Detergent types and scope of application are involved in intermediate pharmaceutical preparations. In order to better understand, the relevant knowledge of detergent types and scope of application is organized as follows, I hope to help!

Professional detergents:

Professional detergents are classified separately, mainly in hotels, hospitals, and hotel detergents, and are used in large laundry industries such as laundry rooms. Including cleaning agents for public facilities, textile industry cleaners, leather cleaners, food industry cleaners, vehicle cleaners, metal cleaners, optical glass cleaners, plastic rubber cleaners and other industrial cleaners.

Common surfactants for industrial cleaning agents: cationic surfactants / anionic surfactants / amphoteric surfactants / nonionic surfactants, and general low foaming detergents are commonly used for nonionic surfactants.

Household detergents:

There are two main types of washing supplies: one is fat (scented) soap; the other is synthetic detergent. Among synthetic detergents, laundry powder accounts for about 2/3, liquid detergent accounts for about 1/3, and solid synthetic detergents are relatively small.

In the field of textile washing, soaps, granules or powdered laundry detergents, liquid jujube-like liquid detergents are the most common.

Soap is a sodium or potassium salt of various fatty acids, and is generally produced by saponification of fats and alkalis by a full boiling method, a cooling method, a carbonate method, and the like. There are some restrictions on soap use:

The first is that when it encounters hard water, the washing effect is poor, and obvious dirt may remain. When washing textiles with hard water, the soap and calcium ions and magnesium ions in the water will generate calcium soap and magnesium soap, which will not only waste the soap, but also make the textile color yellow and the fabric sinter.

The second is poor generality. Soap making requires the use of a large amount of caustic soda, which makes the soap alkaline and corrosive, and is not suitable for washing silk, wool fabrics, and some chemical fiber fabrics.

Third, it may irritate the skin. The sodium hydroxide content of soap is usually high, which makes the soap body alkaline and corrosive. On the contrary, human skin is generally in a weak acid environment. When hand-washing, soap irritates and damages the skin greatly. Soothing clothes washed by soap also irritate the skin, causing people to feel sticky and feverish.
