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

ZLEY\u00ae BRC (INCI: 4-Butylresorcinol) is a potent brightening agent that acts directly on the active center of tyrosinase within melanosomes. It inhibits both tyrosinase activity and tyrosinase-related protein-1 (TRP-1) activity, blocking melanin formation while promoting tyrosinase degradation. In addition, it accelerates the breakdown and elimination of existing melanin. This dual mechanism reduces skin pigmentation and fades dark spots without causing cytotoxicity to melanocytes.<\/p>\n\n\n\n

ZLEY\u00ae is a professional supplier of 4-Butylresorcinol (CAS 1135-24-6), providing stable quality, technical support, and global delivery covering over 60 countries.<\/p>\n\n\n\n

ZLEY\u00ae BRC \u2013 Frequently Asked Questions (FAQ)<\/strong><\/strong><\/h3>\n\n\n\n

Q<\/strong>1<\/strong>: Why is EDTA disodium required in formulations with ZLEY\u00ae BRC?<\/strong><\/p>\n\n\n\n

A: 4-Butylresorcinol has a tendency to chelate (bind with) metal ions<\/strong>, particularly iron and copper. This chelation can lead to discoloration and reduced efficacy. EDTA disodium<\/strong> acts as a chelating agent that binds these metal ions preferentially, preventing them from interacting with the 4-Butylresorcinol and ensuring product stability and performance.<\/p>\n\n\n\n

Q<\/strong>2<\/strong>: What are the optimal pH and solubility characteristics of ZLEY\u00ae BRC?<\/strong><\/p>\n\n\n\n

A: ZLEY\u00ae BRC is solubile in olio<\/strong> (melting point \u2248 50\u00b0C) and should be incorporated into the oil phase of formulations. It is stable within pH 4\u20138<\/strong>, with neutral to slightly acidic pH being optimal for long-term stability. Avoid highly alkaline conditions (pH > 8) as these may degrade the active.<\/p>\n\n\n\n

Q<\/strong>3<\/strong>: Are there any colorants or ingredients that are incompatible with ZLEY\u00ae BRC?<\/strong><\/p>\n\n\n\n

A: Yes. ZLEY\u00ae BRC is incompatible with carmine and acid red colorants<\/strong>. If color is required in the final product, alternative colorants should be selected. Compatibility testing is always recommended when combining 4-Butylresorcinol with any new ingredients.<\/p>\n\n\n\n
