  • Patent number: 6268332
    Abstract: The present invention relates to rinse-added fabric softening compositions, including translucent or clear liquid compositions. The compositions of the present invention comprise a polyoxyalkylene alkyl amide surface active agent which provides increased softness to fabrics, increased stability and formulatability to dispersed phase liquids, and provide for a reduced level of principal solvent when formulated into translucent or clear liquid compositions. In the most basic form, the compositions of the present invention comprise: a) from about 1% to about 80% by weight, of a fabric softening active; b) less than about 15% by weight, of a principal solvent, said principal solvent having a ClogP of from about 0.15 to about 1; c) from about 0.5% to about 10% by weight, of a polyoxyalkylene alkyl amide surface active agent; and d) the balance carriers and adjunct ingredients.

  • Patent number: 6239087
    Abstract: Detergent compositions containing certain acetals or ketals which hydrolyze upon exposure of surfaces washed in solution of said compositions to a reduction in pH, thereby releasing a fragrance which is characteristic of one or more of the hydrolysis products. The acetals and ketals themselves also form part of the invention; they have a molecular weight of at least about 350; a ClogP of about 4, and a half-life of less than 60 minutes when measured at pH=0 by the pro-fragrant hydrolysis test.
