Anonymous users2024-02-07Soap, rinsing saves time and effort, but soap is not very practical, most of them are used in hand washing, and there is still a fishy smell of soap on the clothes, which is very bad Laundry detergent, convenient and easy to use, the residual fragrance on the clothes is the fragrance, but this is water-efficient, it must be rinsed many times before there is no foam, if you do not rinse the residual laundry detergent will hurt the body** health There is also a kind of soap powder that is very good now, that is, soap powder, which is more suitable for children's laundry cleaning.

Anonymous users2024-02-06There are many people who think that laundry detergent and soap cannot be used together, but this is actually a misconception. First of all, soap (the main ingredients of fatty acid sodium salt and bubble alkali) and laundry detergent (the main ingredients of sodium alkylbenzene sulfonate and sodium tripolyphosphate) are all alkaline chemical products, and their pH is between 9 11, and there is no so-called "acid-base neutralization"; Secondly, sodium fatty acids, the main ingredient of soap, will combine with calcium and magnesium ions in water and precipitate, affecting the detergency. The sodium tripolyphosphate contained in the laundry detergent has the effect of complexing calcium and magnesium ions and softening hard water, which can improve the decontamination ability of soap rather than reduce it; Third, sodium fatty acids in soap and sodium alkylbenzene sulfonate in laundry detergent can produce a "synergistic decontamination effect", improving the decontamination ability of both.
Fourth, soap can inhibit the foaming ability of laundry detergent, making it easy to rinse and overclean. Due to the many benefits of mixing the two, the high-efficiency low-foaming laundry detergents on the market today already contain 3 to 5% soap.

Anonymous users2024-02-04Treat it on a case-by-case basis, some situations are okay, some situations are not.
The difference between soap powder and laundry detergent is that the main ingredient of soap powder is sodium fatty acids, while the main ingredient of laundry detergent is sodium alkylbenzenyl transverse acid. In addition, there are a variety of washing aids in laundry detergent, such as water softeners, alkaline agents, and so on. Therefore, relatively speaking, laundry detergent is more suitable for ordinary water containing hardness ingredients, and when soap and soap powder encounter hard water, an insoluble precipitate called fatty acid calcium will be generated, which is the soap stain we see.
These soap stains are deposited on clothing, especially dark clothing, and some white marks will be seen. For protein fibers such as wool and silk, they are easy to absorb these soap dirt, which not only affects the color, but also affects the feel and makes the clothes harder.
Therefore, soap powder is best used in the washing of light-colored clothes made of cotton and chemical fiber. For dark clothes, it's best not to use them. Or mix it with laundry detergent to complement each other's strengths.

Anonymous users2024-02-03In terms of chemical properties, soap and laundry detergent are both alkaline chemical products, and their pH values are 8 11, so there is no such thing as "acid-base neutralization" when washing powder and soap are mixed.
Other studies have shown that a mix of laundry detergent and soap in the right proportion is more effective in removing stains. This is because sodium fatty acids, the main component of soap, will combine with calcium and magnesium ions in the water to form a precipitate, which affects the detergency of soap. When laundry detergent and soap are used together, the sodium tripolyphosphate contained in the laundry detergent has the effect of complexing calcium and magnesium ions and softening hard water, which can improve the decontamination ability of soap.
The sodium fatty acid in soap and sodium alkylbenzene sulfonate in laundry detergent can also have a "synergistic decontamination effect", which can improve the detergency of both. In addition, soap inhibits the foaming ability of laundry detergent, making it easy to rinse dirt on clothes.

Soap and laundry detergent are alkaline. The main components of soap are fatty acids, sodium salts, and bubble flowers. The pH is around 8.
The main ingredients of laundry detergent are sodium alkylbenzene sulfonate and sodium tripolyphosphate, and the pH value is around 10. We all know that if the pH is greater than 7, then it is alkaline. Therefore, soap and laundry detergent are both alkaline products, and the two can be mixed.
Laundry detergent has the ability to foam, which makes it difficult to rinse clothes. Soap inhibits the foaming ability of laundry detergent, making it easy to wash clothes. In fact, the most high-efficiency low-foaming laundry detergent on the market originally contains 3 5% soap ingredients.
Do not mix laundry detergent with disinfectant.
Classification of laundry detergent: 1. Ordinary laundry detergent and concentrated laundry detergent: ordinary laundry detergent has large and loose particles, good solubility, rich foam, but relatively weak detergency, not easy to rinse, and is generally suitable for hand washing; Concentrated laundry detergent, small particles, high density, less foam, but strong detergency (at least twice that of ordinary laundry detergent), generally suitable for machine washing. >>>More

Which is better, "laundry detergent" or "laundry detergent"?
In this case, it is the main reason why it cannot be added to laundry detergent, because it will have a series of display reactions after adding laundry detergent, in which case, it cannot be applied.
