Definitions

  • This invention relates to aqueous alkaline isotropic liquid detergent compositions particularly to concentrated compositions containing hydrogen peroxide and a surfactant system including an anionic surfactant.

  • the composition may also contain a hydrotrope.

  • Example 1 uses a mixture of ammonium xylene sulphonate (4%) and ethanol (5.5%) .
  • the level of peroxide is only 0.18% and the pH is 7.1 in this and the other examples in this patent specification. All examples are rich in anionic surfactant.
  • US 4 507 219 describes heavy duty liquid detergents in the form of isotropic liquids.
  • a chlorine bleach can be added and the compositions are stated to be compatible with the bleach.

  • the compositions may contain a phase regulator such as ethanol, n-propanol, isopropanol, butanol, propane-1,2-diol, propane-l,3-diol, n-hexanol; 2-methyl,2,4- pentanediol, monomethyl-, ethyl and propyl and monobutyl- ethers and di-ethylene glycol.

  • a concentrated peroxide liquid is desirable because of the obvious reduction in transport and storage costs.

Inclusion of peroxide can destabilise an otherwise stable liquid formulation and there is therefore no guarantee of success if one simply takes a known concentrated liquid detergent formulation and adds peroxide.

Abstract

L'invention a pour objet une composition de détergent liquide isotropique alcaline aqueuse concentrée. Cette composition comprend un mélange d'un agent tensio-actif non ionique et d'un agent tensio-actif anionique, avec un hydrotrope et du peroxyde d'hydrogène dissous. La formulation comprend plus de 40% d'un agent tensio-actif, au total, lorsque celui-ci est fortement non anioique, ou plus de 30 % d'un agent tensio-actif anionique lorsque celui-ci est fortement anionique. Les compositions riches en agents anioniques peuvent comprendre des adjuvants ou être dépourvues d'adjuvants. Ces compositions sont, de préférence, sensiblement dépourvues d'éthanol ou d'autres monoalcools C1-4 pour réduire le risque d'explosion d'un mélange de peroxyde et d'alcool à faible point d'inflammabilité. Les compositions décrites peuvent être utilisées comme détergents de blanchissage et présentent l'avantage d'une faible dérive du pH tout en maintenant de forts niveaux de peroxyde sur une longue période.
