Abstract
A method for dispensing an active volatile in the environment surrounding a surface, which comprises applying to the surface a self-adhering, water-resistant gel composition of at least one active volatile ingredient, silica, and a water-soluble cationic polysaccharide, and diffusing or releasing the volatile ingredient(s) from the gel in an amount sufficient to purify or sanitize the surrounding air, both in a dry condition or in the presence of humidity or water. The gel composition remains adhered to the surface and actively releases the volatile ingredient(s) even after being exposed to repeated water flows over the composition.
Claims20
A method for dispensing an active volatile in the environment surrounding a surface, which comprises applying to the surface a self-adhering, water-resistant gel composition comprising between 30 and 95% by weight, relative to the weight of gel composition, of at least one active volatile ingredient;
- silica in an amount of from 1 to 15% by weight;
- and a water-soluble cationic polysaccharide in an amount of from 0.1 to 6% by weight to provide strength to the gel;
- and diffusing or releasing the volatile ingredient(s) from the gel in an amount sufficient to purify or sanitize the surrounding air, both in a dry condition or in the presence of humidity or water;
- wherein the gel composition remains adhered to the surface and actively releases the volatile ingredient(s) even after being exposed to repeated water flows over the composition.
A self adhering, water resistant gel composition comprising:
- between 30 and 95% by weight, relative to the weight of gel composition, of at least one active volatile ingredient;
- silica in an amount of from 1 to 15% by weight;
- and
- a water-soluble cationic polysaccharide in an amount of from 0.1 to 6% by weight to provide strength to the gel;
- wherein the gel composition remains adhered to a surface and actively releases the volatile ingredient(s) even after being exposed at least 100 times to a flow of water over the composition.
