Facing a lot of leftover scraps from soap cutting and failed sponge cakes, I made an environmentally friendly washing powder that is simple and easy to learn, low carbon and no waste. I hope it can bring some benefits to the soap making life of soap lovers. Another new idea, please correct me if there are any mistakes.
This method is suitable for making soap crumbs with few impurities and a single color. If the soap crumbs contain too many additives such as powder, mud, flowers, and pigments, it will easily cause secondary pollution to the washed clothes. Develop the habit of sorting and sorting soap scraps when collecting them. When making washing powder from soap scraps that contain more additives, the salting out method should be used to separate out the impurities before making it.
In order to have more and stronger washing functions, commercially available laundry detergents often add surfactants, builders, stabilizers, whitening agents, flavors and enzymes, etc., to achieve easy solubility, cleanliness, softening, and Foaming, preventing static electricity on clothes, etc.
Homemade washing powder first solves the problem of disposal of scraps and waste soap. Secondly, the additive is only edible soda ash (baking soda). Its main component is sodium carbonate. In addition to being used for making steamed buns, it can also be used for cleaning. It removes dirt and residual pesticides from vegetables. In the old days when soap was in short supply, people often used it to wash clothes.
Picture below: Collect soap scraps and chop them into small pieces to facilitate dissolution.
The picture below: Prepare 1200 grams of soap crumbs and 600 grams of edible soda ash (about half the weight of the soap crumbs).
Picture below: Pour crushed soap into a stainless steel basin.
The picture below: Add about 2400 grams of water (twice the weight of soap crumbs). I want to make a special note here. It doesn’t matter if you add more or less water.
The purpose of adding water is to melt the soap crumbs. Adding more water will make it easier to melt, but the drying time may be longer in the future, and vice versa.
Picture below: Over low heat, slowly stir and melt the soap crumbs (adding water and letting it sit overnight will speed up the melting).
The picture below: Pour in 600 grams of edible soda ash (about half the weight of the soap crumbs)
Picture below: Stir evenly
Picture below: Dry in a net bag or flat for one to two months (depending on weather conditions) until dry.
The picture below: Grind the dried soap bar into powder or crush it (the more crushed it is, the easier it will be to dissolve in water)
Picture below: Grinding into powder is a troublesome process. If there are no grinding tools, dry soap bars can be crushed and used.
