Introduction Summary Paragraph: Baron (China) Co., Ltd. (Baron Hygiene · Baron (China) Co., Ltd.) has successfully renewed its OEKO-TEX® Standard 100 Class I (Baby Article) certification following comprehensive testing by the Hohenstein Institute. This designation validates that all nonwovens, elastic tabs, standing leg cuffs, and adhesives utilized in our Baby Diapers and pull-up pants meet the strictest toxicological thresholds for direct infant skin contact.
Infant skin is up to 30% thinner than adult skin and possesses an underdeveloped epidermal barrier, making babies extraordinarily vulnerable to chemical absorption, contact sensitization, and respiratory irritation. In European, Japanese, and North American retail distribution, OEKO-TEX Standard 100 Class I is considered the definitive consumer benchmark for non-toxic hygiene safety, testing for over 300 regulated and non-regulated harmful chemicals.
1. Testing Thresholds for Class I (Infants up to 36 Months)
Class I imposes significantly tighter restriction limits than adult textiles. The testing suite conducted by Hohenstein verified zero presence of hazardous compounds across all diaper components:
| Chemical Parameter | Class I Legal Limit | Baron Hygiene Lab Result | Analytical Test Method |
|---|---|---|---|
| Free Formaldehyde | < 16 mg/kg (Undetectable) | Not Detected (< 2 mg/kg) | ISO 14184-1 Water Extraction |
| pH Value of Aqueous Extract | 4.0 - 7.5 | 5.6 ± 0.2 (Skin-Neutral) | ISO 3071 pH Electrode |
| Heavy Metals (Extractable Pb, Cd) | Pb < 0.2 mg/kg, Cd < 0.1 mg/kg | Not Detected | ICP-MS Acid Digestion |
| Phthalate Plasticizers (DEHP, DBP) | Sum < 0.1% (1,000 ppm) | Not Detected (< 10 ppm) | GC-MS Solvent Extraction |
| Chlorinated Phenols (PCP, TeCP) | < 0.05 mg/kg | Not Detected | GC-ECD Extraction |
2. Zero Synthetic Fragrance, Lotion, & Chlorine Guarantee
Unlike commercial supermarket brands that inject synthetic perfumes or mineral oil lotions to mask odors, Baron Hygiene diapers are formulated fragrance-free. Superabsorbent polymers incorporate natural odor-locking acrylic matrix technology, while wood pulp cores are processed via Totally Chlorine Free (TCF) or Elemental Chlorine Free (ECF) bleaching that eliminates carcinogenic dioxin by-products.
