Science
Mechanism of Action
As a higher molecular weight polyethylene glycol (PEG) derivative, PEG-180 BISPOLYLACTIDE functions primarily as a humectant. It draws moisture from the surrounding environment and the deeper layers of the epidermis, holding it on the skin's surface to provide superficial hydration. Its substantial molecular size ensures it remains on the skin's outermost layer without systemic absorption. Additionally, this ingredient acts as a solvent, aiding in the dissolution of oil-based components within water-based formulations, and as an emulsifier, stabilizing the blend of immiscible phases for a cohesive product texture.

The Formula
Formulation
Stability
PEG-180 BISPOLYLACTIDE is an odorless ingredient, exhibiting robust compatibility with a broad array of cosmetic components. It contributes to formulation integrity by acting as a consistency enhancer, binding agent, softening agent, and fixative. Solid PEGs generally demonstrate good skin tolerability and possess inherent microbiological stability, often mitigating the necessity for supplemental preservatives.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of PEG ingredients, including higher molecular weight PEGs like PEG-180, for cosmetic applications, noting their lack of absorption through intact skin. They are characterized as minimally irritating and non-sensitizing. While a rare instance of kidney toxicity was reported in severely burned patients utilizing a PEG-based antimicrobial cream, no systemic toxicity has been observed with application to intact skin. PEG-180 is generally considered non-toxic, non-irritating, and non-comedogenic at recommended usage levels. Prudent practice advises avoiding excessively high concentrations and conducting patch tests before full application. Potential contamination with 1,4-dioxane, a by-product of ethoxylation, is a known industry concern, meticulously managed through rigorous purification steps. This ingredient adheres to the general provisions of the EU Cosmetics Regulation and holds FDA designation for safe use in specific food applications.
