POLYQUATERNIUM-51Polyquaternium-51 (Polyquaternium-51) chemical name: methacryloxyethyl phosphorylcholine-n-butyl methacrylate, is a synthetic bionic material of cell membrane structure, with phospholipids in the cell membrane The polar group of acylcholine is a copolymer composed of 2-methacryloyl hydroxyethyl phosphatidylcholine (MPC) and monomeric hydrophobic butyl methacrylate. Polyquaternium-51 has super moisturizing properties, its moisturizing properties are twice that of hyaluronic acid, and can alleviate the irritation of surfactants, so it is widely used in cosmetic moisturizer raw materials and medical aesthetics.

Polyquaternium-51 is an efficient and mild moisturizing factor with excellent water-locking and moisturizing properties. It can effectively lock the moisture of the skin and hair, and its moisturizing properties will not be reduced after multiple washings. After the product containing polyquaternium-51 is applied, its ingredients can form a respirable biofilm on the surface of the skin, which simulates the stratum corneum to give the skin an extra layer of protection, effectively inhibits the irritation of surfactants on the skin, and can Improve rough skin, smooth and delicate skin, and enhance the skin's absorption of active ingredients.

1. Super moisturizing function

Polyquaternium-51 is a new polymer moisturizer, its moisturizing effect is twice that of hyaluronic acid. In addition, its biggest feature is that after application, even after washing, it will not reduce its moisturizing effect. Moisture absorption and moisturizing properties. It has a good moisturizing effect on dry skin and hair. After polyquaternium-51 acts on the skin surface, the high molecular weight components can form a stable hydration gel film on the skin surface, and then form a second layer of protection and water retention on the skin's own epidermal barrier. Keep the skin moisturized and elastic.

2. Alleviate the irritation of surfactants

Surfactants are an important component of cleansing cosmetics that people use daily. While removing dirt on the surface of the skin, it will also cause certain irritation to the skin, weaken the skin's natural protective barrier, and cause dry skin and scaly. The cell-like membrane structure of Polyquaternium-51 can alleviate and inhibit the irritation of surfactants to the skin, restore the vitality of skin cells, effectively repair the damaged protective barrier, and keep the skin bright and moist.

3. Enhance skin's absorption of active ingredients in cosmetics

Polyquaternium-51 can form nanomicelles with a cell-like membrane structure, encapsulate various nutrients that are difficult to pass through skin barriers, enhance the permeability of active ingredients to the skin stratum corneum, and prevent various active factors Such as vitamin C, vitamin E, amino acids, superoxide dismutase (SOD) oxidation deterioration, to achieve deep and long-lasting skin care, strengthen cosmetics to nourish the skin, improve skin conditions and prevent skin diseases.
