Science
Mechanism of Action
On the skin, Neatsfoot oil functions as an emollient, delivering a significant proportion of natural fatty acids such as oleic acid (~67%) and palmitic acid (~17%). It forms an occlusive film on the skin's surface, which helps to replace evaporated natural lipids, thereby reducing transepidermal water loss and contributing to enhanced moisture retention and skin softening.

Stability
Neatsfoot oil can react vigorously with strong oxidizing acids and liberates heat when exposed to strong acids and caustic solutions. For formulation, pure neatsfoot oil is preferable to 'neatsfoot oil compound,' which may contain petroleum-derived oils.

Safety
Safety Profile
No specific safety assessments by the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) for neatsfoot oil as a cosmetic ingredient have been identified. Its FDA status for skincare applications is not clearly defined. There is a documented potential for neatsfoot oil to induce dermatitis, irritation, or redness, particularly in individuals with sensitive skin.

Verdict
While historically recognized for its emollient properties in dry skin conditions, the absence of modern safety reviews for cosmetic use and the potential for moderate irritation and comedogenicity render neatsfoot oil questionable for precision skincare formulations.
