AI Technical Summary

Benefits of technology

The present invention relates to sanitizer compositions that have a pH range of about 4 to 8. These compositions effectively reduce microbial populations while being mild to the skin and being phase stable. The pH adjusting compound is present in an amount of about 0.05 to 3.5% by weight. The compositions may also include an antioxidant for improved skin condition and product stability. The antioxidant can be a natural or synthetic compound, such as retinol or ascorbic acid. The composition may also include a fragrance, which can be a natural or synthetic compound, such as citrus oil or peppermint oil. The fragrance can be added in an amount of about 0.001 to 2% by weight.

Problems solved by technology

Triclosan is disfavored as an antimicrobial agent due to environmental persistence and health concerns due to the possible formation of intermediate and / or environmental by products.

example 1

[0147]The following Figures demonstrate efficacy data of the present antimicrobial composition, using various cationic active ingredients, quaternary sugar-derived surfactants and optional foam boosting surfactants.

[0148]Table 7 and FIG. 1 (Log Kill of Cationic Active Ingredients):

[0149]The following figures illustrate the efficacy following a 30 second exposure time of three different cationic active ingredients, specifically, 0.5% Quat (Benzalkonium Chloride), 2% CHG (Chlorhexidine Gluconate), and 1% PHMB (polyhexamethylene biguanide) in a representative surfactant system.

[0150]Table 7 illustrates the formulas for the three cationic active ingredient systems tested. Both the quaternary sugar-derived surfactant and foam boosting surfactant were held constant and only the cationic active ingredient was changed between the three tests performed. The results are illustrated in FIG. 1.

Abstract

The antimicrobial composition of the present invention comprises a cationic active ingredient, a foam boosting surfactant, a foam boosting copolymer, a foam stabilizer, and a chelating agent. The present antimicrobial compositions are free of the antimicrobial agent triclosan (i.e., 2,4,4′-trichloro-2′hydroxy-diphenylether), have rapid cidal activity, provide stable copious foam and exhibit enhanced tissue (e.g. skin) compatibility as defined by an in vitro whole toxicology assessment method.

Description

FIELD OF THE INVENTION[0001]The present invention is directed to antimicrobial compositions, like personal care compositions, having improved antimicrobial efficacy and high foaming attributes. More particularly, the present invention relates to antimicrobial compositions exhibiting the antimicrobial effectiveness of cationic active ingredients, a foam boosting surfactant, a chelating agent, a novel foam boosting copolymer, with optional properties of a broad spectrum of antimicrobial efficacy, high foam and reduced irritation to mammalian tissue. The composition is essentially free of aromatic biocides such as triclosan, anionic surfactants and C1 to C4 alcoholsBACKGROUND OF THE INVENTION[0002]Antimicrobial personal care compositions are known in the art. Especially useful are antimicrobial cleansing compositions, which typically are used to cleanse the skin and to destroy bacteria and other microorganisms present on the skin, especially the hands, arms, and face of the user.[0003]...
