Abstract
A detergent composition and a method of washing/cleaning urushiol at least partially, more typically substantially or completely off a surface of human skin or clothing. The detergent composition is typically a non-buffered composition that contains one or more C12 surfactants, typically at least a sodium lauroyl sarcosinate and the detergent composition is typically free of one or more of (1) any nonylphenol ethoxylate; (2) any pharmaceutically active drug or prodrug; (3) any salt in an amount that affects the functional characteristics of either of the solely C12 surfactants; (4) any salt in granular form; and/or (5) any ethoxylate that is a stand-alone ingredient.
Claims20
A detergent composition for washing an area of a person's skin having urushiol thereon or an item of clothing having urushiol on a surface of the item of clothing, wherein the detergent composition comprises:
- water in an amount of from 40 to 60 weight percent of the detergent composition and wherein the water is added as a separate and independent component of the detergent composition;
- surfactants, wherein the surfactants consist of a sodium lauroyl sarcosinate, a sorbitan monolaurate, and a non-ionic polyethylene glycol ether of a mixture of synthetic C12-15 fatty alcohols with an average of 9 moles of ethylene oxide;
- and
- wherein the detergent composition is not buffered;
- and the detergent composition is free of each of the following:
- (1) any nonylphenol ethoxylate, (2) any pharmaceutically active drug or prodrug, (3) any salt in granular form;
- (4) any ethoxylate that is a stand-alone ingredient;
- and (5) any ethoxylate that is not part of the non-ionic polyethylene glycol ether of a mixture of synthetic C12-c15 fatty alcohols with an average of 9 moles of ethylene oxide.
A detergent composition comprising:
- water;
- a hydrophilic, and cross-linked polyacrylic acid polymer having an HLB of 10 or greater;
- at least one type of bio-degradable bead having a maximum particle size of 300 microns;
- a silicone copolyol wetting agent;
- a sodium lauroyl sarcosinate;
- optionally, a non-ionic C12 surfactant;
- a non-ionic polyethylene glycol ether of a mixture of synthetic C12-15 fatty alcohols with an average of 9 moles of ethylene oxide;
- a disodium EDTA;
- a sodium hydroxide;
- and
- wherein the detergent composition is free of:
- (1) any nonylphenol ethoxylate, (2) any pharmaceutically active drug or prodrug, (3) any salt in an amount that affects the functional characteristics of any C12 surfactant present in the detergent composition;
- (4) any ethoxylate that is a stand-alone ingredient;
- and (5) the detergent composition is free of any ethoxylate that is not part of the non-ionic polyethylene glycol ether of a mixture of synthetic C12-c15 fatty alcohols with an average of 9 moles of ethylene oxide.
A composition consisting of:
- water;
- a hydrophilic, and cross-linked polyacrylic acid polymer;
- at least one type of bio-degradable bead having a maximum particle size of 300 microns;
- a silicone copolyol wetting agent;
- a sodium lauroyl sarcosinate solution;
- optionally, a second C12 surfactant;
- a non-ionic polyethylene glycol ether of a mixture of synthetic C12-15 fatty alcohols with an average of 9 moles of ethylene oxide;
- a quaternary ammonium salt;
- a disodium EDTA;
- and
- a sodium hydroxide.
