99% Pure Methylparaben | Cosmetic Food Grade | Bulk Supply

Q1: What is Methyl Paraben, and what is its standard global identifier?

A: Methyl Paraben (also written as Methylparaben, chemical name: Methyl p-Hydroxybenzoate, CAS 99-76-3) is the methyl ester derivative of p-hydroxybenzoic acid. It appears as a white crystalline powder, odorless or almost odorless, and is one of the most widely used broad spectrum preservatives globally.

Q2: What is the antimicrobial spectrum of Methyl Paraben?

A: Methyl Paraben delivers broad spectrum antimicrobial activity: it effectively inhibits the growth of bacteria, yeast and mold, with particularly high efficacy against fungi (yeast and mold). It is widely recognized for its stable and reliable preservative performance.

Q3: What is the recommended usage level of Methyl Paraben in formulations?

A: The standard recommended dosage:

Cosmetics: 0.03% – 0.30% for optimal efficacy

Regulatory limit (EU SCCS): Maximum 0.4% when used alone; maximum 0.8% total parabens when blended with other paraben esters

Food: Maximum 1 mg/g (FDA GRAS standard)

Q4: Is Methyl Paraben compliant with global regulatory standards?

A: Yes, Methyl Paraben has full global regulatory approval:

Pharmaceutical: Compliant with USP, NF, Ph. Eur. pharmacopoeia standards

Cosmetics: EU SCCS approved for use as cosmetic preservative within concentration limits

Food: US FDA GRAS (Generally Recognized As Safe), approved food additive with E number E218, compliant with FCC standards

Q5: Is Methyl Paraben safe for use, and is it carcinogenic?

A: Yes, high-purity Methyl Paraben has an excellent safety profile. Extensive scientific research and over 50 years of global safe use confirm:

It has no carcinogenic potential when used within regulatory concentration limits

It has low sensitization potential and is suitable for most formulation types

All major global regulatory bodies (FDA, EU SCCS, WHO) confirm its safety for approved uses

Q6: Can Methyl Paraben be combined with other preservatives for synergistic effect?

A: Yes, Methyl Paraben has excellent formulation compatibility. It delivers significant synergistic preservative effect when blended with other paraben esters (ethyl paraben, propyl paraben, butyl paraben), expanding antimicrobial spectrum and reducing total required concentration. It also works well with most other cosmetic and food preservatives.

Q7: In which products and industries is Methyl Paraben commonly applied?

A: Methyl Paraben is widely used across 3 major industries:

Cosmetics & personal care: Creams, lotions, serums, makeup, hair care, oral care products

Food & beverage: Syrups, beverages, processed foods, pickled products

Pharmaceutical: Oral liquids, topical preparations, injections, biopharmaceutical formulations

Q8: What are the key quality specifications for premium Methyl Paraben?

A: High-quality cosmetic/food/pharmaceutical grade Methyl Paraben meets the following core specifications:

Purity (HPLC): ≥ 99.0%

Melting point: 125 – 128°C

Loss on drying: ≤ 0.5%

Heavy metals (as Pb): ≤ 10 ppm

Arsenic (As): ≤ 3 ppm

Q9: Is Methyl Paraben stable in formulations?

A: Yes, Methyl Paraben has excellent chemical stability: it is non-volatile, chemically inert, and maintains full preservative efficacy under conventional storage and processing conditions across a wide pH range. It is one of the most stable preservatives available.

Q10: Does Methyl Paraben cause skin irritation or sensitization?

A: High-purity Methyl Paraben has very low sensitization potential when used within recommended concentrations. It is suitable for a wide range of formulations including sensitive skin products, and has a long history of safe use in personal care products.

Q11: Can Methyl Paraben be used as a food preservative?

A: Yes, Methyl Paraben is an approved food preservative globally. It is FDA GRAS, has E number E218, and has over 50 years of safe use history in food and beverage products including syrups, soft drinks, processed foods and pickled products.
