What is Vitamin B5 DL-Panthenol?
DL-Panthenol (CAS 16485-10-2), also known as pantothenol, is the racemic form of the provitamin B5 alcohol used as a humectant, moisturizing agent, and film-forming conditioner.
Where is Vitamin B5 DL-Panthenol used?
- Personal care: incorporated into shampoos and conditioners
- Skin creams and lotions: improve moisture retention and surface feel
- Pharmaceutical topical preparations: wound gels, nasal sprays, eye drops
- Polyurethane and polymer systems: reactive diol for cross-linking and chain extension
- Leave-on hair treatments: penetrates the hair shaft and reduces brittleness.
Good to know: Unlike the D-isomer, the DL form is positioned primarily for topical and industrial use where biological activity of the pure enantiomer is not required.
Commercial specifications
- Bulk supply in drums and IBCs
- Concentrations commonly at 75% or 50% aqueous solution alongside neat material
