Amphoteric Surfactant

Amphoteric surfactants are a unique class of surfactants that possess both hydrophilic and hydrophobic characteristics, allowing them to function effectively under various environmental conditions. Unlike anionic or cationic surfactants, amphoteric surfactants exhibit different properties depending on the pH of the environment. In neutral or alkaline conditions, they typically behave like anionic surfactants, whereas under acidic conditions, they act as cationic surfactants.

Main Types of Zwitterionic Surfactants

Amino Acid-Derived Zwitterionic Surfactants

This type of zwitterionic surfactant is made from natural amino acids, offering excellent biodegradability and low toxicity. They are widely used in cosmetics and skin care products.

Phosphate-Type Zwitterionic Surfactants

Phosphate-type zwitterionic surfactants are commonly used in industrial cleaning and agricultural applications. They possess strong emulsifying and detergency properties, making them particularly suitable for use in extreme environments.

Styrene Sulfonate-Type Zwitterionic Surfactants

This type of zwitterionic surfactant is mainly used in detergents and cleaning products. It effectively reduces foam while maintaining cleaning performance.

Applications of Amphoteric Surfactants

Cosmetics Industry

In the cosmetics industry, amphoteric surfactants are widely used in products such as cleansers, lotions, and facial masks. They offer mild cleansing properties that effectively remove impurities while maintaining the skin’s moisture balance and minimizing irritation. As a result, they are particularly suitable for individuals with sensitive skin.

Detergents and Cleaning Industry

In the cleaning industry, amphoteric surfactants are mainly used in the production of neutral or mild detergents. They provide efficient cleaning performance without damaging surfaces, making them ideal for use in household cleaning products as well as industrial cleaners.

Agricultural Industry

In agriculture, amphoteric surfactants are employed as stabilizers and emulsifiers for pesticides. They enhance the penetration and distribution of pesticides, thereby improving their efficacy. Additionally, they help reduce environmental pollution, aligning with eco-friendly standards.

Pharmaceutical Industry

In the pharmaceutical industry, amphoteric surfactants serve as drug carriers and sustained-release agents. They help improve the stability of medications and extend their therapeutic effects. Their use in drug formulations contributes to better absorption and increased bioavailability.

Food Industry

In the food industry, amphoteric surfactants function as emulsifiers and play an important role in food additives. They assist in emulsifying liquids and stabilizing foams, resulting in smoother textures and enhanced mouthfeel in food products.

What Success Stories Can We Share?

Discover how our products are applied in real-world scenarios through our case studies.

Case 1: Application of L-Thioproline-Derived Surfactant in Anti-Aging Skincare Products

Client Background:

The client is a company specializing in the research and development of skincare products, dedicated to creating gentle yet effective formulations, with a particular focus on anti-aging and skin repair. To enhance antioxidant performance and improve skin hydration, they were looking for a surfactant with good compatibility and mildness.

Purchased Amphoteric Surfactant:

L-Thioproline-derived amphoteric surfactant.

Application and Results:

This surfactant was mainly used in the formulation of high-performance antioxidant emulsions and facial masks. The L-Thioproline-derived surfactant exhibited excellent skin affinity, facilitating deeper penetration of active ingredients while being non-irritating to the skin. After incorporating the surfactant, the client observed significantly improved skin hydration and enhanced anti-aging effects. It proved particularly suitable for sensitive skin and greatly boosted the product's market competitiveness.

Case 2: Application of N-Methyl-DL-aspartic Acid-Derived Surfactant in Drug Sustained Release Systems

Client Background:

The client is a research institute focusing on biomedical R&D, with notable progress in the field of anticancer drug carriers. To improve the bioavailability and release profile of their drugs, they were searching for a surfactant that could stabilize drug components and enhance drug penetration.

Purchased Amphoteric Surfactant:

N-Methyl-DL-aspartic acid-derived amphoteric surfactant.

Application and Results:

This surfactant was used to develop a sustained-release drug delivery system. By adjusting the balance between hydrophilicity and hydrophobicity, it facilitated the stable release of drug compounds in the body. It was particularly suitable for anticancer drug formulations, helping to reduce side effects and enhance therapeutic efficacy. After application, the client noted significant improvements in drug stability, bioavailability, and controlled release performance, with fewer side effects and enhanced overall effectiveness.

Case 3: Application of Polylysine-Derived Surfactant in Food Preservation

Client Background:

The client is a food additive manufacturer specializing in natural preservatives and food safety technologies. To develop an efficient food preservative, they needed a natural, biodegradable surfactant to enhance preservation performance while ensuring food quality.

Purchased Amphoteric Surfactant:

Polylysine-derived amphoteric surfactant.

Application and Results:

This amphoteric surfactant was used as both an emulsifier and preservative in food packaging materials and direct food preservation treatments. It enhanced food stability and extended shelf life, helping products retain their original flavor and texture while reducing the need for chemical preservatives. After adoption, the client observed a significant extension of shelf life, particularly under high temperature and humidity conditions, with freshness and taste well preserved. The solution successfully met market demand for green and organic food options.
