Scientific use of washing powder and detergentWhen washing clothes, many people often wonder, which is the best effect of washing powder and soap, will the effect be better when used together, or are there other alternative detergents? There is a rumor on the Internet that washing powder is acidic and soap is alkaline. When used together, acid-base neutralization will occur, and the washing effect will be offset. is this real?
The main component of washing powder is sodium dodecyl benzene sulfonate, soap is a mixture of higher fatty acid metal salts, the carbon number is generally 10 to 18, and the metal is mainly sodium or potassium.
Both have a pH value of 9~10, and both are slightly alkaline. Obviously, acid-base neutralization reaction will not occur when used at the same time. But washing powder contains a kind of foam booster, which functions to foam, stabilize foam, penetrate and remove dirt, and resist hard water. A large amount of foam will be generated during washing. The foam increases the contact range of washing powder and clothes. If washing powder is used together with soap, the soap will inhibit the foaming ability of the washing powder and reduce cleaning efficiency.
At present, various types of detergents such as washing powder, liquid detergent, soap and soap powder appear on the market. How to choose and use it scientifically? Washing powder is a cost-effective synthetic detergent. It has the advantages of strong detergency, good solubility, convenient use, resistance to hard water, and rich foam. At present, an enzyme is added to washing powder, which is an alkaline protease biocatalyst, which can remove stubborn protein stains, such as blood stains, milk stains, and grass stains. The washing effect of washing powder in warm water is better than that of cold water, and the water temperature is preferably 30℃ to 60℃. Soak the washing powder in water above 60℃, the enzyme will lose its activity and affect the decontamination effect. Washing powder is suitable for washing jeans, heavy coats, curtains, etc.
Washing powder is not suitable for washing wool, silk and other clothing. Because clothing such as wool and silk contains protein, alkaline detergents can damage clothing. If it is detergent with enzymes, it will destroy the protein fiber structure of wool and silk clothing and cause damage to the clothing.
Soap is produced from natural oils through saponification reaction. It has strong detergency and good biodegradability. It has no toxic and side effects to the human body and no pollution to the environment. However, in hard water, the replacement reaction between soap and calcium and magnesium ions will form soap scale, reducing its decontamination ability, and the soap scale is easy to adhere to the clothes, making the washed clothes hard.
The composition of liquid laundry detergent is similar to that of washing powder, with low alkalinity and milder performance. It does not damage clothes and is suitable for washing underwear, bed sheets, etc. It has good water solubility and can be quickly dissolved in cold water to give full play to its effect. Low-foaming non-ionic surfactants are often added to laundry detergent, so it is easier to rinse. Generally, non-ionic surfactants resistant to hard water are used for laundry detergents, which are effective in soft and hard water. The neutral silk and wool laundry detergent has low alkalinity and can wash delicate fabrics such as silk and wool.
The decontamination principle of soap powder is the same as soap. Compared with washing powder, soap powder has a better softening effect and effectively reduces clothing damage. It has less foam during washing and is easy to rinse. It still performs well in low temperature and high hardness water. Washing performance. Soap powder is suitable for personal clothing, especially underwear and diapers for infants and young children.
Everyone knows that the traditional way of washing is to use soap horn to wash. With the development of the chemical industry, mankind has already possessed the "artifact" of washing powder. Washing powder and liquid detergent have their own irreplaceable advantages. So which one should I choose when washing clothes? Below we will list the characteristics and advantages and disadvantages of washing powder and liquid detergent, so that everyone is choosing when choosing It will be more convenient.
When washing powder was invented, there was a fact that has been ignored by the public, that is, washing powder contains a lot of alkaline substances. Prolonged use of alkaline substances will not only make the skin surface red, but also The skin causes damage that is difficult to recover in a short time. This is the reason why many housewives who use washing powder to wash laundry all the year round always look red and relatively rough on their hands. Therefore, you must take certain protective measures when using washing powder to wash clothes by hand, such as wearing household plastic gloves to avoid unnecessary damage to the skin.
Compared with the skin-damaging detergent, the neutral detergent with relatively low alkali content will be more friendly to our skin. At the same time, the leavening agent and surfactant contained in the liquid laundry detergent can care for the clothes and fix the color. Another feature of the laundry detergent is that its fragrance lasting is higher than that of the washing powder, which is also more and more people choose The reason why laundry detergent washes clothes.
From the perspective of easy storage, laundry detergent is also better than laundry detergent. The reason is that washing powder is powdery, while liquid detergent is liquid. We all know that powdery objects are prone to damp and agglomerate. This will undoubtedly affect the cleaning ability of washing powder, while washing liquid that is easy to store Don't worry about this kind of problem. But washing powder is not "useless". The cleaning ability of alkaline washing powder is higher than that of neutral detergent, and the price of washing powder is relatively cheaper. This is one of the reasons why many people choose washing powder. However, from the perspective of environmental protection, compared with alkaline washing powder, it is more likely to be degraded and less likely to cause water pollution. For a greener ecological environment, laundry detergent would be a better choice.
