  • Cooling and tingling effect in sexual wellness cosmetics

    Hey guys! 👋

    I’m currently working on the development of formulas aimed at the sexual wellness market. We’re doing well and making progress, but I’m dealing with some difficulties…

    Our benchmarks that show a tingling and/or refreshing sensation have Menthol in their composition, but when I try to formulate these products and apply to an area of skin (back of hand or palm), I don’t feel the effect. I tried with Menthyl Lactate as well, but I didn’t have positive results. Maybe concentration is the problem?

    I thought it might also be the region where I’m applying it to test it, but I don’t have the balls to test you-know-where… 😳

    Remembering that I am formulating from Brazil, so the regulation here may be different from yours, but the question is about the minimum % to feel the effect (in the case of the gel, I can smell the freshness, but not feel it on the skin)

    Here’s the benchmarks and the formulations we made



    Cyclopentasiloxane (and) Dimethiconol -> qsp (100%)

    Cyclopentasiloxane -> 15%

    Menthol -> 0.6%



    Dicaprylyl Ether -> qsp (100%)

    Cocoa Butter -> 3%

    Shea Butter -> 1.5%

    Sweet Almond Oil -> 5%

    Beeswax -> 25%

    Menthol -> 0.1%

    Vitamin E -> 1%

    Mint Fragrance -> 1%

    Thank you all for your attention 🙂

    Yes, where you apply matters. Some areas of the body have a higher density of nerve endings and will experience a greater sensation.

      A colleague tried the application on the lips, since it is a mucosa, and we had no effect either… regarding the terminal endings, I imagined that the palm of the hand (despite not having as many as the intimate region in question) had been a good choice … I don’t think anyone will volunteer for the tests now 😳

        The lips should be a good approximation but not quite.

    Are you sure you are using proper Menthol?

    I have refreshing face wash with 0.15% Menthol in it (if I remember correctly) and it does cool the face and give the fresh feel. I cannot imagine putting more than 0.05% you-know-where ..

      As strange as it sounds, yes I do. It’s the same one we use in some shampoos where it’s clearly possible to feel the cooling effect… we increased the concentration because we hadn’t felt anything before, but maybe if we had tested it in the female region the effect would be expressive…

      I think this is one of the greater difficulties in formulating cosmetics, when you try to do something specific for a niche that you are not part of and never had contact with other products

    Yesterday we carried out three more tests, one on the back of the hand, one on the sole of the foot and one on the upper region of the lips. On the back of the hand there was no effect, while on the foot it was possible to feel a slight coolness (I thought it was funny, like tickling 😆). As for the lips, in the upper part (inside) the sensation was very vivid (it had no effect on the outside). When we tested it on the bottom lip, we didn’t feel anything on either side… how crazy

    Of course, all this refers to the pleasure gel, I haven’t tested it with the balm yet, but maybe that’s the way to go… I’ll have to use the upper lip (inside) as a parameter and adjust the concentrations until the effect is milder…

    Is there any other component that has menthol or any refreshing active that you recommend for these cases, that is less irritating?
