Technical Advantages
The core of product innovation lies not in the accumulation of technical specifications, but in a sincere response to real-life situations.
We focus on material safety and brush head hygiene—because quality improvements are only meaningful when the foundation is solid. This is the essence of innovation we uphold, and it is our commitment to every user.
Our core technological advantage lies in the antimicrobial properties of our bristle material. We commissioned the Institute of Physical Chemistry, Chinese Academy of Sciences—a leading testing authority in China in the interdisciplinary field of materials and microbiology—to evaluate the antimicrobial efficacy of these PBT volcanic ash carbon bristles. The conclusions drawn from standard testing methods are clear: against Escherichia coli (a representative Gram-negative bacterium) and Staphylococcus aureus (a representative Gram-positive bacterium), the bristles’ antibacterial rate exceeds 99.9%. This result not only far exceeds the national minimum requirement of ≥90% for antibacterial products but also achieves the industry-leading “strong antibacterial” level.
Volcanic clay is rich in various mineral elements and features an active microporous structure, enabling it to effectively adsorb bacteria and disrupt the integrity of their cell membranes; carbon materials, meanwhile, possess excellent electrical conductivity and redox properties, which can interfere with microbial respiratory metabolism. Bristle filaments made by combining these two materials with a PBT matrix maintain stable surface potential and antibacterial activity even in the high-humidity environment of a bathroom. In simulated long-term wet-use testing, the antibacterial rate declined by less than 0.1% after hundreds of wet-dry cycles, truly achieving “long-lasting antibacterial protection.” For bathroom brushes, this means the brush head remains in a highly clean and hygienic state from the first use to the last disposal. Not only do we provide traceable test reports, but we also infuse this scientific rigor into every single bristle.
We have completed monitoring for specific hazardous substances under California’s Proposition 65. The monitoring program covers bisphenol A, lead, cadmium, and phthalates (including common types such as DEHP, DBP, and BBP). Proposition 65 was enacted by the State of California in 1986; its official name is the Safe Drinking Water and Toxic Enforcement Act. The law requires that any product sold in California that contains carcinogenic or reproductive toxic substances in excess of safety limits must bear a clear warning label; failure to do so constitutes a violation of the law. Our products have passed these tests, meaning that the levels of all substances tested are below the “safe harbor” levels specified by the law (No Significant Risk Level, NSRL, or Maximum Allowable Dose Level, MADL).
Specifically: Bisphenol A, as an endocrine disruptor, has an extremely low MADL value (3 micrograms per day for adults via oral exposure); the NSRL for lead is 0.5 micrograms per day; the NSRL for cadmium is 4.1 micrograms per day; and phthalates each have strict limit values. Our products have been tested by a third-party accredited laboratory using high-precision analytical methods such as LC-MS/MS and ICP-MS, and no concentrations exceeding the limits were detected for any of the four parameters mentioned above. This not only demonstrates the purity of our raw materials but also reflects our ability to control contaminants throughout the entire manufacturing chain—from injection molding and wire drawing to assembly. This monitoring confirms that our products meet global compliance requirements for safety, quality, and environmental protection. We will continue to use the strictest regulations as our benchmark to ensure that every batch of our products stands up to scientific scrutiny.

A truly trustworthy brand dares to subject its products to the most rigorous certification systems. We have obtained international authoritative quality and safety certifications such as FDA, CE, FCC, PSE, and RoHS—this is not a list meant to show off, but rather a testament to our profound sense of responsibility. Each certification represents a country or region’s deepest understanding of consumer safety: The FDA ensures that materials meet food- and drug-grade contact standards, meaning that even microscopic particles shed from the brush head must be non-toxic. CE certification ensures that the entire device can still protect users from harm under both normal use and single-fault conditions. FCC certification focuses on electromagnetic “etiquette” amid trends toward wireless and high-frequency technology, preventing products from becoming hidden sources of interference. PSE certification addresses electrical leakage and fire safety in Japan’s uniquely humid living environments. RoHS certification addresses the long-term impact of product disposal on soil and water sources, reflecting our company’s commitment to the future of the planet.
It is no coincidence that we have obtained all these certifications simultaneously. This success stems from the blacklist of hazardous substances, electromagnetic pre-compliance design rules, and biocompatibility database that we established during the R&D phase. Before each product is sent for testing, we conduct internal screening tests that are three times stricter than the standard limits. As a result, when our products actually enter the certification laboratories, they often pass on the first attempt. We have obtained internationally recognized quality and safety certifications such as FDA, CE, FCC, PSE, and RoHS, which in themselves attest to our R&D capabilities, supply chain management expertise, and unwavering commitment to user health. When you choose our products, you’re not just choosing a marketing slogan—you’re choosing a brand that has been repeatedly validated by the world’s most stringent regulatory systems. We never compromise on safety, because a brand’s standing is always determined by its safety standards.
