    • The present invention relates to cleaning compositions comprising a protease variant. One cleaning composition comprises a protease variant including a substitution of an amino acid residue with another naturally occurring amino acid residue at an amino acid residue position corresponding to position 103 of Bacillus amyloliquefaciens subtilisin in combination with a substitution of an amino acid residue with another naturally occurring amino acid residue at one or more amino acid residue positions corresponding to positions 1, 3, 4, 8, 9, 10, 12, 13, 16, 17, 18, 19, 20, 21, 22, 24, 27, 33, 37, 38, 42, 43, 48, 55, 57, 58, 61, 62, 68, 72, 75, 76, 77, 78, 79, 86, 87, 89, 97, 98, 99, 101, 102, 104, 106, 107, 109, 111, 114, 116, 117, 119, 121, 123, 126, 128, 130, 131, 133, 134, 137, 140, 141, 142, 146, 147, 158, 159, 160, 166, 167, 170, 173, 174, 177, 181, 182, 183, 184, 185, 188, 192, 194, 198, 203, 204, 205, 206, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 222, 224, 227, 228, 230, 232, 236, 237, 238, 240, 242, 243, 244, 245, 246, 247, 248, 249, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 265, 268, 269, 270, 271, 272, 274 and 275 of Bacillus amyloliquefaciens subtilisin; wherein when said protease variant includes a substitution of amino acid residues at positions corresponding to positions 103 and 76, there is also a subtitution of an amino acid residue at one or more amino acid residue positions other than amino acid residue positions corresponding to positions 27, 99, 101, 104, 107, 109, 123, 128, 166, 204, 206, 210, 216, 217, 218, 222, 260, 265 or 274 of Bacillus amyloliquefaciens subtilisin; and one or more cleaning adjunct materials. Another cleaning composition comprises a protease variant including a substitution of an amino acid residue with another naturally occurring amino acid residue at one or more amino acid residue positions corresponding to positions 62, 212, 230, 232, 252 and 257 of Bacillus amyloliquefaciens subtilisin; and one or more cleaning adjunct materials.

    • The present invention provides a product and method for cleaning or laundering or treatment of fabrics or surfaces, with a liquid cleaning, laundering or treating composition having improved enzyme stability in the presence of an oxidant comprising a) at least one cross-linked hydrolase crystal, or mixture of hydrolase crystals; b) an oxidant, or source of hydrogen peroxide; and c) at least one cleaning, laundering or treating additive, other than an oxidant, wherein the improved stability is due to one or more of the following: (i) where c) includes a surfactant, maintaining the upper limit thereof to no greater than 10% by weight of the composition; (ii) maintaining the pH of the liquid composition between 5 and 8; and (iii) where c) includes surfactants, no more than 20% of the total surfactants is anionic. The use of the cross-linked hydrolase crystals results in compositions which have surprisingly proficient retained hydrolytic stability in the presence of such oxidant versus a commercially available non-cross-linked enzyme.
