Myristic acid, also known as tetradecanoic acid, is a saturated fatty acid commonly found in various vegetable oils and animal fats [1]. It is a white or slightly yellow crystalline solid at room temperature and is practically insoluble in water [2]. The substance is a straight-chain fatty acid composed of 14 carbon atoms.

Myristic acid is commercially produced through the saponification and fractional distillation of natural oils such as coconut oil, palm kernel oil, and nutmeg oil [3]. Saponification involves the alkaline hydrolysis of triglycerides in these oils. The resulting fatty acid mixture is then separated by fractional distillation based on boiling points, isolating myristic acid [4]. This process yields a high-purity product suitable for cosmetic and industrial applications.

The compound functions primarily as a surfactant, emulsifier, and opacifier in cosmetic formulations [5]. As a surfactant, it helps to reduce the surface tension between liquids, allowing for better mixing of oil and water [6]. As an emulsifier, it stabilizes emulsions, preventing separation of ingredients in creams and lotions [7]. Its opacifying properties can enhance the visual appeal of products, providing a pearlescent effect [8].

The acid is used in a wide array of personal care products, including soaps, cleansers, shampoos, shaving creams, and moisturizing lotions [9]. In soaps and cleansers, it contributes to the foaming and cleansing action [10]. In shampoos, it can improve the texture and feel of the product [11]. In creams and lotions, it aids in creating a smooth, stable emulsion that enhances skin feel [12].

Myristic acid should be stored in tightly closed containers in a cool, dry, and well-ventilated area to prevent degradation [13]. During transportation, it should be protected from physical damage and extreme temperatures to maintain its quality. Standard packaging typically involves placing the material in polyethylene bags inside fiber drums or boxes [14].
