Sodium C14-16 Olefin Sulfonate (AOS, CAS 68439-57-6) is a widely used olefin sulfonate detergent raw material valued for its strong cleaning properties. AOS is an anionic surfactant used in many household and industrial cleaning formulations. It is especially popular for cleaning products because it is phosphate-free and readily biodegradable. For example, AOS generates stable foam and excellent detergency in shampoos, laundry detergents, and surface cleaners. Its compatibility with hard water and mildness on skin make it ideal for consumer products. Key application sectors include:

• Personal Care & Cosmetics: Shampoos, body washes, hand soaps and other bath products. AOS creates rich lather and helps remove oils and makeup without irritating skin.

• Household Cleaning: Liquid and powder detergents, dishwashing liquids, and surface cleaners. AOS’s foaming and emulsifying actions improve removal of grease and soils.

• Industrial Cleaning: Heavy-duty cleaners and degreasers in metalworking, automotive, and textile processing. AOS effectively emulsifies oils and protects equipment by preventing redeposition of grime.

• Agricultural Formulations: Wetting agent in pesticide and herbicide sprays. AOS reduces water surface tension to help agrochemicals spread evenly on plant surfaces.

AOS is a phosphate-free surfactant, making it a key ingredient in eco‑friendly cleaning products. Unlike older phosphate detergents, AOS formulations do not contribute to water eutrophication. Importantly, AOS is readily biodegradable under aerobic conditions. Laboratory studies confirm that it breaks down efficiently in the presence of oxygen, aligning with stringent environmental regulations. Additional eco-benefits include:

• Phosphate-Free & Green: Eliminates the environmental harm associated with phosphate detergents.

• High Biodegradability: Studies show AOS decomposes quickly in aerobic environments.

• Hard-Water Performance: Unlike some surfactants, AOS remains effective in hard water (high Ca/Mg), avoiding scale formation. This means lower detergent use and less chemical residue.

Together these features make AOS a preferred raw material for sustainable cleaning and personal care formulations.

Global demand for AOS is rising steadily. Reports highlight Asia-Pacific (especially China) as the largest and fastest-growing market segment. Verified Market Reports notes Asia Pacific holds roughly 40% of the world’s AOS market in 2023, driven by booming personal care and industrial sectors. Europe and North America are also major markets; both regions are seeing steady growth in demand. For example, one industry study predicts North America will remain the leading AOS market, with Europe second, while Asia-Pacific registers the fastest growth rate. Key regional highlights:

• Asia-Pacific (China): Dominant market share (~40% in 2023) and fastest growth. Demand is fueled by rising income, expanding home care and personal care industries, and government support for local chemical production.

• Europe: Second-largest market. Adoption is driven by high consumer awareness and strict eco-regulations favoring biodegradable surfactants. The EU’s push for phosphate-free cleaning agents bolsters AOS use.

• North America: Strong demand in household and industrial cleaners. Often cited as a top market by value. Growth is supported by consumer preference for “green” ingredients and industrial cleaning needs.

Emerging regions (Latin America, Middle East/Africa) are also experiencing rapid AOS market growth. Overall, rising global emphasis on sustainability and multifunctional cleaners is expanding AOS demand worldwide.

China has become a global production hub for AOS, thanks to its large petrochemical industry and manufacturing capacity. Industry analyses note that Asia-Pacific – led by China – “leads the global Sodium C14-16 Olefin Sulfonate market, with robust domestic demand, supportive policies, and a strong manufacturing base.” In practice, China supplies a significant portion of the world’s AOS. Chinese producers benefit from integrated supply chains (from fatty alcohol feedstock to surfactant synthesis) and economies of scale. As a result, many international buyers turn to Chinese exporters for reliable AOS supply.

Chemfine International Co., Ltd. (ChemFine) exemplifies the strength of China’s AOS supply chain. Since 2003, Chemfine has specialized in sourcing and exporting fine chemicals from China. Key advantages of Chemfine’s AOS offering include:

• Stable Export Capacity: As a seasoned China AOS exporter, Chemfine works with 60+ collaborating plants across China to ensure large-volume, steady shipments. This network guarantees continuity of supply even during peak demand.

• Certified Quality Control: Chemfine maintains a rigorous quality management system (ISO 9001 certified). All AOS products undergo strict quality inspections (MSDS, REACH testing, etc.), ensuring consistent high purity and performance.

• Flexible Packaging & Small Batches: Chemfine supports customized packaging and small-batch orders to meet diverse customer needs. This flexibility is valuable for specialty chemicals buyers or new product developers.

• International Credentials: The company holds global certifications (ISO9001, ISO14001, OHSAS18001) and complies with international trading standards. Chemfine also handles FOB/CIF shipments from nearby ports, streamlining logistics.

• Comprehensive Service: With offices and partners worldwide, Chemfine offers technical support and documentation for overseas buyers. Customers benefit from competitive FOB pricing and quick response to inquiries.

By combining China’s cost and scale advantages with reliable service, Chemfine International has become a trusted Sodium C14-16 Olefin Sulfonate supplier and AOS CAS 68439-57-6 manufacturer for global markets. Their long-standing reputation (Jiangsu-authorized trading company since 2003) and focus on quality make them a strong partner for detergent and personal care producers.
