Introduction:
Zinc PCA is a product that combines zinc with the natural moisturizing factor "pyrrolidone carboxylic acid (PCA)".
The full name of PCA is pyrrolidone carboxylic acid (converted from glutamic acid). It itself exists in the stratum corneum and is an important component of the natural moisturizing factor (NMF) inherent in the skin. NMF can bind moisture in the stratum corneum, keeping the skin soft and smooth and maintaining a healthy barrier.
Therefore, zinc PCA not only has the antibacterial, anti-sebum secretion, and anti-inflammatory effects of zinc, but also has the function of retaining moisture in the stratum corneum and maintaining a healthy barrier because it contains PCA. PCA zinc is used as a cosmetic raw material and is very safe and has good antibacterial and astringent properties.

main effect:
Oil-controlling factors can shrink pores, balance oil secretion, prevent skin from becoming oily, and increase skin's luster. Leaves hair and skin feeling soft, smooth and fresh.
Zinc pyrrolidone carboxylate is used to control excessive sebum secretion. As an anti-acne agent, it can balance sebum secretion, greatly reduce the problem of facial shine, and prevent the occurrence of future acne; it regulates the skin and maintains skin moisture, and refines pores. , prevent pores from being blocked and effectively prevent acne; it also has anti-bacterial and fungal effects. Can be used in skin care, hair care, sunscreen products, makeup, etc.
The zinc salt form of pyrrolidone carboxylic acid (PCA), which is the cyclide of L-pyroglutamic acid. PCA zinc can stimulate the differentiation of epidermal cells, enhance skin barrier function, and maintain skin moisture; inhibit excessive secretion of oil and act as an anti-oil and anti-seborrheic agent; inhibit bacterial proliferation and act as an antibacterial agent. PCA zinc is suitable for oil control, anti-acne and other products, and is suitable for oily skin. PCA zinc has the effect of controlling oil and removing acne. It can control acne and blackheads by controlling the secretion of oil by sebaceous glands.
1. The process of sebaceous glands secreting sebum is called seborrhea. Sebum keeps the skin and hair flexible and fresh, while also protecting the skin from external aggressions. Sebum is very important for maintaining the balance of skin and hair.
2. Excessive secretion of sebum will lead to unsightly shiny, greasy and uncomfortable skin, and is often accompanied by the proliferation of bacterial flora, especially acne bacilli that grow in the pores. The bacterial growth causes pain and, in some cases, inflammation.
3. PCA zinc can also inhibit Propionibacterium acnes, lipase and oxidation, thereby reducing irritation, soothing inflammation and preventing acne formation.
4. Zinc. It is an important component of various enzymes in the skin. It can promote wound healing and skin renewal, restore normal cell functions, enhance the skin's immune system, reduce oil secretion, inhibit bacteria, reduce skin inflammation, and make the skin firmer. In skin care products, zinc mainly exists in these forms: zinc gluconate, zinc PCA, zinc phenolsulfonate, zinc sulfate, and zinc lactate.
use
The recommended addition amount is 0.1-3%, and the ideal pH value is 5.5-7.0
The recommended dosage is 0.3% in lotion and 0.2%~0.5% in shampoo or cleansing gel.
resolve resolution:
1. L-glutamic acid is heated to dehydrate the ring and prepare L-pyrrolidone carboxylic acid;
2. Using water as the medium, L-pyrrolidone carboxylic acid reacts with zinc carbonate or basic zinc carbonate at 0 to 100°C;
3. Cool and crystallize the reaction product obtained in step 2, and filter, wash and dry the crystals to obtain zinc L-pyrrolidone carboxylate.

The zinc pyrrolidone carboxylate market research report focuses on the global (Europe, North America, Asia Pacific, Middle East, Latin America, Africa, etc.) and China (key regions such as North China, South China, East China, and China) for analysis.
In addition, PCA zinc is also used as an oil-controlling ingredient and can be used as a skin conditioner. It works on a different principle than oil-absorbing ingredients. It mainly inhibits oil secretion and refreshes the skin. This substance is composed of zinc ions and pyrrolidone carboxylic acid (PCA). Studies have shown that after using zinc-containing lotion for 12 weeks, it can reduce oil secretion by about 20%, and the effect is very significant.
Pyrrolidone carboxylic acid is a component of the skin's natural moisturizing factor, not to mention its moisturizing effect. The powerful combination of these two substances perfectly solves the problem of skin peeling while controlling oil.
The difference between PCA sodium and PCA zinc
Sodium PCA is a natural moisturizing factor, which mainly has moisturizing effect;
Because PCA zinc contains zinc ions, in addition to its moisturizing effect, it also has oil control and astringent effects. Oil control is by regulating the secretion of pilosebaceous glands, and convergence is by stimulating the contraction of arrector pili muscles;
From a structural point of view, the only difference between them is the difference in metal. This difference leads to different functions.
