What is described herein are antimicrobial compositions which are defined blends of a 1,2-diol and phenoxyethanol which show broad activity against bacteria, fungi and mold spores. This activity is potentiated by the addition thereto of small amounts of a co-biocide for which the blend acts as a delivery system for the otherwise water-insoluble co-biocide.

Antimicrobial compositions

An antimicrobial composition of 3-iodo-2-propynylbutyl carbamate (IPBC) and 1,3-butylene glycol (BG) as solvent, in a defined weight ratio, preferably 9-11% IPBC and 89-91% BG, and personal care formulations including the composition in an amount of about 0.1-0.2% therein, at a pH of 4-9, is described.

Antimicrobial composition of 3-iodo-2-propynylbutyl carbamate and 1,3-butylene glycol as solvent

This invention relates to a broad spectrum antimicrobial composition, effective against gram negative and gram positive bacteria and fungi, which comprises a synergistic composition comprising iodopropynyl butyl carbamate and a bicyclic hydroxymethyl oxazolidine containing less than 0.1% of free formaldehyde.

Antimicrobial oxazolidine/iodopropynyl-butyl carbamate composition containing less than 0.1wt% free formaldehyde

This invention relates to a reaction product of allantoin and formaldehyde made in a molar ratio of about 1:2.75&#x2013;1:3.25, preferably 1:3, respectively, preferably under controlled pH (5.0 to 7.0) and temperature (40&#xb0; to 85&#xb0; C., preferably 50&#x2013;60&#xb0; C.) conditions, which product contains free formaldehyde (&#x3c;0.1%), and methylene diol of about 580&#x2013;1385 ppm, preferably at a pH of 7.2, with advantageous long-lasting, anti-microbial properties, particularly against the organism, and in combination products with parabens and iodopropynyl butyl carbamate (IPBC).

Long-lasting antimicrobial reaction product of allantoin and formaldehyde containing a low level of free formaldehyde

Preservative compounds

A high purity, water-white, clear, light stable, non-toxic, formaldehyde-free composition for inhibiting growth in a substance requiring microbial inhibition comprising about 40-60% by weight of an aqueous solution of hydroxymethylaminoacetate in the form of its alkali metal salt which is formed by the reaction of a salt of glycine, with formaldehyde, in an aqueous medium, at a pH of about 10.5-12.5, characterized by carrying out the reaction at a molar ratio of glycine to formaldehyde sufficient to maintain a molar excess of glycine in the medium and to leave a predetermined amount of residual glycine present in the composition at the conclusion of the reaction, and to preclude the presence of any detectable free formaldehyde as methylene diol in said composition.

High purity, clear, light stable, formaldehyde-free preservative compositions containing a compound formed by the reaction of excess glycine and formaldehyde at low temperatures

The hydroxybenzoate compounds of this invention are defined by the formula:

Aliphatically unsaturated hydroxy benzoates and preservative compositions thereof

The antimicrobial preservative composition consisting essentially of (a) from 0.5 to 20 wt. % dihalogenated butane having terminal cyano groups and (b) from 80 to 99.5 wt. % of a heterocyclic poly(hydroxy lower alkylamide) in a weight ratio of between 0.5:2 and 0.5:25 which mixture exhibits a synergistic antimicrobial affect over each of components (a) or (b) taken individually.

Antimicrobial preservative composition

What is described herein is a cosmetic composition of an alpha-hydroxy acid, such as lactic acid or glycolic acid, or a beta-hydroxy acid, such as salicylic acid, and a polyvinylpyrrolidone-complexing agent, or derivative thereof, in a suitable solvent, useful for the treatment of skin problems, with only minimal skin irritation for the user.

Cosmetic composition of an alpha or beta-hydroxy acid and a

A process is provided for making a free-flowing powder of a complex of an alpha-hydroxy acid (AHA) and/or a beta-hydroxy acid (BHA) and a vinylpyrrolidone (PVP) polymer, copolymer or graft polymers, as the complexing agent, at high acid loadings, preferably 20-60% by weight. The presence of VP polymers, copolymers or graft polymers in the complex reduces the skin irritation effect of the acid when applied to the skin of the user. The process involves applying an aqueous solution or slurry of the acid to PVP, and, substantially immediately thereafter, evaporating the water to form a free-flowing powder of the complex of the acid and VP polymers, copolymers or graft polymers.

Synergistic water soluble preservative compositions of biocidal mixtures

A water soluble preservative admixture of biocidal compounds for addition to commercial use compositions at predetermined use levels, and uniformly distributed therein, to provide long-time synergistic biocidal activity against a wide range of fungi and both gram-negative and gram-positive bacteria, which comprises powders of (a) one or more methylol compounds, or their equivalents, and (b) iodopropynyl alcohol, or its ester, carbamate or ether derivative thereof, in a weight ratio of (a):(b) of 100:1 to 2000:1.

A water soluble, antimicrobial composition having antifungal activity useful for disinfecting a contact lens comprise (a) polyhexamethylene biguanide and (b) iodopropynylbutyl carbamate, in a weight ratio of (a):(b) of at least 100:1.
