Definitions
- This invention relates'to the manufacture of soap powders of the kind known as perborate soap powders.
- Such powders contain perborate (usually sodium perborate), soap and sodium silicataand as a rule sodium carbonate, minor proportions of other suitable ingredients being sometimes present.
- Methods of producing the powders are well known.
- the characteristic bleaching properties (as distinct from the purely detergent properties) of the powders are dependent upon their content of active or available oxygen. As hitherto manufactured they possess the disadvantage that under certain conditions of storage, particularly when packed in cartons as is usual, they suifer a progressive, more or less gradual, decomposition of the perborate with corresponding loss of active oxygen.
- The'invention is based on the discovery that .the loss of oxygen from a perborate soap powder containing sodium silicate is greatly decreased by the addition of a small percentage of a suitable salt of magnesium.
- perborate soap powders containing sodium silicate and magnesium salt losp oxygen far less readily than perborate soap powders containing magnesium salt but no sodium silicate, sodium silicate but no magnesium salt or perborate soap powders alone.
- magnesium sulphate 1% crystalline magnesium sulphate
- sodium silicate 4 3 Powder containing sodium silicate but no magnesium sulphate Powder containing neither sodium silicate nor magnesium sulphate 4 3
- Suitable salts of magnesium are the sulphate, chloride, and nitrate. Less soluble salts may also be employed, although to less advantage, provided that their fineness of subdivision'and thoroughness of incorporation allow their distribution throughout the product to be sufficiently intimate and uniform.
- magnesium salt to be employed varies to some extent with the nature and proportions of the other ingredients of the powder, but as a rule a quantity thereof equivalent to from about 0.1 per cent. to about 0.3 per cent. of magnesium oxide (MgO) has been found to be suitable.
- ingredients should be thorough and may be elfected in various ways. In order to minimize any loss of active oxygen during the process, it is best to avoid temperatures exceeding 50 C. when the perborate has been added.
- themagnesium compound employed is facilitated by adding it dissolved or suspended in a small quantity of water. It has been found advantageous first to mix the solution or suspension with the soap while the latter is in a pasty or molten condition and thereafter to incorporate the other ingredients, the perborate being preferably added last in order to the risk of loss of active oxygen.
- Example 1 lb. of soap (containing 63% fatty acids] in a pasty or molten condition are added, with thorough mixing, 1 lb. of crystallized magnesium sulphate dissolved in a small quantity of water, 10 lb. of sodium silicate Twad., and 22 lb. of anhydrous sodium carbonate, and to the resulting mixture, when at a temperature not exceeding 50 C., are added 9 /2 lb. of sodium-perborate, the whole being reduced to powder in the known manner.
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises incorporating with the other ingredients of the said soap powder a small proportion of a salt of magnesium.
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises incorporating with the other ingredients of the said soap powder a pro-' portion of magnesium salt substantially equivalent to 0.1 to 0.3 per cent of magnesium oxide (MgOJ 3.
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises incorporating with the other ingredients of said soap powder 0.6 to 1.8 per cent of crystallized magnesium sulphate (MgSOa'lHzO) 4.
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises dissolving a soluble magnesium salt in a small amount of water incorporating this solution with the soap when the latter is in the molten or semi-solid condition and thereafter adding the other constituents.
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises suspending a sparingly soluble salt of magnesium in a small amount of water, incorporating this suspension with the soap when the latter is in the molten or semisolid condition and thereafter adding the other constituents.
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises dissolving in a small amount of water an amount of magnesium salt equivalent to 0.1 to 0.3 per cent of magnesium oxide (MgO) on the weight of the soap powder,
- a process for the manufacture of a perborate soap powder containing sodium silicate which process comprises suspending in a small amount of water an amount of a sparingly soluble magnesium salt equivalent to 0.1 to 0.3 per cent of magnesium oxide (MgO) by weight on the soap powder, incorporating this solution with the soap when the latter is in the molten or semisolid condition and thereafter adding the other constituents.
- MgO magnesium oxide
- a perborate soap powder containing sodium silicate and as stabilizing substance a soluble or sparingly soluble magnesium salt in amount equivalent to 0.1 per cent to 0.3 per cent of magnesium oxide (MgO) on the weight of the soap powder intimately incorporated therewith.
- MgO magnesium oxide
