Abstract
A preservative system comprising iodopropynyl butyl carbamate and phenoxyethanol at a weight ratio of iodopropynyl butyl carbamate to phenoxyethanol within the range of about 1:90 to about 1:400 shows a broad anti-microbial effect and can permit use of the preservative system at a low level in end use products such as personal care products.
Claims22
A personal care product comprised of a chemical composition comprised of a preservative system comprising an iodopropynyl butyl carbamate and phenoxyethanol at a weight ratio of iodopropynyl butyl carbamate to phenoxyethanol within the range of about 1:90 to about 1:400, whereby the iodopropynyl butyl carbamate and phenoxyethanol are present in an effective anti-microbial amount for a two component preservative system and said preservative system possesses synergistic preservative action properties.
A method of preserving a personal care product comprising:
- admixing iodopropynyl butyl carbamate and phenoxyethanol in a personal care product, whereby the iodopropynyl butyl carbamate and phenoxyethanol are present in an effective anti-microbial amount for a two component preservative system and the preservative system possesses synergistic preservative action properties.
A method for making a chemical composition comprising a preservative system comprising
- a) admixing iodopropynyl butyl carbamate and phenoxyethanol at a weight ratio of iodopropynyl butyl carbamate to phenoxyethanol within the range of about 1:90 to about 1:400, whereby the iodopropynyl butyl carbamate and phenoxyethanol are present in an effective anti-microbial amount for a two component preservative system and the preservative system possesses synergistic preservative action properties;
- and
- b) incorporating the preservative system in a personal care product.
A method for making a personal care product comprising
- incorporating iodopropynyl butyl cerbamate and phenoxyethanol at a weight ratio of iodopropynyl butyl carbamate to phenoxyethanol within the range of about 1:90 to about 1:400 to the product, whereby the iodopropynyl butyl carbamate and phenoxyethanol are present in an effective anti-microbial amount for a two component preservative system and the preservative system possesses synergistic preservative action properties.
