프로필파라벤 MSDS

• 4-Hydroxybenzoic acid propyl ester

프로필파라벤 화학적 특성, 용도, 생산

• 화학적 성질

  Propylparaben occurs as a white, crystalline, odorless, and tasteless powder.

• 용도

  propylparaben is one of the most frequently used preservatives against bacteria and mold. It has a low sensitizing and low toxicity factor, is reputed to be very safe, and considered to be a noncomedogenic raw material.

• 정의

  ChEBI: The benzoate ester that is the propyl ester of 4-hydroxybenzoic acid. Preservative typically found in many water-based cosmetics, such as creams, lotions, shampoos and bath products. Also used as a food additive.

• 제조 방법

  Produced by esterfying p-hydroxybenzoic acid with n-propanol, using an acid catalyst such as sulfuric acid and an excess of propanol. The materials are heated in a glass-lined reactor under reflux. The acid is then neutralized with caustic soda and the product is crystallized by cooling. The crystallized product is centrifuged, washed, dried under vacuum, milled and blended, all in corrosion-resistant equipment to avoid metallic contamination.

• 생산 방법

  Propylparaben is prepared by the esterification of p-hydroxybenzoic acid with n-propanol.

• 일반 설명

  Colorless crystals or white powder or chunky white solid. Melting point 95-98°C. Odorless or faint aromatic odor. Low toxicity, Tasteless (numbs the tongue). pH: 6.5-7.0 (slightly acidic) in solution.

• 공기와 물의 반응

  Water soluble [Hawley].

• 반응 프로필

  Maximum stability of Propylparaben occurs at a pH of 4 to 5. Incompatible with alkalis and iron salts. Also incompatible with strong oxidizing agents and strong acids .

• 화재위험

  Flash point data for Propylparaben are not available; however, Propylparaben is probably combustible.

• Pharmaceutical Applications

  Propylparaben is widely used as an antimicrobial preservative in cosmetics, food products, and pharmaceutical formulations.
  It may be used alone, in combination with other paraben esters, or with other antimicrobial agents. It is one of the most frequently used preservatives in cosmetics.
  The parabens are effective over a wide pH range and have a broad spectrum of antimicrobial activity, although they are most effective against yeasts and molds.
  Owing to the poor solubility of the parabens, the paraben salts, particularly the sodium salt, are frequently used in formulations. This may cause the pH of poorly buffered formulations to become more alkaline.
  Propylparaben (0.02% w/v) together with methylparaben (0.18% w/v) has been used for the preservation of various parenteral pharmaceutical formulations.

• 색상 색인 번호

  This substance is one of the parabens family. Parabens are esters formed by p-hydroxybenzoic acid and an alcohol. They are largely used as biocides in cosmetics and toiletries, medicaments, or food. They have synergistic power with other biocides. Parabens can induce allergic contact dermatitis, mainly in chronic dermatitis and wounded skin.

• Safety

  Propylparaben and other parabens are widely used as antimicrobial preservatives in cosmetics, food products, and oral and topical pharmaceutical formulations.
  Propylparaben and methylparaben have been used as preservatives in injections and ophthalmic preparations; however, they are now generally regarded as being unsuitable for these types of formulations owing to the irritant potential of the parabens. Systemically, no adverse reactions to parabens have been reported, although they have been associated with hypersensitivity reactions. The WHO has set an estimated acceptable total daily intake for methyl, ethyl, and propyl parabens at up to 10 mg/kg body-weight.
  LD50 (mouse, IP): 0.2 g/kg
  LD50 (mouse, oral): 6.33 g/kg
  LD50 (mouse, SC): 1.65 g/kg

• 저장

  Aqueous propylparaben solutions at pH 3–6 can be sterilized by autoclaving, without decomposition.At pH 3–6, aqueous solutions are stable (less than 10% decomposition) for up to about 4 years at room temperature, while solutions at pH 8 or above are subject to rapid hydrolysis (10% or more after about 60 days at room temperature).

• 비 호환성

  The antimicrobial activity of propylparaben is reduced considerably in the presence of nonionic surfactants as a result of micellization. Absorption of propylparaben by plastics has been reported, with the amount absorbed dependent upon the type of plastic and the vehicle. Magnesium aluminum silicate, magnesium trisilicate, yellow iron oxide, and ultramarine blue have also been reported to absorb propylparaben, thereby reducing preservative efficacy.
  Propylparaben is discolored in the presence of iron and is subject to hydrolysis by weak alkalis and strong acids.

• Regulatory Status

  Propylparaben and methylparaben are affirmed GRAS direct food substances in the USA at levels up to 0.1%. All esters except the benzyl ester are allowed for injection in Japan. In cosmetics, the EU and Brazil allow use of each paraben at 0.4%, but the total of all parabens may not exceed 0.8%. The upper limit in Japan is 1.0%.
  Accepted as a food additive in Europe. Included in the FDA Inactive Ingredients Database (IM, IV, and SC injections; inhalations; ophthalmic preparations; oral capsules, solutions, suspensions, and tablets; otic, rectal, topical, and vaginal preparations).
  Included in parenteral and nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
