Description

What is Neopentyl Glycol Diethylhexanoate?

YLNGD (INCI: Neopentyl Glycol Diethylhexanoate; CAS 28510-23-8) is a premium dual-branched synthetic diester formed by the esterification of neopentyl glycol with two molecules of 2-ethylhexanoic acid. It is a clear, colorless, low-viscosity liquid with a molecular formula of C21H40O4. The combination of the compact neopentyl glycol backbone and two branched fatty-acid chains gives the ester its characteristic ultra-light, dry skin feel and a low cloud point, while the fully esterified structure provides high oxidative stability.

Key Benefits

• Ultra-light, non-greasy dry feel: absorbs quickly and leaves a smooth, silky after-feel without the heaviness of mineral oil or natural triglycerides.
• Excellent low-temperature performance: a low cloud point keeps the ester clear and pourable in cold conditions and prevents crystallization in finished products.
• Outstanding spreadability: the dual-branched structure delivers effortless spreading and a long, elegant glide during application.
• Mineral and silicone oil alternative: recreates the light, fast-spreading feel of volatile silicones such as cyclomethicone in a non-volatile ester, without the skin-hardening concerns of long-term silicone use.
• Supports active delivery: medium polarity and good solvency carry lipophilic actives and support their skin absorption.
• Broad formulation compatibility: miscible with most cosmetic oils and compatible with anionic, nonionic and cationic surfactant systems.
• High oxidative stability, low odor: resists rancidity and suits fragrance-sensitive and premium formulations.

FAQ

Q1: Is Neopentyl Glycol Diethylhexanoate safe for topical use?

A1: Yes. It is a well-established cosmetic ingredient considered safe for leave-on and rinse-off products within typical use levels. Review the SDS and your target markets’ regulations.

Q2: Can it really replace silicone oils?

A2: It reproduces the light, fast-spreading, dry feel of volatile silicones such as cyclomethicone in a non-volatile ester, making it ideal for silicone-free claims.

Q3: Why does low-temperature performance matter?

A3: A low cloud point prevents cloudiness, crystallization or texture changes during cold storage and winter distribution, keeping anhydrous products smooth.

Q4: Can I request samples and documentation before ordering?

A4: Yes. Contact us for samples, COA, SDS and formulation guidance; our technical team supports you from trial to scale-up.
