PHENYLDIMETHOXYACETOPHENONE

Description

Phenyldimethoxyacetophenone, also known as PDMAP or Photoinitiator 369, is a potent photoinitiator commonly used in UV-curable coatings, inks, and adhesives. This crystalline solid compound is characterized by its white to off-white appearance and mild odor. With a molecular formula of C16H16O3, PDMAP has a molecular weight of 256.3 g/mol and exhibits excellent solubility in various organic solvents.

In skincare and cosmetic formulations, PDMAP serves as an efficient photopolymerization initiator, particularly in gel nail polish systems. When exposed to UV light, it generates free radicals that trigger the rapid curing process of monomers and oligomers, resulting in a durable, glossy finish. Its effectiveness at low concentrations (typically 0.5-3%) makes it an economical choice for manufacturers.

PDMAP demonstrates good thermal stability and compatibility with a wide range of formulation ingredients. Its low yellowing tendency contributes to the long-term color stability of cured products. While generally considered safe for cosmetic use, proper handling and protective measures are essential due to its potential skin and eye irritation properties. Ongoing research explores its application in advanced 3D printing technologies and dental materials.
