DIMETHYL COCAMINE.

Insufficient Data CAS 61788-93-0 / ANTISTATIC, EMULSION STABILISING, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Dimethyl Cocamine is a tertiary fatty amine derived from coconut oil. It primarily functions as a chemical intermediate, essential for the synthesis of various surfactants and conditioning agents, which then impart functional benefits to personal care products.

Science

Mechanism of Action

This ingredient serves as a foundational precursor in industrial chemical processes, leading to the creation of functional derivatives such as amine oxides and quaternary ammonium compounds. These derivatives subsequently modify surface tension, acting as surfactants to facilitate cleansing and emulsification (the stable mixing of oil and water), and function as antistatic agents to reduce electrical charge buildup.

Dusting Analysis

Not commonly dusted

Dimethyl Cocamine's primary role is that of a chemical intermediate, not a direct active ingredient with measurable efficacy on the skin. Consequently, it is not typically 'dusted' or assessed for direct percentage-dependent skin benefits in formulations.

Stability

Dimethyl Cocamine is considered stable and suitable for industrial and formulation processes when handled according to recommendations. In a 1% solution in IPA, the raw material exhibits a neutral to slightly basic pH. Its derived compounds, particularly amine oxides, demonstrate a unique pH-dependent behavior, acting as cationic surfactants under acidic conditions and as nonionic surfactants in neutral or alkaline environments.

  • Nitrosating systems
  • Strong oxidizers
  • Acidic conditions (for raw material storage)

Safety

Safety Profile

CIR Status
Safe as used
Max tested
2.5%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Dimethyl Cocamine, along with related ingredients, is safe as currently utilized in non-coloring hair care products, demonstrating no dermal irritation or sensitization at typical concentrations. In the European Union, its use is permitted in non-rinse-off products at a maximum authorized concentration of 2.5%, with no concentration limit for rinse-off products. All formulations must adhere to stringent purity criteria: a minimum purity of 99%, a maximum secondary amine content of 0.5%, and a maximum nitrosamine content of 50 microg/kg. It is critical that this ingredient is not incorporated into nitrosating systems and that products containing it are stored in nitrite-free containers.

Our Assessment

Verdict

Insufficient Data

Dimethyl Cocamine is a vital chemical intermediate for creating functional derivatives in many cleansing and conditioning products, but direct clinical efficacy data for it as an active skin ingredient is currently unavailable.
