@Perry. Thanks a lot. Can you explain more details on each your input topic. For example, what is “Particle size when you first make the emulsion”?

Thank you so much Perry

@ngarayeva001, we cannot calculate accuracy amount of fatty acids on natural ingredients. But we can calculate [ lower, high] of each.
“Grease Fall” concept is great for formulation.

@ngarayeva001, Babassu oil is not oil liquid. When you put it on the skin, it will smelt and absorb through skin.

@Sibech, thanks a lot for your valued inputs. I appreciate.
I do not have experience on this area. But, I love it.
I found that linoleic acid staying long without rancid if I use extra virgin coconut in the formula. So far up to 6 months, the cream still OK.
One factor that I learned from @ngarayeva001 is coconut oil can clog pores.
Luckily, I found babassu oil has same characters as coconut oil and doesn’t clog pore.

@ngarayeva001
Oleic acid can be made from our body. But, Linoleic acid cannot be made from body, just from our food or skincare products.

@ngarayeva001, the research indicated that oleic acid is more than linoleic acid in the skin causing acne.
I believe that we need to select the oils based on comedogenic, density, and the most important fatty acids: omega-3, 6, 7, and 9….

@Microformulation, thanks
hlb system is good for starting point. I knew the concept quite well. The difficulty is to identify the good ingredients. I will try next batch next week.
My base is very good, no soaping effect, no grease. It is just for fun!

@Microformulation, thanks.
I am interested on finding the ingredients that can work together for total anti-aging: wrinkles, dark spot, firming, & lifting
