Mechanism of Action
As an anionic surfactant, Tetrahydroxypropyl Ethylenediamine Dioleate facilitates cleansing, emulsifying, and dispersing within formulations. Its primary action as a chelating agent involves sequestering metal ions like iron, calcium, and magnesium, which helps prevent product degradation and prolong shelf life. Moreover, its parent compound, Tetrahydroxypropyl Ethylenediamine (THPE), actively induces morphological changes and contraction in superficial epidermal keratinocytes, leading to a noticeable skin tensioning effect, which supports anti-aging outcomes such as lifting and wrinkle reduction.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that the parent compound, Tetrahydroxypropyl Ethylenediamine (THPE), is safe for cosmetic use at concentrations up to 0.5%. At these concentrations, THPE is not significantly absorbed through the skin and generally does not provoke irritation or allergic reactions. However, Tetrahydroxypropyl Ethylenediamine Dioleate in its undiluted, liquid form can cause irritation to the skin, eyes, and respiratory system. No specific CIR or SCCS safety assessment for the 'Dioleate' form itself was identified, thus its cosmetic use should adhere to general safety guidelines and appropriate dilution.
