Science
Mechanism of Action
This hybrid cosmetic ingredient synergistically combines sodium mannuronate with methylsilanol, forming a foundational network on the skin. It functions as an effective humectant, efficiently binding and retaining water within the product and on the skin's surface. Its anti-aging efficacy is multifaceted: it actively protects against free radicals, safeguards critical proteins such as elastin and collagen from glycation (the formation of Advanced Glycation End Products - AGEs), and stimulates their enhanced production. The silicon component is considered vital for maintaining collagen and elastin in their optimal, unaltered state. Furthermore, it exhibits anti-inflammatory properties and stabilizes extracellular matrix (ECM) proteins and glycosaminoglycans through hydrogen bonding, thereby reinforcing skin structures and boosting hydration. In vitro studies confirm its capacity to significantly increase fibroblast gene expression for key components like hyaluronan synthase type 2 (HAS2), collagen type I, and elastin.

Formulation
Stability
This ingredient maintains stability within a pH range of 3.5 to 7.0. Formulations should strictly avoid highly acidic conditions (pH below 4) or highly alkaline conditions (pH above 9), as these extremes may induce silanol condensation or polymer breakdown. Additionally, temperatures exceeding 40°C should be avoided to preserve ingredient integrity.
Conflicts
- High levels of Alcohol
- High levels of Calcium Salts
- High levels of Glycol
- Highly acidic formulations (pH <4)
- Highly alkaline formulations (pH >9)
Safety
Safety Profile
Sodium Mannuronate Methylsilanol has not been directly reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. However, related ingredients such as Hyaluronates and Monosaccharides/Disaccharides have been deemed safe for use in cosmetics. The ingredient is reported as non-allergenic and non-reactive, with preliminary studies suggesting a low potential for irritation. An in vitro study confirmed no toxicity to human fibroblasts at a concentration of 1 mg/mL. Regulatory bodies, such as the FDA (Thailand), permit claims related to lifting, firming, and anti-cellulite for this ingredient.
