About botouseneco · Est. 2015
Hebei Senzhijia Environmental Protection Co., Ltd develops, manufactures and tests 23 indoor air treatment formulations in six product lines — for contractors, furniture factories, hotels and distributors worldwide.
01How we work
We control the chemistry from synthesis to the documents that travel with each drum, so what you test as a sample is what arrives in bulk.
01Formulation & synthesis lab
Every formulation starts in our Botou laboratory. Whether we are grafting reactive amino-polymers that lock formaldehyde irreversibly or stabilising 5–10 nm visible-light anatase TiO₂ sols, the target is permanent chemical conversion — without secondary off-gassing, staining or masking fragrance.
02Production & bulk supply
Our filling lines in the Botou Industrial Zone — about 180 km from Tianjin Port — serve domestic remediation contractors and overseas distributors alike. For export partners, 10X and 5X concentrates are diluted at destination, cutting freight volume and drum waste.
03Verification & traceability
Before dispatch, each batch is checked for pH, active solids and dispersion stability, and verified in closed-room testing. Every shipment leaves with an English technical data sheet (TDS), a GHS-format MSDS/SDS and a batch certificate of analysis (COA).
02Brand film
Why new interiors keep releasing formaldehyde, how our water-based scavengers, photocatalyst coatings and odor treatments work together, and how we formulate, fill and ship from Botou, Hebei. English, 1080p.
03Timeline
Synthesis and blending lines for amino-acid formaldehyde scavengers and plant-extract deodorizers.
Neutral-pH 5–10 nm photocatalyst coatings and silver-ion antimicrobial sols for indoor LED activation.
Thermal extraction, amino cross-linking and photocatalytic coating standardised for commercial handovers.
Expanded to 23 formulations across six lines, including 10X/5X masterbatches and ClO₂ slow-release media.
04For partners
Distributors, brands and contractors work directly with our formulation and export teams — no trading intermediary.
OEM & private label programLed by CEO PIN and COO Jyen (5+ years in indoor air quality chemistry and B2B operations), providing fast digital specification matching and dosage schedules.
Adjust active concentration, scent profile and viscosity for your climate and substrates, with private-label bottling from 500 mL to 1,000 L IBC totes.
Every formulation includes an encrypted, read-only English TDS specification sheet, GHS-format MSDS/SDS and lot-numbered COA prepared for sea and land freight.
Dosage schedules, HVLP nozzle settings and closed-room re-test windows directly from Jyen and our Botou engineering desk (info@senhomedustcollect.com).
