What it is
Capryloyl Salicylic Acid is salicylic acid modified with a caprylic (C8) fatty chain, which makes it more oil-loving than standard salicylic acid. This lipophilic character gives it an affinity for the skin's surface lipids and supports gentle, gradual exfoliation and smoothing of skin texture. It is used in conditioning and refining formulations, including some daily-care sunscreens.
Safety & warnings
As a salicylic acid derivative, Capryloyl Salicylic Acid may cause mild tingling, dryness, or sensitivity in some users, particularly with frequent use or on already-compromised skin. It is not a recognized fragrance allergen; introducing it gradually can help reactive skin adjust.
Origin & sourcing
Synthetic, produced by attaching a caprylic acid chain to salicylic acid.
