What is Pentylene Glycol?

Pentylene Glycol (INCI: Pentylene Glycol; CAS 5343-92-0), chemically 1,2-pentanediol, is a clear, colorless, nearly odorless liquid vicinal diol valued for its exceptionally light, elegant skin feel. It is a multifunctional moisturizing glycol that attracts and binds water while acting as a preservation booster: like other 1,2-diols, it interferes with microbial membranes and enhances the performance of conventional preservatives, often allowing lower overall preservative levels. Beyond hydration and preservation, it serves as a versatile solvent and carrier for actives and botanical extracts, improves the sensory profile of gels and emulsions, and helps keep formulations clear and stable. Gentle and well tolerated, it is widely used in premium skin care, serums, masks, wipes and sensitive-skin products.

Key Benefits

• Light-touch moisturizing: delivers soft hydration without weight, greasiness or tack.
• Preservation boost: supports and enhances traditional preservative systems at low use levels.
• Better sensory profile: refines the texture of gels, serums and emulsions for an elegant, cushiony feel.
• Versatile humectant and solvent: carries actives and extracts and helps keep water-based systems clear.
• Broad formulation compatibility: stable over a wide pH range and compatible with most cosmetic ingredients.
• Mild and well tolerated: suitable for sensitive skin, baby care and eye-area products.
• Easy to use: a free-flowing liquid convenient in both hot and cold processing.

FAQ

Q1: What is the difference between pentylene glycol and propylene glycol? A1: Pentylene glycol has a longer five-carbon chain, giving a lighter, more elegant skin feel and useful preservation-boosting properties.

Q2: Is it a preservative? A2: It is a preservative booster and humectant; it is normally combined with a primary preservative and validated by challenge testing.

Q3: Is it suitable for sensitive or blemish-prone skin? A3: Yes — it is mild and valued in high-end sensitive and blemish-prone formulations.
