AI Technical Summary

Benefits of technology

The compositions demonstrate enhanced antimicrobial activity against viruses and bacteria, including Gram-negative bacteria, while maintaining skin mildness and stability, without causing dryness or irritation, and can be used with or without water.

Problems solved by technology

However, conventional anionic surfactants have been associated with low solubility under acidic conditions, poor compatibility with cationic antimicrobial agents, slow dissolution kinetics and limited residual antimicrobial performance.

Antimicrobial Hand Sanitizer

[0061]To deliver the benefits of the present invention in a hand sanitizer form, the liquid composition produced in accordance with the previous section may be packaged in a typical PET bottle with a flip-top cap. Liquid is dispensed to the hands in an amount to ensure complete wetting. Employing this method delivers immediate microbial kill and, upon drying, provides prolonged, residual activity.

Antimicrobial Wipe

[0062]The lotion produced in accordance with the previous section may be used to produce a wet wipe product for topical cleaning and / or sanitizing of skin and / or hard surfaces. Such a product is made by saturating a paper or cloth substrate with the liquid composition prepared in accordance with the previous section. The level of saturation depends upon the substrate in which incorporation of the antimicrobial composition is desired. A 5″×8″ hand wipe towelette made from 40-60 grams per square meter spun-lace non-woven material may be saturated with about 1-3 grams of liquid composition. The liquid may be applied to the substrate via spraying and / or soaking prior to final packaging. The wipe may be wrapped in single use pouches made from foil or plastic or packed in groups of 10, 40, or more in multiple use tubs.

[0063]To deliver the benefits of the present invention in this form, the wipe is removed from its package and is rubbed onto the target surface, in a manne...

Antimicrobial Drying Towel

[0064]The lotion produced in accordance with the previous section may be used to produce a dry towel product for topical cleaning and / or sanitizing of skin or hard surfaces. Such a product is made by saturating a paper or cloth substrate with the liquid prepared in accordance with the preceding section. The substrate is then dried to remove all water. The level of saturation depends upon the substrate in which incorporation of the antimicrobial composition is desired. A 5″×8″ towel made from 40-60 grams per square meter spun-lace non-woven material may be saturated with about 1-3 grams of liquid. The liquid may be applied to the substrate via spraying and / or soaking prior to final packaging. The liquid may also be applied in concentrate form using printing techniques employed in the color design of commercial, paper towels. The towel may then be rolled or inserted into boxes.

[0065]To deliver the benefits of the present invention in this form, the towel is a...
