Abstract

A WASH CYCLE ADDITIVE ANTISTATIC COMPOSITION, WHICH, WHEN ADDED TO A WASH WATER IN A WASHING MACHINE, MAKES LAUNDRY WASHED IN SUCH AUTOMATIC WASHING MACHINE AND DRIED IN AN AUTOMATIC LAUNDRY DRYER RESISTANT TO THE ACCUMULATION OF STATIC CHARGES THEREON, AND WHICH MAY BE IN PARTICULATE, LIQUID OR OTHER SUITABLE FORM, COMPRISES AN ANTISTATIC POLYAMIDE OF TRIALKYLACETIC ACID AND POLYAMINE, WHEREIN THE ALKYLS OF THE TRIALKYLACETIC ACID MOIETY ARE OF 1 TO 10 CARBON ATOMS EACH AND THE POLYAMINE MOIETY CONTAINS FROM 2 TO 5 AMINO GROUPS, AND A PARTICULATE CARRIER OR LIQUID MEDIUM FOR THE POLYAMIDE, WHICH IS A DETERGENT BUILDER OR FILLER, OR IS AN AQUEOUS MEDIUM CONTAINING A NONIONIC SURFACE ACTIVE AGENT. IN SOME INSTANCES BENTONITES MAY BE INCLUDED IN THE PARTICULATE COMPOSITIONS TO SOFTEN THE FABRICS THAT ARE WASHED, AND TERTIARY AMINES MAY BE FORMULATED INTO THE LIQUID COMPOSITIONS TO INCREASE FABRIC SOFTENING ACTION. DESPITE THE FACT THAT THE CONDITIONING COMPOSITION IS ADDED TO THE WASH WATER IN THE WASH CYCLE OF THE AUTOMATIC WASHING MACHINE, THE ANTISTATIC POLYAMIDE THEREOF DOES NOT REACT ADVERSELY WITH ANIONIC DETERGENTS IN THE WASH WATER (UNLIKE QUATERNARY AMMONIUM HALIDE ANTISTATIC AGENTS), SO THE CLEANING POWER AND OTHER DESIRABLE PROPERTIES OF THE DETERGENT COMPOSITION THAT IS IN THE WASH WATER ARE NOT COMPROMISED, EVEN WHEN THE DETERGENT COMPOSITION EMPLOYED IS BASED ON ANANIONIC DETERGENT OR CONTAINS ANIONIC COMPONENTS. ALSO WITHIN THE INVENTION ARE A PROCESS FOR MANUFACTURING PARTICULATE WASH CYCLE ADDITIVE ANTISTATIC COMPOSITIONS AND A METHOD OF USING THE COMPOSITIONS DESCRIBED.
