Description
SWEP, also known as Sodium Lauryl Ether Sulfonate, is a surfactant derived from the sulfonation of lauryl alcohol ethoxylates. It is an anionic surfactant with excellent wetting, foaming, and emulsifying properties. Its hydrophilic and hydrophobic groups allow it to interact with various substances, making it a versatile ingredient in various applications.
Uses
Used in the Herbicide Industry:
SWEP is used as an active ingredient for enhancing the effectiveness of herbicides. Its surfactant properties help in the better dispersion and absorption of the herbicide on plant surfaces, leading to improved weed control and reduced chemical usage.
Used in the Cosmetics Industry:
SWEP is used as a foam booster and stabilizer in personal care products such as shampoos, shower gels, and bubble baths. Its excellent foaming and wetting properties contribute to a rich lather and improved cleaning performance.
Used in the Detergent Industry:
SWEP is used as a wetting agent and emulsifier in various cleaning products, including laundry detergents and dishwashing liquids. Its ability to reduce surface tension helps in the better penetration of cleaning agents into fabrics and dishes, resulting in more effective stain removal.
Used in the Textile Industry:
SWEP is used as a wetting agent and detergent in the textile industry, particularly during the scouring and bleaching processes. Its surfactant properties facilitate the removal of impurities, oils, and greases from fibers, leading to improved fabric quality and appearance.
Used in the Oil and Gas Industry:
SWEP is used as an emulsifier in the oil and gas industry to stabilize water-in-oil emulsions. Its ability to reduce interfacial tension between water and oil helps in the separation of water from crude oil, improving the efficiency of oil extraction and processing.
Used in the Agricultural Industry:
SWEP is used as a wetting agent and emulsifier in agrochemical formulations, such as pesticides and fertilizers. Its surfactant properties enhance the dispersion and absorption of these chemicals on plant surfaces, leading to improved nutrient uptake and pest control.
Chemical Properties:
SWEP is a crystalline solid that is insoluble in water and kerosene but soluble in acetone and dimethylformamide. These solubility properties make it suitable for use in various formulations and applications across different industries.
Hazard
Toxic by ingestion.
Check Digit Verification of cas no
The CAS Registry Mumber 1918-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1918-18:
(6*1)+(5*9)+(4*1)+(3*8)+(2*1)+(1*8)=89
89 % 10 = 9
So 1918-18-9 is a valid CAS Registry Number.

Process for the preparation of N,O-disubstituted urethanes suitable as a starting material for the preparation of isocyanates
-
, (2008/06/13)
A process for the preparation of N,O-disubstituted urethanes. Primary amines and alcohols are reacted with organic compounds having carbonyl groups at 120° to 350° C. Suitable carbonyl-containing compounds include N-unsubstituted urethanes. N-mono-substituted, N,N'-disubstituted ureas, or polyureas may be used in combination with the N-unsubstituted urethane. The product urethanes are particularly suitable for the preparation of isocyanates.
