About
What it is and where it shows up.
Methyl cellulose is a chemically modified cellulose in which some hydroxyl groups are replaced with methyl ether groups, yielding a white odourless powder that dissolves in cold water to form viscous gels. It is widely used in food as a thickener, stabiliser, emulsifier, gelling agent, and bulking agent.
Safety summary
The regulatory and scientific consensus.
Both JECFA and EFSA have established an ADI 'not specified' for methyl cellulose, meaning no quantitative daily intake restriction is required. The substance is not absorbed and is excreted largely intact in the faeces, with possible partial fermentation by intestinal microflora. No significant toxicity, genotoxicity, or carcinogenicity has been identified in comprehensive safety evaluations.
Regulatory landscape
What food-safety regulators have decided.
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | Authorised quantum satis as a food additive under Annex II and Annex III of Regulation (EC) No 1333/2008; ADI 'not specified' confirmed in the 2018 EFSA ANS Panel re-evaluation (EFSA Journal 2018;16(1):5047); functional uses include emulsifier, stabiliser, thickener, and gelling agent. Purity criteria defined in Commission Regulation (EU) No 231/2012.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Listed as INS 461 in the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011; permitted at GMP levels in specified food categories as a thickener, stabiliser, and gelling agent.source |
| FDA (Food and Drug Administration) (United States) | Approved | Listed in the FDA Substances Added to Food (EAFUS) inventory; regulated as a direct food additive and GRAS substance; functional uses include thickener and stabiliser under 21 CFR Part 182.source |
Who should approach with care
Whose guidance would steer them away.
Ibs — As a non-absorbed bulking agent and gelling fibre that can be partially fermented by intestinal flora (noted in EFSA 2018 opinion), methyl cellulose may exacerbate bloating, gas, or altered bowel habits in individuals with irritable bowel syndrome at high intake levels.
Ibd — Partial fermentation of methyl cellulose by intestinal microflora (confirmed by EFSA ANS Panel 2018) may increase gas production and gastrointestinal discomfort in individuals with active inflammatory bowel disease.
