This invention relates to personal care compositions, and, more specifically, to a composition comprising a pyrithione salt or acid, a basic lipopeptide, and a suitable carrier. The pyrithione plus the lipopeptide provide antimicrobial efficacy to the personal care composition. The personal care composition is useful in a variety of dermatological items, such as soaps, shampoos, and skin care medicaments.

Personal care composition containing pyrithione and a basic lipopeptide

The present invention relates to a composition comprising a antimicrobially effective amount of a combination of an pyrithione and a lipopeptide antibiotic. Also disclosed is an aqueous industrial functional fluid comprising an aqueous base fluid medium and an antimicrobially effective amount of a combination of a pyrithione and a lipopeptide antibiotic. Also disclosed is a process for providing biocidal activity to an aqueous industrial functional fluid which comprises incorporating into said fluid an antimicrobially-effective amount of a combination of a pyrithione and a lipopeptide antibiotic.

Synergistic biocide combination for industrial fluids

In accordance with the present invention, a new pyrithione salt, namely chitosan pyrithione, is produced. This composition is characterized by a combination of slow release from films and excellent antimicrobial activity. The antimicrobial activity is equivalent to that of sodium pyrithione. These properties make chitosan pyrithione potentially useful as an antimicrobial agent in a variety of dermatological items, such as soaps, shampoos, and skin care medicaments.

Chitosan pyrithione as an antimicrobial agent useful in personal care

In accordance with the present invention, a new pyrithione salt, namely chitosan pytighione, is produced. This composition is characterized by a combination of slow release from films and excellent antimicrobial activity. The antimicrobial activity is equivalent to that of sodium pyrithione. These properties make chitosan pyrithione potentially useful as an antimicrobial agent in a variety of dermatological items, such as soaps, shampoos, and skin care medicaments.
