Lavender oil 40/42 is a commercial grade, economical Lavender oil with a sweet, floral, and herbal aroma. This is an affordable alternative to more expensive and pure Lavender oils, while still providing a wonderful Lavender scent. Lavender 40/42 oil is not recommended for therapeutic use due the common practice of blending Lavandin, but works wonders for products with this desired aromatic profile.
