  • Patent number: 5026400
    Abstract: Narrow range ethoxylate nonionic detergents, in combination with coil release promoting polyethylene terephthalate-polyoxyethylene terephthalate (PET-POET) copolymer (in place of broad range ethoxylate nonionic detergent and PET-POET copolymer) are of significantly and unexpectedly improved soil release promoting activity in built synthetic organic detergent compositions, of either the phosphate-built or non-phosphate-built types. Preferably, there will be present with the PET-POET copolymer a stabilizing proportion of polyacrylate, to stabilize the PET-POET copolymer against deterioration and loss of soil release promoting activity on storage at elevated temperature, especially when in contact with alkaline components of the detergent composition. The improved soil release promoting activity is most pronounced when the laundry to be washed and treated is subjected to repeated launderings with the invented compositions in cold water and when it includes polyester-containing fibrous materials.
    Type: Grant
    Filed: December 4, 1989
    Date of Patent: June 25, 1991
    Assignee: Colgate-Palmolive Company

  • Patent number: 4806261
    Abstract: A detersive article, useful for charging an automatic washing machine with particulate built synthetic organic detergent composition, includes a detersive charge of such particulate composition in a closed container or packet which is formed by sealing about such composition a sheet or sheets of readily water dispersible water soluble cellulose compound and cellulose fibers, which is coated and/or covered or laminated with water soluble polyvinyl alcohol on interior surfaces thereof. The packet material dissolves or disperses rapidly when the packet is added to wash water in an automatic washing machine, and thereby releases contained detergent composition to the wash water earlier in the washing process than do other "dissolvable packets" which are made of polyvinyl alcohol.
