Erythrulose

Cat:	DB-ST-002
CAS No.:	533-50-6; 40031-31-0
Description:	A natural keto sugar ((S)-1,3,4 trihydroxy-2-butanone) sunless tanning agent. originated from glucose; Achieves a tan that looks more natural and authentic. Often combined with DHA.provides darker, more evenly distributed tan. It reacts with free primary or second amino groups of keratin in the upper layers of the epidermis. This conversion of reducing sugar with amino acids, peptides or proteins, similar to the “Maillard reaction”, also known as non-enzymatic browning, leads to the formation of brownish polymers, the so-called melanoids. The resulting brown polymers are bound to proteins of the stratum corneum mainly via lysine side-chains. The brown color is comparable to the appearance of natural sun tan. Tanning effect appears in 2-3 days, the maximal tanning intensity is reached with Erythrulose after 4 to 6 days. The tanned appearance typically lasts from 2 to 10 days depending on application type, and skin condition.

Feature:	Erythrulose has been developed to reduce or even eliminate the disadvantages of DHA, namely an irregular and streaky tan as well as an intense drying effect. It presents a new solution for the increasing demand of self-tanning. It is a natural keto-sugar occurring in Red Raspberries, and may be produced by fermentation of the bacterium Gluconobacter followed by multiple purification steps.
Performance:	Erythrulose reacts with free primary or second amino groups of keratin in the upper layers of the epidermis. This conversion of reducing sugar with amino acids, peptides or proteins, similar to the “Maillard reaction”, also known as non-enzymatic browning, leads to the formation of brownish polymers, the so-called melanoids. The resulting brown polymers are bound to proteins of the stratum corneum mainly via lysine side-chains. The brown color is comparable to the appearance of natural sun tan. Tanning effect appears in 2-3 days, the maximal tanning intensity is reached with ERL after 4 to 6 days. The tanned appearance typically lasts from 2 to 10 days depending on application type, and skin condition. The coloring reaction of Erythrulose with skin is slow and gentle, which makes it possible to produce a natural, long-lasting, even tan without stripes (DHA may create an orange tone & stripes).
