Sodium Alpha-Olefin Sulfonate (AOS) is a highly effective anionic surfactant sought after for its excellent cleaning, foaming, and emulsifying properties. Manufacturers and formulators often face a choice between the powder and liquid forms of AOS, each offering distinct advantages depending on the specific application and processing capabilities. As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides both high-purity AOS powder (typically 92% active) and concentrated liquid AOS (around 30-35% active) to cater to diverse industry needs.

Understanding the Forms of AOS: Powder vs. Liquid

  • AOS Powder (≥92% Active):
    The powder form of AOS offers a highly concentrated active ingredient, making it extremely efficient for transportation and storage. It is ideal for formulators who have the capability to handle solid materials and can accurately incorporate them into their liquid or solid product matrices. The high active content means less material is needed to achieve the desired effect, potentially leading to cost savings in formulation. However, it requires careful handling to avoid dust and clumping, and complete dissolution can take longer than with liquid forms.
  • AOS Liquid (≥30-35% Active):
    Liquid AOS offers convenience in handling and ease of incorporation into aqueous systems. It is typically easier to dose accurately and dissolves quickly, streamlining the manufacturing process. This form is particularly advantageous for formulators who have limited solid handling equipment or who are developing products that are already liquid-based. While it has a lower active concentration than powder, its ease of use can offset this in many applications.

Factors to Consider When Choosing:

  • Application Requirements: For dry mixes or formulations where water content is a concern, powder AOS is often preferred. For liquid formulations where easy integration is key, liquid AOS is ideal.
  • Processing Equipment: If your facility is equipped for solid handling and dispersion, powder AOS can be very cost-effective. If you primarily work with liquid raw materials, the liquid form simplifies your operations.
  • Storage and Logistics: Powder AOS generally has a longer shelf life and is more concentrated by volume, which can be advantageous for shipping and storage. Liquid AOS may require more careful temperature control to prevent freezing or degradation.
  • Cost-Effectiveness: While powder AOS has a higher active content per kilogram, the overall cost-effectiveness also depends on ease of handling, dissolution rates, and the final formulation cost.
