Science
Mechanism of Action
This ingredient delivers advanced moisturizing by supplying glycerin and a beneficial blend of fatty acids, including oleic, palmitic, and stearic acids. Oleic acid enhances skin penetration, strengthens the natural barrier, and minimizes transepidermal water loss. Palmitic acid supports the skin's lipid barrier to prevent moisture loss and maintain elasticity, while stearic acid acts as an emollient, contributing to softer, hydrated skin. Lard Glycerides also provide vitamins A and D, essential for cell repair, inflammation reduction, and collagen synthesis, alongside antioxidant Vitamin E to protect against free radical damage. Omega-3 and omega-6 fatty acids further contribute to anti-inflammatory effects and sustained hydration. Its mild antimicrobial properties support overall skin health and may help reduce acne-causing bacteria. Notably, its composition closely mimics human skin's natural sebum, ensuring easy absorption without pore occlusion, and it naturally aligns with the skin's typical acidic pH (4.7-5.7) to preserve the protective acid mantle.

Dusting Analysis
Lard Glycerides exhibit multiple functional properties within cosmetic formulations, including skin conditioning, emollience, and emulsification, negating concerns of it being a dusting ingredient.
The Formula
Formulation
Stability
Lard Glycerides are characterized by their oil solubility and insolubility in water, yet they effectively function as an emulsifying agent. Comprising both lipophilic and hydrophilic segments, they facilitate the creation of stable oil-in-water emulsions. While no specific optimal pH range for the ingredient's intrinsic stability has been identified, it naturally harmonizes with the typical acidic pH of human skin, ranging from 4.7 to 5.7.
Conflicts
- Heavy metals (lead, arsenic, mercury) exceeding specified limits
- Pesticides and polychlorinated biphenyl (PCB) contamination exceeding specified limits
Safety
Safety Profile
The CIR Expert Panel has affirmed Lard Glycerides, along with other Lard-derived compounds, as safe for use in cosmetic and personal care formulations. This safety is contingent upon adherence to stringent limitations on contaminants: lead not exceeding 0.1 ppm, arsenic ≤3 ppm, mercury ≤1 ppm, and total PCB/pesticide contamination not more than 40 ppm (with no single residue over 10 ppm). Lard itself holds a Generally Recognized As Safe (GRAS) designation by the FDA. While a 2016 industry survey reported no specific concentrations for Lard Glycerides, Lard Glyceride (the monoglyceride) was reported at a maximum concentration of 1.6% in 2017 and up to 10% in original reports.
