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 carbomer in skin care?
A synthetic, cross‑linked poly(acrylic acid) polymer used to thicken and gel water-based formulas and to stabilize emulsions, giving gels and lotions a smooth, consistent texture.
Is carbomer safe for skin?
Yes—it's widely used in cosmetics and generally well tolerated; mild, temporary irritation can occur in some people, especially at high concentrations or if the formula isn’t properly neutralized.
What is carbomer used for?
As a food additive (E1210) it serves as a thickener, stabilizer, and film‑forming agent—mainly in food supplement coatings/tablets—and in cosmetics it controls viscosity and stabilizes emulsions.
What is a carbomer?
A family of high‑molecular‑weight, cross‑linked poly(acrylic acid) polymers (also called carboxyvinyl polymers) made synthetically and used primarily as rheology modifiers.
Is carbomer safe?
Within approved uses and levels (e.g., EU E1210 for specific applications), it has a good safety profile; it’s minimally absorbed and generally safe, though large oral amounts may cause GI discomfort.
