What is Polyquaternium-4?
"Polyquaternary Ammonium Salt-4" is a compound that is widely used in various fields such as daily chemistry and medicine in this world. Its properties are cationic, and its structure is formed by linking a quaternary ammonium salt group with a polymer skeleton.
In daily chemistry, it is often used as a hair conditioner. Because of its cationic properties, it can interact with the anions on the surface of the hair, making the hair supple, easy to comb, and can reduce static electricity, making the hair more shiny. Looking at the past, although there is no such thing, the ancients also had many wonderful methods for hair care, such as shampooing the hair with plant ash water, which can remove oil; applying egg white to the hair can make the hair supple. Today's polyquaternary ammonium salt-4, the effect is better and more convenient.
In the field of medicine, it can be used as a fungicide and disinfectant. Because it can destroy the cell membranes of microorganisms and cause their inactivation, it can achieve the purpose of antibacterial disinfection. In ancient disinfection, moxa, wine rub and other methods were mostly used. Compared with polyquaternary ammonium salt-4, it has strong bactericidal power and fast action.
In terms of fabric treatment, polyquaternary ammonium salt-4 can be used as an antistatic agent to make fabrics more comfortable to wear. Ancient fabrics, although without this agent, are woven with natural fibers, and the problem of static electricity is slightly lighter. There are many chemical fiber fabrics today, so the use of this agent is very important.
Furthermore, in the paper industry, it can be used as a retention and filtration aid to improve paper quality and production efficiency. Although the ancient man-made paper had a complicated process, there was no such high-efficiency additive. The use of polyquaternary ammonium salt-4 made the paper industry progress. In short, polyquaternary ammonium salt-4 has important functions in many fields in this world. Although it is very different from the ancient method, it is also used to meet people's living and production needs.

What are the main uses of Polyquaternium-4?
Polyquaternium-4 is a commonly used chemical raw material. It has a wide range of uses and is used in daily chemicals, medicine and many other fields.
In daily chemicals, it is often used in hair products such as shampoo and conditioner. Because of its excellent conditioning properties, it can be adsorbed on the surface of the hair to form a protective film, making the hair soft and shiny, reducing static electricity, and can effectively improve the combing properties of the hair, making it easy to take care of the hair. For example, in shampoo formulations, Polyquaternium-4 can adhere to the stratum corneum of the hair, fill damaged areas, repair hair scales, and bring hair back to life.
In the field of skin care products, Polyquaternium-4 also has strengths. It can enhance the moisturizing performance of the product. By combining with water molecules, a moisturizing network is built on the surface of the skin to help the skin retain moisture and keep the skin moist and smooth. And this ingredient is mild, suitable for most skin types, and rarely causes discomfort such as allergies.
In the pharmaceutical industry, Polyquaternium-4 is also useful. Because of its antibacterial properties, it can be used in some external preparations to help inhibit the growth of bacteria, maintain the stability of the drug, and improve the rheological properties of the drug, which is convenient for drug application and absorption. For example, in some ointment formulations, the consistency of the ointment can be adjusted to make it easier to apply evenly to the affected area and enhance the efficacy of the drug.

What is the role of Polyquaternium-4 in cosmetics?
Polyquaternium - 4 is especially important in cosmetics. Its mild nature has many wonderful uses.
First, it can be used as a conditioning agent. It can form a protective film on the surface of the hair, making the hair soft and shiny, without being torn. When combing, it is very smooth, just like ancient silk, with soft tentacles and shiny. On the skin, it can also soothe and soothe, making the skin feel smooth to the touch, like a spring breeze, very comfortable.
Second, it has the effect of thickening. In the formula of various cosmetics, the texture can be adjusted. If the formula is slightly thinner, adding this substance can make it moderately thick, like agar pulp and jade liquid, thick but not sticky, easy to use, and can be spread evenly when applying, just like a painter, the ink is thick and thin properly, and it can be painted.
Third, it has antistatic power. Hair is prone to static electricity due to friction, causing it to be unkempt like grass. Polyquaternium-4 can effectively dissipate static electricity and make the hair subdued and supple, like a thousand troops, with a good general in command, orderly.
Fourth, it has the power of moisturizing. It can absorb and retain moisture on the surface of the skin or hair, keeping the skin hydrated at all times, just like the dew on the petals in the morning, crystal clear and moist. Hair is also not easy to dry and split ends, always maintaining a healthy state.
In short, Polyquaternium-4 is like a tool in the hands of skilled craftsmen in cosmetics. Although invisible, it is crucial to add color to cosmetics and help them play better effects.

Does Polyquaternium-4 have side effects on the skin?
Today there are questions about whether polyquaternium-4 has side effects on hair. This polyquaternium-4 is often an ingredient used in hair care. In the field of hair care, its function is quite significant.
Looking at its properties, it has excellent film-forming properties. When applied to the hair, it can form a uniform protective film, smoothing the surface of the hair, reducing its friction, making the combing smoother, and increasing the luster of the hair, just like covering the hair with a colorful coat.
As for side effects, usually speaking, when used in moderation, obvious harm is rarely seen. However, if the individual skin or scalp is sensitive to it, it may occasionally be sensitized. When allergic, or the scalp may be itchy, red and swollen, although this is rare, it cannot be ignored.
Furthermore, if the content of polyquaternium-4 in the product is too high, or the hair is too thick and sticky, as if the hair is bound by a heavy object, it loses its light and flexible state.
Therefore, when using hair care products containing this ingredient, pay attention to the reaction of your own skin and hair. If there is any discomfort, stop using it to ensure the health of the hair and scalp.
