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.


INCI Name

C10-18 Triglycerides


Appearance

A soft, waxy to semi-solid material, varying from off-white to pale yellow.


Formulation Guidance

  • Solubility: Oil-soluble

  • Usage Rate: 1% - 10%

  • pH Stability Range: 3.5 - 8.0

  • Formulation Type: Suitable for emulsions, balms, butters, and anhydrous products.

  • Processing:

    • Mix with the oil phase and melt at 40°C - 50°C.

    • Works well with other emollients, stabilizers, and emulsifiers.

    • Provides improved spreadability and luxurious skin feel.


How to Incorporate into Skincare Formulations

  1. 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.

  2. Blending with Emollients:

    • Works well with other plant-derived oils, esters, and butters to enhance skin-feel.

  3. 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.

  4. 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

  • Moisturizers & Creams: Enhances hydration and skin feel.

  • 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.
