1,2-Hexanediol

General Description
1,2-Hexanediol is a versatile, multifunctional ingredient extensively used in the personal care industry. It acts primarily as a high-performance antimicrobial agent and preservative booster, while simultaneously serving as an effective humectant. It is highly valued for its mildness, making it a preferred alternative or adjuvant in modern preservation systems for sensitive skin formulations.

Mechanisms of Action

• Broad-Spectrum Antimicrobial Activity:
  Exhibits significant inhibitory effects against a wide variety of microorganisms, including Gram-positive and Gram-negative bacteria, as well as fungi and yeasts. It disrupts the integrity of microbial cell membranes, thereby effectively preventing contamination and spoilage at the source.

• Preservative Synergy:
  Functions as a potent booster when combined with other preservatives (e.g., Phenoxyethanol, Ethylhexylglycerin). This synergistic effect allows for a reduction in the total concentration of traditional preservatives required in the formula.

• Humectant Activity:
  Contains two hydroxyl groups that bind water molecules, providing auxiliary hydration to the skin and improving the moisture retention capacity of the formulation.

Key Benefits

• Safety & Mildness:
  Characterized by an excellent toxicological profile with low irritation potential. It is exceptionally gentle on the skin and mucous membranes, making it ideal for sensitive skin and hypoallergenic products.

• Formulation Stability & Compatibility:
  Demonstrates superior chemical stability across a wide pH range and temperature spectrum. It is highly compatible with various surfactants, active ingredients, and other antimicrobial agents without destabilizing the system.

• Sensory Optimization:
  Enhances the sensory attributes of the final product, contributing to a lighter, non-sticky skin feel while aiding in the solubilization of active ingredients.

Applications & Compatibility

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

• Formulation Suitability: Universally applicable in toners, serums, emulsions (creams/lotions), and facial masks.

• Primary Functions: Preservative/Antimicrobial Booster, Humectant, Solvent, Skin Conditioning Agent.
