Octyl caprylate, also known as caprylic/capric triglyceride, functions primarily as an emollient and skin-conditioning agent in cosmetic formulations [1]. It is derived from coconut or palm kernel oil, through a process called fractionation, separating the caprylic and capric acids, which are then re-esterified with glycerin [2].

The production process of octyl caprylate involves several key steps. First, the triglycerides from coconut or palm kernel oil are hydrolyzed to obtain a mixture of fatty acids, including caprylic acid and capric acid [3]. These fatty acids are then purified via distillation. Finally, the purified caprylic and capric acids are esterified with glycerol under controlled conditions to form octyl caprylate [4].

Octyl caprylate provides several benefits in cosmetic applications, offering good oxidative stability, contributing to a light, non-greasy skin feel, and acting as an effective emollient [5]. It is known to improve the texture of creams and lotions, enhancing the spreadability of products on the skin [6]. Additionally, it can function as a solvent, improving the solubility of certain ingredients, such as UV filters [7].

This ingredient is suitable for a wide range of cosmetic and personal care products. It can be found in facial moisturizers, body lotions, sunscreens, and makeup products such as foundations and lipsticks, improving the overall aesthetics and performance of these formulations [8]. Its non-greasy property makes it suitable for products targeting oily or acne-prone skin [9].

Octyl caprylate is generally packaged in drums or containers, depending on the quantity. Transportation should follow standard procedures for non-hazardous materials. It should be stored in a cool, dry place, away from direct sunlight and heat, to maintain its stability and quality [10].
