What it is
2-Methoxy-p-Cresol is a synthetic aromatic compound derived from guaiacol. It is a clear to pale yellow liquid with a strong, smoky, phenolic odor, often used in perfumery to add depth and complexity to fragrances.
How it works
In a cosmetic product, 2-Methoxy-p-Cresol functions solely as a fragrance ingredient. It does not provide any skincare benefits like moisturizing or exfoliating.
