Factors Affecting the Preservative kathon
1. PH value: When the pH value is greater than 9 in an alkaline medium, it will affect the stability of kathon
2. Temperature: 5.5% failure rate for 10 minutes at 50°C, 6.3% failure rate for 30 minutes; 6.2% failure rate for 10 minutes at 100°C, 8.1% failure rate for 30 minutes; The failure rate at 10 minutes was 9.0% and the failure rate at 30 minutes was 15.9%.
3. Monovalent sodium ions and potassium ions have no effect on the stability of Kathon; divalent magnesium ions, calcium ions, and copper ions have a protective effect on the stability of Kathon. ions, calcium ions; ferric ions have a damaging effect on the stability of kathon, so it should not be in contact with reducing metals during storage, such as metal iron, aluminum, etc., to avoid product decomposition.
4. Chemicals with strong nucleophilicity are compatible with this product, mercaptans, amines, thioethers, thiosulfates, strong reducing agents (sodium sulfite and bleach), such as S2- and R-NH2, will cause this product. The quality of the product is degraded, or even completely invalid.
