Popular questions
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.
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.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
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.
What is magnesium aluminum silicate?
A refined clay mineral of magnesium, aluminum and silicate layers used mainly as a thickener/stabilizer and anti‑caking agent, similar in function to the magnesium silicates covered by E553 (e.g., talc/magnesium silicate).
Is magnesium aluminum silicate safe?
Yes—when of food/cosmetic grade and used as authorized, it’s considered safe; it is insoluble, minimally absorbed, and specifications require it to be asbestos‑free and low in heavy metals.
Does magnesium aluminum silicate cause cancer?
There’s no evidence it causes cancer when asbestos‑free and used as intended; cancer concerns mainly involve inhalation of asbestos‑contaminated talc, not food/cosmetic‑grade materials.
Is magnesium aluminum silicate safe for skin?
Yes—cosmetic safety reviews consider it safe as used; it largely sits on the skin with minimal absorption, though avoiding inhalation of powders is advisable.
Is magnesium silicate harmful?
Food‑grade magnesium silicate (E553) is generally considered safe at permitted levels and is poorly absorbed; the main risks relate to inhaling fine talc dust or using non‑food‑grade/asbestos‑contaminated material.
