  • Publication number: 20260132356
    Abstract: The invention is directed to a stable composition wash composition. The wash composition comprises a mixture of biodegradable thickeners having starch and cellulose. The wash composition is mild at a pH of 4.2 or under, has a viscosity of 40,000 cps or less, and surprisingly, is free of syneresis, discoloration and malodor, even after being stored at elevated temperatures.

  • Patent number: 12533305
    Abstract: The present invention is directed to a naturally derived surfactant system and an end use composition comprising the surfactant system. The naturally derived surfactant system comprises an anionic and nonionic surfactant comprising polyglycerol ester that is stable in an end use composition having a pH from 4.8 to 6.5. Such end use compositions are mild, have excellent lathering characteristics, and do not require glycinates, polyglycosides, betaines, sultaines and sulfates.

  • Publication number: 20250381123
    Abstract: A wash composition comprising: a) anionic surfactant; b) amphoteric surfactant, zwitterionic surfactant or both; c) 0 to 4% by weight nonionic surfactant; and 1.7 to 8.5% by weight thickener, the thickener having starch and cellulose, the starch being a hydroxypropyl starch, distarch phosphate or mixture thereof and the cellulose being a microcrystalline cellulose selected from the group consisting of carboxymethylcellulose, hydroxymethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose or a mixture thereof, wherein when the thickener is present at 1.7 to less than or equal to 4.5% by weight of the composition, the weight ratio of starch:cellulose is greater than 0 and less than 4.5, and further wherein when the thickener is present at greater than 4.5% to 8.5% by weight, the weight ratio of starch:cellulose is >0 and less than 15, and: i) the composition has from 3.

  • Publication number: 20250381124
    Abstract: The invention is directed to a stable composition wash composition. The wash composition comprises a mixture of biodegradable thickeners and unsaturated zwitterionic surfactants. The wash composition has a stable viscosity and surprisingly, is free of syneresis, discoloration and malodor, even after being stored at elevated temperatures.

  • Publication number: 20250381113
    Abstract: The present invention is directed to a wash composition substantially free of sulfates and that comprises glutamate, aspartate or both, and optionally additional anionic surfactant selected from isethionates, taurates and/or glycinates. Total surfactant used in the wash composition is 9% and the by weight the wash composition is mild but surprisingly with displays good lather characteristics while being formulated with reduced palm kernel oil derived surfactants.
