EOP ●
TL;DR. This ingredient is a barrier-repair and skin-conditioning lipid used to support the stratum corneum lipid matrix and reduce transepidermal water loss in moisturizers, serums, and gentle cleansers.
What does EOP do in a cosmetic formula?
This ingredient is a barrier-repair and skin-conditioning lipid used to support the stratum corneum lipid matrix and reduce transepidermal water loss in moisturizers, serums, and gentle cleansers.
Is EOP clean?
Clean-beauty frameworks generally view it as well tolerated, low-irritation, and not a common restricted-list issue. Documentation matters because sourcing and production route can vary by supplier.
Is EOP sustainable?
Sourcing is supplier-dependent, with modern grades often made from plant-based or biotechnology-derived precursors, while some may involve synthetic routes. It is lipid-like and not associated with the persistence profile of silicones or fluorinated polymers, though public biodegradation data for specific grades are limited.
Is EOP COSMOS-approved?
COSMOS alignment is grade-dependent: naturally derived or biotechnology-derived material made with permitted processes can fit COSMOS-natural, while fully synthetic routes may not qualify. Its Green Chemistry fit improves when renewable lipid feedstocks, efficient synthesis, and low-residue processing are used.
How does EOP work chemically?
The molecule is an amphiphilic epidermal barrier lipid built from a sphingoid backbone, a very long-chain omega-hydroxy fatty acid, and an ester-linked linoleate segment, which helps organize lamellar structures. It is poorly water soluble, typically used at very low levels around 0.001 to 0.1%, and formulates best in lipid blends with sterols, fatty acids, and mild emulsifier systems.
