For formulators across various industries, understanding the chemical properties and functional applications of ingredients is paramount. Butylparaben (CAS 94-26-8) is a well-established preservative that finds widespread use in cosmetics, pharmaceuticals, and food. This article provides a comprehensive overview of Butylparaben, detailing its properties, key applications, and crucial safety considerations for formulators.

Butylparaben, chemically known as butyl 4-hydroxybenzoate, is an ester of 4-hydroxybenzoic acid. It typically presents as a white, odorless, crystalline powder. Its molecular formula is C11H14O3, with a molar mass of 194.23 g/mol. While sparingly soluble in water, it exhibits good solubility in organic solvents like acetone, ethanol, and glycerin, which aids its incorporation into diverse formulations. Its melting point is generally between 68-72°C, indicating its solid state at room temperature.

The primary function of Butylparaben is as an antimicrobial preservative. It is highly effective at low concentrations against a broad spectrum of microorganisms, notably inhibiting the growth of yeasts and molds, and to some extent bacteria. This makes it an invaluable component for extending the shelf life and ensuring the microbiological safety of products in several key sectors:

  • Cosmetics: Used in a wide array of personal care products including lotions, creams, makeup (eyeshadow, lipstick), shampoos, and sunscreens.
  • Pharmaceuticals: Employed as an excipient in liquid formulations, particularly suspensions and emulsions, to prevent microbial contamination.
  • Food: Utilized as a food additive, functioning as an antiseptic and bactericide to preserve food products.

Formulators must be aware of the safety profile and regulatory landscape surrounding Butylparaben. While parabens have been subject to debate, regulatory bodies such as the Scientific Committee on Consumer Safety (SCCS) in Europe and the US Food and Drug Administration (FDA) have reviewed their safety. Current regulations permit the use of Butylparaben within specific concentration limits, based on extensive toxicological data. When seeking to 'buy Butylparaben', formulators should consult current regulations for their specific application and region.

As a 'Butylparaben manufacturer' and supplier, we emphasize the importance of purity and compliance. When you 'purchase Butylparaben', ensure that the material meets the required industry standards (e.g., USP, EP for pharmaceuticals; food grade for food applications). Understanding the 'Butylparaben price' in relation to these quality metrics is crucial for making an informed procurement decision.

In conclusion, Butylparaben is a versatile and effective preservative with well-defined applications in cosmetics, pharmaceuticals, and food. Its chemical properties make it a valuable tool for formulators seeking to ensure product stability and safety. For those looking to 'buy Butylparaben', partnering with a trusted 'Butylparaben supplier' who prioritizes quality, regulatory adherence, and transparent pricing is essential for successful product development.
