DOE-120 Series Thickeners: Solving the Thickening Challenges of Amino Acid Surfactant Systems

A Practical Solution to Formulation Challenges

Compared with traditional sulfate-based surfactants, amino acid surfactants have gained widespread recognition in the market due to their excellent mildness, low irritation, and good biodegradability. 

With the growing demand in the personal care industry for gentle cleansing products and enhanced user experiences, amino acid surfactants are being increasingly used in various cleansing formulations. 

However, formulators often face a common challenge: achieving the desired thickening effect in amino acid surfactant systems. The DOE-120 Series non-ionic associative thickeners provide an effective solution by helping mild cleansing systems reach target viscosity while preserving the formulations’original benefits.B-Ai’s DOE-120 Series thickeners are specially designed for amino acid surfactant systems and are suitable for transparent amino acid cleansing products under various manufacturing conditions. Featuring a structure built upon corn derived glucose derivatives, these ingredients fit well with the current market trend toward gentle and bio based personal care ingredients.

Why Is Thickening Amino Acid Surfactant Systems More Challenging?

Traditional sulfate-based surfactant systems can usually achieve good viscosity through conventional salt-thickening methods. However, amino acid surfactants have unique molecular structures and micellar interaction behavior, making traditional salt thickening methods less effective at achieving the desired viscosity.

The goal is not simply to increase viscosity. A well-balanced cleansing product must also maintain transparency, stability, mildness, and a pleasant texture. A suitable rheology modifier can balance these requirements by providing an alternative thickening approach based on non-ionic associative thickening technology, offering a more effective solution for mild cleansing formulations.

B-Ai Provides Flexible and Versatile Thickening Solutions

B-Ai’s amino acid surfactant thickener series is available in both solid and liquid formats, allowing finished product manufacturers to select the most suitable option according to their raw material handling preferences, production equipment, and processing conditions.

The series is compatible with both hot-processing and cold-processing methods, suited to different manufacturing processes.

PEG-120 Methyl Glucose Dioleate is the core product of this series. When used at an appropriate dosage, it can help improve the rheological performance of amino acid surfactant systems.

PEG-120 Methyl Glucose Dioleate & Water (liquid) is supplied in liquid form, providing convenience in raw material handling and production addition processes.

PEG-120 Methyl Glucose Dioleate & Propylene Glycol & Water (liquid) offers another liquid option, bringing greater flexibility for different formulations and manufacturing processes.

PEG-120 Methyl Glucose Trioleate further expands the thickening options available for amino acid surfactant systems, meeting diverse product characteristics and application requirements.

Supporting Transparent and Mild Cleansing Products

One of the key advantages of this series is its excellent compatibility with transparent amino acid cleansing products. For personal care products focusing on gentle skin care, mild cleansing, and natural ingredient concepts, both viscosity and appearance are critical factors influencing consumer experience.

B-Ai’s thickening solutions are ideal for use in the following products:

1. Shower Gel 
2. Facial Cleanser 
3. Hand Wash 
4. Shampoo 
5. Baby Care Products 

Consistent Quality Comes from Strict Production Management

For B-Ai, product quality and batch-to-batch performance consistency are high priorities. Functional ingredients used in personal care formulations require stable performance between batches. This is especially important for rheology-modifying ingredients, as even small variations may affect the viscosity, appearance, and overall texture of the final product.

B-Ai implements rigorous quality oversight across raw material screening, supply chain QA and finished goods verification. Through standardized quality management systems, B-Ai ensures stable product performance and provides customers with reliable application assurance.

For rheology-modifying ingredients, such consistency is particularly important because subtle performance differences can directly influence the final performance of cleansing products.

More Than Products, We Focus on Practical Application Support

Selecting the right thickening solution requires consideration of multiple practical factors, including the surfactant system, processing method, temperature conditions, and desired final texture. B-Ai understands that each customer has unique manufacturing environments and application requirements.

Therefore, B-Ai focuses on technical communication and application support, offering tailored guidance based on customers’ actual production conditions. This helps customers better understand product characteristics and adopt the most compatible solutions for their production workflows.

This service approach reflects B-Ai’s brand philosophy: we deliver not only premium functional ingredients, but also dependable technical support and long term collaborative value.

Helping Mild Cleansing Products Achieve Better Balance

As consumers continue to seek gentle and comfortable cleansing products, amino acid surfactants remain a mainstream option in the personal care market. The difficulty of thickening amino acid systems should not become a barrier to product development and commercialization.

Featuring non-ionic associative thickening technology, corn-derived ingredient structures, diversified solid and liquid grades, and compatibility with both hot and cold processing methods, B-Ai provides practical and effective solutions for optimizing the rheological performance of amino acid surfactant systems.

Applicable for shower gels, facial cleansers, hand washes, shampoos, and baby care products, suitable rheology modifiers can help formulators achieve a better balance between mildness, transparency, sensory texture, and manufacturing efficiency.
