Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9

1. Butylnaphthalenesulfonic acid sodium salt is primarily used as an anionic surfactant with excellent penetration, wetting, emulsifying, dispersing, and foaming properties in textile printing and dyeing processes .
2. Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9 serves as a versatile processing aid in industrial applications, functioning as a dispersant for thermal paper, an emulsifier for emulsion polymerization, and a wetting agent in agrochemical formulations .
3. Butylnaphthalenesulfonic acid sodium salt is employed as a detergent, dyeing aid, dispersant, and as an additive in insecticides and herbicides .
4. In chemical manufacturing, Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9 is resistant to acid, alkali, hard water, and inorganic salts, and its permeability is significantly enhanced when mixed with small amounts of salt .

1. Butylnaphthalenesulfonic acid sodium salt must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; commercially available as a 40% aqueous solution, it should be stored at room temperature in a cool, dark place (below 15°C) .
2. Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9 is classified as a dangerous substance with GHS signal word "Danger" and hazard statements H302 (Harmful if swallowed), H315 (Causes skin irritation), H318 (Causes serious eye damage), H332 (Harmful if inhaled), and H335 (May cause respiratory irritation) .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, face protection, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9 away from incompatible materials such as strong oxidizing agents; the compound has WGK Germany 3 classification (high water hazard potential) and should not be released into the environment .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Butylnaphthalenesulfonic acid sodium salt is released .
2. For Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9 spills (40% aqueous solution), contain and collect the product using inert absorbent materials such as sand, diatomite, or universal binders with non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating vapors or mists during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses due to aquatic toxicity .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Butylnaphthalenesulfonic acid sodium salt is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and sulfur oxides .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Butylnaphtalenesulfonic Acid Sodium Salt CAS 25638-17-9 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Butylnaphthalenesulfonic acid sodium salt due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
