Description

Sodium Ceteth-13 Carboxylate is a high-purity, anionic surfactant derived from ethoxylated cetyl alcohol. This compound is valued for its excellent emulsifying, cleansing, and foaming properties, particularly in formulations requiring mildness and stability. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking effective, skin-friendly surfactants. Its compatibility with a wide range of ingredients makes it a versatile choice for sophisticated emulsion systems.

Application

• Primary Surfactant in Facial Cleansers & Makeup Removers: Provides gentle yet effective cleansing without stripping the skin's natural oils.
• Emulsifier in Creams and Lotions: Stabilizes oil-in-water (O/W) emulsions in moisturizers, sunscreens, and body creams.
• Foam Booster in Shampoos and Body Washes: Enhances and stabilizes rich, creamy lather in rinse-off products.
• Base for Mild Baby Care Products: Ideal for formulations requiring high mildness and low irritation potential.
• Pharmaceutical Topical Preparations: Used in medicated creams and ointments as a non-irritating emulsifying agent.
• Industrial & Institutional (I&I) Cleaners: Serves as a key component in mild, high-foaming hard surface cleaners.

Quality Control

Our Sodium Ceteth-13 Carboxylate is manufactured under a cGMP-compliant quality management system. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and performance. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, pH, residual solvents, and heavy metals, supporting compliance for cosmetic and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
