D-Panthenol Liquid 75% Provitamin B5 Solution is a concentrated form of provitamin B5, also known as D-panthenol, supplied at a 75% concentration in a 1 oz (30 mL) bottle by Talsen Chemicals. This solution is intended for use in skin, hair, and cosmetic formulations as a moisturizing ingredient. D-panthenol is a stable, alcohol-soluble derivative of pantothenic acid, which converts to vitamin B5 upon application. In formulations, it functions as a humectant and emollient, helping to attract and retain moisture in the outer layers of the skin and hair cuticle.

This ingredient is commonly included in leave-on and rinse-off products such as creams, lotions, serums, shampoos, conditioners, and styling aids. When incorporated into hair care formulations, it can contribute to improved manageability, reduced breakage, and enhanced shine by forming a flexible film that smooths the hair shaft. In skin care, it supports hydration and may assist in soothing minor irritation, making it suitable for inclusion in products designed for dry or sensitive skin types. The liquid consistency allows for easy blending into cold-process or heated formulations at recommended usage levels typically between 0.5% and 5% of the total formula.

Talsen Chemicals provides this ingredient as a raw material for cosmetic manufacturers, DIY formulators, and small-batch producers. The 75% concentration is higher than many standard panthenol solutions, offering flexibility in dosage and reducing the volume needed to achieve desired effects. The product is not intended for direct consumer application; it is a formulation ingredient that should be diluted or combined into finished products. Storage in a cool, dry place away from direct sunlight helps maintain stability. This solution is clear to slightly hazy, with a mild characteristic odor, and is soluble in water and alcohol. Suitable for a range of pH levels, it remains stable in formulations between pH 4.0 and 7.5. The 30 mL size is practical for testing and small-scale production.
