Liquid enzyme composition with sulfite scavenger

A multi-compartment water-soluble unit dose detergent article, comprising:

• (a) a first compartment consisting of the liquid enzyme composition, and
• (b) a second compartment comprising a salt of sulfite, bisulfite or metabisulfite, and one or more detergent ingredients selected from surfactants, builders, dye transfer inhibiting agents, dispersants, anti-redeposition agents, suds suppressors, hueing dyes, aesthetic dyes, opacifiers, perfumes, structurants, hydrotropes, pigments and mixtures thereof;
• wherein the first and second compartments are adjacent, and each is surrounded by water-soluble film;
• wherein the liquid enzyme composition comprises:
• 0.01-25% w/w of active enzyme protein, and
• 0.05-30% w/w of a sulfite scavenger or 0.05-30% w/w of a sulfite radical scavenger;
• wherein the sulfite scavenger is a compound having a redox potential of 0.1-0.6V vs SHE, or is an aldehyde or ketone forming covalent bonds with sulfite, bisulfite or metabisulfite;
• and
• wherein the sulfite radical scavenger can react with the sulfur trioxide radical anion and undergo one electron reduction.
