Science
Mechanism of Action
This ingredient operates as a Low-Molecular-Weight Gelator (LMWG) that organizes into a three-dimensional, nanofibrillar 'butterfly' network. Through supramolecular hydrogen bonding and pi-pi stacking, it creates a microscopic mesh that traps organic solvents, effectively solidifying them into clear, stable sticks or anhydrous gels.

Clinical Evidence

Key findings
- 01 Research indicates that at 0.5%, it forms a supramolecular hybrid capable of facilitating the controlled release of lipophilic active ingredients.
- 02 Studies at a 1.0% concentration demonstrate the formation of a stable, thermally reversible 3D network in polyols, providing the necessary structural integrity for solid cosmetic sticks.

Dusting Analysis
As a structural gelling agent, Benzylidene Sorbitol is rarely 'dusted' because it must reach a critical concentration (typically above 0.5%) to successfully form a stable gel network; failure to use an adequate amount results in a formulation that remains liquid.
The Formula
Formulation
Stability
Highly acid-sensitive; the acetal structure undergoes hydrolysis and decomposes at a pH below 4.0. It requires a neutral to slightly alkaline environment for long-term stability.
Synergies
- Propylene Glycol
- Glycerin
- Ethanol
- Lipophilic delivery systems
Conflicts
- Mineral acids
- Strong oxidizing agents
- High concentrations of halides (Chloride, Bromide)
- Formulations with high water content
Safety
Safety Profile
While not formally reviewed by the CIR, it is classified as safe by the FDA for food-contact materials and is listed on the EU CosIng database without restrictive annexes.
