E166 - Bois de santal

Origin

E166, also known as Sandalwood, refers to colorants derived from sandalwood trees, primarily *Santalum album*. These trees are native to India, Australia, and other parts of Asia. The colorant is extracted from the heartwood of the sandalwood tree, which is known for its aromatic properties and use in traditional medicine and perfumery. The colorant is typically a reddish-brown hue.

Usage

Sandalwood extract is used as a natural food coloring agent, providing a reddish-brown to brown color to various food products. It has been used in confectionery, beverages, and traditional sweets. Beyond food, sandalwood extracts are widely used in cosmetics, perfumes, and incense due to their characteristic fragrance. Its use as a food colorant is less common compared to other synthetic or natural colorants.

Side Effects

There is limited scientific literature specifically addressing the safety of sandalwood extract as a food colorant. However, sandalwood oil and extracts have been associated with allergic reactions in some individuals, particularly when applied topically. These reactions may include contact dermatitis, itching, and redness. Ingestion of large quantities of sandalwood extract could potentially lead to gastrointestinal discomfort. Due to the limited data on its safety as a food additive, caution is advised, especially for individuals with known allergies to sandalwood or related substances.

Regulatory Status

The regulatory status of sandalwood extract as a food colorant varies by region. It is important to check local regulations to determine if it is approved for use in food products. In some regions, it may be permitted as a natural colorant, while in others, its use may be restricted or prohibited due to a lack of comprehensive safety data. There is no established Acceptable Daily Intake (ADI) by major regulatory bodies like EFSA or FDA specifically for sandalwood extract as a food colorant.
