Science
Mechanism of Action
This ingredient functions primarily as an emulsifying agent and surfactant by reducing surface tension between immiscible liquids, allowing them to blend smoothly. The Triethanolamine (TEA) component is responsible for pH adjustment and buffering, which stabilizes the formulation. The rosinate portion, derived from rosin acids, also contributes to these emulsifying and potentially tackifying properties.

The Formula
Formulation
Stability
The Triethanolamine (TEA) component acts as a pH adjuster and buffering agent, crucial for maintaining product stability over time. A critical formulation consideration is the absolute avoidance of co-formulating with N-nitrosating agents to prevent the formation of carcinogenic nitrosamines.
Conflicts
- N-nitrosating agents (e.g., 2-Bromo-2-Nitropropane-1,3-Diol, 5-Bromo-5-Nitro-1,3-Dioxane, sodium nitrate) due to the potential formation of carcinogenic nitrosamines.
Safety
Safety Profile
While there's no specific CIR report for TEA-ROSINATE, the CIR Expert Panel has evaluated Triethanolamine (TEA) and related compounds. They are considered safe for rinse-off cosmetic formulations and for leave-on products at concentrations not exceeding 5%, provided the final product is non-irritating. A paramount restriction, also emphasized by the SCCS in the EU, is to strictly avoid co-formulation with N-nitrosating agents to prevent the formation of carcinogenic nitrosamines.

Verdict
While effective as an emulsifier and pH adjuster, TEA-ROSINATE's use is critically restricted by the imperative to prevent carcinogenic nitrosamine formation, demanding rigorous formulation control.
