The ancients used plant ash as washing powder.

In ancient times, plant ash was a common cleaning agent. It is made simply by burning the plants and collecting the burning residue. This residue is plant ash. Due to its strong alkaline nature, plant ash effectively removes stains and grease from clothing.

Not only that, plant ash has many other uses. It can be used to make soap and shampoo and can be used to clean homes and utensils. In addition, plant ash can also be used as fertilizer to provide nutrients to farmland.

However, despite the many uses of plant ash, its use is not without limitations. Plant ash is highly alkaline, so when using plant ash, you need to use it in an appropriate amount and pay attention to protection.

Industrial laundry detergent production method

Mix 25% soda ash, 1% methylcellulose, 10% Yuanming powder, 6% dodecyl benzene sulfonic acid, and alkyl phenol Ether (TX-10) 4%, lauric acid diethanolamide (6501) 1% are mixed in proportion and stirred evenly. Then add 53% of the puffed powder to the previous mixture, mix again and stir evenly, and then sift through a 20-mesh sieve. After sifting, it can be bagged.

If the washing powder requires a white color, dodecyl benzene sulfonic acid can be changed to alkyl phenol ether TX-10, or 0.1% fluorescent powder can be used as a whitening agent. If you want to add fragrance to the laundry detergent, add an appropriate amount of fragrance to the first step mixture. If you want to add enzymes, you can add alkaline egg enzyme directly to the washing powder and mix well. The dosage is 2% to 3%, and the amount of enzyme added in the formula can be reduced.

In addition to the above raw materials, skin protectants, rust inhibitors, fabric softeners, antioxidants, emulsion stabilizers, etc. can also be added to the washing powder according to different uses. Civilian laundry detergents produced in my country generally use sodium alkylbenzene sulfonate as the main active ingredient, coupled with other builders, while foreign laundry detergents use sodium tripolyphosphate in greater amounts.
