What is Alpha Olefin Sulfonate and what are its primary properties?
Alpha Olefin Sulfonate (AOS) is a mild anionic surfactant known for its high foaming and emulsifying properties. It is primarily derived from coconut oils and is a 40% active solution, which is stable across a wide pH range, allowing it to be used in both neutral and acidic formulations. AOS is recognized for its excellent cleansing and degreasing properties while being non-drying to skin and mucous membranes. It also serves as a foam booster and has slight viscosity-enhancing capabilities. This surfactant is easily compatible with a variety of other surfactants, including non-ionic, amphoteric, and anionic co-surfactants. It is particularly noted for its effectiveness in developing sulfate-free cleansing products.
What are the applications of AOS-40?
AOS-40, a pale yellow 40% aqueous solution of sodium C14-16 alpha olefin sulfonate, is versatile and can be used in various applications. It is ideal for economical and high-performing sulfate-free biodegradable shampoos, hand soaps, shower gels, car washing compounds, light-duty liquid detergents, and heavy-duty laundry detergents. The product's compatibility with other surfactants and its stability across a broad pH range make it highly adaptable for different formulations, including those incorporating alpha hydroxyl acids or salicylic acid.
Why is AOS-40 considered beneficial for formulators?
AOS-40 offers numerous advantages, making it highly beneficial for formulators. It provides excellent cost/performance characteristics and foam properties, which are often superior to that of lauryl sulfates. Its improved mildness and stability over a wide pH range, combined with its excellent viscosity and foam characteristics, allow for greater flexibility in product formulation. This surfactant is also fully compatible with other anionic, amphoteric, and nonionic surfactants, enhancing its applicability across various product types.
Is Alpha Olefin Sulfonate environmentally friendly?
Yes, Alpha Olefin Sulfonate is considered environmentally friendly. It is readily biodegradable, which makes it an attractive option for formulators seeking sustainable and environmentally conscious solutions. Its formaldehyde-free composition and excellent thermal stability further extend its use in environmentally friendly applications, such as in sulfate-free personal care and detergent products.
How does AOS-40 compare to lauryl sulfates in terms of mildness?
AOS-40 is milder compared to traditional lauryl sulfates. This mildness is an important factor for personal care products as it allows for effective cleansing without causing dryness or irritation to the skin and mucous membranes. Its unique composition makes it a preferred choice for sulfate-free formulations, providing both efficacy and gentleness in one solution.
