Octyldodecyl Citrate Crosspolymer

Octyldodecyl Citrate Crosspolymer is a synthetic polymer derived from citric acid and long-chain alcohols. It belongs to a class of ingredients known as humectants, which work by attracting water molecules from the environment and deeper skin layers to the surface.In skincare formulations, this ingredient functions as both a humectant and a film-former, meaning it not only draws moisture to the skin but also helps create a light protective layer that reduces transepidermal water loss. It is typically used in concentrations that allow it to feel lightweight on the skin.

As a humectant, Octyldodecyl Citrate Crosspolymer has an affinity for water molecules. When applied to skin, it draws moisture from both the air (if humidity is present) and from deeper layers of the epidermis, delivering it to the outer layer where it is most noticeable.The crosspolymer structure also allows the ingredient to form a thin, flexible film on the skin surface. This film helps to seal in moisture without creating the heavy occlusion of traditional emollients, making it a useful ingredient for balancing hydration and breathability.

This ingredient is typically found in serums, moisturisers, and hydrating treatments. It works well in formulations designed to boost hydration without adding heaviness. For best results, apply to clean, slightly damp skin and follow with a compatible moisturiser or occlusives to lock in the hydrating benefits. It can be used daily as part of both morning and evening routines.

Generally well-tolerated and suitable for most skin types. No significant safety concerns have been reported in typical cosmetic concentrations, though patch testing is advisable for those with known sensitivity to polymers.
