Erythrulose

Product Description

Erythrulose is a premium, naturally derived keto-sugar widely used in modern sunless tanning formulations to deliver gradual, natural-looking color development. Manufactured under controlled production and purification processes, it ensures high purity, batch-to-batch consistency, and reliable performance for cosmetic manufacturers worldwide.

Through a controlled Maillard reaction with amino groups present in the outermost layers of the stratum corneum, Erythrulose progressively develops an even-toned tan that closely mimics the appearance of naturally sun-kissed skin. Compared with fast-developing tanning systems, its slower color evolution helps minimize streaking and harsh transitions while promoting a softer, more authentic finish.

Driven by increasing consumer demand for UV-free tanning alternatives, Erythrulose offers formulators a versatile solution for premium body care concepts focused on natural radiance, improved color uniformity, and customizable tanning experiences with enhanced sensory appeal.
