  • Publication number: 20060272360
    Abstract: A non-intrusive device for automatically dispensing at least one liquid laundry care composition to an automatic laundry washing machine. The device employs a Venturi tube mechanism or a pump to dose the laundry detergent care composition. The dosing is either manually controlled or controlled by a machine-generic algorithm capable of determining the actual cycle at any duration of wash for various cycle designs from various washing machines, without the input of precise cycle design; and dose the correct products correctly and is capable of distinguishing between major water addition and a water pulse.

  • Publication number: 20040248749
    Abstract: The invention relates to a cleansing composition product having at least one acid phase and at least one soap phase that are separated. The inventive composition is contained in a partitioned container in one embodiment and a partitionless container in another embodiment. This multiphase composition is stable upon storage and in a further embodiment is dispensed as a striped product where typically lather is reduced upon blending and a fatty acid is deposited onto the skin.

  • Patent number: 6809070
    Abstract: Mild toilet bar compositions are described that contain harsh to the skin cleansing components, such as soap, and a latent acidifier. The latent acidifier reduces the pH of the toilet bar when used for cleansing but does not substantially affect the hardness of the toilet bar. Lather, drag properties, and deposition of benefit agents are substantially improved.

  • Patent number: 6426326
    Abstract: The invention relates to liquid cleansing compositions in lattellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. However, these liquids often undergo an irreversible decrease in viscosity under freeze/thaw conditions, losing their moisturization signals. The use of low salt levels in amphoteric and anionic surfactants in a structured liquid product has been found to improve its freeze/thaw stability.

  • Patent number: 6399045
    Abstract: The present invention teaches liquid sunscreen compositions in which level of surfactant is higher than level at which the sunscreen component(s) are still soluble in the surfactant in which they are used; and which comprise minimal levels of cationic polymer. Combination of cationic polymer (especially preferred surfactants and at minimum levels) and minimal levels of sunscreen lead to compositions with minimal levels of deposition and minimal SPF. Further, the compositions also maintain good lather.
