DIMETHYLDIBENZYLIDENE SORBITOL.

Avoid CAS 135861-56-2 / VISCOSITY CONTROLLING

Dimethyldibenzylidene Sorbitol (DMDBS) is widely recognized in polymer science as a nucleating and clarifying agent, forming intricate nanoscale networks to influence material crystallization. Although broadly classified as a viscosity controlling agent for cosmetic applications, its direct utility and specific effects on skin are not substantiated by available research.

Summary

Viscosity controlling agent (general cosmetic classification)

Science

Mechanism of Action

While Dimethyldibenzylidene Sorbitol is understood to self-assemble into a three-dimensional fibrillar network in polymeric and organic semiconductor systems, promoting crystal nucleation, there is no information available that describes a specific mechanism of action or any direct benefits on human skin.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

According to Regulation (EC) No 1272/2008 (CLP), Dimethyldibenzylidene Sorbitol is classified as a Category 2 skin irritant, a Category 2 serious eye irritant, and a Category 1 sensitizer, indicating it may cause an allergic skin reaction. The U.S. FDA lists DMDBS as a Food Contact Substance (FCS) with a Cumulative Estimated Daily Intake (CEDI) of 1 µg/kg bw/d for indirect food contact applications. It is critical to note that these safety classifications originate from industrial handling and food contact material assessments, not from a dedicated direct cosmetic ingredient safety review by bodies such as CIR or SCCS.

Our Assessment

Verdict

Avoid

Due to the absence of demonstrated efficacy or a clear mechanism of action on human skin, coupled with classifications indicating potential for skin irritation and sensitization, this ingredient is not suitable for precision skincare formulations.
