What is Apa Itu Methylparaben?

Apa Itu Methylparaben, additionally referred to as parahydroxybenzoin ester, paraben (NipaEster.Paraben).Apa Itu Methylparaben, ethyl, propyl, isopropyl, butyl, isobutyl, etc are made use of as fungicides and chemicals. Representative is Apa Itu Methylparaben (paraben A. Nipagin A. Ethylparaben. Ethylparasept). This product is anemic penalty crystal or white crystalline powder, with unique fragrance, somewhat bitter preference, shedding numb. Melting point: 116 ~ 118 ℃, Boiling point: 297 ~ 298 ℃ (decay).LD505g/kg (mice, oral), no uncommon blood photo and pathological adjustments of interior organs were found in the subacute poisoning examination. Concentration below 5% is not annoying to human skin. ADI is 0 to 10 mg/kg. Among the Apa Itu Methylparaben, butyl ester has the most affordable poisoning and also the greatest disinfectant and antiseptic result, but has bad water solubility as well as is typically utilized in mix with various other esters.

Apa Itu Methylparaben Uses

  1. Apa Itu Methylparaben is mainly utilized as an antiseptic chemical in organic synthesis, food, cosmetics, medicine, as well as additionally as a feed preservative.
  2. Apa Itu Methylparaben is used as a preservative and additionally in medication as well as natural synthesis.
  3. Apa Itu Methylparaben is utilized as antifungal representative in food, cosmetics and medication.
  4. Apa Itu Methylparaben is made use of in the pharmaceutical sector as a preservative and also bactericide for pharmaceuticals, and also is additionally made use of in natural synthesis and also as a preservative additive for food, spices, films, and so on. Similar products, ethyl parahydroxybenzoate (B paraben) and also propyl parahydroxybenzoate (C paraben) generated by comparable manufacturing approaches, are likewise anti-bacterials and bactericides. This product is annoying to the skin.
  5. Apa Itu Methylparaben is used in antiseptic fungicides. Insect cell society qualities are used to examine the biosynthesis of steroid hormonal agents such as testerone.

Safety of Apa Itu Methylparaben

Many countries and regions in the world allow sodium parabens to be used in food, and consider them generally safe, and their maximum addition amount converted into Apa Itu Methylparaben(the same below) can reach 0.1%, when When several esters and sodium are used in combination, the total amount should not exceed 0.1%. Heptyl p-hydroxybenzoate is generally selectively used in some foods. In beer, the maximum dosage is 12mg/kg, and in some carbon dioxide-free soft drinks and fruit alcoholic beverages, the maximum dosage can reach 20mg /kg. Developed countries such as the United States, the United Kingdom, and Japan allow sodium parabens to be used in food and are considered safe.
Toxicity comparison of Apa Itu Methylparaben (sodium), benzoic acid (sodium) and sorbic acid (potassium), it can be seen that these three preservatives have the highest apparent safety of potassium sorbate, potassium sorbate 3 p-hydroxy Sodium Benzoate 3 Sodium Benzoate. However, in actual use, the amount of sodium Apa Itu Methylparaben
added is much less than that of sodium benzoate and potassium sorbate. Eating the same and the same amount of food, the amount of sodium paraben ingested in the human body is also Much lower than sodium benzoate and potassium sorbate. Therefore, the actual use of safety sodium paraben is the best, sodium paraben 3 potassium sorbate 3 sodium benzoate. In fact, sodium benzoate is restricted as a food additive in many countries, and my country also stipulates that sodium benzoate is not allowed in grade A green food. Due to the small amount of sodium paraben added, the use cost of sodium paraben is much lower than that of potassium sorbate, and it is close to sodium benzoate. Therefore, sodium Apa Itu Methylparaben is a kind of low-toxicity, high-efficiency, broad-spectrum food preservative worthy of development, and it is the best product to gradually replace sodium benzoate in line with international standards.

Antibacterial activity of Apa Itu Methylparaben

Apa Itu Methylparaben have been used as food and pharmaceutical preservatives since the 1930s. Due to poor water solubility, the application of Apa Itu Methylparaben in the food industry is limited. Utilizing the acidity of the para-phenolic group of Apa Itu Methylparaben, the produced sodium parabens is easily soluble in water, which is convenient for popularization and application in the food industry. It is worth pointing out that it has the same effect as sodium benzoate and potassium sorbate. , The production of sodium paraben is to improve the water solubility, and the antibacterial effect is still molecular paraben. On a dry basis, 1g sodium Apa Itu Methylparaben, sodium ethylparaben, sodium propylparaben and sodium butylparaben are equivalent to 0.873g methylparaben, 0.883 g ethyl paraben, 0.891 g propyl paraben, and 0.898 g butyl paraben.

The mechanism of action of sodium paraben is to destroy the cell membrane of microorganisms, denature the proteins in the cells, and inhibit the activity of the respiratory enzymes and electron transfer enzymes of the cells. The antibacterial activity of sodium paraben mainly works in the molecular state. Because the carboxyl group in the molecule has been esterified and is no longer ionized, the ionization constant of the para-phenol group is very small. The bacteriostatic effect has good effect in a wide pH range. The antibacterial mechanism of sodium benzoate and potassium sorbate lies in the inhibition of various enzymes in microbial cells. Only molecular benzoic acid and sorbic acid can penetrate the cell wall and enter the cells of microorganisms to exert antibacterial activity. Strictly speaking, these three types of preservatives are organic weak acids, which can be ionized in aqueous solution, and exist in molecular state and ionic state in solution.

Apa Itu Methylparaben Use Limit

FAO/WHO (1984 ); jam, jelly, 1000mg/kg (solitary or integrated with benzoates, sorbic acid as well as potassium sorbate). EEC (1990, mg/kg): Approved for pigment solutions, flavorful syrups, coffee essences, icy beverages, fruit juices, dextrose and also soft drinks, pickled fish, salads, sauces, snack foods, focused soups, and so on.
