What is the Meaning of Carrier Oil?

A carrier oil is a non-volatile, lipid-based vehicle used in transdermal or topical preparations to dilute and facilitate the absorption of highly concentrated active pharmaceutical ingredients, such as bioidentical hormones. These oils are chemically stable, possessing a favorable molecular structure that allows for effective penetration through the stratum corneum of the skin. They are essential components in compounding pharmacy, ensuring accurate dosing and patient tolerability of topical hormonal therapies.

What is the Origin of Carrier Oil?

The practice of using fatty oils as a base for medicinal applications dates back to ancient pharmacology and herbalism, utilized for centuries to deliver active plant compounds through the skin. In modern clinical practice, the term became formalized within compounding standards as a necessary excipient for lipophilic drugs, particularly steroids. This use is dictated by the physicochemical properties required for optimal transdermal delivery.

What is the Mechanism of Carrier Oil?

The carrier oil functions by temporarily disrupting the lipid matrix of the skin's outermost layer, the epidermis, which enhances the passive diffusion of the dissolved hormone molecules. The lipophilic nature of steroid hormones allows them to readily dissolve in the oil base, facilitating their passage across the skin barrier and into the systemic circulation. Different carrier oils possess varying viscosities and fatty acid profiles, influencing the rate and extent of drug absorption.
