Washing or cleaning agents may include at least one protease and at least one stabilizer compound. The protease(s) may have an amino acid sequence with at least 70% sequence identity with the amino acid sequence specified in SEQ ID NO:1 over the entire length thereof and has an amino acid substitution at at least one of the positions corresponding to the positions 12, 43, 122, 127, 154, 156, 160, 211, or 222, in each case based on the numbering according to SEQ ID NO:1. The stabilizer compound(s) may be selected from the group consisting of a phenylboronic acid derivative, boric acid, a peptide inhibitor, and combinations thereof.

The present invention relates to a composite form of tetraacetylethylenediamine (TAED) and a method for its preparation. The composite form may comprise a new crystalline form. The invention also relates to the crystalline form itself. The present invention also relates to compositions comprising tetraacetylethylenediamine in these forms.

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.

The invention relates to a method of automatic dishwashing, comprising: placing soiled wares inside a cleaning volume; providing a first cleaning composition comprising a bleach and a second cleaning composition different from the first composition; and delivering the first composition and the second composition separately to the cleaning volume to contact the soiled wares, wherein: the first composition is delivered to the cleaning volume as a mist and the second composition is delivered to the cleaning volume as a jet; and the first and second compositions are delivered to the cleaning volume at a temperature below 100° C. The invention also relates to a dishwasher and a kit for use in the inventive method.

The disclosure provides a silica-based scale cleaning technology. The disclosure can provide a cleaning agent of a silica-based scale, containing a silicic acid compound. The disclosure can also provide a cleaning method of a water treatment apparatus, including: using a solution containing a silicic acid compound. Further, the disclosure can provide a cleaning method of a silica-based scale, including: using an agent containing a silicic acid compound for a water system.

A peroxide delivery system is produced. The peroxide delivery system includes a dry powder that releases the peroxide quickly and completely when needed. The peroxide delivery system may be produced by combining a liquid peroxide or peroxide solution with an inorganic solid support that is inert to the peroxide and is capable of adsorbing large amounts of the liquid peroxide or peroxide solution while remaining dry to the touch. Methods of combining the inorganic solid support with the liquid peroxide or peroxide solution are disclosed. The peroxide delivery system can be formulated in preparations of powders, liquids, foams, sprays, gels, ointments, creams, sticks, or pastes that can be utilized in a variety of applications such as cleaning, stain removal and antiseptic products, for example.

The present invention concerns a composition comprising manganese containing catalyst salts, a water-soluble polymer and a polysaccharide absorbent. The invention also concerns a method of making such compositions, preferably in the form of a granule, and bleaching formulations comprising the salt and a peroxy compound or precursor thereof. The catalyst salt containing composition and formulations comprising it, are suitable for use in catalysing oxidation, for example as a component of a laundry or dishwasher bleaching composition. The invention further relates to cleaning agents comprising the compositions described herein.

The invention relates to methods for cleaning a medical device, a medical cleaning composition, use of a polypeptide having DNase activity for cleaning a medical device, and a medical device coated with a polypeptide having DNase activity.
