The present application is directed to water and surfactant-containing liquid washing or cleaning agents containing a hydrophobic precursor compound in microemulsified form, from which a peroxycarboxylic acid or the salt thereof can be released by UV radiation. Methods for washing textiles and cleaning hard surfaces using such precursor compounds are also included.

Detergent composition

A detergent composition comprising a subtilisin variant having the amino acid sequence set forth in SEQ ID NO: 1, and at least one additional ingredient selected from i) bleaches selected from percarbonates, persulphates and organic peracids, ii) aminocarboxylates, or iii) sulphonated polymers, or iv) organophosphoric acids or salts thereof and mixtures thereof is provided. Also provided is a detergent composition comprising a subtilisin variant having the amino acid sequence set forth in SEQ ID NO: 1, wherein the detergent composition is at least partially enveloped in a water soluble or water dispersible package. The compositions exhibit good performance on proteinaceous stains, even when formulated at alkaline pHs. A method of removing proteinaceous stains from surfaces comprising such stains is also provided.

Sulfoperoxycarboxylic acids, their preparation and methods of use as bleaching and antimicrobial agents

The present invention relates to novel sulfoperoxycarboxylic acid compounds, and methods for making and using them. The sulfoperoxycarboxylic compounds of the invention are storage stable, water soluble and have low to no odor. Further, the compounds of the present invention can be formed from non-petroleum based renewable materials. The compounds of the present invention can be used as antimicrobials, and bleaching agents. The compounds of the present invention are also suitable for use as coupling agents.

Method of washing textile articles

The present invention relates to a method of washing textile articles that can be carried out, for example, in a continuous batch tunnel washer. Embodiments of the present method can include treating the textile with an aqueous composition including cleaning agent and halogen-containing bleaching agent for a time sufficient to remove soil from the textile and contacting the halogen-treated textile with an aqueous composition including a peroxycarboxylic acid. The concentration of halogen after the sufficient time can be at a level that does not result in adverse interaction between the halogen-containing bleaching agent and the peroxycarboxylic acid. Embodiments of the present method can clean textiles with the results of more effective stain removal and less waste through destruction of the textile article. Further, the present invention can clean a textile contacted soiled by a composition including chlorhexidine gluconate without resulting staining of the textile, which staining could have been permanent.
