Popular questions
  1. When is cmc coming back?

    CMC (E466) hasn’t been withdrawn; it remains approved in the EU and US and is widely produced, so any restock timing depends on the specific retailer or supplier.

  2. When will cmc return?

    There’s been no general ban or recall of sodium carboxymethyl cellulose; if you’re seeing a shortage, only the manufacturer or seller can give a return date.

  3. When will cmc be back?

    CMC is still authorized and manufactured—availability issues are local or product-specific, so contact the brand or distributor for timing.

  4. How long is cmc out?

    It isn’t out globally; regulatory approval and production continue, and any gaps are due to individual supply chains.

  5. Is cmc coming back?

    Yes—CMC (E466) remains permitted and in use; if a particular product removed it, only that brand can say whether they’ll add it back.

  1. Is hydroxypropyl cellulose safe?

    Yes—E463 (hydroxypropyl cellulose) is authorized for use as a food thickener/stabilizer and has no numerical ADI from major authorities (e.g., JECFA/EFSA), indicating low toxicity. It is poorly absorbed, though very high intakes may cause mild gastrointestinal effects.

  2. What is hydroxypropyl methyl cellulose?

    Hydroxypropyl methyl cellulose (HPMC, E464) is a related modified cellulose used as a thickener and stabilizer; unlike E463 (hydroxypropyl cellulose), it also contains methyl groups, which slightly alter its gelation and viscosity behavior.

  3. How do i update my usb driver using windows 7 home premium so i can use my sony walkman nwz-e463?

    That request isn’t about the food additive E463; here E463 refers to hydroxypropyl cellulose, not a Sony Walkman model. For driver updates, please consult Microsoft/Sony support resources.

  4. How is hydroxypropyl cellulose made?

    It is produced by reacting purified cellulose with propylene oxide under alkaline conditions to introduce hydroxypropyl groups, then neutralized, washed, and dried. The degree of substitution and molecular weight are controlled to achieve specific viscosity grades.

  5. How much hydroxypropyl cellulose to use in a formula to make it gel?

    In food formulations, about 0.2–2% w/w gives noticeable thickening, while roughly 1–3% can yield a gel‑like, spoonable texture depending on grade and other ingredients. HPC forms viscous solutions rather than a firm elastic gel, so exact levels require small-scale trials.
