    Product Description

    Dexpanthenol CAS 81-13-0 is the biologically active D-enantiomer of panthenol, also known as provitamin B5, with EC 201-327-3 and molecular formula C9H19NO4.

    Synonyms: D-Panthenol; D-Pantothenyl Alcohol; Provitamin B5.

    CAS: 81-13-0.

    Molecular formula: C9H19NO4.

    It has a molecular weight of about 205.25 g/mol.

    It is usually supplied as a colorless to slightly yellowish clear, viscous liquid.

    It is freely soluble in water and soluble in alcohol and propylene glycol, with a density commonly reported around 1.20 g/mL at 20 C.

    It is positioned as a formulation ingredient rather than a general chemical intermediate.

    It is used in skin care for moisturizing, humectant, emollient, and conditioning benefits.

    It is used in hair care formulations.

    It is used in topical pharmaceutical preparations where panthenol functionality is specified.

    It is the active D-form, unlike DL-panthenol, which is a 50:50 racemic mixture of D- and L-panthenol.

    Confirm the required grade, purity, optical rotation, appearance, water content, and related specifications for the chosen grade.

    Store in tightly closed original containers in a cool, dry, well-ventilated area, away from excessive heat and direct sunlight.

    Keep containers sealed after opening and protect the material from contamination during handling, storage, and transport.

    Confirm packaging suitable for the liquid form and order quantity, and follow the current SDS.

    Confirm grade, packaging, and specification as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Dexpanthenol CAS 81-13-0?

      A: Dexpanthenol is the biologically active D-enantiomer of panthenol, also known as D-panthenol or provitamin B5. It has the molecular formula C9H19NO4 and a molecular weight of about 205.25 g/mol.
    • Q:

      What is the difference between Dexpanthenol and DL-Panthenol?

      A: Dexpanthenol is the active D-form, while DL-panthenol is a 50:50 racemic mixture of D- and L-panthenol. The L-form is not efficiently converted to vitamin B5, so the D-form provides the full biological activity and is the preferred specification for functional cosmetic or topical use.
    • Q:

      What are the main applications of Dexpanthenol?

      A: It is used in skin care, hair care, and topical formulations for moisturizing, humectant, emollient, and conditioning benefits. It is also used in pharmaceutical-related preparations where panthenol functionality is specified.
    • Q:

      What are the typical physical and solubility properties of Dexpanthenol?

      A: Dexpanthenol is usually a colorless to slightly yellowish clear, viscous liquid. It is freely soluble in water and soluble in alcohol and propylene glycol, with a density commonly reported around 1.20 g/mL at 20 deg C.
    • Q:

      How should Dexpanthenol be stored and handled?

      A: Store it in tightly closed original containers in a cool, dry, well-ventilated area away from excessive heat and direct sunlight. Keep containers sealed after opening and protect the material from contamination during handling, storage, and transport.
