Functions

• Excellent Solubilizer

  Glycols have been used in cosmetics and personal care products to impart beneficialproperties such as humectancy, solvency, moisturization and emulsification.One suchingredient is 1,3-propanediol (PDO).

• Humectant

  1,3-propanediol was more efficient than BG and PG in moisturising the skin throughout the entire four hour testing period. And 10% 1,3-PDO solution provides better skin moisturisation during the initial application, but the solution containing 5% 1,3-PDO/5% glycerin has the best overall moisturisation effect.

• Sensorial Enhancer

  Formulating with 1,3-propanediol /glycerin mixture may reduce the tackiness effect resulting from a higher concentration of glycerin alone.

• Preservative Booster

  Propanediol is increasingly added to formulations or used directly as extraction solvents especially in the case of natural extracts, as a texturizing agent or humectant but also for stabilization and preservation urposes. Kerdudo et al. demonstrated that propylene glycol and propanediol have preservative properties.
