Erythrulose is a self-tanning and bronzing ingredient used in cosmetics for its ability to react with amino acids present on the outer layer of the skin - leading to a tanned appearance. A natural ketose sugar, it is often combined with dihydroxyacetone (DHA), another self-tanning agent, to create a more natural and longer-lasting tan. Further, Erythrulose helps reduce streaking and patchiness often associated with self-tanners. Its slower reaction time gives users more control over the even application of the product. In its raw form, Erythrulose appears as a clear to pale yellow liquid with a slightly syrupy texture. Additionally, Erythrulose is better than DHA since it produces a more natural-looking tan, has longer-lasting results, and is less drying.

What is ERYTHRULOSE used for?
Erythrulose is primarily used in self-tanning products due to its ability to produce a natural-looking tan without streaking. It reacts with amino acids in the skin, creating a bronzed appearance over 24 to 48 hours, which provides a more gradual and even color compared to other agents like DHA. Erythrulose is commonly found in various formulations, including self-tanning lotions, sprays, creams, and gradual tanners, as well as bronzing products. Its gentle nature makes it suitable for sensitive skin, and it is often combined with DHA to enhance tanning effects while minimizing skin irritation and promoting longer-lasting results.
Origin
Erythrulose is made through biotechnological fermentation of plant-based biomass or algae. The process involves cultivating specific microorganisms, typically bacteria or algae, that convert sugars into Erythrulose through enzymatic reactions. After fermentation, the Erythrulose is extracted, purified, and concentrated for use in cosmetic formulations. Its chemical formula is C4H8O4.

TANNINGSafety Profile
Erythrulose is generally considered safe for use in cosmetics, exhibiting low irritation potential and being non-toxic. It is suitable for sensitive skin and does not increase sun sensitivity. Regulatory bodies, including the Cosmetic Ingredient Review (CIR) and SCCS, approve its use in both leave-on and rinse-off products. However, like all cosmetic ingredients, some individuals may experience allergic reactions. It is crucial to perform patch tests before widespread application, especially for those with sensitive skin or allergies.
