4-Butylresorcinol
CAS :18979-61-8
White to off-white powder
Whitening Agent
Molecular formula: C₁₀H₁₄O₂
This is the primary application area of 4-Butylresorcinol.
1.Mechanism of Action: Inhibits the activity of tyrosinase, thereby blocking the melanin production process and reducing hyperpigmentation.
2. Advantages:
More effective than traditional skin-lightening ingredients such as hydroquinone, arbutin, and vitamin C
Low irritation and relatively safe
Exhibits good skin penetration and formulation stability
3. Applications: Whitening serums, fade creams for dark spots, post-acne mark treatments, anti-aging skincare products, etc.
4. Regulatory Status: Approved for use in cosmetics in several countries and regions (e.g., South Korea, China, and the European Union), typically at concentrations not exceeding 0.3%.
Can be used in the synthesis of certain drugs or as an intermediate in organic synthesis, for example, in the development of antibacterial, anti-inflammatory, or hormonal agents.
Used in biochemical and dermatological research as a model compound for tyrosinase inhibition, helping to evaluate the efficacy of novel skin-lightening agents.
Irritation: Generally low, but may cause mild irritation in individuals with sensitive skin.
Photosensitivity: No significant photosensitizing effect observed; however, sunscreen use is recommended to enhance whitening results and protect the skin.
Stability: Should be stored in a tightly sealed container, protected from light to prevent oxidation and discoloration.
