Overview
Fractionated coconut oil, also called medium-chain triglyceride or MCT oil, stays liquid at room temperature and adds little odor. It makes beard oils easier to spread and makes wax-heavy balms or salves feel less stiff and resistant on first touch.
It does not add firmness or hold. Use it to loosen a dense blend and lighten the finish, then keep enough wax or butter for the structure the container needs. Follow the supplier's storage guidance and compare a small test batch at both cool and warm room temperatures.
