Market
Bleached shellac (INS 904) is a specialty glazing/surface-finishing additive used in Brazil primarily via imports for confectionery and other coated foods, and for pharmaceutical/dietary-supplement tablet/capsule coatings. Brazil’s use context is driven by ANVISA’s food-category authorizations and Mercosur technical regulations that reference INS-based additive listings. Where permitted, shellac is also used for surface treatment of fresh produce; ANVISA regulatory updates and category-specific limits (often quantum satis) determine practical market access. The market is therefore compliance-led, with demand linked to downstream manufacturers’ coating and appearance/handling requirements.

Specification
Physical Attributes- Bleached shellac is described as an off-white to tan, amorphous, granular resin; wax-free bleached shellac as a light yellow, amorphous, granular resin
- Generally insoluble in water and soluble (slowly) in alcohol, supporting use as solvent-based glazing/coating systems
Compositional Metrics- Acid value is referenced in some specifications/compendia sources as a quality parameter (e.g., values reported in the literature and databases for shellac)
Grades- Bleached shellac
- Wax-free bleached shellac (dewaxed grade)
Packaging- Typically supplied as granular resin/flakes/powder for industrial use; moisture-barrier packaging is commonly used to protect quality during storage and distribution
Supply Chain
Value Chain- Import (resin) → dry storage → quality release against specification → dissolution/compounding into coating system (as applicable) → application as glazing/surface-finishing in food or pharmaceutical production → finished goods distribution
Temperature- Generally handled as a shelf-stable dry resin; protect from heat and humidity during storage in Brazil to reduce softening/caking risk

Risks
Regulatory Compliance HighIn Brazil, shellac (INS 904) use is category-specific under ANVISA/Mercosur-aligned additive lists; if the intended application is not authorized (or a consultation outcome is assumed but not yet enacted), products using the coating can be non-compliant, risking enforcement actions, recalls, or blocked commercialization.Validate the exact ANVISA authorization for the intended food category (and any current updates), document the legal basis, and align labeling/technical files before import and production runs.
Food Safety MediumNon-conformity to identity/purity specifications (e.g., impurities from processing/bleaching or inconsistent grade declaration between bleached vs. wax-free bleached shellac) can lead to customer rejection or regulatory non-compliance in Brazil.Require CoA to JECFA specifications for each lot, verify grade identity (bleached vs. wax-free bleached), and implement incoming QC and supplier qualification.
Market Access MediumBecause shellac is insect-derived, misalignment with vegan/vegetarian positioning or unverified religious-dietary claims (e.g., halal/kosher) can create reputational and compliance risk in Brazil’s retail and supplement/pharma channels.Disclose ingredient origin transparently in internal compliance files, avoid vegan claims, and obtain channel-specific halal/kosher certifications when required.
Sustainability- Origin-country biodiversity and host-tree stewardship considerations for lac cultivation/harvesting (supply chain is predominantly outside Brazil)
- Chemical use and wastewater management expectations at bleaching/processing stages in the upstream supply chain
Labor & Social- Insect-derived ingredient (lac insect) can trigger ethical/consumer scrutiny for vegan positioning; ensure marketing claims in Brazil do not misrepresent the ingredient’s origin
FAQ
Qual é a função do shellac (INS 904) no mercado brasileiro?O shellac (INS 904) é usado principalmente como agente glaceante/recobrimento (glazing/surface-finishing) para dar brilho e proteção superficial em certos alimentos e, fora do uso alimentar direto, como material de revestimento em comprimidos e cápsulas. No Brasil, o uso em alimentos depende das autorizações por categoria definidas pela Anvisa e referências do Mercosul, e também existe referência de uso em categorias como frutas com tratamento de superfície.
O uso de shellac é automaticamente permitido em qualquer alimento no Brasil?Não. No Brasil, a lógica regulatória de aditivos é por categoria de alimento e função tecnológica. Mesmo quando o shellac (INS 904) aparece em listas técnicas (como no âmbito Mercosul) e em anexos da Anvisa para certas categorias, o uso deve ser validado para a categoria específica do produto final e respeitar as condições aplicáveis (frequentemente quantum satis).
Shellac (INS 904) é compatível com alegações veganas?Não. O shellac é obtido a partir de secreções de insetos (lac insect), então não é compatível com alegações veganas. Para canais que exigem halal ou kosher, a aceitação pode ser condicional e deve ser confirmada com o certificador e o cliente-alvo.
