What is the ingredient of soap, the main ingredient of soap

Soap is also known as high-grade fatty acid soap, and the scientific name is carboxylate. Carboxylates are generally made by saponification of oils and alkalis under heating conditions. It is an anionic surfactant. Due to the different oils and fats used and the different alkalis used, laundry soaps can be made with very different properties.

Due to the difference in the freezing point of these soaps, their hardness also varies. The hardness of a high freezing point is large, and the hardness of a low freezing point is small. Sodium soap is harder than potassium soap, while amine soap is softer.

Sodium soap and potassium soap have a rich lather and high detergency in soft water. However, its aqueous solution is highly alkaline, about pH 10. Amine soap, on the other hand, can be used around pH8, which has special advantages.

Soap is a sodium salt of carboxylic acid, R-CO2Na, in which the R group is generally different, is a variety of hydrocarbon groups, R- is a hydrophobic group, and the carboxyl group is a hydrophilic group, in hard water soap and Ca2+, Mg2+, etc. form a curd-like substance, fatty acid calcium salt, etc., that is, commonly said "calcium soap" and become a useless descaler, the softener can be added to hard water to remove hard water ions, so that the soap plays a role.

Decontamination principle: The molecular structure of soap can be divided into two parts. At one end is the charged polar CoO- (hydrophilic site) and at the other end is a non-polar carbon chain (lipophilic part).

Soap can destroy the surface tension of water, when the soap molecules enter the water, the polar hydrophilic part, will destroy the attraction between the water molecules and reduce the surface tension of the water, so that the water molecules are evenly distributed on the surface of the clothes to be washed. The lipophilic part of the soap penetrates deep into the oil stain, and the hydrophilic part dissolves in the water, and this conjugate is stirred to form smaller oil droplets, and its surface is covered with the hydrophilic part of the soap, and will not re-aggregate into a large oil stain. This process (also known as emulsification) is repeated several times, and all the oil stains are dissolved in water as tiny droplets that can be easily rinsed off.

Laundry soap is a type of soap.

Saying that soap environmentally friendly laundry soap is not environmentally friendly, I think first of all, we should distinguish between soap in the broad sense and soap in the narrow sense, the so-called environmental protection here should refer to those handmade soaps without any chemical additives, the products of this oil and alkali, only soap and glycerin two parts, can be completely degraded after use, so it is environmentally friendly. In order to reduce the cost of reducing the premise of making soap, soap can produce rich foam, sufficient hardness, and long shelf life, many chemicals (synthetic colors, synthetic fragrances, preservatives, antioxidants, foaming agents, hardeners, viscous agents, synthetic surfactants) will be added, and these ingredients cannot be degraded by nature, of course, such soaps are not environmentally friendly. Laundry soap is this soap with added chemicals.

Fatty acids, sodium salts and bubble alkali.

Fat and sodium hydroxide are boiled together and hydrolyzed into sodium and glycerol, which are processed and molded into soap.

It is better to use laundry soap when washing underwear, and it is better to have laundry detergent for washing dirty clothes outside.

Ingredients of soap: sodium salt R-Co2Na of carboxylic acid, synthetic coloring, synthetic fragrance, preservative, antioxidant, foaming agent, hardener, viscous agent, synthetic surfactant.

Soap is a general term for metal salts of fatty acids. The general formula is rcoom, where rcoo is the fatty acid group and m is the metal ion. The carbon number of fatty acids in daily soap is generally 1-18, and the metal is mainly alkali metals such as sodium or potassium, and there are also special purpose soaps made of ammonia and some organic alkalis such as ethanolamine and triethanolamine.

Broadly speaking, fatty acid salts obtained by saponification or neutralization reactions with alkalis, such as oils, waxes, rosins or fatty acids, can be called soaps. Soap can be soluble in water and has the effect of washing and decontamination. The various types of soap include soap, also known as toilet soap, metal soap and compound soap.

The main ingredient is sodium stearate, and its molecular formula is C H Coona (carbon 17 hydrogen 35 + carbon + oxygen + oxygen + sodium) (can also be written as RCO Na, which is produced by the reaction of sodium hydroxide [NaOH] and alkaline grease).

Soap is a general term for fatty acid metal salts, the number of fatty acid carbon in daily soap is generally 10-18, the metal is mainly alkali metals such as sodium or potassium, and ammonia and some organic alkalis such as ethanolamine, triethanolamine and so on are also used to make special-purpose soap.

Soaps include laundry soaps, toilet soaps, metal soaps, liquid soaps, as well as related products such as fatty acids, hardened oils, glycerin, etc.

Ingredients of soap: sodium salt of carboxylic acid R-CONA, synthetic coloring, synthetic fragrance, preservative, antioxidant, foaming agent, hardener, viscous agent, synthetic surfactant.

The main component of soap is the sodium salt R-CO2NA of carboxylic acids. Soaps include laundry soap, soap, metal soap, liquid soap, etc. The reason why soap can remove stains is because it contains special molecules that are hydrophilic at one end and lipophilic at the other end, at the interface between water and oil, soap emulsifies the oil and dissolves the oil in soapy water.

The composition of soap is divided into main ingredients and added ingredients.

1. Main ingredients: sodium fatty acid generated after caustic soda saponification reaction after mixing various animal fats and vegetable oils. This is the body of the washing ingredient of the soap.

2. Added ingredients: rosin, sodium silicate, CMC ......These ingredients can increase the hardness of the soap, increase the foaming properties, and increase the decontamination ability of the soap.

3. The view on the fifth floor is a bit of a fuss. It is impossible to add sodium alkylbenzene sulfonate (LAS) to the soap, this LAS cannot be made into a solid form! This is the main body of laundry detergent, and it is not as scary as he said, people in the United States and Germany have used las laundry detergent for more than half a century, see if people have become cirrhosis and liver atrophy?

Is it reliable? Quoted from.

The main ingredient of soap is sodium stearate, and its molecular formula is chcoona (carbon 17 hydrogen 35 + carbon oxygen sodium oxygen) (can also be written as rcona, which is produced by the reaction of sodium hydroxide and alkaline grease).

Soap is a general term for fatty acids and salts, and the number of fatty acid carbon in dust-type soap is generally 10-18, and the metal is mainly alkali metals such as sodium or potassium, and there are also special purpose soaps made of ammonia and some organic alkalis such as ethanolamine and triethanolamine.

Precautions for using soap

1. Pay attention to the production batch number before purchase (some are the production date, some are the limited date), and the shelf life of general laundry soap is three years.

2. How to use, generally unpack the package, soak the clothes to be washed with water and directly rub the jujube on it, scrub it by hand, and repeat the washing of the key hard-to-wash parts several times.

3. Be careful not to get into your eyes during use, if you accidentally get into your eyes, you can immediately rinse with plenty of water.

4. After use, remove the water in the soap tray to prevent the soap body from rotting.
