“When the grace period ends in 2026, will your formulation still be safe at 1 ppm?”

The 2 ppm lead allowance under the Washington State TFCA is only a temporary policy valid until the end of 2026. Once the grace period expires and the legal principle of the 1 ppm standard is fully enforced, today’s borderline formulations could become a major risk for global market expansion.

Limitations of Conventional Approaches

-Passive Verification :Uncertain validation relying solely on raw material CoA values

-Process Inefficiency : Rising costs and reduced productivity caused by repeated purification processes

-Accelerating Regulations : A global trend toward stricter limits, including Germany’s standard of below 2 ppm

It is time to move beyond temporary fixes.
A fundamental solution that surpasses regulatory requirements is now essential.

PureZn-AS achieves an extreme level of purity that surpasses even the global benchmark of 1 ppm.
Even amid regulatory uncertainty, it delivers unmatched reliability worldwide without the need for formulation changes.

In this issue, we reveal the technical foundation behind PureZn-AS, and how it proactively safeguards against evolving global regulations while enabling a truly compliant formulation.

■ Introduction to PureZn-AS

Conventional zinc oxide materials often rely on batch selection to meet heavy metal limits or remain at levels that only barely comply with regulatory thresholds.

In contrast, PureZn-AS secures a clear Safety Margin, delivering ultra-high purity mineral UV protection that enables unified compliance with increasingly stringent global heavy-metal regulations using a single material.

PureZn-AS promises the 3C principles : Clean purity, Clear transparency beyond limits, and Consistent uniformity without variation.

■ Core Strength of PureZn-AS: Defect-Free Process Powered by a Smart Factory

Conventional zinc oxide production often relies on selecting specific batches to meet regulatory specifications.
PureZn-AS, however, has fundamentally transformed the manufacturing process itself.

-Unmatched Purity (Clean)
:Large-scale hardware investment and a fully automated AI-controlled production system effectively eliminate external contamination sources.

-Consistent Quality (Consistent)
:A data-driven, high-precision purification process ensures a uniformly low heavy-metal profile across every production lot, without variability.

-Safety Margin
:One single material provides integrated compliance not only with current regulations but also with future, increasingly stringent global guidelines.

■ UV Protection and Formulation Excellence of PureZn-AS

PureZn-AS goes beyond safety by overcoming the inherent limitations of conventional mineral UV filters.

Through uniform particle size design and innovative surface treatment technology, it significantly reduces the whitening effect and enables highly transparent formulations.

In addition, PureZn-AS maintains low reactivity even in hybrid organic–mineral systems, providing excellent formulation stability and long-lasting performance. As a result, SPF and PA levels remain stable over time without degradation.

■ Benefits of PureZn-AS from a Formulation Perspective

Purified through an ultra-high purity refining process, PureZn-AS delivers the following benefits for safety-critical formulations.

-Extreme purity exceeding the strictest global benchmark (2 ppm), enabling unified compliance with worldwide regulations

-Exceptional safety for ingestible makeup formulations, such as lipsticks and lip balms

-Minimized risk of irritation in infant and baby care products, including diaper rash creams and baby sun care.

-Optimized for sensitive-skin foundations and clean beauty certification standards

Superior dispersibility, enabling transparent formulations without whitening and ensuring uniform texture

PureZn-AS is the next-generation ultra-high-purity mineral UV filter that remains resilient amid evolving global regulations.
