  • Help! My moisturizer is “sweating” water when applied

    Hi everyone,

    I’ve been experimenting with making a basic moisturizer, but I’m encountering a problem. When I apply the cream to my skin and massage it in, it releases water, almost as if it is condensing. At first, the cream looks great, smooth and glossy, but the next day, it thickens, and when applied, it releases water after a few strokes. This makes it feel unsatisfying. I have also tested increasing nad decreasing different ingredients. Here is an example of my recent experiment, as you can see it’s a very basic formulation:


    50 ml batch:

    Water Phase (72%):

    Destilled water: 33g (66%)

    Glycerin: 3g (6%)


    Oil Phase (27%):

    Jojoba oil: 9,5g (19%)

    Glyceryl Strearate SE: 4g (8%)

    Preservative:

    0,5g (1%)

    Details:

    • I heat both the water phase and the oil phase to around 70-75 degrees Celsius.
    • I add the oil phase into the water phase and use an ultra turrax for homogenization.
    • The cream initially looks perfect—smooth and glossy.
    • As the temperature drops, I add 1% preservative.
    • After a day, the cream becomes noticeably thicker.
    • When applied to the skin, it releases water after a few strokes.

    Thank you in advance!
