Detergent formula

Formulation processes for household soap, laundry detergent, and dishwashing liquid 1. Principle of soap making: Fats + NaOH = RCOONa + CH2OHCHOHCH2OH. The value of R depends on the type of natural fat used; different raw materials result in soaps with varying properties, the most noticeable difference being in their operating temperature range. When using soap, it should be noted that in acidic environments soap forms insoluble fatty acids, and in hard water it forms calcium and magnesium salts, which leads to its loss of effectiveness ； Soap is also prone to having its properties altered by electrolytes. Production process: Fats and alkali solutions are placed in a saponification tank and heated to boiling; after saponification, the mixture is transferred to a salting-out tank where concentrated brine is added for salting-out. The soap formed on the surface is then refined to produce the final product ； Lower-layer glycerol is recovered and processed as a by-product. 　2. Laundry detergent formula: file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image002.jpg Production process: First, soda ash, carboxymethyl cellulose, and sodium triphosphate are mixed evenly in a mixer. Then, dodecylbenzene sulfonic acid, sodium hypochlorite solution, and sodium silicate solution are added, and mixing is continued until uniformity is achieved. Then it is poured onto the concrete floor and piled to a height of 10–15 cm; it is left there for 24 hours before being fed into a grinder for grinding, and then transferred to a mixer. 1/9 part of sodium perborate and 1/90 part of fluorescent brightener were added. 3. Detergent Formula: file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image004.jpg Production process: Place dodecylbenzene sulfonic acid, sodium sulfate, and water in a mixer; after mixing, add a 10% sodium hypochlorite solution and stir for about 20 minutes until complete bleaching occurs. One ethanolamine laurate and one ethanolamine were placed in another container; after heating to dissolve them, they were added to the mixer and stirred until a colorless and transparent solution was obtained.
