively reduces the level of microbes on the skin in a relatively short wash time and which dries quickly without causing damage and drying to the skin. The sanitizing cleanser composition comprising an effective amount of alcohol to produce a reduction in microorganisms on the surface of the skin, and an additive to maintain the skin pH in the range of from about 4.0 to about 6.0. The cleanser composition may further include silicone to aid further the drying process, and emollients or oils for skin moisturizing.
Claims60
A waterless sanitizing hand cleanser consistently essentially of:
- from about 60 wt. % to about 90 wt. % of one or more organic alcohols;
- from about 5 wt. % to about 35 wt. % of one or more silicone based materials;
- up to about 5 wt. % of one or more humectants;
- up to about 12 wt. % of one or more skin pH-maintaining additive;
- and
- one or more thickening agents added at a concentration so as to produce a product with a viscosity in the range of 100 cp to 100,000 cp at about 25° C.
A sanitizing hand cleanser consisting essentially of:
- a) an alcohol mixture, prepared by mixing from about 60 wt. % to about 90 wt. % of one or more alcohols with from about 5 wt. % to about 35 wt. % of one or more silicone based materials, up to about 5 wt. % isopropyl myristate, up to about 5.0 wt. % lactic acid and up to about 2.0 wt. % sodium lactate at ambient temperature until well blended;
- and
- b) a thickening mixture, prepared by removing a portion of said alcohol mixture to a separate mixing vessel and adding up to about 1.5 wt. % methyl cellulose while maintaining continuous mixing,
- wherein said thickening mixture is combined with said alcohol mixture at ambient temperature and with continuous mixing until reaching a product viscosity of from about 250 cp to about 450 cp at about 25° C., said alcohol mixture and said thickening mixture being prepared in the absence of water.
A method of making a sanitizing hand cleanser consistently essentially of the steps of:
- a) mixing from about 60 wt. % to about 90 wt. % of one or more alcohols with from about 5 wt. % to about 35 wt. % of one or more silicone based materials, up to about 5 wt. % isopropyl myristate, up to about 5.0 wt. % lactic acid and up to about 2.0 wt. % sodium lactate at ambient temperature until well blended;
- b) adding up to about 1.5 wt. % methyl cellulose to a portion of said mixture formed in step a) and mixing until well blended;
- and
- c) adding said methyl cellulose mixture to said mixture formed in step a) at ambient temperature and with continuous mixing until reaching a product viscosity of from about 250 cp to about 450 cp at about 25° C.
A waterless sanitizing hand cleanser comprising:
- from about 60 wt. to about 90 wt. % of one or more alcohols;
- from about 11 wt. % to about 35 wt. % of one or more silicone based materials;
- up to about 5 wt. % of one or more humectants;
- up to about 10 wt. % of one or more antimicrobial agents;
- up to about 12 wt. % of one or more skin pH-maintaining additive;
- and
- one or more thickening agents added at a concentration so as to produce a product with a viscosity in the range of 100 cp to 100,000 cp at about 25° C.
