  • Publication number: 20090093394
    Abstract: A fabric softening composition comprising from 1 to 80% by weight of ester-linked quaternary ammonium fabric softening material comprising a quaternised mixture of mono- di- and tri-ester of alkanolamine in which the tri-ester content of said mixture is from 25 to 50% by weight of said mixture, wherein: (i) when the tri-ester content is from 25 to 30% by weight of said mixture the free amine content of the composition is less than 0.5% by weight on the weight of said mixture, (ii) when the tri-ester content is more than 30% by weight of said mixture the free amine content of the composition is less than 6% by weight based on the weight of said mixture, the composition containing less than 1% by weight of free fatty acid based on said mixture.

  • Publication number: 20050153853
    Abstract: A composition suitable for use in personal cleaning or detergent soap bars, which includes a sulfonated fatty acid or alpha sulfonated alkyl ester and a secondary synthetic surfactant, and methods for producing such a composition. The composition and methods exhibit efficient processing and allow for formation of cleansing or detergent bars with improved hardness, improved resistance to marring and improved processability, lowered wear-rate and decreased mush formation during consumer use.

  • Patent number: 6906025
    Abstract: Disclosed are automatic dryer added fabric conditioning articles and methods utilizing fabric conditioning compositions comprising from about 20 percent to about 80 percent by weight of a mixture of quaternary ammonium compounds, and between about 80 percent to about 20 percent by weight of a mixture of glycerin and glyceryl esters, wherein the fabric conditioning compositions possess a melting point of about 30° C. to about 65° C. The conditioning compositions of the present invention are preferably employed in combination with a dispensing means adapted for use in an automatic clothes dryer. The fabric conditioning compositions may be coated onto substrates, and the fabric conditioning articles thereby obtained used to impart softness and anti-static properties to fabric. The method portion of the invention involves the commingling of damp fabrics with the fabric conditioning compositions in an automatic clothes dryer to impart softness and anti-static properties to the fabric.

  • Publication number: 20050124515
    Abstract: Disclosed are improved cleaning compositions comprising soap&com ma; fatty acid, synthetic detersive surfactant, salt and a polyhydridic alcohol, which are suitable for formation into precursor cleansing/laundry bar “soap noodles,” personal cleansing bars and laundry detergent bars. The compositions comprise: (a) from about 58% to about 93% by weight of an approximately 70% aqueous soap slurry; (b) from about 1% to about 15% by weight of a fatty acid; (c) from about 2% to about 30% by weight of an approximately 55% aqueous mixture of anionic surfactants comprising i) an alpha sulfonated alkyl ester, and ii) a sulfonated fatty acid or salts thereof, wherein the ratio of i) to ii) is from about 10:1 to about 1:10; (d) from about 0.5% to about 2% by weight of a salt; (e) from about 0.

  • Publication number: 20050044638
    Abstract: Disclosed are automatic dryer added fabric conditioning articles and methods utilizing fabric conditioning compositions comprising from about 20 percent to about 80 percent by weight of a mixture of quaternary ammonium compounds, and between about 80 percent to about 20 percent by weight of a mixture of glycerin and glyceryl esters, wherein the fabric conditioning compositions possess a melting point of about 30° C. to about 65° C. The conditioning compositions of the present invention are preferably employed in combination with a dispensing means adapted for use in an automatic clothes dryer. The fabric conditioning compositions may be coated onto substrates, and the fabric conditioning articles thereby obtained used to impart softness and anti-static properties to fabric. The method portion of the invention involves the commingling of damp fabrics with the fabric conditioning compositions in an automatic clothes dryer to impart softness and anti-static properties to the fabric.
