What is the difference between "eco-friendly" marketing and actual EN 71-3 certification?

Marketing claims are self-declared. EN 71-3 is an independent lab test — TÜV Rheinland in our case — that measures migration of 19 heavy metals from a cured surface into a saliva-like solution. The certificate has a sample ID, a lab signature, and pass/fail thresholds. You can request ours for every batch.

Can I use LEINOS 290 hardwax oil on a child's wooden toy or chewable spoon?

Yes — 290 carries EN 71-3 and DIN 53160 (saliva resistance). It is fully cured in 7-10 days under Indian conditions. We do recommend the food-contact 280 oil for surfaces specifically intended for direct chewing or food preparation, since it is purpose-tested for LFGB §31 food-contact criteria.

Will the 665 lime paint trigger allergy reactions in sensitive households?

Less likely than synthetic acrylic emulsions, because 665 has no biocides, no solvent residue, no fragrance. The binder is slaked lime (calcium hydroxide), which is mineral. Colour comes from natural earth or mineral oxide pigments. Initial application has a faint mineral smell that fades within 24-48 hours.

Who really feels this in India

Premium parents specifying nurseries in Bangalore and Mumbai — looking past "eco" claims, asking for actual lab numbers.
Households with eczema, asthma, or chemical sensitivity — where VOC and migration data matter more than colour cards.
Architects building schools, pediatric clinics, and play areas — needing EN 71-3 documentation for tender submissions.

How LEINOS answers this

Most "child-safe" paint claims are unfalsifiable marketing. EN 71-3 is the European toy-safety standard — it measures the actual migration of heavy metals from a finished surface into saliva. We test under it, and we publish the certificates. LEINOS 290 hardwax oil (interior wood + furniture), 280 countertop oil (food-contact surfaces), 660 natural resin emulsion paint, and 665 lime paint all meet EN 71-3. The 290 also carries DIN 53160 saliva-resistance certification, which matters specifically for cribs, tables, and toys. Linseed-based formulations have a low VOC envelope (under 30 g/L on most products, verified independently by WESSLING and ihd Dresden). For homes where someone reacts to standard wall paint, mineral lime (665) goes further — no biocides, no preservatives, no solvent residue.
