How does XK-PHMB Polyhexamethylene Biguanide Hydrochloride work as a preservative?

In the manufacturing and storage of cosmetics, it is crucial to prevent the contamination and growth of microorganisms. In order to achieve this goal, various preservatives are widely used in the cosmetics industry. Among them, XK-PHMB (Polyhexamethylenebiguanide Hydrochloride) is favored by the industry as an efficient and safe preservative.

1. Basic characteristics of XK-PHMB
XK-PHMB, full name polyhexamethylene biguanide hydrochloride, is a high molecular polymer. With its unique chemical structure and good physical and chemical properties, it shows good performance in the field of cosmetic preservation. XK-PHMB has a broad-spectrum antibacterial property and can effectively inhibit the growth of bacteria, fungi and viruses, thereby ensuring the quality and safety of cosmetics.

2. XK-PHMB's preservative mechanism
Destroy microbial cell membranes: XK-PHMB can interact with the cell membranes of microorganisms, destroy their integrity, cause the leakage of intracellular substances, and then inhibit the growth and reproduction of microorganisms.

Interference with microbial metabolism: In addition to destroying cell membranes, XK-PHMB can also interfere with the metabolic process of microorganisms, inhibit their key life activities such as energy production and biosynthesis, and further weaken the activity of microorganisms.
Efficient and long-lasting: XK-PHMB has an efficient and long-lasting antibacterial effect, and can maintain stable preservative properties in cosmetics for a long time. This is due to its stable chemical structure and good compatibility with cosmetic ingredients.

3. Application of XK-PHMB in cosmetics
Adding XK-PHMB to cosmetics can effectively prevent the contamination and growth of microorganisms. Whether it is in the raw material, semi-finished product or finished product stage of the production process, XK-PHMB can play an good preservative role. In addition, XK-PHMB also has good stability and safety, and will not affect the texture, color and fragrance of cosmetics, nor will it cause irritation or damage to the skin.
