Definitions
- a particulate detergent composition comprising phosphate containing detergent base and a solid blend of peroxy compounds comprising inorganic peroxidic compounds selected from the group consisting of percarbonates, perborates in the form of an active oxygen containing material consisting of substantially regular particles of which at least 80% by weight have diameters which vary by not substantially more than 25% from the average mean diameter of the inorganic peroxy compound particles.
- the perborate and percarbonate components manifest the bulk density of 1:3 times that of the detergent base and an average mean particle diameter within 25 of the norm.
- the invention relates to peroxy compounds and particularly to detergent compositions containing peroxy compounds.
- This invention provides a particulate detergent composition
- a particulate detergent composition comprising a major proportion, based on the weight of the detergent composition, of a homogeneous detergent base having a normal size distribution and consisting of substantially regular particles and, distributed therein, a minor proportion, based on the weight of the detergent composition, of an active oxygen containing compound or compounds in the form of an active oxygen containing material consisting of substantially regular particles of which at least 80% by weight have diameters which vary by not substantially more than 25% from the average particle diameter of the material, having a bulk density of from 100% to 300% of that of the detergent base and having an average particle diameter of where X has a value of from 0.4 to 0.7 and when P, B and B are as herein defined.
- P, B and B used herein denote numerical values equal, respectively, to the average particle size of the detergent base in mm. and the bulk density, measured as herein described in g./cc., of the active oxygencontaining material and of the detergent base.
- a normal size distribution we mean a distribution which varies in a continuous manner and peaks at a point intermediate to the minimum and maximum particle size.
- compositions according to the invention must consist of substantially regular shape, we prefer them to be generally spherical.
- diameter of particles herein we mean the diameter as determined by conventional sieve analysis using a nest of sieves.
- Solid detergent compositions which comprise a blend of a minor proportion of a particulate active oxygen-containing compound and a major proportion of a homogeneous particulate material which contains the remaining constituents of the detergent composition (the detergent base) may tend to segregate. It is, however, desirable that the active oxygen containing compound remain distributed throughout the detergent composition. It has been proposed in the past to reduce the tendency of blends to segregate by ensuring that their various constituents have a similar size distribution.
- Active oxygen containing compounds often have a lower rate of solution than the detergent bases conventionally used and particles of a size which corresponds to the largest found in the detergent base may remain undissolved after the remainder of the composition has gone into solution. It may therefore be disadvantageous to attempt to reduce the tendency of such compositions to segregate by matching the particle size distribution of their constituents.
- the detergent compositions provided by the present invention have excellent characteristics in relation to their tendency to segregate, particularly in comparison with similar blends in which the minor proportion has an average particle diameter outside the essential limits set forth above, and also have acceptable rates of solution.
- phosphate containing detergent base having a normal particle size distribution
- a preferred species of phosphated detergent base is that material known by the trade name Deepio marketed by Procter & Gamble, Cincinnati, Ohio, which is a mixture of 34% by weight sodium tripolyphosphate, 7% by Weight sodium silicate, 29% by weight sodium sulphate and minor ingredients, 23% by weight sodium dodecyl benzene sulfonate, the balance of the composition being Water.
- detergent base which may either be cationic, anionic or non-ionic
- phosphate builders may be added to detergents such as alkyl sulphates and alkane sulphonates to increase their detergent effciency as well as their anti-corrosive properties.
- Sodium hydrogen phosphate is claimed to be an efiective builder for a variety of sulfonic and sulfuric ester detergents as described in US. Pat. 2,383,502 to Quimby.
- mixtures of tetrasodium-p-phosphate and acid reacting salts which provide a pH of less than 7, have been used for the same purpose particularly with respect to detergents of the type described in Henderson et al. US. Pat. 2,279,314.
- Other detergent bases, therefore, which contain phosphate ions are particularly useful in the practice of this invention.
- the minor proportion of the detergent composition comprises, substantially solely, one or more active-oxygen containing compounds.
- the preferred active oxygen containing compounds are inorganic peroxidic compounds for example alkali metal peroxidic compounds such as percarbonates, perborates, persulphates, perphosphates and perpyrophosphates.

- the detergent base has an average particle size of from 0.3 to 0.7 and/or a bulk density of from 0.2 to 0.5 g./ cc.
- the active oxygen-containing material is advantageously present in not more than 25%, preferably not more than 20%, by weight of the detergent composition and it advantageously also has a bulk density of from 100% to 270% of that of the detergent base.

- X has a value of from 0.4 to 0.7
- P, B and E are as herein defined.
- Detergent compositions provided in this last embodiment of the invention show, particularly, a reduced tendency to segregate.
- the detergent base has a bulk density of 0.2 to 0.5 g./ cc. and/ or has an average particle size of from 0.3 to 0.7 mm. in diameter.
- the alkali metal perborate or percarbonate has an average particle diameter expressed in mm. by the general formula referred to above wherein X is a numerical value of from 0.45 to 0.65.
