Science
Mechanism of Action
This ingredient functions by creating a fine, protective film on the skin's surface. This film acts as a barrier, effectively preventing transepidermal water loss and shielding the skin from dehydration. As a result, it helps to restore the skin's natural suppleness, refines its texture, and imparts a perceptibly smooth, silky sensation.

Key findings
- 01 While specific clinical efficacy studies for PPG-120 Butyl Ether were not identified, related ingredients within the PPG Butyl Ether group, such as PPG BE800 (with an average molecular weight of 800) and PPG-40 Butyl Ether, have demonstrated non-irritating and non-sensitizing properties in human patch tests. These studies, involving 200 and 112 subjects respectively, primarily evaluated safety rather than specific efficacy outcomes like wrinkle reduction or hydration levels. The absence of specific efficacy data for PPG-120 Butyl Ether warrants further targeted investigation.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed PPG Butyl Ethers, as a class, safe for cosmetic use when formulated to be non-irritating. Toxicity generally diminishes with increasing molecular weight; thus, PPG-120 Butyl Ether, being a higher molecular weight compound, is anticipated to have a lower potential for toxicity. Clinical tests on related PPG Butyl Ethers (PPG BE800, PPG-40 Butyl Ether) showed non-irritant and non-sensitizing results in human subjects. However, formulators should be cognizant of potential residual impurities, such as ethylene oxide, propylene oxide, and 1,4-dioxane, and their capacity as penetration enhancers. This ingredient is compliant with general provisions of the EU Cosmetics Regulation.
