摘要： A polyacid polyanhydride is used as a bleach activator especially for improving low temperature bleaching performance of peroxygen bleaches such as hydrogen peroxide or sodium perborate, in laundry and other detergent formulations. The polyanhydrides are preferably made from polybasic, usually dibasic, carboxylic acids, which may be aliphatic and/or aromatic in nature. The polyanhydride may be a homopolymer or a copolymer and has at least 2 monomer units on average per chain. The polyanhydride is preferably made by reacting the free dibasic acids with excess acetic anhydride and refluxing until the desired molecular weight is achieved followed by removal of acetic acid formed and excess acetic anhydride. Examples of polyanhydrides are polymers of sebacic, adipic, azelaic, succinic, fumaric, iso- and per-phtalic and citric acids. The polyanhydrides are solids which are easy to handle, relatively storage stable and give bleach activation.

摘要： Aqueous alkaline isotropic liquid detergent composition comprising a mixture of nonionic and anionic surfactants and hydrgen peroxide. The composition is suitable for use as a laundry detergent and is characterised in that it contains a mixture of two hydrotropes, one of which is an aryl sulphonate hydrotrope. The use of the specific combination of two hydrotropes in these compositions results in reduced pH drift without compromising peroxide stability. This feature of reduced pH drift is unexpected since when used individually in a complete formulation, the hydrotropes promote pH drift towards the acid.
摘要翻译：包含非离子和阴离子表面活性剂和过氧化氢的混合物的碱性各向同性液体洗涤剂组合物。该组合物适合用作衣物洗涤剂，其特征在于它含有两种水溶助长剂的混合物，其中之一是芳基磺酸盐水溶助长剂。在这些组合物中使用两种水溶助长剂的特定组合导致pH漂移降低而不损害过氧化物稳定性。降低pH漂移的这个特征是出人意料的，因为当在完整的配方中单独使用时，水溶助长剂促使酸向pH漂移。

摘要： N-acyl compounds known as bleach activators especially tetraacetylalkylene diamines, are reacted with a peroxygen source in aqueous solution at an acidic pH to form an oxidising product which is a stronger oxidising agent than the peroxygen source used as the starting material. The product solution is used for instance as a bleach or disinfectant. The activator and peroxygen source may be provided as a concentrate product ready for dilution with components able to produce acidic pH in the aqueous solution. The product is, for instance in particulate solid form containing granules of activator and different granules of peroxygen source.

摘要： Non-ionic rich concentrated aqueous alkaline isotropic liquid detergent composition, suitable for use as a laundry detergent and comprising a mixture of non-ionic surfactant and anionic surfactant, together with a hydrotrope and hydrogen peroxide. The composition additionally contains citrate and the total surfactant level is at least 30 %, preferably 35 %. The use of citrate in the composition is found to give reduced downward pH drift compared to the corresponding non-citrate formulations. Peroxide stability in both types of formulation is similar.

摘要： A process for making a coated bleach component which may be incorporated into a detergent composition comprising hydrogen peroxide solution. The process includes the steps of dispersing the bleach component in a continuous liquid phase to form discrete islands of dispersed phase and subsequently forming a polymeric coating at the interface between the dispersed phase and the continuous phase. The coating formed is resistant to hydrogen peroxide solution and is removable when the liquid continuous phase is diluted with aqueous wash liquor. In this way particulate material which reacts with hydrogen peroxide can be incorporated into an aqueous detergent liquid which contains dissolved hydrogen peroxide, whilst maintaining stability.
摘要翻译：一种制备可包含过氧化氢溶液的洗涤剂组合物的涂覆漂白组分的方法。该方法包括将漂白组分分散在连续液相中以形成离散的分散相岛并随后在分散相和连续相之间的界面处形成聚合物涂层的步骤。所形成的涂层耐过氧化氢溶液，并且当用含水洗涤液稀释液体连续相时可以除去。以这种方式，与过氧化氢反应的颗粒材料可以并入含有溶解的过氧化氢的水性洗涤剂液体中，同时保持稳定性。

摘要： Concentrated aqueous alkaline isotropic liquid detergent composition comprising a mixture of nonionic and anionic surfactants and dissolved hydrogen peroxide. The mixture also contains a hydrotrope selected from the group comprising polyhydric alcohols with a flashpoint greater than 30 DEG C, other alcohols with a flashpoint greater than 30 DEG C or mixtures thereof. The composition is suitable for use as a laundry detergent and since it is substantially free from ethanol or other C1-4 monohydric alcohols, stability of the composition is increased and the danger of explosion from a mixture of low flashpoint alcohol and peroxide is reduced.
