Carrageenan

In Skincare: Is Carrageenan Safe? Comedogenic Rating & Side Effects

Safety (overall safety)
2/5 — Low risk
Irritancy (skin irritation)
2/5 — Low risk

Safety Information

Carrageenan is considered generally safe for use in cosmetics by the Cosmetic Ingredient Review (CIR) Expert Panel. However, degraded forms of carrageenan, such as poligeenan, are not used in personal care products and have been associated with higher irritation potential. The Environmental Working Group (EWG) rates carrageenan with a moderate health concern due to limited evidence of gastrointestinal effects in animal studies, though topical use is not linked to these concerns.

Data & Research

Scientific Facts

Carrageenans are large, flexible molecules that form helical structures. This structure allows them to create gels at room temperature. They are also known for their shear-thinning behavior – meaning they become thinner when agitated or under stress and then return to a thicker consistency once the stress is removed.

Common Uses

Formulation in Carrageenan

Carrageenan and its salts are utilized in cosmetic formulations for their thickening and stabilizing properties. They form gels at room temperature due to their unique molecular structure, which allows them to thin under shear stress and then regain viscosity when the stress is removed. This characteristic makes it suitable for products requiring easy pumping and subsequent thickening during application.
