MCT Oil is a commonly used diluent/carrier across a variety of industries and can be used as a generalized easy-to-use, inexpensive, and pure thinner to control viscosity. This is just a higher purity, completely flavorless, and much more effective form of it than other sellers carry online. It has been added to the site as a popular request and affordable price. The manufacturer of this MCT oil diluent has precisely refined the materials to contain only Caprylic acid (C8), reporting an impressive 99.8% purity. No long chain fatty acids like other online suppliers. Diluents work best in lower percentages so go easy on the mixing ratios. 10% is generally plenty.
