Core Characteristics and Application Scenarios

This product is specially designed for all categories of daily chemical products, with core application scenarios as follows:

• Toothpaste Products: Suitable for various formulas including whitening toothpaste, anti-caries toothpaste and sensitive toothpaste. It can be used as a mild abrasive, thickener and suspension stabilizer, providing efficient cleaning and decontamination ability without damaging tooth enamel, while improving paste stability and smoothness without gritty or foreign body sensation.

• Powder Cosmetics: Suitable for makeup products such as loose powder, pressed powder, eye shadow, blush and setting powder, as well as body care powders such as talcum powder and antiperspirant powder. It plays excellent flow aid, anti-caking and anti-agglomeration roles, while adjusting powder smoothness, improving makeup adherence and spreadability, and solving production pain points such as uneven powder feeding and poor filling accuracy.

• Personal Care and Skincare Products: Suitable for products such as shampoos, body washes, conditioners, face creams and lotions. It can be used as a suspension stabilizer, thickener and skin feel modifier, effectively suspending insoluble components such as silicone oils, active particles and anti-dandruff agents, improving system stability, and enhancing product application smoothness without stickiness.

• Cream and Paste Makeup Products: Suitable for products such as liquid foundations, concealers, lipsticks and lip glosses. It plays roles in pigment dispersion, system thickening and skin feel adjustment, improving pigment dispersion uniformity, preventing sedimentation and layering, and optimizing product application spreadability.

Note: The actual application effect of the product varies due to customers' formula systems and production processes. The final result shall be subject to customers' actual test results.
