I am working on a face cream....which is a foreign concept to me....but age is sneaking up, hence the cream. Let me start with, I have naturally oily face skin, and skin that does not absorb heavier oils well, therefore I dislike oily feeling products. So my face cream has an oil phase of about 10%, using very light quick absorbing natural oils, primarily rosehip and raspberry seed.
So I made two identical formulas, with the only difference being one included 3% Penstia. INCI: Adipic Acid/Neopentyl Glycol Crosspolymer.
This was added with the thought that it would enhance the 'first touch feel' of the product. However, somehow in my ignorance and propensity for reading, and asking questions, I seem to have stumbled onto a pretty nice feeling product, without it. (Multiple emulsifiers, and cascading esters.) Since the formula was already pretty silky, I could detect almost no difference, and very little enhancement of the 'first touch feel' I was looking for. Certainly a level of difference where very few consumers could detect a difference.
So the Penstia did not change what I was looking for, but it did make a change. Now I need to determine, from a customer perspective if this is a positive or negative change. I applied the two formulas each to one half of my face. 20-30 minutes after application, when I ran my dry fingers across each side of my face, the side with the Penstia cream, my finger tips had a lite sheen of oil on them. The other side, almost none. So I concluded that the Penstia had slowed the absorption of the oils. The Penstia side also left the skin shinier. Since the primary emulsifier is Montanov 202, the cream does not naturally leave a lot of gloss.
So my question (finally) is.... is the slower absorption an enhancement or a detraction? To me....someone ignorant of facial creams, I want the cream to absorb. To my Korean other half....who has used every name brand cream one can imagine, she likes the gloss, and the slight oil covering left on the skin.
I realize everyone has their own preference, so what I am asking....is what would the 51+% of people prefer? A marketing question/viewpoint.
