Adverse effects during pregnancy are unknown but assumed minimal given the history of product use. The potential for idiosyncratic allergenicity may exist and should be forewarned, but this effect would be readily identified and reversible. Considering the high usage of lavender oil on the skin in aromatherapy, the reported incidence of skin reactions is low.Ī report commissioned by Art Tree LLC a supplier of spike lavender oil determined the following: "Evidential data are supportive that Spike Lavender Oil would not cause a chronic health effect with acute or prolonged dermal or inhalation exposure. Toxicityīoth lavender oil and lavandin oil are considered to be non-toxic and have GRAS status. The essential oil is completely natural with nothing added. intermedia Grosso) and steam distilled to high purity. Our spike oil is imported from France where it is extracted from the flowering tops of cultivated Lavandin ( Lavandula x. It has a stronger scent with a slightly different note to it and is more economical than the other lavender choices. Lavandin grosso is the source of our spike oil because of its lower cost. In general, it is a larger plant than true lavender and yields a higher production of oil. Where the two varieties tend to meet, they eventually cross pollinate and Lavandin came into being. True lavender typically grows higher in the mountains while spike lavender grows down lower. One of the lesser known materials is Lavandin grosso, which is a hybrid created from true lavender (L avendulan augustifolia) and spike lavender ( Lavendulan latifolia). Most people don’t realize there are a variety of different lavender essential oils. The addition of spike oil reduced the amount of oil binder and encouraged faster drying to prevent the blue pigment from sinking in, which is the cause of fading and/or changing to green.įor complete information about spike oil, please read Lavender Spike Oil: Source, History and Use in Painting. The large particles of these pigments are heavy and sink while the oil paint dried, giving a dull and greenish appearance to the color. These writers referred to the propensity of blue pigments, specifically azurite and smalt, to sink into the paint causing an excessive accumulation of oil to the surface. It is also an effective solvent for natural resins, such as dammar, mastic, sandarac, gum elemi and copal in conjunction with turpentine.Ĭharles Eastlake cited authors historical use of spike oil in Materials for a History of Oil Painting. Spike oil can be used to thin oil paint like other common solvents, such as turpentine. It evaporates slower than turpentine, mineral spirits (white spirits) and odorless mineral spirits (OMS). A small amount goes a long way and it has a pleasant smell unlike other solvents. However, this has not been verified by scientific testing. It is believed that spike oil improves the handling of oil-based paints, because it promotes oxidation instead of simply evaporating like most solvents. It was used historically in oil painting as early as the fifteenth century. It can be used as a solvent for oil painting and in egg-oil emulsion tempera recipes.
