Science
Mechanism of Action
This ingredient creates a thin hydro-lipidic film, effectively preventing trans-epidermal water loss (TEWL) and enhancing the even distribution of oil-soluble components like UV filters. It also functions as a viscosity-increasing agent and co-emulsifier, stabilizing oil-in-water formulations.
Research
Clinical Evidence
High confidence1.6%
Key findings
- 01 A 2017 CIR survey reported 1.6% as the maximum concentration of use for Lard Glyceride, with no toxicity observed at typical levels.
- 02 Historically, concentrations up to 10% have been utilized in cosmetic products, with its safety reaffirmed by the CIR expert panel within established impurity limits.

The Formula
Formulation
Stability
As an ester, it is prone to hydrolysis outside the optimal pH range of 5.0-8.0, making it unstable in highly acidic or alkaline environments. It is often employed in nanodispersions to stabilize hydrophobic substances effectively.
Synergies
- Enhances distribution of oil-soluble ingredients (e.g., UV filters)
Conflicts
- Strong oxidizing agents
- Strong acids
- Strong bases
Safety
Safety Profile
Its safety is conditional on strict limits for heavy metal and pesticide contaminants, such as lead (<0.1 ppm), arsenic (<3 ppm), and mercury (<1 ppm). Its precursor, lard, is classified as GRAS by the FDA.
