    Product Details

    Typical Properties
    Item Specifications
    Appearance Light Yellow Powder
    Purity ≥98%
    Melting Point ≥80℃
    Core Sun Protection Performance
    1 Absorption Spectrum (280–380 nm, Full-Wave Coverage)

    UVB (280–320 nm): Peak absorption at 310 nm. Provides strong protection against sunburn and redness.

    UVA (320–380 nm): Peak absorption at 343 nm. Highly effective in defending against photoaging, dark spots, and skin laxity.

    2 Photostability (The "Anchor" of the Formula)

    The triazine ring structure is highly resistant to photodegradation, ensuring that sun protection efficacy remains durable and does not decay under sun exposure.

    Capable of stabilizing easily decomposing filters (such as Avobenzone), significantly enhancing the overall stability of the formulation.

    3 Mechanism of Action

    Upon absorbing UV radiation, it converts light energy into harmless thermal energy for release, without damaging the skin.

    With a high molecular weight of 627.8, it is not easily absorbed through the skin, resulting in extremely low irritation.

    Core Advantages
    Broad-Spectrum Protection
    Simultaneously covers UVA/UVB, delivering dual defense against tanning and photo-aging.
    Ultimate Photostability
    Durable sun resistance; remains stable and highly effective even under intense outdoor UV exposure.
    Hypoallergenic Safety
    Large molecules that do not penetrate the skin; mild with low irritation, making it suitable for sensitive skin.
    Formula Friendly
    Excellent compatibility with oils and other sunscreen agents (such as Octocrylene and Titanium Dioxide).
    Eco-Friendly
    Non-toxic to coral reefs and compliant with marine environmental protection standards.
