Crotonic acid

Crotonic acid

trans-2-Butenoic Acid; (E)-But-2-enoic Acid; Crotonic Acid, trans-; 2-Butenoic Acid

CAS 107-93-7

Chemical Formula C₄H₆O₂

Molecular Weight 86.09 g/mol

Crotonic acid is an unsaturated carboxylic acid and an organic compound with a double bond in its structure, giving it distinctive chemical reactivity. It is typically manufactured by the oxidation of crotonaldehyde or via catalytic processes involving butadiene. Crotonic acid’s trans isomer (the most stable form) is used as a precursor in polymer production, especially in specialty plastics and resins.

Industrial Uses

1. Food & Beverage

  • Acidulant: Crotonic acid can be used to control pH levels in certain food products, though it is not widely used in the industry as a preservative or additive like formic acid.
  • Packaging Material Additive: Though Crotonic acid is not a direct food additive, its derivatives are used in the development of food-grade packaging materials. These materials help in improving barrier properties, ensuring better preservation of food items.

2. Pharmaceuticals

  • Intermediate in Drug Synthesis: Crotonic acid acts as an intermediate in the synthesis of various pharmaceutical compounds, including the production of certain polymer-based drug delivery systems.
  • Drug Stabilizer: Crotonic acid derivatives may be used in drug formulations to enhance the stability of active ingredients.

3. Personal Care

  • Skin Care: Crotonic acid-based materials may be included in certain skincare products as emulsifiers or stabilizers, improving the texture and consistency of creams and lotions.
  • pH Adjuster: It can serve as a pH modifier in cosmetic formulations to balance the acidity levels, enhancing the stability of the product.

4.Agrochemicals

  • Agrochemical Additive: While Crotonic acid isn’t used directly in agriculture like pesticides, its derivatives may be used in agrochemical formulations, particularly for encapsulating active ingredients to provide a slow-release mechanism.
  • Seed Coatings: Crotonic acid polymers are sometimes applied in seed coating technology, where they assist in controlled water absorption and gradual nutrient release to optimize seed germination and crop yield.

5. Paints & Coatings

  • Water-Based Coatings: Crotonic acid-based copolymers are used in the formulation of water-based coatings, offering good film formation and adhesion while being eco-friendly.
  • UV-Resistant Coatings: The acid helps enhance the UV resistance of certain coating formulations, making it ideal for outdoor applications like exterior paints and protective coatings.
