We prefer ethanol as our solution for dilution in our MRF blends💧 Ethanol dilutes the oils in our blends best, making our blends clear, smooth and well rounded. We are finding that carrier oils are not blending our thick base note oils well, causing a less diluted and clear blend. We want our customers to know that Natural Essential Oils blend best in ethanol and the ethanol-based blend will last much much longer since ethanol is a great preservative! We offer this information for those not sure which carrier they prefer. Of course, if our customer requests an oil-based carrier perfume we will deliver on this ❣️ On a final note... We truly want our customers to always be happy with their purchase with MRF🧡
