Home Cosmetic Science Talk Formulating Condensation on the lid

  • Condensation on the lid

    Hi! I have a formulation that is producing condensation on the lid but only in one environment. (On my desk at school in a room approximately 73 degrees F. At home in 70 degrees F with night and day fluctuations it does not do this.) This is the only formula that I have experienced this issue with. It is a hand cream made with glycerin, xanthan gum, water, 1% hyaluronic acid, propanediol, sea kelp bioferment, panthenol powder, olivem 1000, safflower oil, hazelnut oil, cetyl alcohol, vitamin E, and germall plus. Do any ingredients pop out as problematic? I am new at this and unsure how to begin troubleshooting. Any advice is welcome. Thank you. 😃

    @Kristina Do you mean inside the lid of the jar, not on the lid itself, meaning atop of it? I would have no explanation for moisture vapor atop the jar lid. Inside the jar happens whenever you cap it while still hot. This low temperature condensation may be somewhat mitigated by adding to your formula more glycol or glycerin or xylitol, sorbitol, any polyol that forms a eutectic mixture with water.

      Yes, inside the lid weeks after bottling. Product was cooled before capping. I will try modifying the film forming ingredients. Thanks for the advice.
