  • Patent number: 8778910
    Abstract: The invention relates to concentrated liquid cleansing compositions in lamellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. The use of a specific ratio of synthetic anionic surfactant(s) and co-surfactant(s) to fatty acid(s) in a structured liquid product was found to improve lather production by moderating or eliminating the increase in viscosity upon dilution. In a further embodiment, specific small hydrophobic molecules were found to improve freeze/thaw stability and thereby cause the inventive composition to maintain noticeable moisturization signals.

  • Patent number: 8114826
    Abstract: A flowable concentrated soap cleansing composition is provided which includes from 40 to 65% of C12-C18 fatty acid mixture in combined amount of salt and free acid forms, the mixture having C12-C14 chain length present in greater amount than C16-C18 chain length of fatty acid. Further, the composition includes 25 to 50% water, 1 to 15% of a first anti-crystallization agent, and 2 to 15% of a second anti-crystallization agent. The first anti-crystallization agent is sodium lauryl ether sulfate with a weight average ethoxylation of from 0.5 to 2 moles ethylene oxide per mole of sulfate. The second anti-crystallization agent is polypropylene glycol of weight average molecular weight ranging from 195 to 10,000. The composition has a viscosity ranging from 10 to 100 Pa*s at 20° C. as measured after 2 minutes at 10 rpm on a Brookfield Viscometer using Spindle RV 7.

  • Patent number: 8114824
    Abstract: The present invention relates to novel composition containing specific mild surfactant system comprising fatty acyl isethionate product and alkanoyl surfactant. Addition of triglyceride of specific degree of hydrogenation permits the retention of emollient benefit while retaining also “squeaky” feel of soap and maintaining lather stability.
