  • Parabens Optional? Beeswax/Honey/EO Blend

    Posted by mmckrell on October 23, 2024 at 6:03 pm

    I’m new to formulating cosmetics, and am looking to make a face cleanser & makeup remover based on Lush’s Ultrabland product. This product is just for me-I wouldn’t be selling or distributing to others.

    My plan is to make what I think is an anhydrous solution containing beeswax, honey, and essential oils (sweet almond, rosehip, geranium). I’ve also seen copycat recipes that involve rose water.

    1. If I go with the anhydrous solution, it is a must to incorporate parabens? I’ve read that this isn’t necessary, but that some people include them anyway, just to be safe. Lush’s recipe includes methylparaben, propylparaben, and glycerine. https://www.lush.com/us/en_us/p/ultrabland-facial-cleanser

    2. If I incorporate rosewater, would Liquid Germall Plus be sufficient as a broad-spectrum preservative? This seems to be the go-to for many DIYers.

    Thanks for sharing your expertise with me.

      Thanks! This thread has great info. Sounds like I need to consider incorporating an emulsifier.

      I am still curious whether preservatives would be recommended for the mixture I posted above.

    Preservatives are often not required for anhydrous blends but honey is not anhydrous and you would be best to leave it out if you are only going to use oils and beeswax. FYI-Sweet almond and Rosehip are carrier oils (or emollients) and not essential oils.

    If you add water (or water soluble ingredients) it is necessary to use a preservative. It is also necessary to use preservatives if your product will come into contact with water. The preservative you use will depend on the product type (e.g emulsion, surfactant blend) and pH.

    Here is a good review of the common preservatives and their limitations.
