Description

What is Pentaerythrityl Tetraethylhexanoate?

YLPTO (INCI: Pentaerythrityl Tetraethylhexanoate; CAS 7299-99-2) is a premium synthetic tetraester formed by the esterification of pentaerythritol with four molecules of 2-ethylhexanoic acid. It is a clear, low-viscosity liquid. Thanks to its highly branched, symmetric molecular structure, the ester combines a light, dry skin feel with excellent oxidative and thermal stability — properties rarely found together in natural oils. INGRELINK supplies cosmetic-grade Pentaerythrityl Tetraethylhexanoate at a minimum purity of 98.5%, making it a reliable building block for formulators developing high-performance skincare, color cosmetics, sun care and hair care products.

Key Benefits

• Lightweight, non-greasy skin feel: delivers a smooth, silky after-feel without the heavy, oily residue associated with mineral oil and many natural triglycerides.
• Excellent spreadability and glide: enables effortless, even application and reduces friction during rub-in, creating an elegant sensory experience.
• Breathable protective film: forms a light occlusive layer on the skin that helps reduce transepidermal water loss while allowing normal skin respiration.
• Outstanding stability: the fully esterified structure resists oxidation and rancidity, supporting a long shelf life and compatibility with sensitive formulations.
• Effective pigment wetting and dispersion: wets inorganic pigments and treated powders, improving color uniformity and stability in makeup.
• Versatile compatibility: miscible with most cosmetic oils, esters and silicones, and compatible with a wide range of emulsifier systems.
• High purity, low odor: suitable for fragrance-sensitive and premium formulations.

• Sun care and antiperspirants: sunscreen lotions and deodorant/antiperspirant sticks, valued for its stability and smooth application.
• Cleansing products: cleansing oils, cleansing balms and makeup removers, helping dissolve makeup and sunscreen while rinsing off comfortably.
