  • Patent number: 8703108
    Abstract: Cleansing compositions include a mixture of alkyl ether carboxylic acids and/or salts thereof, each having a structure according to formula (1): R1—O—(CH2CH2O)n—CH2—COOM??(1) where R1 is an alkyl group having 4 to 22 carbon atoms, n is a number of from 0 to 20, and M is a hydrogen atom, alkali metal, alkaline earth metal, ammonium, or organic ammonium. The mixture includes alkyl ether carboxylic acids and/or salts having at least two different alkyl groups R1, an average carbon number of alkyl groups R1 of alkyl ether carboxylic acids and/or salts in the mixture is from 10.8 to 12.

  • Patent number: 7582592
    Abstract: A skin cleansing composition contains, in addition to water, the following ingredients (A) to (D): (A) a polyoxyethylene alkylether sulfate, (B) an ether carboxylic acid-type surfactant, (C) an alkyl polyglycoside, and (D) one or more of a higher fatty acid and a higher alcohol. A total amount of the ingredients (A), (B) and (C) ranges from 5 to 30 wt % based on the whole composition, with the ingredient (A) amounting to from 20 to 80 wt %, the ingredient (B) amounting to from 7 to 70 wt %, and the ingredient (C) amounting to from 7 to 70 wt %, the amount of the ingredient (D) ranges from 0.3 to 3 wt % based on the whole composition. A pH of the composition ranges from 4.5 to 7 when diluted to 5 wt % by weight with deionized water. The skin cleansing composition can produce abundant foam of fine and smooth quality without an increase in foam viscosity, and therefore, allows the body to be washed with comfort.
