What does Dipropylene Glycol do in a formulation?

In formulations, its primary functions are:

• Solvent (for dissolving fragrances, oils, and other ingredients)
• Humectant (attracts and retains moisture)
• Plasticizer (increases flexibility and reduces brittleness)
• Viscosity Controlling Agent
• Masking Agent (reduces or masks undesired base odors)
• Emollient (softens and smooths the skin)

Safety Profile:

Hazard Classification: Generally regarded as safe for use in cosmetics with low toxicity. It is not classified as a hazardous substance under standard criteria like GHS for acute toxicity, though proper industrial handling is always advised.

Primary Hazards:

· Combustible Liquid: Has a flash point of approximately 121°C (250°F).

· Irritant: May cause mild irritation to eyes or skin with prolonged exposure.

  Safety Precautions: Use with adequate ventilation. Avoid prolonged skin contact and eye exposure. Keep away from heat and ignition sources. Refer to the supplier's Safety Data Sheet (SDS) for specific handling instructions.
