Description

Hydroxyaluminum Distearate is a high-purity, organometallic compound widely recognized for its excellent gelling, thickening, and stabilizing properties. This versatile additive is crucial for formulating products with enhanced texture, consistency, and thermal stability. It serves as a key component for manufacturers in the cosmetics, pharmaceuticals, plastics, and coatings industries seeking reliable performance and batch-to-batch consistency.

Application

• Cosmetics & Personal Care: Acts as a gelling agent, thickener, and stabilizer in deodorants, antiperspirants, creams, and ointments to provide a smooth, non-greasy texture.
• Pharmaceuticals: Used as a rheology modifier and suspending agent in topical preparations, dermatological pastes, and controlled-release formulations.
• Plastics & Polymers: Functions as an acid scavenger, lubricant, and anti-blocking agent in PVC and polyolefin processing to improve clarity and processing stability.
• Paints & Coatings: Serves as a flatting agent and matting agent to control gloss and improve the application properties of industrial and decorative coatings.
• Greases & Lubricants: Employed as a thickening agent to produce consistent, high-temperature stable greases.
• Food Packaging: Used as a release agent and anti-caking agent in materials intended for food contact applications.
