Why is 1,2-Hexanediol described as a preservative booster?

It is not a broad-spectrum preservative on its own, but it can support the antimicrobial performance of a complete preservation system. This multifunctional behavior allows formulators to improve product protection while also using the ingredient for solvent, moisture-binding, and texture benefits.

What cosmetic applications is 1,2-Hexanediol used in?

It is commonly evaluated in skin care products, hair care products, cleansing formulas, lotions, creams, serums, masks, and specialty personal care systems. It can help dissolve or disperse selected ingredients, support moisture retention, and contribute to a smooth formula texture.

What is the difference between 1,2-Hexanediol and 1,6-Hexanediol?

1,2-Hexanediol has hydroxyl groups on adjacent carbon atoms and is mainly used in cosmetic and formulation applications. 1,6-Hexanediol has hydroxyl groups at the ends of the chain and is used in different industrial, coating, and polymer applications. The two materials should not be substituted without confirming the correct CAS number and grade.

Which specification values should buyers confirm for cosmetic-grade 1,2-Hexanediol?

Buyers should compare assay or purity, appearance, color, odor, water content, acidity or pH-related indicators, heavy metals, and microbial limits where applicable. The chosen grade should also be tested for solubility and stability in the target formulation.

Main Applications

1,2-Hexanediol CAS 6920-22-5 is a multifunctional diol used in cosmetic, personal care, and fine chemical formulations. It is valued by formulators for its role as a humectant, solvent, emollient-support ingredient, and preservative booster in water-based and emulsion systems.

In B2B sourcing, 1,2-Hexanediol is commonly considered for skin care products, hair care products, cleansing formulations, lotions, creams, serums, masks, and specialty personal care systems. It may also be used in fine chemical and industrial formulations where a low-odor diol solvent or formulation aid is required.

Application Area	Buyer-Relevant Use Direction
Skin Care Formulations	Used in creams, lotions, serums, gels, and masks to support moisture retention, texture, and formula stability.
Personal Care and Cleansing Products	Suitable for selected cleansing, bath, and rinse-off products where a multifunctional solvent and humectant is required.
Preservative-Boosting Systems	Often used as a preservative-support ingredient to improve the performance of cosmetic preservation systems.
Solvent and Co-Solvent Applications	Helps dissolve or disperse selected ingredients in cosmetic and specialty formulation systems.
Fine Chemical Formulations	May be evaluated as a diol solvent or formulation aid in selected fine chemical and industrial applications.

Product Specifications

1,2-Hexanediol is generally supplied as a clear to slightly yellow liquid, depending on grade and supplier specification. For cosmetic and personal care use, buyers usually review appearance, assay, water content, color, odor, acidity or pH-related indicators, heavy metals, microbial limits where applicable, and compatibility with the target formulation.

Exact specification values should be confirmed with the current TDS, COA, or agreed supply standard. If your formulation requires a specific purity, odor profile, color limit, water content, or cosmetic-grade documentation, please provide the target requirements during inquiry.

Packaging and Supply

1,2-Hexanediol CAS 6920-22-5 can be supplied in sealed industrial packaging suitable for cosmetic raw materials, personal care ingredients, and fine chemical use. Packaging may include pails, drums, IBC drums, or other suitable export packaging according to grade, quantity, and shipment requirements.

For quotation and supply confirmation, buyers are encouraged to provide the intended application, required grade, target specification, order quantity, packaging preference, destination country or port, and document requirements. This helps confirm whether the available grade is suitable for skin care, cleansing products, preservative-boosting systems, or other formulation applications.

Storage and Handling

Store 1,2-Hexanediol in a cool, dry, and well-ventilated area. Keep containers tightly closed when not in use. Protect the product from contamination, direct sunlight, excessive heat, and incompatible substances.

Use suitable protective equipment during handling and avoid direct contact with eyes and skin. For cosmetic formulation use, buyers should review the latest SDS and technical data before testing, storage, transportation, or production-scale use.
