Surfactant Categories
TABLE. ACTIVE CLASS
Anionic surfactants mainly include four major types: carboxylates, sulfonates, sulfate esters, and phosphate esters.
For example, amino acid–based surfactants belong to this category. These surfactants contain hydrophilic amide groups, making them mild and low-irritation.
However, due to the relatively large hydrophilic groups, thickening can be challenging. By substituting specific functional groups and adjusting the carbon chain length (either increasing or reducing it), the performance of the surfactants can be optimized, enabling the development of customized, proprietary raw materials.
Plant Extracts
PLANT EXTRACTS
We source plant-derived extracts with targeted functional benefits, ensuring both safety and high efficacy.
For example, selected traditional herbal ingredients are blended, pulverized, and sieved, followed by extraction with appropriate solvents. The extract is then heated under reflux, decolorized, and filtered. The resulting filtrate is concentrated under reduced pressure to obtain a paste-like extract.
The extracted herbal complex demonstrates strong ultraviolet absorption, along with excellent free radical scavenging activity and tyrosinase inhibition.
It is a safe and highly effective natural sunscreen agent, suitable for use in sun care and sunscreen cosmetic formulations.
Powders
POWDERS
In physical sunscreen agents, titanium dioxide (TiO₂) offers several advantages, including high production yield, high whiteness, strong covering power, cost efficiency, and excellent stability.
However, unmodified nano-sized titanium dioxide particles exhibit drawbacks such as high hydrophilicity, high oil absorption, easy agglomeration, and strong photocatalytic activity, which limit their application in cosmetic formulations to some extent.
Through inorganic/organic composite surface modification, high-performance modified titanium dioxide can be obtained. When incorporated into cosmetic products, the modified titanium dioxide significantly enhances UV protection performance and overall whiteness of the formulation.
