Product Introduction:

Methylparaben, also known as methylparaben or methylparaben, is an organic substance with the chemical formula C8H8O3, which is a white crystalline powder or colorless crystals. It is easily soluble in alcohol, ether and acetone and practically insoluble in water. The boiling point is 270-280 ° C.

Due to its phenolic hydroxyl structure, it has stronger antibacterial properties than benzoic acid and sorbic acid.

The mechanism of action of methylparaben is to destroy the cell membrane of microorganisms, denature intracellular proteins, and inhibit the activity of respiratory and electron transport enzymes in microbial cells.

Methylparaben powder is mainly used as a bactericidal preservative and feed preservative for organic synthesis, foods, cosmetics and pharmaceuticals.

Product function:

  • Methylparaben powder can be used as a cosmetic preservative. It is a phenolic preservative and is effective against various molds, yeasts and bacteria, but methylparaben has low bactericidal activity and is usually mixed with ethylparaben, and has excellent additive and synergistic effects.
  • The antiseptic activity of methylparaben powder is related to the pH value of the solution. At a pH value of 7, its activity is 2/3 of its original activity, and at a pH value of 8.5 it is reduced to half its original activity. activity. It binds to high molecular weight compounds such as methylcellulose and gelatin protein and loses its antiseptic effect.
  • In the pharmaceutical industry, methylparaben powder can be used not only as an antiseptic and fungicide for pharmaceuticals, but also as an anticorrosive additive for organic synthesis, foods, spices and films.
  • Similar products manufactured by similar manufacturing methods are the disinfectants and preservatives ethylparaben (paraben B) and propylparaben (paraben C).
  • The product is irritating to the skin.
  • Methylparaben has a wide-spectrum antibacterial effect, can suppress gram-negative and gram-positive bacteria, and has a strong inhibitory effect on yeast and mold. It has a lower concentration and a wider spectrum than conventional preservatives (such as sodium benzoate). Efficient, safe, economical and long-lasting.
  • Methylparaben powder is widely used in the storage of cosmetics, pharmaceuticals, foods and other industrial products.
  • Compatible with various ingredients contained in cosmetics.

Mechanism of Action of Methylparaben

Methylparaben has a vast array of antibacterial results on mold and mildew, yeast and also bacteria, and has the greatest effect on mold and mildew and also yeast, but has inadequate result on microorganisms, particularly Gram-negative bacilli and also lactic acid bacteria.

The system of activity of Methylparaben is to hinder the task of breathing enzymes and also electron transfer enzymes of microbial cells as well as destroy the cell membrane structure of microorganisms, thus protecting against the growth of yeasts, bacteria and also mold and mildews.

The larger the hydrocarbon chain of Methylparaben, the stronger the lipophilicity, and the greater the effect. At the same time, the greater the adsorption capacity of parabens, the greater the effect on the development of bacteria.
