Octocrylene

What is Octocrylene?

Molecular Formula (Octocrylene): C₂₄H₂₇NO₂

Molecular Weight: 361.485 g/mol

Chemical Name: 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate

CAS Number: 6197-30-4

It is an ester derivative chemical. It is a light yellow, viscous liquid. It is an organic compound used in the manufacturing of sunscreens and cosmetic products. As it is a flammable substance, standard working conditions must be followed.

Other Names Include:

• Octocrilene
• 2-Propenoic acid, 2-cyano-3,3-diphenyl-, 2-ethylhexyl ester
• UV Absorber-3
• 2-Ethylhexyl 2-cyano-3,3-diphenyl-2-propenoate
• 2-ethylhexyl 2-cyano-3,3-diphenyl prop-2-enoate
• Octocrilen
• Octyl 2-cyano-3,3-diphenylacrylate
• 2-ETHYLHEXYL 2-CYANO-3,3-DIPHENYL-PROP-2-ENOATE

What are its Physical and Chemical Properties?

It is a chemical in liquid form. It is a chemical compound insoluble in water. It is a stable substance.

It is an acrylate ester derivative. Esters generally react with acids to release heat, along with alcohols and acids.

Octocrylene can cause a very strong exothermic reaction with strong oxidizing acids, igniting the reaction products.

Heat is also generated by the interaction of esters with caustic solutions.

Due to its potential to harm coral reefs, the use of sunscreens, sprays, etc., produced with this chemical has been banned in some countries. Consequently, the use of alternative raw materials that form UV filters has increased.

Density: 1.05 g/cm³

Melting Point: -10 °C

Boiling Point: 216-218 °C

Solubility: Insoluble in water; soluble in oil and organic solvents.

Applications of Octocrylene

• It is used as a UV stabilizer in the manufacturing of unplasticized Polyvinyl Chloride (PVC), some polyethylene terephthalate (PET) polymers, and copolymers.
• It is used in the manufacturing of some food and drug contact plastics.
• It is used in the manufacturing of some cosmetic products, sunscreens, and sun sprays.
• It is used in the industry for manufacturing fragrances. It acts as a fragrance in some industrially produced substances.
• It is used in the manufacturing of personal care products.

What Factors Affect its Price?

The price of Octocrylene increases as its application areas expand. The price has increased approximately 5-fold over a long period because its use has become very widespread.

The price of this chemical shows a radical increase during the summer months. This is because the production of sunscreens and lotions increases during this time. Therefore, the price of the raw material used also increases.

Another factor affecting the price of Octocrylene is the distance of the using company from the production area. The farther from the production area, the higher the price.
