Abstract
Abstract The present invention consists of methods for using certain cationic alkyl phosphate derivatives as sanitizing agents in plastic materials for providing fungicidal and bactericidal properties which are effective against both Gram-positive and Gram-negative organisms including Pseudomonas aeruginosa. Various plastic materials of the invention are shown utilizing various sanitizing agents.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A self-sanitizing, carpet product including thermoplastic surface yarn and a backing coat, said carpet product having an upper portion, and said backing coat including as a homogeneously distributed additive therein, an alkyl phosphate of the formula: ##STR4## where: R 3 =an alkyl group of up to 18 carbon atoms; R 4 =R 3 said alkyl phosphate being present in said backing coat at a concentration of between 0.01% and 10% by weight based on the weight of said backing coat, and said backing coat being selected from the group consisting of a polyvinyl chloride emulsion and a styrene butadiene resin; and said backing coat and said surface yarn being constructed and arranged so that alkyl phosphate in said backing coat will migrate by capillary action from said backing coat toward said upper portion of said carpet product to inhibit the growth of microorganisms therein.
Claim 2
Dependent Claim
144 words
A self-sanitizing, carpet product including thermoplastic surface yarn and a backing coat, said carpet product having an upper portion, and said backing coat including as a homogeneously distributed additive therein, an alkyl phosphate of the formula: ##STR4## where: R 3 =an alkyl group of up to 18 carbon atoms; R 4 =R 3 said alkyl phosphate being present in said backing coat at a concentration of between 0.01% and 10% by weight based on the weight of said backing coat, and said backing coat being selected from the group consisting of a polyvinyl chloride emulsion and a styrene butadiene resin; and said backing coat and said surface yarn being constructed and arranged so that alkyl phosphate in said backing coat will migrate by capillary action from said backing coat toward said upper portion of said carpet product to inhibit the growth of microorganisms therein.
Claim 3
Dependent Claim
141 words
Method of forming a self-sanitizing carpet product including thermoplastic surface yarn and a backing coat, wherein said carpet product has an upper portion, and said backing coat is selected from the group consisting of polyvinyl chloride emulsion and styrene butadiene resin, said method comprising emulsion and styrene butadiene resin, said method comprising the steps of: a. homogeneously incorporating into said backing coat from 0.01% to 10% by weight based on the weight of said backing coat, an alkyl phosphate of the formula: ##STR5## where: R 3 =an alkyl group of up to 18 carbon atoms; R 4 =R 3 ; b. then applying said backing coat to said carpet product; and c. Permitting said alkyl phosphate additive to migrate by capillary action from said backing coat toward the upper portion of said carpet product to inhibit the growth of microorganisms therein.
Claim 4
Dependent Claim
141 words
Method of forming a self-sanitizing carpet product including thermoplastic surface yarn and a backing coat, wherein said carpet product has an upper portion, and said backing coat is selected from the group consisting of polyvinyl chloride emulsion and styrene butadiene resin, said method comprising emulsion and styrene butadiene resin, said method comprising the steps of: a. homogeneously incorporating into said backing coat from 0.01% to 10% by weight based on the weight of said backing coat, an alkyl phosphate of the formula: ##STR5## where: R 3 =an alkyl group of up to 18 carbon atoms; R 4 =R 3 ; b. then applying said backing coat to said carpet product; and c. Permitting said alkyl phosphate additive to migrate by capillary action from said backing coat toward the upper portion of said carpet product to inhibit the growth of microorganisms therein.
