Description

Sulfonic Acids, C10-18-Alkane, Ph Esters are a class of anionic surfactants derived from the esterification of phenyl sulfonic acids with a C10-18 alkane chain. This compound is valued for its excellent wetting, emulsifying, and detergent properties, making it a versatile intermediate and additive. It is primarily needed by manufacturers in the industrial cleaning, agrochemical, textile, and personal care industries for formulating high-performance products.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a powerful wetting agent and emulsifier in heavy-duty degreasers, acid cleaners, and metal treatment formulations.
• Agrochemicals: Used as an adjuvant in pesticide and herbicide formulations to enhance spreading, penetration, and overall efficacy on target surfaces.
• Textile Processing: Serves as a scouring agent, dye leveling agent, and wetting agent in various stages of textile manufacturing and finishing.
• Personal Care & Cosmetics: Functions as a surfactant and cleansing agent in specialized skin and hair care products, requiring specific ester grades.
• Emulsion Polymerization: Employed as an emulsifier and stabilizer in the production of synthetic rubbers, polymers, and latexes.
• Oilfield Chemicals: Utilized in drilling muds and other oilfield applications as a surfactant and demulsifier.
• Leather Processing: Aids in the wetting and penetration of fats, dyes, and tanning agents during leather production.

Quality Control

Our Sulfonic Acids, C10-18-Alkane, Ph Esters undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Quality parameters are monitored against strict internal specifications. Certificates of Analysis (COA) detailing assay, purity, and key physical-chemical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from strong bases and oxidizing agents. Due to its strong acid/organic solvent nature, ensure containers are made of compatible materials (e.g., HDPE, stainless steel). Recommended storage temperature is 15-25°C.
