Soap powder and laundry detergent are acidic and alkaline

Soap powder, alkaline laundry detergent, acidic.

Laundry detergent is alkaline. The ingredients of laundry detergent are surfactants, soda ash, sodium tripolyphosphate, sodium silicate, carboxymethyl cellulose, and brighteners, among which soda ash, sodium silicate, and sodium tripolyphosphate are all alkaline, so laundry detergent is alkaline. Generally speaking, the pH value of a 1% aqueous solution of laundry detergent is about 10.

Generally speaking, detergents are alkaline, but heavy dirt detergents are more alkaline. In addition, it depends on the nature of the active substances and additives to decide, the general active ingredient of laundry detergent is sodium dodecylbenzene sulfonate, additives are sodium carbonate, sodium tripolyphosphate, etc., so the alkalinity is also strong.

However, laundry detergents are also neutral and acidic, and the recipes used are different depending on the brand, but most of them should be alkaline.

Note: 1. Although alkalinity is conducive to the washing of clothes, excessive alkaline substances will bring harm to clothes and laundry, so the state has made corresponding provisions on the alkalinity of laundry detergent, and qualified laundry detergent should meet these requirements.

2. In addition, as mentioned earlier, these alkaline substances will form a precipitate with hard water, and too much alkaline substances will cause a large amount of precipitation to form during washing, which will make the washing effect worse.

Summary. The main ingredient of laundry detergent is sodium dodecylbenzene sulfonate, soap is a mixture of metal salts of higher fatty acids, the number of carbon atoms is generally 10 18, and the metal is mainly sodium or potassium.

Both have a pH of 9 10 and are alkaline, and the use of them at the same time obviously does not cause acid-base neutralization and reverse stage slamming. However, the washing powder contains a foaming agent, which is foaming, foaming, penetrating and destaining, and resisting hard water, which will produce a large amount of foam in the cleaning, and the foam increases the contact range between the laundry detergent and the clothes. If laundry detergent is used with soap, the soap will inhibit the detergent's foaming ability and reduce the washing efficiency.

Laundry detergent is not suitable for washing clothes such as polyester wool and silk. Because the clothes such as wool and silk contain egg chains, alkaline laundry detergent will damage the clothes. If enzyme laundry detergent is added, it will destroy the protein fiber structure of wool and silk clothes, causing damage to clothes.
