Popular questions
  1. How to apply calcium alginate dressing?

    Cleanse the wound, dry the surrounding skin, then lay or lightly pack the calcium alginate (sheet or rope) to cover/fill the wound without overpacking and cover with an appropriate secondary dressing; it will gel on contact with exudate and lifts out with gentle irrigation at change. Use it on moderate-to-heavily exuding wounds (not dry wounds) and follow product instructions or clinician guidance.

  2. Is calcium alginate and aquacel ag the same thing?

    No. Aquacel Ag is a hydrofiber (sodium carboxymethylcellulose) dressing with ionic silver, while calcium alginate is an alginate fiber dressing without silver unless specified; both gel and absorb exudate, but Aquacel Ag adds antimicrobial action.

  3. Is aquacel ag the same as calcium alginate?

    No—Aquacel Ag is carboxymethylcellulose with silver, whereas calcium alginate is alginate fiber; they’re different materials even though both form a gel and manage exudate. Aquacel Ag provides antimicrobial silver, which standard calcium alginate does not.

  4. What does calcium alginate do for wounds?

    It absorbs moderate-to-heavy exudate and turns into a soft gel that maintains a moist healing environment while helping protect surrounding skin. Its calcium ions can also help support hemostasis in lightly bleeding wounds.

  5. How often to change calcium alginate dressing?

    Typically every 1–3 days, or sooner if the secondary dressing becomes saturated; frequency depends on exudate level and wound condition. Always follow the specific product directions or a clinician’s advice.

  1. Is carrageenan bad for you?

    For most people, food‑grade carrageenan (E407) is considered safe at typical food levels by regulators like EFSA and the FDA; a small number may experience digestive discomfort. Concerns often stem from studies using degraded carrageenan (poligeenan), which is not used in foods.

  2. Carrageenan what is it?

    Carrageenan (E407) is a family of sulfated polysaccharides extracted from red seaweeds, used as a gelling, thickening, and stabilizing agent in foods.

  3. Does carrageenan cause cancer?

    There is no convincing evidence that food‑grade carrageenan causes cancer; studies suggesting risks typically used degraded carrageenan (poligeenan), which is not permitted in foods. Authorities such as EFSA and JECFA consider E407 safe at current use levels.

  4. What is carrageenan used for?

    It thickens and stabilizes foods, helping suspend particles and improve texture in products like chocolate milk, dairy and plant‑based milks, ice cream, yogurt, desserts, and processed meats.

  5. Is carrageenan bad for dogs?

    Food‑grade carrageenan is permitted in pet foods as a stabilizer and is generally regarded as safe at typical levels, though some dogs with sensitive digestion may not tolerate it well. If your dog shows GI upset, choose carrageenan‑free products and consult your veterinarian.
