Countertype or Equivalent:

Specification:
Appearance: Light yellow transparent liquid Content: 99%
PH value: 4-7
Moisture: 0.5%
Sodium Bromide: ≤0.5%

Application:
Product Usage:
Biocides are mainly used in industrial circulating water, papermaking pulp, coatings, plastics, cosmetics, wood, cooling water circulation systems, as well as for sterilization, mildew prevention, anticorrosion, and algae killing for industrial purposes.

advantage:
(1) High efficiency, with broad-spectrum antibacterial activity, it can inhibit the growth of most bacteria at a concentration of 25ppm, and has better effect on Gram-negative bacteria and various Pseudomonas;
(2) The dosage is small and the price is low. In cosmetics, the dosage is generally 0.01~0.05%, which is one-tenth of the commonly used preservatives of parabens in cosmetics, and the cost of use is more than half cheaper than that of parabens;
(3) Good compatibility. Nutrients such as protein and various cationic, anionic and nonionic surfactants will not affect its bacteriostatic effect;
(4) Appropriate pH range. It is effective in the pH range of 4 to 9, that is, in weakly acidic, neutral and alkaline environments, it can maintain a strong bacteriostatic effect after adding it;
(5) Good water solubility and easy to use. It is easy to dissolve in water, the solubility in water is 25g at 25°C, and it is extremely convenient to use.

Use range and addition amount:
This product can be used in creams, lotions, shampoos and other products. The general addition amount is 0.2-0.5‰, and the maximum allowable addition amount in daily chemical products is 1‰. There is no residue in the discharge and will not cause cumulative pollution to the environment. Application PH value range: 4-8; Application temperature range: generally pre-dissolved in an appropriate amount of water and added below 60 °C.

Precautions:
This product can be used in a wide range of PH, with the best acid to neutral range. It is unstable under high temperature and alkaline conditions, and darkens in color under sunlight. Compatible with most surfactants, but when there are substances containing -SH group in cosmetic raw materials, such as cysteine, etc., their antibacterial activity will be reduced. In addition, metal aluminum can also reduce the antibacterial activity of this product.

Packing:
Packing: 25kg bag.
Storage conditions: This product is stored in a cool and dry environment, and cannot be mixed with toxic and harmful substances.

Safety:
Hazard Classification 4.1
