What does PEG  Lanette® N (Sodium Cetearyl Sulfate & Cetearyl Alcohol) do in a formulation?

• Self-Emulsifying O/W Base: Primary function. Forms stable oil-in-water emulsions without requiring additional emulsifiers. The Sodium Cetearyl Sulfate provides the emulsifying power while Cetearyl Alcohol provides consistency.
• Consistency Factor: The Cetearyl Alcohol component gives body and structure to emulsions, providing the desired thickness and richness to creams and lotions.
• Emulsion Stabilizer: Stabilizes emulsions by forming a protective interfacial film around oil droplets, preventing coalescence and separation over time.
• Viscosity Modifier: Allows formulators to adjust the final viscosity of products by varying the concentration used.
• Skin Feel Enhancer: Absorbs into the skin without leaving a greasy feel, providing a smooth, non-tacky after-feel.
• Opacifier: Contributes to the opaque, rich, creamy appearance of emulsions .

Safety Profile:

· Hazard Classification: Considered safe for use in cosmetics and personal care. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Sodium Cetearyl Sulfate and related alkyl sulfates are safe as used in cosmetics .

· Acute Oral Toxicity: Studies on Sodium Cetearyl Sulfate revealed no toxicity .

· Skin Irritation: Undiluted Sodium Cetearyl Sulfate may cause mild irritation, but in aqueous form (20%) it does not irritate skin . It causes less skin irritation than Sodium Lauryl Sulfate (SLS) .
