Definitions

  • the present invention relates to a soap composition, and in particular to a transparent or translucent soap composition.
  • soap compositions used to make soap bars or tablets, particularly toilet soap tablets for personal washing, are known in the art.
  • properties of the soap composition or soap tablet such as ability to lather, hardness, reduction in mush (softening when left standing in water), feel and moisturisation. It can be difficult to obtain a soap composition having all or most of the aforementioned properties.
  • Soap compositions can be either opaque, translucent or transparent, and it can be particularly difficult to achieve the aforementioned properties whilst maintaining or improving the translucency or transparency of a soap composition.
  • GB-1417183 and GB-1487552 both disclose detergent bars containing a water soluble lactate salt, which together with a water soluble glutamate salt, act as moisturising components.
  • US-4297230 is directed to a transparent soap bar containing potassium soap and chloride anions.
  • W0 99/42554 is directed to a soap bar containing 30-60% by weight of alkali metal salt of a defined fatty acid mixture, 3-35% by weight of fatty acid, 2-25% by weight of structurant and the remainder water.
  • the present invention provides a soap composition
  • a soap composition comprising (i) 50 to 90% by weight of alkali metal soap of C 8 -C 2 fatty acids, (ii) 3 to 25% by weight of at least one polyol, (iii) 0.1 to 10% by weight of the potassium salt of a carboxylic acid and/or hydroxy carboxylic acid having 6 or less carbon atoms, and (iv) 5 to 25% by weight of water.
