L-Erythrulose

L-Erythrulose is also called Erythrulose or DHB which is a natural ketose that appears as a yellow, highly viscous liquid and needs to be refrigerated. L-Erythrulose is generally used in combination with 1,3-Dihydroxyacetone(DHA) to deepen the color of DHA and make its distribution more even. L-Erythrulose is a self-tanning agent for smooth tanning of the skin.

Product Introduction

L-Erythrulose is a natural ketose that appears as a yellow, highly viscous liquid and needs to be refrigerated. L-Erythrulose is generally used in combination with DHA to deepen the color of DHA and make its distribution more even. In addition, high-purity L-Erythrulose can form a lasting brown skin and is often used as a tanning agent. L-Erythrulose has moisturizing, anti-oxidation and skin tone regulating effects. L-Erythrulose is a natural tanning ingredient that provides a more realistic, more even and longer-lasting tanning effect.

As a natural ketose, Erythrulose is widely used in the cosmetics industry, especially as a tanning agent. L-Erythrulose can react with keratin amino acids on the outside of the skin or in the dead surface layer, turning the skin brown, thus achieving a tanning effect. L-Erythrulose has the advantages of slowly darkening the skin, producing a natural, homogeneous and lasting tan, no special smell, skin safety, and moisturizing the skin.

Erythrulose is a hyaluronic acid monomer which is the basic composition unit of important organism polysaccharides. It extensively exists in the exoskeletons of shellfish and has become a new type of biochemical drugs, drug intermediates , high-end cosmetics and food additives for the important functions, such as immunity enhancement, antioxidant, keeping moisture, anti-free radicals, etc.

In cosmetics, the combination of L-Erythrulose and Dihydroxyacetone (DHA) can deepen the color and distribute DHA more evenly. This joint use method is formulated at concentrations of 1% -3% and in aqueous phase below 40 ºC. The function of L-Erythrulose is not only to deepen the color, but also to react with the free amino groups of keratin in the epidermal stratum corneum, producing a coloring effect similar to the Meidra reaction. This reaction mechanism is similar to the dynamic process of natural sun tanning, but it can avoid the damage of sun exposure to the skin and protect the skin from UV damage. Therefore, the application of L-Erythrulose in tanning products can provide a natural, long-lasting, and stripe free tanning effect, while avoiding the inconvenience and potential risks of traditional sun exposure.

L-Erythrulose is a natural ketose. It is a water-soluble, high-purity, non-tanning tanning product fermented by non-pathogenic bacteria. This mechanism is similar to the dynamics of natural sun tanning, while protecting delicate skin from the sun and UV rays. Erythrulose (L-Erythrulose) is a natural, fermented, and water-soluble keto-sugar that is used in sunless tanning cosmetics.

L-Erythrulose is typically used in self-tanning formulas in conjunction with Dihydroxyacetone(DHA) to improve color, reduce streaking, and reduce skin dryness, thus enhancing and extending the user’s tan. L-Erythrulose induces a Maillard-like reaction with amino groups in the upper layers of the epidermis which produces a temporary browning effect with an appearance similar to a natural sun tan.
