Science
Mechanism of Action
As an emulsifying agent, PEG-8 Ditallate ensures the stability of oil-in-water or water-in-oil formulations, preventing phase separation and contributing to a desirable texture. Its PEG structure also allows it to bind moisture to the skin through hydrogen bonding with water molecules, thereby reducing transepidermal water loss and increasing hydration. Furthermore, it can act as a solubilizer for sparingly water-soluble components and facilitates the cleansing process by allowing oil and dirt to mix effectively with water for rinsing.

Stability
The PEG component of PEG-8 Ditallate exhibits robust stability, demonstrating resistance to moderately strong acids, alkalis, and various salt solutions. Aqueous solutions maintain stability at room temperatures without hydrolytic degradation. It can be effectively dissolved in warm water, up to 80-90°C, without adverse effects. While generally stable, PEGs are susceptible to oxidative degradation in the presence of air, which can be mitigated by minimizing exposure to elevated temperatures and oxygen, or by incorporating an antioxidant. This ingredient does not hydrolyze or deteriorate upon storage and does not support mold growth.

Safety
Safety Profile
The CIR Expert Panel has deemed PEG diesters, including PEG-8 Ditallate, safe for use in cosmetic products, having removed prior caveats regarding use on damaged skin. It is also approved by the FDA as an indirect food additive. General PEGs display low toxicity upon oral or dermal exposure and minimal ocular irritation. However, it is important to note that certain PEGs, particularly those with Lauric Acid components, may exhibit higher irritation potential; PEG-8 Ditallate is not derived from lauric acid. A potential concern for PEGs is contamination with 1,4-dioxane, a by-product of the ethoxylation process, though this can be effectively managed through stringent purification steps during manufacturing.
