Definitions

  • TECHNICAL FIELD This invention relates to cleansing soap bars, preferably superfatted, containing cationic polymer mildness additive and some synthetic surfactant.
  • Synthetic detergents are relatively expensive. None of the synthetic products as yet matches the low cost of soap when compared on a 100% active ingredient basis.
  • This invention is an improved milled, mild personal cleansing soap-synthetic bar comprising: a mixture of soap, a cationic polymeric skin mildness aid, and a mixture of a C14-C20 alkyl polyethoxylate (20-250) nonionic detergent surfactant and a C10- 18 acyl isethionate detergent surfactant for inhibiting scum formation and maintaining good lather characteristics.
  • a mixture of soap a cationic polymeric skin mildness aid
  • a mixture of a C14-C20 alkyl polyethoxylate (20-250) nonionic detergent surfactant and a C10- 18 acyl isethionate detergent surfactant for inhibiting scum formation and maintaining good lather characteristics.
  • a milled soap-synthetic bar comprising: (1) from about 45% to about 90%, preferably from about 55% to about 90%, more preferably from about 65% to about 75% soap; (2) from about 0.5% to about 5%, preferably from about 1% to about 2% of cationic polymeric skin mildness aid; (3) from about 0.5% to about 10%, preferably from about 1% to about 8% of C ⁇ -C20 > preferably C16-C18, fatty alkyl (alcohol) polyethoxylate (from about 20 to about 250, preferably from about 25 to about 100, more preferably from about 30 to about 80 moles of ethylene oxide moieties per molecule) nonionic detergent surfactant; and (4) from about 0.5% about 10%, preferably from about 2% to about 5% of Cin-Ci ⁇ , preferably C12-C16, acyl isethionate detergent surfactant.
  • the ratio of nonionic detergent surfactant to acyl isethionate deter ⁇ gent surfactant is typically from about 1:1 to about 2:1, prefer- ably from about 1:1 to about 1.5:1.
  • the ratio of the combination of nonionic and acyl isethionate synthetic detergent surfactants to soap is from about 1:70 to about 1:2, preferably from about 1:35 to about 1:4.
  • soap-synthetic bar also “soap-synbar,” as used herein mean that the bar has more soap than synthetic surfactant unless otherwise specified.
  • percentages, ratios, and parts herein are on a weight basis, unless otherwise specified. All levels and ranges herein are approximations unless otherwise specified.
  • surfactant mildness can be measured by a skin barrier destruction test which is used to assess the irri- tancy potential of surfactants. In this test the milder the surfactant, the less of the skin barrier is destroyed. Skin barrier destruction is measured by the relative amount of radio- labeled water ( H-H20) which passes from the test solution through the skin epidermis into the physiological buffer contained in the diffusate chamber. This test is described by T.J. Franz in the J. Invest. Dermatol.. 1975, 64, pp. 190-195; and in U.S. Pat. No. 4,673,525, Small et al . , issued June 16, 1987, incorporated herein by reference. Barrier destruction testing shows that the bars of this application are mild. (1) Soap

Abstract

Des barres de savon doux contenant de faibles niveaux d'additifs de douceur polymères cationiques présentant une faible quantité de tensio-actif détergent non ionique fortement hétoxylé afin de réduire la formation de mousse présentent des caractéristiques moussantes réduites. L'addition d'une faible quantité de tensio-actif détergent doux, tel que l'acyl iséthionate, améliore la mousse sans affecter négativement d'autres propriétés de la barre.
