Preservative Kathon CG (Isothiazolinone, CAS 55965‑84‑9) is a broad‑spectrum antimicrobial agent widely used in household chemistry. The active ingredient is a blend of methylisothiazolinone (0.05–0.3 %) and chloromethylisothiazolinone (1.5 %). At a dosage of 2–9 mg L⁻¹ it delivers up to 99 % microbial protection in aqueous systems and remains stable across a pH range of 4–9. Because of its high stability in alkaline environments, Kathon CG is preferred for shampoos, creams, detergents and water‑based paints where long‑term product shelf life is required. The isothiazolinone core disrupts microbial cell membranes, providing rapid biocidal action against bacteria, yeasts and molds, which makes it suitable for a wide range of personal‑care, cleaning and industrial coating formulations. In practice it is often paired with non‑ionic or anionic surfactants and can be used together with other preservatives such as phenoxyethanol to achieve synergistic protection and reduce the risk of resistance development. Typical usage levels vary: cosmetic and personal‑care products usually contain 0.01–0.1 % Kathon CG, while industrial cleaners may incorporate up to 0.2 % depending on the required preservation period. Handling recommendations include wearing chemical‑resistant gloves and eye protection, and ensuring adequate ventilation, as isothiazolinones can cause skin and eye irritation upon direct contact. Recommended storage is a dry, cool area (5 °C‑25 °C) away from direct sunlight. Shelf life under proper conditions is 24 months. The Rohm & Haas brand guarantees purity; each shipment is accompanied by complete technical documentation – TDS, SDS and a Certificate of Analysis (COA).

Store Kathon CG in a dry, cool environment, shielded from direct sunlight and heat sources. Recommended storage temperature is between +5 °C and +30 °C, provided the container remains intact. When sealed, the typical shelf life is about 24 months. Use protective gloves and goggles during handling, avoid inhalation of vapors and skin contact. Ensure packaging integrity during transport and storage to prevent moisture ingress and contamination.
