  • Patent number: 10570354
    Abstract: The present invention relates to fabric softener active compositions comprising a combination of a mixture of quarternary ester ammonium compounds and fatty solvents (a fatty acid ester, a fatty acid, a fatty alcohol and mixtures thereof) and methods of making and using the same. The fabric softener active compositions preferably comprise component (a), said component being a mixture of quarternary ester ammonium compounds obtained by esterification of a mixture of alkanolamines comprises at least a trialkanolamine and a monoalkyldialkanolamine; component (b), said component being a fatty acid ester or a mixture of fatty acid esters, wherein the component (b) content is in the range from 5 to 60% wt. based on the total weight of the fabric softener active composition; and a component (c), said component being a fatty acid or a mixture of fatty acids, wherein the component (c) content is in the range from 0 to 15% wt. based on the total weight of the fabric softener active composition.

  • Patent number: 6890895
    Abstract: A description is given of novel aqueous compositions that soften and condition textiles and other natural and synthetic fibres, which compositions contain surfactants of a non-ionic character and cationic surfactants or esterquats obtained from alkanolamine esters based on the esterification reaction of optionally alkoxylated alkanolamines with dicarboxylic acids and fatty alcohols which are optionally alkoxylated. The mentioned cationic surfactants and esterquats improve the conditioning and softening efficiency of non-ionic surfactants on natural and synthetic fibres so that the softening compositions obtained exhibit a high degree of efficiency in the treatment of fibres, such as textiles, paper and hair, and also facilitate ironing in the case of textile fibres and combing in the case of natural fibres.

  • Patent number: 6683033
    Abstract: A concentrated aqueous betaine surfactant composition consisting essentially of a betaine compound and from 0.5 to 3.5 wt %, based on the total weight of the composition, of at least one fluidizing additive selected from the group consisting of (i) a fatty acid dimer composition and (ii) phosphoric esters of fatty alcohols or polyethoxylated fatty alcohols, the composition containing a solid content of at least 40 wt %, said composition having a reduced viscosity and a low gel point.
