caryfh Posted December 23, 2010 Share Posted December 23, 2010 I was testing out a face cream recipe, trying to get the consistency I like prior to modifying the recipe to include all the nice extras I wanted. I love the consistency (nice and thick) but when I first rub it on, it seems to feel slightly tacky/sticky, but then still absorbs nicely and feels great afterwards. Just wondering what I might change to help with this.Recipe includes63% Water4% Humectant (I used sodium lactate)0.5% xanthan gum (I might have used 1% by accident?)7% FCO7% Sesame Oil6% LotionPro 165 (Glyceryl Stearate (and) PEG 100 Stearate Emulsifier)1.5% Vitamin E1.5% cetyl alcoholYes, I recognize that this doesn't add up to 100%, it's just the first 2 phases, but didn't feel the need to add in the last round (including preservative) if I don't love the way these act together. Is it perhaps too much xanthan gum? would adding dimethicone help? Quote Link to comment Share on other sites More sharing options...
Abbiepql Posted December 27, 2010 Share Posted December 27, 2010 I am not familar with Lotionpro 165, but as an emulsifier, that rate looks a bit high to me as does the sodium lactate which I have always learned to keep under 2%. I think the emulsifier is what is giving you the tackiness, especially coupled with the oils you chose for this recipe. I use cones in all my lotions and creams due to the nice slip factor. I would fix the recipe first then add the cones taking from your oil pecentage I do 2%. Also as for the thickener, don't use them with cetyl alchol which will thicken, and for a cream I would be using less water to keep it stiffer? Hope that makes sense.

caryfh Posted December 27, 2010 Author Share Posted December 27, 2010 Sorry, what are cones? I was thinking I may play with different emulsifiers and perhaps drop the xanthan gum altogether.

mychellec Posted December 28, 2010 Share Posted December 28, 2010 I agree that your emulsifier may be the culprit, though I haven't played with Lotionpro either. You might try BTMS for your emulsifier. It has a nice, almost powdery feel in lotions and creams and it adsorbs to and conditions skin. I agree that you want to keep the sodium lactate at 2% as it is photo-sensitizing, and your Vitamin E should be at 1% or less. I love the feel of cylcomethicone in my lotions as well. FCO is a nice light oil, so that will not add tackiness to your formula; sesame is a bit more occlusive but still should not be sticky. I do love the glide cetyl contributes to a formula, and have never found it to be sticky, but play with it and see. HTH! Quote Link to comment Share on other sites More sharing options...
