  • High foaming nonionic surfactant based liquid detergent
    Patent number: 5610127
    Abstract: A high foaming light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising a water soluble nonionic surfactant as the major active ingredient, a supplemental amount of a water soluble, foaming, alkyl ethoxylated ether sulfate anionic surfactant, an alkyl sulfate surfactant, and a water soluble, foaming zwitterionic betaine surfactant and the balance being water.

  • Concentrated aqueous liquid detergent compositions containing deflocculating polymers
    Patent number: 5602092
    Abstract: Concentrated, structured liquid detergent compositions in the form of lamellar surfactant droplets dispersed in an aqueous electrolytic continuous phase comprises a mixture of:a) from about 10 to 45% by weight of surfactant;b) at least one detergent builder;c) from about 0.01 to about 5% by weight of a deflocculating polymer composition containing polymer chains of the structure P-QR, wherein P represents a polymer chain segment of a hydrophilic polymer, and QR represents a hydrophobic end-cap group wherein R is an organic hydrophobic radical containing from about 4 to 28 carbon atoms, and Q is selected from the group consisting of O, S, SO, SO.sub.

  • High foaming nonionic surfactant based liquid detergent
    Patent number: 5385696
    Abstract: A high foaming, nonionic surfactant based, light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising three essential surfactants: a water soluble nonionic surfactant as the major active ingredient, in an amount in excess of 50% by weight of the total surfactant content; a supplemental amount of a water soluble, foaming, anionic surfactant excluding the ethoxylated alkyl ether sulfates; and a lesser amount of a water soluble, foaming zwitterionic betaine surfactant.
