I just think the total content of them would be around 1%.

How much is enough? I guess 0.3% is ok, right? I have read some articles, they even use only 0.1%

I tried sodium lactate, and it was really bad for my system, as was sodium PCA, I know that. I just have some hope when I put salt in this system and I’ll give them up without any regrets

I like it because it gives good moisture without being sticky, sadly I guess I’ve to leave it out of the formula. Thanks so much

Yes, since my formula has 0.5% resveratrol, 0.5% extract, I want a little BHT to stabilize the formula

Also my desired pH would be around 5.5-6.0
