Sodium Alpha-Olefin Sulfonate Aos 35% Aos 92% Powder CAS 68439-57-6 for Detergent Sodium Alpha-Olefin Sulfonate (AOS) is a versatile surfactant widely used in various industries. It is available in both liquid and powder forms, offering high active content and excellent performance. As an anionic surfactant, AOS is a key ingredient in detergents, personal care products, and industrial cleaning applications, and it is known for its strong foaming ability, effective cleaning power, and mildness.
AOS is valued for its ability to provide excellent emulsifying, wetting, and dispersing properties, making it an ideal choice for formulations requiring stable foams and superior dirt removal. It is commonly used in shampoos, body washes, dishwashing liquids, and industrial cleaners.
Liquid AOS typically has an active content of ≥ 30%, while the powder form generally has an active content of ≥ 92%. Both forms deliver exceptional performance in both hard and soft water, offering stable foam and excellent cleaning efficacy.
Produced through the sulfonation of α-olefins, AOS is a safe and biodegradable material, making it suitable for use in a wide range of personal care, home care, and industrial cleaning products.

Common Applications of AOS Liquid and Powder:
- Detergents and Cleaning Products: Both liquid and powder forms of AOS are widely used in laundry detergents, dishwashing liquids, and industrial cleaners for their excellent foaming, cleaning, and emulsifying properties.
- Personal Care Products: In shampoos, body washes, and facial cleansers, AOS in both forms acts as a surfactant that provides effective cleansing and foaming while being gentle on the skin and hair.
- Oilfield Applications: Both forms are used as emulsifiers and wetting agents in oil extraction and drilling processes, helping to improve oil recovery and efficiency.
- Agriculture: AOS is used in pesticide formulations in both forms, improving the spreading, wetting, and penetration of the active ingredients in the soil or plant surfaces.
- Textile Industry: Both liquid and powder AOS serve as surfactants in the textile industry, enhancing cleaning and fiber penetration to aid in fabric scouring, dyeing, and finishing.
Differences Between AOS Liquid and Powder:
Ease of Use in Formulation:
- Liquid AOS: The liquid form is easier to dissolve and incorporate directly into formulations, making it ideal for products that require quick mixing, such as liquid detergents, body washes, and industrial cleaners. It can be directly added to the production process.
- Powder AOS: The powder form requires dissolution in water or other solvents before use. It is typically preferred in dry applications, such as powdered detergents or solid cleaning products. It also allows for more precise control over concentration.
Application in Different Manufacturing Processes:
- Liquid AOS: It is often used in processes that require the surfactant to be easily blended with other ingredients. For example, the liquid form is directly incorporated into the product base in shampoo or liquid soap production.
- Powder AOS: This form is more suitable for products that are prepared in bulk or require controlled dosing. It's ideal for making solid or granular formulations where the AOS needs to be measured out before use.
Storage and Handling:
- Liquid AOS: The liquid form requires special packaging to avoid leakage and ensure safe transport. It may also need to be stored in containers that prevent contamination or degradation.
- Powder AOS: Being in solid form, the powder is generally easier to handle and store in bulk, with fewer concerns about leakage or spoilage. It's more stable during transport and storage.
Summary:
- Common Use: Both liquid and powder AOS serve the same core functions, foaming, emulsifying, and surfacing in a variety of industries such as personal care, detergents, oilfield applications, and agriculture.
- Differences: The main differences lie in their physical forms and ease of incorporation into different types of formulations. Liquid AOS is often preferred for easy mixing in liquid-based products, while powder AOS is used for dry applications and bulk production, offering more control over concentration and dosage.
