We supply 1,2-Hexanediol cosmetic grade as INNO Proextend 1,2-Hexanediol, a cosmetic-grade multifunctional humectant, solvent and preservation-support ingredient.
Key Benefits of Proextend 1,2-Hexanediol
- Proextend 1,2-Hexanediol helps control yeast, mold and selected Gram-positive bacteria as part of a complete preservation system. It is a core material for streamlined multi-functional preservation concepts.
- The small polyol is an efficient humectant with strong water-binding ability. It adds moisturization to toner, serum, lotion, cream and mask formulas without introducing a separate heavy emollient.
- It also works as a solvent and sensory modifier. The material can lower viscosity and reduce tack, giving water-based products a cleaner, lighter skin feel.
- At the recorded 1% to 3% test range, closed-patch testing showed no erythema, edema or sensitization response. This supports its use in formulas developed for sensitive skin.
- The grade is readily biodegradable and works across water-based skin care and rinse-off products. INNO recommends confirming the final system through compatibility and microbial challenge testing.
Recommended applications
- Use Proextend 1,2-Hexanediol in toner, serum and water-based essence when the formula needs humectancy, solvent support and preservation assistance from one material.
- It fits lotion, cream and facial mask that require moisturization without adding a heavy emollient phase.
- In facial cleanser and cleansing mousse, the grade can soften tack and support the complete preservation system.
- It is also suitable for streamlined polyol preservation systems that will be confirmed through compatibility and microbial challenge testing.

Choosing between related INNO products
Choose 1,2-Hexanediol when the formula needs humectancy, solvency and preservation support. Ethylhexylglycerin provides more emollient character, while Phenoxyethanol is the primary preservative.
Frequently asked questions
Is 1,2-Hexanediol a complete preservative on its own?
Use it as a multifunctional part of the preservation system, not as an automatic standalone answer. It contributes antimicrobial support, humectancy and solvency, while the complete blend must cover the microbial risks of the formula and package.
Viscosity fell after 1,2-Hexanediol was added. How should the cause be isolated?
Compare early and late addition in two otherwise identical batches, then record viscosity after the same equilibration time. Rebuild the thickener setting in the complete formula instead of correcting a water-only premix.
What information is needed to design a meaningful challenge test?
Define the product format, water activity, pH, packaging, consumer-use pattern and the rest of the preservation system. Test the market-ready formula in its final pack, because the raw ingredient result does not establish finished-product protection.
When should packaging change the preservation plan for a 1,2-Hexanediol system?
A wide-mouth jar, repeated finger contact or a wet-wipe pack creates a different contamination route from a closed pump. Set the challenge and in-use test around the intended package instead of qualifying the bulk formula alone.
Why work with INNO?
INNO combines raw-material supply with preservation-system testing. We can review the complete formula, arrange samples and support challenge-test planning.
