Description

¥ Particle Detergent Compositions Full Description BACKGROUND: The present invention relates to particulate detergent formulations; It combines well-formed cleaning performance; Between high bulk density and excellent powder© properties. The formulations contain a high level of high performance surfactant and optionally selected ethoxylated alcohol plus a small amount of alkyl sulfate, zeolite and a zeolite detergency builder; It is preferable to prepare it by agglomeration process using a granulator (forming granules) / high-speed mixer. Ve and Hadiths; The trend towards detergent powders is towards increasing their volumetric (overall) density; For example above 100 g/l and those powders of higher density or 'concentrate' are prepared by different methods; Some call for thickening that spray-dried powder; and others based on the basis of dry mixing (Joly dry mixing or alle other completely non-turret processes) 100-107 Vo The movement towards higher densities, which is accompanied by less porous particles, makes the incorporation of high levels of Mobile organic components without losing the properties of the powder glide more difficult Whatever it is, it becomes desirable to improve the performance of the cleaning ability by incorporating high levels of surfactants, and by using surfactants that have the highest possible effectiveness against Loily and fatty soils One class of materials Surfactants consist of ethoxylated alcohols with a relatively low degree of ethoxylation ¢ and these are generally mobile liquids at ambient temperatute In view of increasing the caveats dnd it has also become desirable to use alkyl sulfates, preferable to sulfonates Linear alkyl benzene traditionally used in laundry detergents.JS sulfate is biodegradable and can be obtained from renewable sources of

Renewable such as coconut oil and palm oil. Jey er Ja is generally more difficult to manufacture into high quality detergent powders than alkyl benzene sulfonates. It was found that the surfactants are non-ionic; alkyl sulfate and a mixture of the two; Provides effective cleaning ability. High; Sly because of its mobility; Ja © is difficult to combine at intermediate levels; in free-flowing powders; ly will disperse Codi in the washing up liquid; And when a higher percentage of surfactants is required; For cleaning performance to ever higher levels; It is expected that these difficulties will increase; The higher concentrations are steadily increasing and at present the bulk powders are preferred by the consumer and the detergent industry. Whatever it is, the current inventors have succeeded in formulating detergent powders with high NV volumetric density, free-flowing, and Gliese cleaning performance with powder properties and good dispersibility; Although it contains relatively high levels of mobile surfactants with high performance. The powders of this invention contain relatively high levels of zeolite, a zeolite builder; It may be prepared by the granulation process in the Je speed granulator/mixer. Good powder properties can be obtained; Especially using the new Zeolite Vo Zeolite Pozeolite; As a dl material, a special aa cleaning ability can be obtained by using selected non-ionic surfactants.

Of industrial alcohols, ziegler alcohols are preferred over oxygen-based alcohols, ox0-based alcohols.

According to a preferred embodiment (SU) (ep) which gives exceptionally good cleaning power to an oily soil, ethoxylated Jas (which of course is always a mixture of species with different numbers of EO units) is a material of narrow range. range in which the distribution of the ethoxylated os species has a higher peak around one dominant value than in the case of using conventional commercial non-ionic m surfactants. The content of unethoxylated is also generally lower; Its content may be reduced further by what is called stripping or stripping.
