Replacing natural betaine with glycerin…….
In my chase to create a premium lotion…I went down the humectant bunny trail with natural betaine (@ 3% inclusion rate). I was using it in conjunction with sodium lactate (@ 2%), and hyaluronic acid (a 1% solution was included at 9% of formula). The end result…was amazing.
However…as I look to go from formulation…..to production, the betaine is both costly, and given me a bit of grief in the always above 90% humidity environment I live in (Hawaii). So for pure simplicity…I am thinking about dropping the betaine and replacing it with good old…(cheap)… glycerin. Since I will keep the Sodium lactate and hyaluronic acid… at what rate should I include the glycerin? I was thinking….1 to 2%? Any thoughts? … I always like the thought of my ingredients working in synergy with each other.
Formula is 14% blended natural oils…and 4% blended butters, one being Cupuacu. The water has added Aloe 100X, @1 to 99.
*** The reason I left glycerin out in the beginning….is there are some negative perceptions about it. I am open to other suggestions for humectants…that add value and skin feel.
