The invention refers to a liquid detergent concentrate composition comprising an emulsion having a water phase and an oil phase, the composition comprising based on the whole concentrate: (A) 1-50 wt.-% of a source of alkalinity; (B) 1-70 wt.-% of a at least one non-ionic surfactant; (C) 0.1-10 wt.-% of a copolymer of (1) at least one monomer of the formula (I): HC&#x2550;C(R)&#x2014;COOH, wherein Ris a linear or branched C-Calkyl or phenyl group; and (2) at least one monomer of (meth)acrylic acid (C-C) alkyl or phenyl ester; (D) 0.1-10 wt.-% of a copolymer of (i) acrylic and/or methacrylic acid; (ii) at least one monomer of the formula (III): HC&#x2550;C(R)&#x2014;C(O)&#x2014;O&#x2014;(CHCHO)&#x2014;R, wherein Ris H or CH, n is at least 2 and preferably has an average value of at least 10, preferably 10 to 70, 10 to 60, 10 to 30, and R4 is a hydrophobic group containing 8 to 24 carbon atoms; and (iii) at least one monomer of C-Calkyl (meth)acrylate.

Liquid detergent composition

The present disclosure provides methods for generating percarboxylic acid compositions and/or peroxycarboxylic acid compositions formed external to a point of use in non-equilibrium reactions for use in certain bleaching and antimicrobial applications, in particular laundry applications. The compositions are generated external to a point of use, at alkaline pH levels, viz. greater than about pH 12, and optionally suitable for use with detergents and/or surfactants for synergistic bleaching efficacy. Methods of bleaching and/or disinfecting are further provided.
