A method of protecting sensitive or reactive adjuncts, preferably of the type incorporated in detergent compositions, by dissolving said adjunct in a biopolymer, thereby forming a stable particulate adjunct product comprising a molecular solid solution of adjunct in a biopolymer. Preferred adjuncts to be protected include bleach catalysts, bleach catalyst precursors, bleach precursors, enzymes, fluorescers, germicides, perfumes, anti-dye transfer and anti-dye damage agents and effervescent agents. The protected adjunct is especially useful for incorporation in non-aqueous liquid detergent compositions.
