Description

Siloxanes And Silicones, 3-3-(Carboxymethyl)Dimethylammonio-2-Hydroxypropoxypropyl Me, Di-Me, Hydroxides, Inner Salts is a specialized organomodified silicone surfactant, specifically a betaine-functional siloxane. This unique structure combines the excellent surface activity and spreading properties of silicone with the mildness, substantivity, and compatibility of a betaine amphoteric surfactant. It is engineered for formulators who require advanced performance in demanding personal care and industrial applications where stability, mildness, and multifunctionality are critical.

Application

• High-performance conditioning agent in shampoos, conditioners, and hair treatments, providing excellent detangling, softness, and shine with reduced irritation.
• Primary or co-surfactant in mild cleansing systems for facial washes, body washes, and baby care products, enhancing foam quality and skin feel.
• Emulsifier and stabilizer in silicone-in-water and oil-in-water emulsions for creams, lotions, and sun care products.
• Antistatic and softening agent in textile and fabric care formulations.
• Wetting and leveling agent in coatings, inks, and agrochemical formulations to improve substrate coverage and film uniformity.
• Lubricity and surface modification additive in industrial process fluids and release agents.

Quality Control

Our production of this advanced silicone surfactant adheres to strict quality management systems (ISO 9001). Every batch is characterized using advanced analytical techniques to ensure consistent chemical structure, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, pH, and other critical parameters is provided with each shipment to guarantee it meets your formulation specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
