HEPTYL METHACRYLATE.

Avoid CAS 5459-37-0 / PERFUMING

Heptyl Methacrylate is a hydrophobic monomer primarily employed in industrial contexts for the production of polymers and copolymers, contributing flexibility and chemical resistance to materials. In cosmetic applications, its function is limited to that of a perfuming agent, providing an aromatic quality.

Summary

Perfuming Agent

Science

Mechanism of Action

As a monomer, Heptyl Methacrylate's primary action involves polymerization in industrial settings. In cosmetic formulations, it imparts an aromatic profile, functioning as a fragrance component. It does not possess beneficial direct skin mechanisms and is noted for its irritant and sensitizing properties upon contact.

Stability

Heptyl Methacrylate should be stored in a cool, well-ventilated area, shielded from ignition sources. It is susceptible to exothermic polymerization when exposed to heat or contaminated with strong acids or bases, necessitating the use of inhibitors to maintain product stability.

  • Strong bases
  • Heat (leading to polymerization)
  • Initiators of polymerization

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel deemed methacrylate ester monomers, including related compounds, safe only when skin contact is rigorously avoided in nail enhancement products, citing their substantial sensitizing potential. Products containing this ingredient require explicit warnings to prevent skin exposure. Heptyl Methacrylate is associated with GHS hazard statements indicating skin irritation (H315), serious eye irritation (H319), and potential respiratory irritation (H335). Historical FDA rulings on related methacrylates, such as liquid methyl methacrylate monomer being classified as a 'poisonous and deleterious substance' for nail preparations, underscore the regulatory caution surrounding skin exposure to this class of compounds.

Our Assessment

Verdict

Avoid

Due to its high irritancy and sensitizing potential requiring strict avoidance of skin contact, Heptyl Methacrylate is unsuitable for precision skincare formulations.
