China and the United States are the leading exporters of Sodium dodecyl sulfate (CAS 151-21-3), collectively accounting for over 40% of global export value in 2023–2024, while India, Germany, and South Korea rank among the top importers. Import volumes in Southeast Asia and Latin America have risen steadily since 2022, coinciding with moderate upward pressure on Sodium dodecyl sulfate prices amid tightening supply chains and increased demand from detergent and pharmaceutical manufacturing.
Market Dynamics Intelligence for Sodium Dodecyl Sulfate (SDS)
I. Price Trends
1. Domestic Market:
- East China: The price range for industrial-grade SDS is 9,800-10,200 CNY/ton, up 1.2% week-on-week, primarily driven by rising costs of the raw material dodecanol.
- South China: Prices remain stable at 9,600-9,900 CNY/ton, with some companies slightly increasing quotes due to low inventory levels.
- North China: Price fluctuations are minimal, with mainstream transaction prices ranging from 9,500-9,800 CNY/ton, driven mainly by essential downstream demand.
2. International Market:
- Southeast Asia: CIF prices have risen to 1,350-1,400 USD/ton, influenced by reduced exports from China and increased demand from India.
- Europe and the US: Prices remain stable at 1,450-1,500 USD/ton; however, some suppliers in Europe have hinted at potential future price increases due to rising energy costs.
II. Supply and Demand Dynamics
1. Supply Side:
- Domestic capacity utilization is approximately 75%. Some companies have reduced production due to environmental restrictions or equipment maintenance. For example, a plant in Zhejiang has suspended operations for 10 days, affecting monthly output by approximately 800 tons.
- Imports have decreased by 15% month-on-month, mainly due to reduced supply from Southeast Asia and increased international shipping costs.
2. Demand Side:
- Daily Chemical Industry: Terminal demand for detergents, shampoos, and other products remains stable. However, influenced by seasonal factors, demand in northern regions is slightly weaker than in southern regions.
- Industrial Sector: Demand in the textile and construction materials industries has grown moderately. Some companies have strengthened their stocking intentions, driving a short-term increase in procurement volumes.
III. Costs and Profits
1. Raw Material Costs:
- Dodecanol prices have risen to 12,500-13,000 CNY/ton, an 8% increase month-on-month, directly increasing the production cost of SDS by approximately 500 CNY/ton.
- Prices for auxiliary materials such as sulfuric acid and liquid caustic soda have shown minimal fluctuations, with limited impact on overall costs.
2. Profit Margins:
- The industry's average gross margin has compressed to 12%-15%. Some small and medium-sized enterprises have suspended order acceptance due to cost pressures, leading to a reduction in low-priced market supply.
IV. Relevant Policies and Industry Trends
1. Environmental Policies:
- Many regions in China have strengthened the control of VOCs emissions from chemical enterprises. Some companies need to upgrade their waste gas treatment equipment, limiting short-term capacity release.
2. Industry News:
- The Indian government has launched an anti-dumping investigation on imported SDS, which may affect China's export volume to India.
- A leading domestic company plans to add 50,000 tons/year of production capacity, expected to come online in Q2 2024, which may alleviate long-term supply pressure.
V. Analysis and Forecast
1. Short-term (1-2 weeks):
- Prices are expected to remain stable with a slight upward bias. This is mainly due to the firm price of the raw material dodecanol and the continued impact of supply-side production cuts. Supported by essential downstream demand, prices in East China and South China may see tentative increases of 50-100 CNY/ton.
2. Medium-term (1-3 months):
- If the Indian anti-dumping investigation concludes, China's export volume to India may decrease by 30%-40%. The Southeast Asian market will likely absorb part of this demand, pushing international prices higher.
- Before new domestic production capacity comes online, the tight supply situation is unlikely to change, and prices may remain at high levels with fluctuations, expected in the range of 9,800-10,500 CNY/ton.
3. Long-term (3-6 months):
- After the release of new production capacity, increased market supply may put downward pressure on prices. However, attention must be paid to the price trends of the raw material dodecanol and the intensity of environmental policy enforcement.
- If daily chemical industry demand exceeds expectations (e.g., stocking for e-commerce promotional seasons), prices may receive phased support.
VI. Risk Warnings
1. Risk of significant fluctuations in dodecanol prices.
2. Uncertainty regarding the outcome of the Indian anti-dumping investigation.
3. Potential supply contraction due to further tightening of domestic environmental policies.
Sodium dodecyl sulfate (SDS) is a white to off-white crystalline powder or granular solid with a faint, characteristic odor; it is non-volatile, water-soluble, and has a melting point of approximately 204–207 °C (with decomposition). It is an anionic surfactant and organic sulfate ester, classified as a synthetic detergent and amphiphilic molecule. SDS is widely used in industrial cleaning formulations, personal care products (e.g., shampoos, toothpastes), and laboratory applications—particularly in electrophoresis as a protein denaturant and charge provider. It serves as a key processing aid and emulsifier in pharmaceuticals, agrochemical formulations, textile auxiliaries, and polymer emulsion production.
Sodium dodecyl sulfate has excellent detergency, emulsification and foaming power, can be used as detergents and textile auxiliaries, and is also used as an anionic surfactant, toothpaste foaming agent, mine fire extinguishing agents, foaming agents for fire extinguishers, emulsion polymerization emulsifiers, emulsifying and dispersing agents for medical use, shampoo and other cosmetic products, wool detergent, detergent for silky class fine fabrics and flotation agent for metal beneficiation. GB 2760-96 stipulates as processing aids for food industry. It used as foaming agents; emulsifying agents; and anionic surfactants. It is used for cakes, drinks, proteins, fruits, fruit juice, and edible oil, and so on. It is used as surfactants, detergents, foaming agents, and wetting agents, and so on.It is used as relatively low-level ion-pairing reagents, and is cheaper than sodium heptanesulfonate and sodium pentanesulfonate when less demanding.It is used as raw material for modifying materials.It is used as additives in capillary electrophoresis analysis and is generally used as molar solution.It is also used in other analysis such as flow column analysis.
