What the Science Says
Dicaprylyl ether is a synthetic fatty ether derived from caprylic acid (a medium-chain fatty acid found in coconut oil). It is primarily used in cosmetics and skincare as an emollient and skin-conditioning agent, giving products a light, silky texture. The only available safety review confirms it is safe for topical cosmetic use — there is no published clinical research supporting its use as an oral dietary supplement.
What It Doesn't Do
No evidence it provides any internal health benefit when taken orally. Not a proven fat burner, energy booster, or metabolic aid. Don't confuse it with caprylic acid (C8 MCT oil) — they are different compounds with different research profiles. No clinical trials support any supplement claim.

Absorption & Bioavailability
Unknown — no human absorption or pharmacokinetic data available for oral use. Topical absorption is considered minimal based on cosmetic safety assessments.
Red Flags to Watch For
- This ingredient has zero published clinical trials as a dietary supplement — any health claims are unsupported by evidence.
- It is primarily a cosmetic ingredient, not a supplement ingredient — its presence in supplement products is unusual and unexplained by research.
- Do not confuse with caprylic acid (MCT C8), which has actual nutritional research behind it — dicaprylyl ether is a different molecule.
- No established safe oral dosing exists — the 15 registered supplement products containing it have no clinical basis for their formulations.
- Regulatory safety data covers only topical cosmetic use, not oral ingestion.
