Panoramica del prodotto<\/strong><\/strong><\/h3>\n\n\n\n

ZLEY\u00ae BRC-WS, also known as 577 Supramolecular Vesicles<\/strong>, features advanced supramolecular vesicle technology for sustained release, using hydroxypropyl-\u03b2-cyclodextrin (HPBCD) to encapsulate 4-Butylresorcinol (also known as 577 or Rucinol). This proprietary technology solves the water solubility challenge of 4-Butylresorcinol, enhances its stability, improves skin penetration, and increases its mildness. The result is a water-soluble, transparent, stable, long-acting, gentle brightening product with excellent safety and efficacy.<\/p>\n\n\n\n

ZLEY\u00ae is a professional supplier of BRC-WS, providing stable quality, technical support, and global delivery services covering over 60 countries.<\/p>\n\n\n\n

    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

    D4: Come richiedere campioni, documentazione tecnica e prezzi?<\/strong>
