Popular questions
  1. Is benzoic acid soluble in water?

    Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.

  2. Is benzoic acid polar?

    It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.

  3. Is benzoic acid a strong acid?

    No—it's a weak acid, with a pKa of about 4.2.

  4. What is the melting point of benzoic acid?

    About 122–123 °C (251–253 °F).

  5. Is benzoic acid bad for you?

    At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.

  1. Is propylene glycol alginate bad for you?

    No—propylene glycol alginate (E405) is approved in the EU and US and is generally considered safe at permitted levels; most people tolerate it well, though very high intakes may cause mild digestive upset in some individuals.

  2. What is propylene glycol alginate made from?

    It’s made by reacting alginic acid extracted from brown seaweed (kelp) with propylene glycol. Some remaining acid groups may be neutralized with alkali (e.g., sodium).

  3. How do they make propylene glycol alginate?

    Manufacturers extract alginic acid from brown seaweed, purify it, then partially esterify it with propylene glycol under controlled conditions. The material is then neutralized as needed, dried, and milled into a powder.

  4. How is propylene glycol alginate made?

    By partially esterifying seaweed-derived alginic acid with propylene glycol, leaving some carboxyl groups free or neutralized with alkali, then drying the product. This process yields an emulsifier, stabilizer, and thickener used in foods.

  5. How to fix e405 fuel comms error?

    That appears to be a device/vehicle fault code unrelated to the food additive E405 (propylene glycol alginate); consult your equipment manual or the manufacturer’s support for troubleshooting.
