Science
Mechanism of Action
This ingredient acts as a powerful skin conditioning emollient, primarily due to its composition as a triglyceride of conjugated linoleic acid, derived from safflower oil. It delivers essential fatty acids, specifically linoleic acid, which are critical for strengthening the epidermal barrier and thus minimizing transepidermal water loss (TEWL). Additionally, its inherent phytosterols serve as humectants, attracting and retaining water within the skin to boost hydration. Its light texture and rapid absorption make it a versatile choice for a diverse range of skin types.

Stability
While specific stability data for Isomerized Safflower Glycerides is not detailed, the general principles for safflower oil suggest storage in a cool, dark environment to prevent oxidation, which could alter its properties and potentially increase comedogenicity. It is insoluble in water but miscible with oil and fat solvents.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated Isomerized Safflower Glycerides within the broader category of triglycerides, concluding they are generally safe for cosmetic applications when formulated to mitigate potential irritation. While a specific maximum concentration for Isomerized Safflower Glycerides itself is not provided, a separate CIR review deemed related PEGylated alkyl glycerides safe up to 10% in leave-on products. Safflower oil, its foundational component, is recognized by the FDA as an approved indirect food additive and a common food ingredient. The EWG Skin Deep database indicates a low concern for irritation (skin, eyes, lungs) but notes the weight of evidence for this specific concern as unknown/unassessed.
