Product Introduction

Alkyl Sulfonate SAS, also known as Secondary Alkane Sulfonate, is an anionic surfactant commonly used in various cleaning and personal care products, characterized by its excellent detergency, emulsifying, dispersing, wetting, and foaming properties [1]. It is synthesized through sulfonation of n-paraffins, a process that results in a mixture of isomers, which contributes to its unique performance characteristics [2]. The compound is biodegradable, making it an environmentally conscious choice for formulations [3].

Production Process

The industrial production of Alkyl Sulfonate SAS typically involves the sulfonation of n-paraffins with sulfur trioxide (SO3) or oleum, followed by neutralization with a base, such as sodium hydroxide [4]. The sulfonation reaction introduces a sulfonic acid group (-SO3H) onto the alkane chain, and subsequent neutralization converts the sulfonic acid to its salt form, commonly sodium alkyl sulfonate [5]. Purification steps are often included to remove unreacted materials and byproducts, thus improving the quality and performance of the final product [6].

Efficacy and Function

Alkyl Sulfonate SAS excels in reducing surface tension, enabling it to effectively remove dirt and oil from surfaces [7]. Its emulsifying properties allow the stabilization of mixtures of oil and water, which is crucial in cleaning formulations [8]. The product also demonstrates good foaming ability, contributing to the sensory appeal and cleaning efficiency of detergents and personal care items [9]. Furthermore, its dispersing capabilities help to prevent the redeposition of soil onto surfaces during washing processes [10].

Application Scenarios

Alkyl Sulfonate SAS finds use in a wide array of applications, including laundry detergents, dishwashing liquids, hard surface cleaners, and personal care products like shampoos and body washes [11]. In industrial settings, it serves as an emulsifier and wetting agent in textile processing and oilfield applications [12]. Its effectiveness in various water hardness conditions and compatibility with other surfactants make it a versatile ingredient for formulators [13].

Packaging and Transportation

Alkyl Sulfonate SAS is typically packaged in multi-layer paper bags or woven polypropylene bags with polyethylene liners to prevent moisture absorption and ensure product integrity during storage and transport [14]. It is essential to store the product in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances, to maintain its stability and prevent degradation [15]. During transportation, precautions should be taken to avoid physical damage to the packaging and exposure to extreme temperatures or humidity [16].
