Sodium Laureth-4 Carboxylate

The Low-Foam Specialist: Superior Emulsification & Oil Solubilization

Sodium Laureth-4 Carboxylate is a mild, anionic surfactant with a lower ethylene oxide (EO) count than its counterpart (Laureth-6). This specific molecular structure gives it a slightly more "oil-loving" (lipophilic) character, making it exceptionally effective at dissolving oils and sunscreens while producing very low foam. It is the ideal choice for formulations where gentle cleansing and easy rinsing are prioritized over high foaming.

01. Advanced Makeup & Sunscreen Removal

Dissolves heavy formulas without irritation.

• Sunscreen Melter: Thanks to its superior oil-solubility, it excels in makeup removers and cleansers designed to break down waterproof sunscreens and long-wear cosmetics. It solubilizes oil-based UV filters gently, preventing the need for harsh scrubbing.

• Eye-Safe Mildness: Known for its extreme mildness, it is perfect for eye makeup removers. It cleanses the delicate eye area without stinging or irritation.

• Moisturizing Synergy: Often paired with Glycerin, it creates low-foam, non-stripping cleansers. Its low-foaming nature ensures a quick, residue-free rinse, leaving the skin feeling hydrated and soft rather than tight.

02. Industrial Metalworking & Coatings

Performance that protects the surface—and the worker.

• Metalworking Fluids: Functions as a premium emulsifier and lubricant. It forms a protective film on metal surfaces, significantly reducing friction during cutting and grinding.

  • HSE Benefit: Unlike harsh industrial additives, it is mild on the skin, reducing the risk of dermatitis for workers handling the fluids daily.

• Paints & Coatings: Acts as a highly effective dispersant in water-based coatings. It stabilizes pigment particles to prevent clumping, lowers viscosity, and improves the flow and leveling of the paint for a smoother finish.

03. Formulation Flexibility

The "Universal Compatibilizer."

• It exhibits outstanding compatibility with cationic, anionic, and non-ionic surfactants. Formulators use it to stabilize complex mixtures that might otherwise separate, making it a reliable "problem solver" in difficult recipes.
