Definitions

  • the invention relates to a synergistic composition of soap/detergent bars for personal and/or fabric washing. It also relates to a process for the preparation of such soap/detergent bars for personal and/or fabric washing. In particular, the invention is directed towards the suppression of efflorescence in detergent bars comprising a detergent active and one or more phosphates.
  • Conventional detergent bars for personal and fabric washing usually contain a detergent active, water and other ingredients such as colour, perfume, preservatives, etc.
  • Structurants and fillers are also present in such compositions, which replace some of the active in the bar while retaining the desired hardness of the bar.
  • a few known structurants and fillers include starch, kaolin, silicates and talc.
  • Bars meant for personal wash are based on soap, and are either milled or non-milled.
  • Hard non-milled soap bars typically contain 20-35% moisture, while milled bars typically have a moisture content of 8-15%.
  • Unstructured hard non-milled soap bars will usually have a total fatty matter (TFM) of 55-60%, whilst unstructured milled soap bars typically have a TFM of 75-80%.
  • TFM total fatty matter
  • Reduction in TFM requires that the bar be 'structured' by the use of insoluble particulate materials like kaolin and talc and/or soluble silicates .
  • Orthophosphates and pyrophosphates are used in soap bar compositions. The phosphates help in reducing TFM, increasing the moisture content of the bar, and also act as builders. While it is advantageous to incorporate phosphates, their use in the soap system creates problems like efflorescence that impairs the visual appearance of the bar.
  • US 6310016 (Unilever Home & Personal Care USA) discloses a low total fatty matter detergent bar composition comprising 15-70% total fatty matter, 0.5-40% colloidal aluminium hydroxide-phosphate complex and 10-50% water wherein the phosphate is generated from orthophosphoric acid.
  • Electrolytes suitable for the invention include simple and condensed potassium phosphates as well as electrolytes chosen from sodium and/or potassium citrates, acetates, formates and tartarates .
  • soap bars containing phosphates have a higher pH than conventional soap bars.
  • the high pH causes problems like skin irritation and dryness, particularly amongst users with sensitive skin.
  • the pH is conventionally adjusted by adding free fatty acid.
  • These "superfatted” phosphate structured bars show enhanced efflorescence.
  • “superfatted” is meant bars that contain free fatty acid. The aforesaid problem is also not addressed in the prior art .
  • a detergent bar comprising the detergent active, phosphates and a water soluble organic salt shows synergistic benefits of minimal or no efflorescence during storage.
