Soap powders

Soaps of other metals such as aluminium, calcium, cobalt, lithium, lead or zinc - see metallic soaps. European production 1976 toilet soap 307 000 tonnes, household soaps c. 140000 tonnes, soap powders c. 35000 tonnes. 

As improvements over P-methylumbeUiferone (55—57), 4-methyl-7-amino-coumarin [26093-31-2] (12a) and 7-dimethylamino-4-methylcoumarin [87-014] (12b) (58—61) were proposed. These compounds are used for brightening wool and nylon either in soap powders or detergents, or as salts under acid dyeing conditions. They are obtained by the Pechmaim synthesis from appropriately substituted phenols and P-ketocarboxyflc acid esters or nitriles in the presence of Lewis acid catalysts (see Coumarin). 

Soaps Soaps in a finely divided form may be classified as soap powder, powdered soap, and chips or flakes. The term soap powder is applied to a granular product. No. 12 to No. 16 sieve size with a certain amount of fines, which is produced in hammer mills with perforated or slotted screens.

Oil spillages onto warm, absorbent materials, such as insulation, also have a limited life (see Sections 7.3.2 and 12.4.4). The oil soon decomposes to materials with a low auto-ignition temperature and self-ignites. As many insulation fires have started in this way, oil-soaked insulation should be removed without delay. Linseed oil ignites particularly easily. This has been known since at least 1925 nevertheless, in 1965 some cloths used to apply linseed oil to laboratory benches were not burned as directed but dropped into a waste bin. A fire started after a few hours and destroyed the laboratory [17J. Reference 18 lists substances that are liable to self-heat, and Reference 19 includes references to a number of incidents that have occuiTed involving substances as diverse as wood shavings, tobacco, milk powder, and soap powder.

General factors affecting spontaneous ignition of soap powders were discussed. 

Soap chips are made by running a thin sheet of melted soap onto a cool cylinder and scraping off the soaps in small broken pieces. Soap granules are dried miniature soap bubbles. Soap powders and scouring soaps contain some soap, a scouring agent (abrasive) such as powdered pumice or finely divided sand, and builders like sodium carbonate and trlsodlum phosphate. Builders make the soaps act more rapidly. The cleansing action of soap has been discussed in Unit 5. 

If any NG id spilled, it should be cleaned up immediately. To do this, mop up first with a wet cloth which should then be put into the sawdust then wash with one of the NG removers ("killers or "destroyers ) and finally wash the area with warm water and soap powder...

To prepare, clean and dry a square, half-gallon milk carton. Pour in 4 cups of fuel and 2 tablespoons of denatured alcohol. Mix well. Add 2 1/2 cups of soap powder or 3 1/2 cups of soap flakes. Stir until it begins to thicken, approximately 15 minutes. Seal the carton with tape and let it sit for 2 days. The mixture will thicken into a firm buttery paste. Chill for an hour in the refrigerator, remove, and carefully peel off the milk carton. Cut the resulting block into 1-inch slabs and place them in individual sandwich bags. Double wrap to help contain the fumes. 

Mixtures with soap powder, soda ash, water-glass or sodium phosphate are also marketed. The advantage of these powders is the lower soap consumption and fabrics washed in them wear longer than when soda ash is used. In medical science perborate is used for oxygen baths and certain antiseptics.
