Product Benefits

• Powerful Moisturizing & Emollient Effect

Powerful Moisturizing & Emollient Effect Working as premium humectant raw material, 1,2-Pentanediol, also named Pentylene Glycol, efficiently raises epidermal water content, locks skin moisture and prevents skin dryness & tightness, specially tailored for dry & sensitive skincare formulas. When formulated into cream, lotion, facial serum, shampoo and hair conditioner, this versatile glycol shields skin from harsh ambient dry damage to keep skin soft hydrated, also softens hair cuticle for silky hair texture. Pentylene Glycol has become mainstream raw material for OEM moisturizing personal care finished products thanks to its reliable moisturizing performance.

• High-efficiency Cosmetic Solvent

High-efficiency Cosmetic Solvent

Boasting excellent universal solvent capacity, 1,2-Pentanediol is freely soluble in water and most organic solvents and able to dissolve hard-soluble cosmetic functional raw materials. Widely used in facial cleanser, makeup remover, nail polish remover formulations, Pentylene Glycol improves raw material dispersion, optimizes product texture and enhances finished cosmetic stability, which makes it a necessary solvent ingredient in daily cosmetics development.

• Mild Antimicrobial & Preservative Booster

Mild Antimicrobial & Preservative Booster With inherent natural antibacterial attribute, Pentylene Glycol (1,2-Pentanediol) acts as popular auxiliary preservative with low irritation. It suppresses harmful bacteria & fungi proliferation and effectively cuts down extra synthetic preservative dosage in cosmetic formulas. Adding 1,2-Pentanediol into lotions, moisturizers and all kinds of personal care goods stabilizes product shelf life and minimizes microbe-caused skin irritation risk, an ideal ingredient for clean-beauty low-preservation cosmetic development.

• Acid-Alkali Stable Multi-industry Raw Material

Acid-Alkali Stable Multi-industry Raw Material

Featured with low volatility and stable property under acidic & alkaline surroundings, 1,2-Pentanediol perfectly fits cosmetic, pharmaceutical, food & fragrance four major industries. In pharma industry, Pentylene Glycol works as antioxidant & solvent for oral care preparations; in food & flavor field, 1,2-Pentanediol serves as flavor enhancer and perfume carrier to prolong fragrance retention, widely applied for diversified industrial formula production.

Product Application

You can use the 1,2-Pentanediol in the following scenarios:

For Cosmetic & Personal Care Products

Frequently Asked Questions

Q1: What is the typical recommended addition dosage of 1,2-Pentanediol (Pentylene Glycol) in cosmetic formulas?

A1: The regular addition amount of 1,2-Pentanediol in daily skincare formulas ranges from 2% to 8%. When used as primary auxiliary preservative to cut chemical preservative addition, the dosage can be adjusted up to 5%-10% according to your finished product's formulation system.

Q2: What advantages does 1,2-Pentanediol have over other conventional humectant glycol raw materials?

A2: Different from common small-molecule polyols, 1,2-Pentanediol combines moisturizing, solubilizing and mild antibacterial functions in one single ingredient. It features stable performance under acidic and alkaline environments with low irritation, helping brands develop clean-label formulas with reduced synthetic preservatives.

Q3: Which finished product categories is 1,2-Pentanediol applicable for?

A3: 1,2-Pentanediol is widely applicable to OEM production of facial creams, lotions, serums, shampoos, oral care supplies as well as pharmaceutical preparations and food flavoring raw materials, with excellent compatibility for diversified formulation systems across multiple industries.

Q4: Is 1,2-Pentanediol easy to dissolve and blend into different formulas?

A4: 1,2-Pentanediol is fully miscible with water and most conventional organic solvents at normal room temperature, no agglomeration or stratification occurs during feeding. It can be uniformly mixed into aqueous, oil-water emulsified and solvent-type formulas efficiently.

Q5: Can 1,2-Pentanediol replace traditional chemical preservatives entirely in cosmetics?

A5: It cannot fully substitute high-efficiency chemical preservatives alone, yet adding proper proportion of 1,2-Pentanediol can greatly decrease the usage of parabens and other synthetic preservatives, effectively lowering skin irritation risk and meeting clean beauty formulation demands.
