Definitions

  • the present invention relates to built laundry detergent compositions containing anionic sulphonate or sulphate surfactants and exhibiting increased mildness to the skin.
  • Heavy duty laundry detergent compositions have for many years contained an anionic sulphonate or sulphate surfactant, for example, linear alkylbenzene sulphonate (LAS) or primary alcohol sulphate (PAS), as the principal detergent-active ingredient.
  • anionic surfactants are frequently used in conjunction with ethoxylated alcohol nonionic surfactants which give improved detergency on hydrophobic soils.
  • the nonionic surfactants generally have alkyl chain lengths of C 12 -C 18 and degrees of ethoxylation of 1 to 10.
  • anionic and anionic/nonionic surfactant systems are robust and highly efficient on a wide range of soils and under a wide range of conditions, for example, temperature and water hardness. However, they are not noted for mildness to skin. These materials are designed to interact with fatty materials like body soil and protein residues on soiled laundry, and can therefore interact with the skin to give reactions such as dryness and erythema (redness).
  • the milder surfactants used to formulate products intended for prolonged skin contact, for example, shampoos and shower gels would not perform adequately in heavy duty laundry detergent compositions because of insufficient interaction with fatty materials occurring as soil.
  • Alkylpolyglycosides have been widely disclosed in the art as environmentally friendly carbohydrate-derived nonionic surfactants, and are used in various detergent and personal care products. Disclosures in the prior art include EP 75 994A, EP 75 995A and EP 75 996A (Procter & Gamble), EP 238 638B (Staley/Henkel), EP 487 262A (Unilever), EP 495 176 (Huels), EP 374 702A (Kao), WO 92 06150 (P&G), WO 94 26861A (Henkel), WO 94 24242 (P&G) and WO 96 29977 (Henkel). The use of APGs as detergency builders has been disclosed in EP 976 817A (Henkel).
  • WO 00 08129A discloses mild particulate laundry detergent compositions based on high-foaming anionic surfactant (for example linear alkylbenzene sulphonate) plus one or more milder cosurfactants, for example, amine oxide or cocoamidopropyl betaine.
  • high-foaming anionic surfactant for example linear alkylbenzene sulphonate
  • milder cosurfactants for example, amine oxide or cocoamidopropyl betaine.
  • the present invention provides the use of a an alkylpolyglycoside in an amount of from 0.5 to 5 wt% to increase the mildness to skin of a built particulate laundry detergent composition containing an anionic sulphonate or sulphate detergent.
  • the invention is based on the observation that use of alkylpolyglycoside (APG) at low levels to replace part of a conventional anionic/nonionic surfactant system results in a measurable increase in mildness to skin.
  • APG alkylpolyglycoside

  • Preferred detergent compositions utilising the invention contain a conventional anionic sulphonate or sulphate surfactant and a conventional nonionic surfactant, and also contain as an essential ingredient a low level of alkylpolyglycoside.

  • the alkyl chain length is preferably in the C 12 to C 15 range.
