Panthenol, also known as provitamin B5, is a versatile ingredient widely utilized in skincare, haircare, and pharmaceutical formulations. With its molecular formula C9H19NO4 and molecular weight of 205.25 g/mol, panthenol is a water-soluble alcohol derived from pantothenic acid, a member of the B-vitamin family. This transparent liquid is odorless or has a slight characteristic odor, making it suitable for incorporation into a variety of cosmetic and personal care products. Chemically, panthenol contains a hydroxyl group (–OH) and an amine group (–NH2), contributing to its moisturizing, soothing, and healing properties. Upon absorption into the skin or hair, panthenol is converted into pantothenic acid, a precursor to coenzyme A (CoA), which plays a crucial role in various biological functions.
1. Introduction to Panthenol
Panthenol, also known as provitamin B5, is a water-soluble alcohol that is a derivative of pantothenic acid, a member of the B-vitamin family. It plays a crucial role in various biological functions, particularly in skincare, haircare, and pharmaceuticals. Panthenol is widely recognized for its moisturizing, soothing, and healing properties, making it a popular ingredient in many cosmetic and personal care products.
2. Chemical Structure and Properties
Panthenol has a molecular formula of C9H19NO4 and a molecular weight of 205.25 g/mol. It is a viscous, transparent liquid at room temperature and is odorless or has a slight characteristic odor. Chemically, panthenol is an alcohol, containing a hydroxyl group (–OH) and an amine group (–NH2). It is highly soluble in water and readily penetrates the skin and hair.
3. Biological Functions
Panthenol serves as a precursor to pantothenic acid (vitamin B5) in the body. Once absorbed, it is converted into pantothenic acid, which is a component of coenzyme A (CoA). Coenzyme A is essential for numerous biochemical reactions, including the synthesis of fatty acids, cholesterol, and steroid hormones. Additionally, panthenol plays a vital role in maintaining the integrity of epithelial tissues, such as the skin and mucous membranes.
4. Benefits for Skin
Panthenol is renowned for its moisturizing and humectant properties, which help attract and retain moisture in the skin. It enhances skin hydration, making it soft, smooth, and supple. Moreover, panthenol has soothing and anti-inflammatory effects, making it beneficial for sensitive or irritated skin. It can help alleviate symptoms associated with various skin conditions, including eczema, dermatitis, and sunburn.
5. Haircare Benefits
In haircare products, panthenol acts as a conditioner and humectant, improving the hair’s moisture retention and elasticity. It penetrates the hair shaft, enhancing its flexibility and strength, thereby reducing breakage and split ends. Panthenol also adds volume and shine to the hair, making it appear healthier and more vibrant. It is commonly found in shampoos, conditioners, and styling products.
6. Wound Healing Properties
Panthenol has been shown to accelerate the wound healing process due to its ability to promote cell proliferation and tissue regeneration. It stimulates fibroblast proliferation, which are cells involved in producing collagen and other extracellular matrix components essential for wound repair. Additionally, panthenol exhibits anti-inflammatory effects, reducing swelling and redness around wounds, and it may help minimize the formation of scars.
7. Use in Pharmaceuticals
Beyond skincare and haircare products, panthenol is also utilized in pharmaceutical formulations for its therapeutic properties. It is often incorporated into topical ointments, creams, and lotions for treating various dermatological conditions, such as minor cuts, burns, and abrasions. Panthenol’s moisturizing and healing effects make it an effective ingredient in products designed for dry, damaged, or irritated skin.
8. Safety and Side Effects
Panthenol is considered safe for topical use and is well-tolerated by most individuals. It is non-toxic and non-irritating, making it suitable for sensitive skin types. However, in rare cases, allergic reactions may occur, resulting in skin irritation or rash. It is advisable to perform a patch test before using products containing panthenol, especially if you have a history of skin sensitivities or allergies.
9. Formulations and Application
Panthenol is incorporated into various skincare, haircare, and pharmaceutical formulations in different concentrations, ranging from 1% to 5% or higher, depending on the desired effects. It can be found in creams, lotions, serums, gels, shampoos, conditioners, and wound care products. When applying panthenol-containing products, it is essential to follow the manufacturer’s instructions for optimal results.
In skincare, panthenol is revered for its moisturizing and humectant properties, which help attract and retain moisture in the skin. By enhancing skin hydration, panthenol promotes a soft, smooth, and supple complexion while reducing dryness and flakiness. Additionally, panthenol exhibits soothing and anti-inflammatory effects, making it particularly beneficial for individuals with sensitive or irritated skin conditions, such as eczema, dermatitis, or sunburn.

Furthermore, panthenol adds volume, body, and shine to the hair, enhancing its overall appearance and manageability. Whether incorporated into shampoos, conditioners, leave-in treatments, or styling products, panthenol helps rejuvenate and revitalize dull, lackluster hair, leaving it looking healthier and more vibrant.
Panthenol’s wound healing properties have also garnered attention in the pharmaceutical industry, where it is commonly used in topical ointments, creams, and lotions for treating minor cuts, burns, abrasions, and other skin injuries. By promoting cell proliferation and tissue regeneration, panthenol accelerates the wound healing process, minimizing inflammation, swelling, and discomfort. Its ability to stimulate collagen production and enhance skin barrier function contributes to more efficient wound closure and reduced scarring. As a result, panthenol-containing products offer effective solutions for promoting skin repair and recovery while maintaining optimal moisture balance.
