<\/figcaption><\/figure>\n\n\n\n

ZLEY\u00ae VCE (CAS 86404-04-8) is a highly stable derivative of Vitamin C. Through ethyl group modification at the third carbon position, it effectively prevents oxidation and ionization, resulting in significantly enhanced stability. This ingredient inhibits tyrosinase activity, blocks melanin production, and scavenges free radicals, offering both skin brightening and antioxidant benefits. Its unique molecular structure gives dual water and oil solubility, allowing it to easily penetrate the stratum corneum. Once absorbed, it is broken down by biological enzymes to release the full active form of Vitamin C.<\/p>\n\n\n\n

ZLEY\u00ae is a professional supplier of this raw material, providing consistent quality, technical support, and delivery services to over 60 countries worldwide.<\/p>\n\n\n\n

Frequently Asked Questions About ZLEY\u00ae VCE<\/strong><\/p>\n\n\n\n

Q1: What are the advantages of ZLEY\u00ae VCE compared to pure Vitamin C?<\/strong>
ZLEY\u00ae VCE solves three major issues associated with pure Vitamin C:
\u2460 Alta stabilit\u00e0:<\/strong> It is resistant to oxidation and discoloration.
\u2461 Delicato e a bassa irritabilit\u00e0:<\/strong> Suitable for sensitive skin.
\u2462 Excellent Penetration:<\/strong> Its dual water and oil solubility allows for better absorption into the skin.<\/p>\n\n\n\n

Q2: How effective is its skin-brightening action?<\/strong>
At a concentration of 20.0 g\/L, it demonstrates a tyrosinase inhibition rate of 88.63%. Its whitening mechanism involves: directly inhibiting tyrosinase activity, suppressing \u03b1-MSH through the Nrf2 pathway, and inducing autophagy in melanocytes to degrade melanin.<\/p>\n\n\n\n

Q3: What are the optimal pH and temperature for use?<\/strong>
The optimal conditions for stability are pH 5.46 and a temperature of 36.3\u00b0C. pH has a significant impact on its stability, so it is recommended to incorporate a buffer system in the formulation to maintain the ideal pH. Temperature has a relatively minor effect on its stability.<\/p>","protected":false},"excerpt":{"rendered":"
