Definitions

• the present invention relates to liquid, pourable, thickened chlorine bleaching compositions, based on an aqueous alkali metal hypochlorite solution which has been thickened by the inclusion therein of a thickening system which comprises at least two different detergent-active agents.
• compositions have been described in the art, e.g. in our British Patent Specification 1 329 086 and our European Patent Specification 0 030 401.
• a specific example of such a mixture of two different detergent-­active agents is the mixture of a trialkylamine oxide having one C8-C18 alkyl group and two C1-C14 alkyl groups and a fully saturated C8-C18 fatty acid soap as described in our British Patent Specification 1 329 086, and the present invention will be in particular concerned with such a mixture, it being understood, however, that the present invention is not restricted to these particular systems, other systems as described in our European Patent Specification 0 030 401 being equally suitable.
• Formulations prepared with a system according to British Patent Specification 1 329 086 are generally quite satisfactory, and have a viscosity up to about 150 cS at 25°C. Higher viscosities can also be obtained with these mixtures by varying the ratio between the trialkylamine oxide and the saturated fatty acid soap and using certain levels of both ingredients. Thus, products with a viscosity of 300 cS at 25°C can be obtained to provide increased-viscosity products.
• the object of the present invention is to provide a liquid, pourable, thickened chlorine bleaching composition having an increased viscosity at 25°C, and having an appropriate viscosity at lower temperatures and at low shear. More in particular, the object of the present invention is to provide such products having a low shear (plateau) viscosity) of up to 1500 cP, preferably up to 1000 cP and most preferably between 300 and 1000 cP at a shear of less than 20 sec. ⁇ 1 at a temperature of below 25°C, especially at 10°C or below, and having a viscosity of 150-700, preferably 200-400 cP at a temperature of 25°C.
• a low shear (plateau) viscosity) of up to 1500 cP, preferably up to 1000 cP and most preferably between 300 and 1000 cP at a shear of less than 20 sec. ⁇ 1 at a temperature of below 25°C, especially at 10°C or below, and having a viscosity of 150-
• the products should be formulated to have a cloud point of at least 55°C, preferably at least 60°C, using a weight ratio of trialkylamine oxide to saturated fatty acid soap of 75:25 to 50:50, and using a total level of trialkylamine oxide plus saturated fatty acid soap of 1.25 to 3, preferably 1.5 to 2% by weight of the total composition.
• compositions of the invention furthermore contain from 1-15% preferably 5-10% by weight of active chlorine, e.g. of alkali metal hypochlorite, and may contain the usual additives such as colouring agents, perfumes, buffers, free alkali etc. as e.g. described in our aforementioned patent specifications.
• active chlorine e.g. of alkali metal hypochlorite
• a material can be used which generates a fatty acid in the composition, e.g. a lower alkyl ester of a fatty acid such as isopropyl laurate.
• Thickened liquid chlorine bleaching compositions were prepared having the following formulations:
