Description of Triethanolamine Lauryl Sulfate - What you need to know

Surface activity

DSTS has excellent surface activity, can significantly reduce the surface tension of water at a low concentration, and has good wetting, emulsification and decontamination properties. Because of these properties, DSTS is widely used in water treatment, metal processing, cosmetics and personal care products.

Foaming

The foamability of DSTS depends on its molecular structure and concentration. At low concentrations, the foaming ability of DSTS is weak. In high concentrations, its foaming ability is stronger. This characteristic makes DSTS have a certain application in the fields of foam fire extinguishers, foam cleaning agents and foam blowing agents.

Thickening

DSTS has good thickening properties and can significantly increase the viscosity of the solution at a lower concentration. This property gives DSTS a certain application value in preparing emulsions, suspensions and pastes.

Stability

DSTS has good chemical and thermal stability and can maintain stability under various pH values and temperature conditions. In addition, DSTS also has certain oxidation and corrosion resistance, which is conducive to its application in more demanding environments.

Compatibility

DSTS is compatible with other surfactants, salts, oils, etc., and can coordinate with other components in the formulation to achieve ideal performance. This provides convenience for its wide application in various cleaning agents, cosmetics, pesticides and other fields.

Biodegradability

DSTS has certain biodegradability and can be broken down into harmless substances by microorganisms in the natural environment. This helps to reduce environmental pollution and ecological damage, in line with the requirements of green environmental protection.

 Technical Parameters of Triethanolamine Lauryl Sulfate

Applications of Triethanolamine Lauryl Sulfate：

Home and personal care products: Triethanolamine dodecyl sulfate is an important ingredient in many personal care products such as shampoos, body washes, facial cleansers and toothpaste. 

Industrial cleaning: In industrial production, various equipment and tools must be cleaned regularly to remove oil, rust and residue. Triethanolamine dodecyl sulfate has a strong cleaning ability, which can effectively remove these stubborn stains and improve the operating efficiency of equipment and product quality.

Textile industry: In the textile industry, triethanolamine dodecyl sulfate is mainly used as a softening and antistantistatic. It can give textiles a soft feel and anti-artist aesthetics, improving textiles' quality and comfort.

Agriculture: In the agricultural sector, triethanolamine dodecyl sulfate can be used as an emulsifier for pesticides, helping to disperse pesticides evenly in water for easy spray application. In addition, it can also be used as an additive to fertilizers and pesticides to improve the absorption of nutrients and the effect of disease and pest control.

Pharmaceutical industry: In the pharmaceutical industry, triethanolamine dodecyl sulfate can be used as a drug carrier and release agent to help drugs penetrate the skin or target organs better, improve the efficacy of drugs and reduce side effects.

Cosmetics industry: In cosmetics, triethanolamine dodecyl sulfate is mainly used to manufacture soap, body wash, shampoo and other products, it can help the product form a rich foam, and has excellent washing and cleaning capabilities. At the same time, it can also be used as an emollient and moisturizer in cosmetics to help moisturize the skin and improve its elasticity.

Production Method of Triethanolamine Lauryl Sulfate：

Direct esterification

Direct esterification is a commonly used method to prepare triethanolamine dodecyl sulfate. The method directly reacts dodecyl sulfuric acid with triethanolamine to produce the target product. The reaction equation is as follows:

C12H25SO3H + 3(C2H5O)NH2 → C12H27SO3NHCH2CH2NHCH2CH2OH

In the direct esterification process, sulfuric acid or sulfur trioxide is usually used as a catalyst to promote the reaction. The advantage of this method is that the reaction step is simple, but the reaction conditions, such as temperature, pressure and material ratio.

Transesterification method

Transesterification is another method for preparing triethanolamine dodecyl sulfate. The method is to react long-chain fatty acids with ethanolamine to produce the corresponding ester and then exchange the generated ester with triethanolamine to produce the target product. The reaction equation is as follows:

C12H25CO2CH3 + 3(C2H5O)NH2 → C12H27CO2NHCH2CH2NHCH2CH2OH

In the transesterification process, acidic catalysts such as sulfuric acid or hydrochloric acid are usually used to facilitate the transesterification reaction. The advantages of this method are that the raw material is easy to obtain and the price is low, but multi-step reaction and separation operations are required, and more by-products are produced.

The mixed alcohol amine method

The mixed alkylamine method is an improved method for preparing triethanolamine dodecyl sulfate. Mix long-chain alkyl alcohols and triethanolamine and then esterify with sulfuric acid to produce the target product. The reaction equation is as follows:

C12H25OH + 3(C2H5O)NH2 + H2SO4 → C12H27SO3NHCH2CH2NHCH2CH2OH

The advantage of this method is that it avoids using toxic and harmful organic solvents and reduces environmental pollution.
