Product Introduction

Mineral oil is a transparent, colorless, and nearly odorless oil primarily derived from petroleum. It is categorized as a mixture of higher alkanes from a mineral source, in contrast to vegetable oils which are plant-derived [1]. Mineral oil exists in various forms and grades, which determine its suitability for different applications. Due to its inert and non-comedogenic properties, mineral oil is a widely used ingredient in the cosmetic industry [2].

Production Process

The production of mineral oil involves several refining processes, primarily starting from crude oil. The initial step is distillation, which separates crude oil into different fractions based on boiling points. The fraction used for mineral oil production is then subjected to solvent extraction to remove aromatic compounds [3]. Further refining processes, such as hydrotreating or hydrofinishing, are used to improve its purity and stability, ensuring the removal of impurities and unsaturated hydrocarbons. The final product is typically filtered to achieve the desired clarity and quality [4].

Efficacy and Function

Mineral oil functions primarily as an emollient, providing a layer of hydration by preventing water loss from the skin. It is known for its occlusive properties, which create a barrier on the skin's surface, thus reducing trans-epidermal water loss (TEWL) [5]. Mineral oil is chemically inert, meaning it doesn't readily react with other substances, making it suitable for sensitive skin types and reducing the likelihood of allergic reactions. Furthermore, it has cleansing properties; it can effectively remove makeup and other oily residues from the skin [6].

Application Scenarios

In cosmetics, mineral oil is used in a wide array of products, including lotions, creams, ointments, and makeup removers. Because of its moisturizing properties, it is frequently found in baby oils and skincare products designed for dry skin [7]. Additionally, mineral oil is used in hair care products to add shine and help reduce frizz. In pharmaceutical applications, it can be found in laxatives and certain topical medications, owing to its inertness and protective qualities [8].

Packaging and Transportation

Mineral oil is typically packaged in airtight containers, such as plastic or metal drums, to prevent contamination and maintain its integrity. During transportation, it is essential to protect the containers from physical damage and extreme temperatures to avoid any degradation of the oil. Regulations for the transportation of mineral oil comply with standard practices for non-hazardous oils, ensuring safe handling and delivery [9].
