Using Erythrulose for Tanning

Erythrulose, like EasyTan™ (Erythrulose), is a sugar that creates a tanning effect by reacting with amino acids in the skin (the Millard reaction). This reaction develops color on the skin over 2-10 days, depending on the concentration used.

It is often used in self-tanning formulations, frequently combined with DHA (Dihydroxyacetone). While DHA tends to produce a brown tone, Erythrulose typically results in a blacker tone. It also has moisturizing properties, which can be beneficial as DHA can sometimes dry the skin.

How to Use:
Erythrulose is used as an ingredient in cosmetic formulations. The typical usage rate in a self-tanning formula is 1-10%, often alongside DHA. It is soluble in water.

Stability Considerations:

• Avoid temperatures above 40°C as it degrades quickly.
• Optimal stability is below 10°C (refrigerator).
• Moderate stability at 25°C.
• Deteriorates faster at pH levels above 5.0 (optimal pH is 2.5-3.5).

How long does 5 grams last?
5 grams is a small amount of the raw ingredient. How long it lasts depends entirely on the concentration you use in your final formulation and the amount of that final product you apply per use. For example, if you make a large batch of lotion using a low concentration, 5 grams would be used up quickly in the manufacturing process, but the resulting lotion would last for many applications. If you make a small batch at a high concentration, the 5 grams might yield less final product, but each application would deliver more of the active ingredient. Without knowing the specific formulation and application amount, it's not possible to determine how many uses 5 grams of the raw ingredient would last.
