Definition

ChEBI: A carbamate ester that is carbamic acid in which the nitrogen has been substituted by a butyl group and in which the hydrogen of the carboxy group is replaced by a 1-iodoprop-2-yn-3-yl group. A fungicide, it is used as a preservative and sapstain control c emical in wood products and as a preservative in adhesives, paints, latex paper coating, plastic, water-based inks, metal working fluids, textiles, and numerous consumer products.

Reactivity Profile

Iodopropynyl butylcarbamate is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Contact allergens

Iodopropynyl butylcarbamate has produced slight irritation in rabbits. However, it was not found to be either a skin sensitizer or a photo sensitizer in guinea pigs. Cosmetic formulations containing up to 0.125% of iodopropynyl butylcarbamate produce no significant irritation or sensitization reactions in human repeated insult patch tests. Iodopropynyl butylcarbamate did not cause crosssensitization reactions in patients who had demonstrated sensitivity to related dithiocarbamate compounds. In the European Union, it is approved as a preservative up to 0.05% and is not to be used in oral hygiene or lip care products. If the concentration exceeds 0.02% in leave-on products, a warning label must indicate that the product contains iodine.
