Product Introduction】Katho n or Katho n, as the trade name, has the characteristics of broad-spectrum efficiency, low toxicity, safety to the environment, no allergy to human body, etc. It can inhibit and kill bacteria, fungi, yeasts and other bacteria. It is a broad-spectrum bactericidal preservative above *, and can be used in cream, lotion, shampoo, hair conditioner, children's cosmetics and eye cosmetics. useCosmetic preservative Kaison analysis gas chromatography,FPD detectorThe measurement is characterized by simplicity, speed, high sensitivity, and strong specificity

【 Analysis Principle 】Kaisong light yellow liquid, a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one (CIT) and 2-methyl-4-isothiazolin-3-one (MIT) (3:1). Based on its solubility in water, lower alcohols, and insolubility in oil, it can be directly extracted with methanol. Extract Kaisong from cosmetics using methanol, as its molecular structure contains S, using gas chromatography with FPD detector (S filter, 393nm) detection, qualitative retention time, and quantitative peak area.
