d-Panthenol, also known as provitamin B5, is the alcohol analog of pantothenic acid (vitamin B5), and because of this, it exhibits the same biological activity as pantothenic acid [1]. It is a viscous, transparent, and colorless liquid at room temperature, making it easy to formulate into different cosmetic products. Moreover, d-panthenol is water-soluble and alcohol-soluble, further enhancing its versatility in formulations [2].

D-Panthenol is typically synthesized through a chemical process. One common method involves reacting isobutyraldehyde with formaldehyde to form an intermediate product, which is then reacted with 3-aminopropanol [3]. Following this, a resolution step isolates the d-isomer, ensuring the desired optical purity for cosmetic applications. The resulting d-panthenol is then purified to meet industry standards for quality and safety [4].

D-Panthenol is widely recognized for its moisturizing and humectant properties, which help hydrate the skin by attracting and retaining moisture [5]. It can also act as a skin protectant, reducing redness and irritation [6]. Studies have shown that d-panthenol can improve skin barrier function and promote wound healing [7]. Additionally, it can enhance the appearance and feel of hair, increasing its shine and manageability [8].

D-Panthenol is used in a diverse range of cosmetic and personal care products. It is found in skin creams and lotions, where it helps maintain skin hydration and elasticity [9]. In hair care products like shampoos and conditioners, it improves hair texture and luster [10]. It is also incorporated into nail care products to strengthen nails and prevent breakage [11]. Furthermore, d-panthenol is used in products designed for sensitive skin, such as baby lotions and sunscreens, due to its soothing and protective qualities [12].

D-Panthenol is generally packaged in plastic drums or containers, depending on the quantity. These containers are designed to prevent contamination and maintain the integrity of the product. During transportation, it should be stored in a cool, dry place, away from direct sunlight and extreme temperatures [13]. Standard shipping practices should be followed to ensure safe handling and delivery [14]. Proper labeling and documentation are necessary to comply with regulatory requirements [15].
