    ZLEY\u00ae BRC-WS \u2013 Frequently Asked Questions (FAQ)<\/strong><\/strong><\/h2>\n\n\n\n

    Q1: What is 4-Butylresorcinol (577) and why is it special?<\/strong>
    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 \u2013 issues that are effectively solved by ZLEY\u00ae BRC-WS encapsulation technology.<\/p>\n\n\n\n

    Q2: How does ZLEY\u00ae BRC-WS solve solubility and stability problems?<\/strong>
    A: It uses hydroxypropyl-\u03b2-cyclodextrin (HPBCD) to form supramolecular vesicles that encapsulate 4-Butylresorcinol. This makes the complex fully water\u2011soluble, protects it against oxidation and light, and results in a transparent, stable, and gentle brightening ingredient.<\/p>\n\n\n\n

    Q3: Are there special storage requirements?<\/strong>
    A: Yes. Due to its phenolic nature, store both the raw material and finished products in light\u2011protective (opaque or amber) containers, in a cool, dry place. Proper storage ensures excellent stability.<\/p>\n\n\n\n
