Ethylhexylglycerin

General Description
Caprylyl Glycol is a high-performance, multifunctional ingredient widely utilized in the personal care industry as a broad-spectrum antimicrobial agent and humectant. It is a cornerstone component for developing "Preservative-Free" or alternative preservation systems. Distinguished by its exceptional mildness and safety profile (EWG Score: 1), it effectively inhibits microbial growth while providing skin conditioning benefits.

Mechanisms of Action

• Antimicrobial Action:
  Disrupts the cell membrane structure of microorganisms and inhibits energy metabolism. This mechanism delivers potent, broad-spectrum activity against Gram-positive and Gram-negative bacteria, molds, and yeasts.

• Synergistic Boosting:
  Acts as a powerful preservation booster. When combined with traditional preservatives (e.g., Phenoxyethanol, Ethylhexylglycerin), it significantly enhances antimicrobial efficacy, allowing for a 30% - 50% reduction in total preservative dosage.

• Dual-Function Hydration:
  Its diol structure (two hydroxyl groups) binds water for moisturization, while its short lipophilic chain aids in barrier repair and improves skin affinity.

Key Benefits

• Safety & High Tolerance:
  Exhibits an excellent safety profile with minimal irritation potential. It is suitable for sensitive skin and infant care products. Its regulatory classification often allows for "Preservative-Free" marketing claims.

• Broad-Spectrum & Efficient:
  Provides reliable protection against a wide range of pathogenic microorganisms, ensuring product safety from the source.

• Formulation Stability:
  Highly stable across a wide pH range (pH 2 - 12) and resistant to temperatures up to 70°C. It is compatible with virtually all surfactants and active ingredients without compromising their efficacy.

• Sensory & Texture Optimization:
  Functions as a viscosity regulator and wetting agent, improving the spreadability and slip of the formulation while providing emollient properties.

Applications & Compatibility

• Target Industries: Personal Care (Skincare, Baby Care), Color Cosmetics, and Hair Care.

• Formulation Suitability: Ideal for lotions, creams, serums, and "clean beauty" formulations requiring alternative preservation.

• Primary Functions: Antimicrobial/Preservative Booster, Humectant, Skin Conditioning Agent, "Preservative-Free" System Builder.
