  • Personal lubricant (with warming and cooling)

    I thought I’d share a simple recipe for lube. I used this forum a bunch. I made a video:

    But I can save you from the incoherent babbling:

    93% distilled water

    5% propylene glycol

    1.5% HEC (might change based on grade)

    0.2% potassium sorbate

    0.2% sodium benzoate

    q.w. Citric acid to pH

    ​For warming add 4 drops of wintergreen extract into 15mL of the HEC recipe above.

    For cooling add 2 drops of peppermint extract into 15mL of the HEC recipe above.

    For insane local vasodilation, use 0.05% methyl nicotinate.

    I don’t have the grade of HEC… it is a E1525 food grade. I assume it’s between 2k and 4k, but I need to contact the vendor.

    From other discussions on these forums, yes there is a slight synergistic effect from potassium sorbate and sodium benzoate. But the main reason for using it was that’s what I had. I found a supplier that sells in small quantities every ingredient I could want, so I’ll have new recipes when it all arrives.
