Description

Sodium Peg-7 Olive Oil Carboxylate is a high-performance, plant-derived anionic surfactant and emulsifier. This specialty chemical is valued for its excellent cleansing, foaming, and skin-conditioning properties, derived from the ethoxylation and carboxylation of natural olive oil. It is primarily sought after by formulators in the personal care, cosmetics, and high-end cleaning industries who require mild, biodegradable, and naturally-derived ingredients. Its unique structure provides a favorable balance between effective performance and enhanced sensory profile in finished products.

Application

• Personal Cleansers: A key surfactant in mild facial cleansers, shower gels, and liquid soaps, where it contributes to a rich, stable lather and a soft after-feel.
• Cosmetic Emulsions: Functions as a primary or co-emulsifier in skin creams, lotions, and sun care products, stabilizing oil-in-water formulations.
• Hair Care Systems: Used in shampoos and conditioners for its gentle cleansing and conditioning effects, improving hair manageability and shine.
• Baby Care Products: Ideal for formulations requiring extra mildness, such as baby shampoos, washes, and wipes.
• Premium Household Cleaners: Incorporated into biodegradable and eco-friendly dish liquids, all-purpose cleaners, and hand soaps for effective grease removal with a skin-friendly profile.
• Pharmaceutical Topicals: Serves as an emulsifying agent in medicated creams, ointments, and dermatological preparations.

Quality Control

Our Sodium Peg-7 Olive Oil Carboxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, moisture content, and heavy metals are available upon request. We adhere to relevant cosmetic ingredient standards and can support compliance requirements for global markets.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong acids and organic solvents.
