Suggested Ingredient for Pungent/Volatile Scent in Cream

Finding an ingredient with a smell exactly like dipropylene glycol but stronger, or a specific pungent/medicinal smell that disappears quickly, can be challenging as scent perception is subjective.

However, based on your requirements for a water-soluble ingredient with a potentially pungent or medicinal scent that is volatile and suitable for a cream formulation, Menthol Water Soluble (20% Menthol, Liquid) could be a suitable option.

• Properties: This ingredient is water-soluble and provides a distinct menthol scent and a cooling sensation. Menthol's aroma is often described as minty, but can also be perceived as pungent or medicinal by some.
• Volatility: Menthol is known for its volatility, meaning its scent and cooling effect dissipate over time after application, which aligns with your need for the smell to disappear after the cream is applied.
• Usage: It is designed to be easily dissolved in water-based formulations like creams.

While the scent is not identical to dipropylene glycol, its characteristics (water-soluble, distinct volatile scent, suitable for topical use) match your description of a pungent, volatile, medicinal-like smell that fades after application.
