ZLEY® BRC-WS – Frequently Asked Questions (FAQ)
Q1: What is 4-Butylresorcinol (577) and why is it special?
A: 4-Butylresorcinol (577) is a powerful tyrosinase inhibitor. It is 2.5 times more effective than Kojic Acid and 22 times more effective than Arbutin. However, free 4-Butylresorcinol has poor solubility, low stability, and potential irritation – issues that are effectively solved by ZLEY® BRC-WS encapsulation technology.
Q2: How does ZLEY® BRC-WS solve solubility and stability problems?
A: It uses hydroxypropyl-β-cyclodextrin (HPBCD) to form supramolecular vesicles that encapsulate 4-Butylresorcinol. This makes the complex fully water‑soluble, protects it against oxidation and light, and results in a transparent, stable, and gentle brightening ingredient.
Q3: Are there special storage requirements?
A: Yes. Due to its phenolic nature, store both the raw material and finished products in light‑protective (opaque or amber) containers, in a cool, dry place. Proper storage ensures excellent stability.
