D-Panthenol (Provitamin B5) is a high-purity cosmetic active with impurities by HPLC showing pantoic acid less than 0.5% and pantolactone less than 1.0%, confirming premium quality. The alcohol analogue of pantothenic acid (Vitamin B5), D-Panthenol penetrates deeply into the skin and hair shaft where it is converted to pantothenic acid — a key coenzyme in cellular metabolism and tissue repair. It is one of the most universally used and well-loved multifunctional actives in personal care, providing simultaneous moisturising, conditioning, healing, and protective benefits across both hair and skin formulations.
Applications:
- Haircare (hair conditioning, strengthening, anti-breakage shampoos, conditioners, treatments)
- Skincare (moisturising, wound healing, anti-inflammatory creams, baby care products)
- Body Care (after-sun, body lotions, post-depilation soothing formulations)
- Oral Care (gum health and wound-healing oral care formulations)
Key Features & Benefits:
- Pantoic acid <0.5% / Pantolactone <1.0% (HPLC) – high purity cosmetic grade
- Deep penetration into skin and hair shaft – converts to active Vitamin B5
- Simultaneously moisturising, conditioning, healing, and anti-inflammatory
- One of the most universally used multifunctional actives in personal care
- Suitable for hair, skin, body, and oral care formulations
D-panthenol versus DL-panthenol
Panthenol is the alcohol form of pantothenic acid (vitamin B5), and skin converts it to pantothenic acid. Only the D-form is converted; DL-panthenol is a cheaper mixture in which half the material is the inactive L-form. Check which form you are buying (specific optical rotation confirms D-panthenol) and whether it is supplied as the pure viscous liquid or diluted, for example as a 75% solution.
How to formulate with it
D-panthenol dissolves in water and alcohol and is usually added to the water phase or in the cool-down phase. It is most stable around pH 4–7; strong acid, strong alkali and long heating break it down into pantoic acid and aminopropanol, the impurities reported on the certificate. It works well alongside humectants such as Glycerine and Hyaluronic Acid, and in hair care it is used in shampoos and conditioners for softness and shine.
Claims
Moisturising and conditioning are normal cosmetic claims. Wound-healing and anti-inflammatory claims are medical claims for a cosmetic, so keep finished-product wording within what the ASEAN Cosmetic Directive allows.
What the research says
- In a randomised study of 38 people after fractional CO2 laser treatment of sun-damaged skin, each person had one area treated with a dexpanthenol ointment and another with petroleum jelly. The dexpanthenol areas healed faster on days 1–5 and looked better to patients and doctors; all areas had healed by day 14. [1]
- In a randomised trial of 101 children having adenotonsillectomy, a single application of dexpanthenol to the corners of the mouth before surgery lowered cracking at the lip corners on the first day (9.8% vs 44%), but there was no significant difference after one week and no effect on pain. [2]
- Both studies were small, used finished dexpanthenol products in medical or post-procedure settings, and do not show effects for every cosmetic use.
