LYKKEH uses a family of plant-derived biopolymers — not a single material. The core stack includes Bio-HDPE (Braskem I'm Green™, sugarcane-derived), PLA (polylactic acid, corn/sugarcane fermentation), PHA/PHBV (compostable, heat and impact resistant), and PBS (flexible, film-grade). Each polymer is selected by application — not substituted from a plastic default.
Natural fibre reinforcement — Hemp, Jute, Bamboo, Rice Husk, and Bagasse — is fused into the polymer matrix. This adds structural strength, surface texture, and natural aesthetics while reducing total polymer load per unit. The result: materials that are strong, safe, and naturally circular. No petrochemical precursors. No endocrine-active additives.
Development partnerLYKKEH Biopolymer Compound v1.0 was developed in partnership with CSIR-IICT (Central Institute of Chemical Technology). Material validation, compound qualification, and R&D are ongoing. Test data published quarterly.
Exact compound formulation available under NDA for institutional enquiries. Full ingredient disclosure available to all parents on request.
PLA-based compound. Used for all primary toy structures — rings, sorter shapes, stacker posts. Biodegrades in industrial composting within 18 months. No petroleum-derived plasticisers.
Used for sensory elements that require flexibility — grips, tactile rings, teethable surfaces. Sourced from certified natural rubber plantations. Nitrosamine-free processing.
All colour in LYKKEH products comes from iron-oxide series mineral pigments. No AZO dyes. No solvent-based coatings. No surface finishing. Colour is formulated into the compound — not applied on top.
Before a new raw material enters production, it undergoes full toxicological screening at our development partner lab. This includes EN 71-3 migration testing, carcinogen screen, and sensitiser screen. No untested materials enter the production line.
Every production batch is tested against our internal specification sheet before being released. This includes dimensional inspection, sharp-edge audit, part-minimum-size check, and drop test at 1.2m onto a hardwood surface.
We send one sample from every production batch to SGS India — an independent third-party testing laboratory. SGS runs the full EN 71-1 (mechanical and physical safety), EN 71-2 (flammability), and EN 71-3 (migration of certain elements) test suite.
All LYKKEH products are submitted for BIS IS 9873 certification — the mandatory Indian toy safety standard. The BIS audit includes factory inspection, product testing, and ongoing surveillance. Certificate numbers are printed on every product and available online.
India's mandatory toy safety standard. Covers mechanical and physical properties, flammability, specific element migration, and electrical properties. Mandatory for all toys sold in India.
European toy safety standard, tested by SGS India as a benchmark reference. LYKKEH products are designed to meet EN 71 requirements even where not strictly required by Indian regulations.
The US Consumer Product Safety Improvement Act standard for toy safety. LYKKEH products are designed to meet ASTM F963 from day one — enabling global market access without a material redesign.
ISO standard for aerobic biodegradability of plastic materials under controlled composting conditions. LYKKEH Biopolymer Compound tested to show 90%+ biodegradation within 180 days under industrial composting.
BPA was banned. It was replaced with BPS and TPP — compounds with near-identical endocrine-disrupting effects. Harvard Medical School found that 41% of 46 tested "BPA-free" compounds disrupted reproductive biology equal to or worse than BPA itself.
Consumer Reports 2024: phthalates found in 84 of 85 foods tested — not because phthalates were added to food, but because they migrate from the plastic packaging and processing equipment that touches it. The same mechanism applies to toys that infants mouth.
41% of 46 tested "BPA-free" compounds disrupted reproductive biology equal to or worse than BPA.
Phthalates detected in 84 of 85 foods tested — migrating from plastic packaging and equipment.
Infants face 15× higher microplastic exposure than adults. The primary vector: mouthing of plastic objects.
The LYKKEH position
Bioplastics are not an upgrade. They are an exit from a fundamentally compromised material system. Our polymers carry zero bisphenol compounds — not as a marketing claim, but as a structural reality. Nothing to substitute away from. Derived from microbial fermentation of plant sugars. No petrochemical precursors, no endocrine-active additives, no regrettable substitutions possible.
We maintain an internal prohibited substance list that exceeds the regulatory minimum. If a substance appears here, it will never appear in a LYKKEH product, regardless of permitted limit levels.
