DIMETHYL TALLOWAMINE.

Questionable CAS 68814-69-7 / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

DIMETHYL TALLOWAMINE primarily functions as a skin conditioning emollient, contributing to moisture retention by forming a protective surface barrier. It also acts as a surfactant and emulsifying agent, facilitating the stable blending of disparate phases in cosmetic formulations.

Summary

Antistatic Hair Conditioning Emollient Surfactant Emulsifying

Science

Mechanism of Action

DIMETHYL TALLOWAMINE operates as a multifunctional agent, offering antistatic properties, hair conditioning, skin conditioning, and emulsifying capabilities. On the skin, it likely functions as an emollient by establishing a hydrophobic barrier, which helps to reduce transepidermal water loss. As a surfactant, it lowers the surface tension between different phases (e.g., oil and water), allowing them to mix and form stable emulsions.

Stability

No specific optimal pH range for the stability of DIMETHYL TALLOWAMINE has been reported. However, a related compound, Tallow Amine, exhibits a highly alkaline pH of 11-12 in a 1% solution. This suggests that DIMETHYL TALLOWAMINE would likely be stable under alkaline conditions.

Conflicts

  • Potentially reactive with acidic ingredients due to its indicated highly alkaline nature.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

A direct, stand-alone CIR (Cosmetic Ingredient Review) safety assessment for DIMETHYL TALLOWAMINE (CAS 68814-69-7) is not available. Reviews of structurally related ingredient groups, such as 'PEGs tallow amine' and 'Fatty acid amidopropyl dimethylamines', provide some contextual data, with some deemed safe when formulated to be non-irritating or non-sensitizing. However, concentrated polyethoxylated tallow amine (POE-T), a related compound, is described as very irritating to skin, corrosive to eyes, and sensitizing, though these effects are noted to diminish upon dilution. 'Tallow amine' (a primary amine) has also been noted to irritate skin upon contact.

Our Assessment

Verdict

Questionable

While DIMETHYL TALLOWAMINE offers emollient and emulsifying properties, its direct safety profile remains largely unreviewed by the CIR, and strong cautionary data exists for structurally related compounds regarding irritation and sensitization, necessitating extreme caution and further research for cosmetic application.
