PEG-2 LAURAMINE.

Insufficient Data CAS 31017-83-1 / ANTISTATIC, SURFACTANT - FOAM BOOSTING

PEG-2 Lauramine is an ethoxylated fatty amine that functions as a surfactant. It effectively aids in forming stable emulsions and enhances cleansing by reducing surface tension, allowing water to mix with oils and dirt for easy removal. This ingredient also acts as a foam booster in formulations.

Science

Mechanism of Action

As an ethoxylated fatty amine, PEG-2 Lauramine operates as a surfactant. Its primary mechanism involves lowering the surface tension between different phases, which facilitates the formation of stable emulsions. Additionally, it enhances cleansing by enabling water to effectively mix with and lift oily residues and dirt from the skin or hair, and contributes to foam generation.

Stability

While generally stable, PEG-2 Lauramine solutions may exhibit reduced pH and increased ionic strength over time due to aging processes. These effects are accelerated by exposure to warm temperatures, light, and oxygen. To maintain stability, storage at frozen or refrigerated temperatures, oxygen purging, and light protection are recommended. Its low ethoxylation number (PEG-2) suggests poor resistance to alkaline conditions.

Conflicts

  • Alkaline conditions (due to low ethoxylation number)
  • Anionic surfactants (due to low ethoxylation number)

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The CIR Expert Panel, in a 2015 amended assessment, determined that insufficient data exists to establish the safety of PEG-2 Lauramine. They specifically requested information on physical and chemical properties (including nitrosamine impurities), genotoxicity, 28-day dermal toxicity, and dermal sensitization. Concerns arise from an earlier CIR report noting that Lauramine, the base compound, caused severe dermal irritation and necrosis in animal studies. The panel advises that products containing this ingredient must be formulated to prevent irritation and minimize hydroperoxide formation. While the FDA has approved related PEG Dilaurate ingredients for indirect food contact, this approval does not extend to cosmetic use of PEG-2 Lauramine.

Our Assessment

Verdict

Insufficient Data

The safety of PEG-2 Lauramine is currently undetermined by the CIR Expert Panel due to insufficient data, and its base compound has shown severe irritation, leading to a cautious recommendation for its use in precision skincare.
