  • Stable multiple emulsion composition
    Patent number: 6290943
    Abstract: W1-O-W2 emulsions are disclosed in which the W1/O emulsion comprises an internal aqueous phase containing a benefit agent and an oil phase surrounding it, and, around this is found an external isotropic aqueous phase. It is critical that the external surfactant phase not comprise an amido containing anionic. It is also critical that oil be not greater than 50% unsaturated and not be a volatile silicone.
    Type: Grant
    Filed: October 22, 1999
    Date of Patent: September 18, 2001
    Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.
    Inventors: Mark Stephen Naser, Tirucherai Vasudevan
  • Dual chamber cleansing system, comprising multiple emulsion
    Patent number: 6268322
    Abstract: The invention provides an at least dual compartment container containing at least one surfactant stripe and at least one multiple emulsion stripe. By dispensing a multiple emulsion stripe, greater deposition, particularly deposition of water soluble benefit agent (e.g., glycolic acid) is achieved than believed possible.

  • Phase stable multiple emulsion compositions
    Patent number: 6235298
    Abstract: W1-O-W2 emulsions are disclosed in which the W1/O emulsion comprises an internal aqueous phase containing optional benefit agent and an oil phase surrounding it, and, around this is found an external isotropic aqueous phase comprising surfactant system and specific thickeners. Selection of surfactant system and thickener is critical to the multiple emulsion composition not phase separating.

  • Aqueous liquid compositions comprising peracid compounds and substituted phenolic compounds
    Patent number: 5712239
    Abstract: The present invention relates to liquid detergent compositions comprising:(1) 1-80% by wt. surfactant;(2) defined peroxyacid; and(3) 0.01-20% by wt. of a mono substituted phenolic compound.The compounds help to extend the half life of the peracid bleaches in such compositions. The invention further relates to a method of incorporating stability of surfactant compositions comprising peracid bleaches which method comprises adding 0.01-2.0% by wt. of said substituted phenolic compound to the composition.
    Type: Grant

  • Aqueous liquid compositions comprising peracid compounds and defined N-oxide compounds
    Patent number: 5674828
    Abstract: The present invention relates to liquid detergent compositions comprising:(1) 1-80% by wt. surfactant;(2) defined peroxyacid; and(3) 0.01-20% by wt. of N-oxide compound.The N-oxide compounds help to extend the half life of the peracid bleaches in such compositions. The invention further relates to a method of incorporating stability of surfactant compositions comprising peracid bleaches which method comprises adding 0.01-2.0% by wt. of said N-oxide compound to the composition.
