A self-heating food-pouch project should distinguish the proposed raw chemical from a completed heating system. This calcium oxide is a white CaO powder with a stated 90%-93% purity range. It is an enquiry candidate for material qualification, with the actual grade and system requirements still to be established.
Which material is being requested for pouch development?
The supplied identity is calcium oxide, also called quicklime, with CAS 1305-78-8. Keep that identity and the white-powder form attached to the sample documents. A raw powder description does not identify a complete pouch construction or demonstrate how a finished pack will perform.
What does the 90%-93% assay answer?
The range provides a chemical comparison point for the proposed material. Ask for the actual batch analysis and relevant technical tests before accepting the grade. Purity should not be treated as a heating-output measurement, an activation instruction or evidence of direct food-contact suitability.
Which pouch-system evidence belongs in the enquiry?
Request the intended system specification and the documents needed to review material compatibility. Food-related suitability and grade compliance require their own supporting evidence, separate from the assay. The development team should identify which qualification results must be reviewed before the material is accepted for that system.
A useful sample package therefore connects the confirmed CaO grade, batch documents and intended pouch requirements. It lets the relevant technical reviewers assess a defined material rather than a broad application name. No food-grade approval, direct food-contact claim, heating result or operating recipe follows from this raw-material description alone.
