Non-woven sheet mask
Does anybody have any tips on formulating for this type of product?
I recently made a very thin liquid emulsion and impregnated a non-woven paper mask with it. After leaving it on my face for around 5-10 minutes, face mask left a red spot. After 2-3 minutes I started feeling like my face was burning.
From a quick search of products sold at Sephora, I'm seeing all of the available are actually water based serums instead of emulsion. Could this be the problem?
I've gotten rid of many things I've been suspicious about in my formula so right now its basically an emulsion with GMS and cetearyl alcohol, olive oil and shea butter in approximately 65% water, 5% glycerin, preserved with phenoxyethanol, potassium sorbate and sodium benzoate....but mask is still burning.
Thanks in advance!
