Science
Mechanism of Action
This carrageenan derivative acts as a highly effective moisturizer due to its significant carbohydrate content, attracting and binding moisture to the skin's surface. It forms a lightweight, occlusive film that measurably reduces transepidermal water loss (TEWL), thereby sustaining optimal skin hydration and promoting a soft, supple complexion. Furthermore, it supports the skin's natural barrier function and contributes to robust product aesthetics by acting as a gelling, thickening, and stabilizing agent within formulations.

The Formula
Formulation
Stability
As a sodium salt, SODIUM/TEA-UNDECYLENOYL CARRAGEENAN exhibits solubility in cold water, while general carrageenans typically require hot water (40-70°C) for dissolution. Its gelation and overall stability within a formulation are highly influenced by factors such as temperature, ionic strength, and the presence of specific ions. Optimal pH for stability is variable, with some iota-carrageenan emulsions showing stability around pH 6 and kappa-carrageenan enzymes demonstrating excellent pH stability.
Safety
Safety Profile
Carrageenan, the foundational ingredient, holds a Generally Recognized As Safe (GRAS) status by the U.S. FDA for food applications, and its safety for cosmetic use is widely acknowledged by scientific and regulatory bodies. Cosmetic-grade carrageenan consists of large molecules that do not absorb into the body, differentiating it from degraded carrageenan (poligeenan), which is not utilized in skincare and has been the focus of ingestion-related safety discussions.

Verdict
SODIUM/TEA-UNDECYLENOYL CARRAGEENAN offers valuable hydration and formulation stability with low irritancy, but its high comedogenicity suggests it may not be ideal for oily or acne-prone skin types.
