  • Warming Effect personal Lube / Lubricant

    Posted by Heroics123 on February 3, 2025 at 3:05 am

    I am struggling with formulation to make Lubricant. Ingredients are as follows
    Glycerine (80-90%)
    PQ7 (6-7%)
    PG (2-5%)
    functional ingredients (Niacinamide, Larginine) (0.1!)
    preservative
    stabilizer

    This is very well in durable gliding with less tackiness but there isn’t any warming effect. Even glycerine is not giving out any warming.

    I do not intent to add any cooling ingredients like menthol or burning effect ingredient rather it should give constant warming and arousing effect on genitals.

    Please advise if any of these can work well -Capsaicin, Vanillyl Butyl Ether (VBE), or Methyl Nicotinate. Durex Cherry is the good example of such product.

    With 80% glycerin, have you checked to see if you even need to preserve it?

    What functionality does L argine have except to help raise the pH in the wrong direction?

    All the ingredients are likely to stimulate blood flow, but you will definitely need to be careful about how much you add. So check the SDS information on hazards generated. And with such a low water content, how soluble will the various ingredients be?

    Just as a disclaimer- personal lubricant does not fall under US cosmetic definition, you need 510(k) clearance which involves pre-market approval of safety (if you are selling to US market).

    Personally I would avoid ‘functional ingredients’, unless you have strong evidence of the safety of each component individually and as a combination for the specific areas of application.

    Are you actually getting any viscosity build from the PQ-7 in polyols? What is ‘stabilizer’?

    Glycerin can produce a mild warming effect when it comes in contact with water- this requires the formula to be mostly anhydrous to start though. I’m assuming the PQ-7 is a solution so you are adding water already, and I’m not aware how safe a polyquat is for vaginal tissues, haven’t seen a polyquat in lube before.

    I have tested methyl nicotinate before for a different application- it certainly produces warming. I would start with a low amount (0.1-0.5%), I’m not sure how well it will be solubilized in a polyol base.
