C10-18 Triglycerides
Brief Description
C10-18 Triglycerides are naturally derived fatty acid esters commonly used as emollients and texture enhancers in cosmetic formulations. They are derived from plant-based oils and serve as skin-conditioning agents, providing hydration, barrier protection, and a smooth, non-greasy feel. Due to their excellent skin compatibility, they are widely used in moisturizers, creams, and other personal care products.

-
How to Incorporate into Skincare Formulations
-
Oil Phase Addition:
-
Melt C10-18 Triglycerides and add them to the oil phase of emulsions or anhydrous formulations.
-
Recommended melting temperature: 40°C - 50°C.
-
-
Blending with Emollients:
-
Works well with other plant-derived oils, esters, and butters to enhance skin-feel.
-
-
Emulsification Process:
-
In emulsions, blend into the oil phase before homogenization to ensure even distribution.
-
Compatible with water-in-oil and oil-in-water emulsifiers.
-
-
Post-Formulation Checks:
-
Ensure stability by testing at different temperatures.
-
Adjust levels based on the desired texture and spreadability.
-
Heat Sensitivity
C10-18 Triglycerides are heat-stable and can tolerate processing temperatures up to 80°C without significant degradation. However, prolonged exposure to high heat should be minimized to maintain the integrity of the ingredient.
Scientific Data on Efficacy
-
Skin Hydration: Functions as an occlusive agent to lock in moisture and prevent trans-epidermal water loss (TEWL).
-
Barrier Function Support: Enhances lipid layers in the skin, reinforcing the natural barrier.
-
Softening & Conditioning: Provides a non-greasy, smooth texture that improves skin suppleness.
-
Stability Enhancer: Helps to stabilize formulations by contributing to texture and viscosity.
Reasons to Use in Formulations
-
Enhances product texture and spreadability.
-
Provides deep hydration without heaviness.
-
Offers excellent skin compatibility for sensitive and dry skin.
-
Improves stability and consistency in emulsions.
-
Compatible with both water-in-oil and oil-in-water emulsions.
Consequences of Stability Loss in Formulations
-
Exposure to extreme heat (>80°C) may cause breakdown and oxidation.
-
Improper emulsification may lead to texture instability.
-
Rancidity can occur if not properly stored in airtight containers away from light and heat.
Possible Alternatives
-
Caprylic/Capric Triglycerides: Lighter-feel emollient with similar skin-conditioning benefits.
-
C12-15 Alkyl Benzoate: Provides lightweight, silky texture while enhancing spreadability.
-
Shea Butter Esters: Offers deep hydration with a heavier texture.
Where C10-18 Triglycerides are Found in Skincare Products

-
Lip Balms & Butters: Improves texture and smoothness.
-
Sunscreens: Helps stabilize formulations and improve spreadability.
-
Hair Conditioners: Adds softness and manageability.
-
Foundations & Makeup: Contributes to a creamy, blendable texture.
