EntrepreneurOctober 19, 2021 at 2:08 am in reply to: What Percentage of surfactant is in solution of shampoo when we apply it to hair?@Perry i got your point.
I have experienced that if you apply shampoo to dry hair it doesn’t foam well and if you apply a Shampoo with high surfactant percentage like 20% it foam but if you add some extra water on hair after applying shampoo the foam increase a lot. It means there is a certain range of surfactant percentage in water that foam to maximum. If it is too diluted it doesn’t foam well and if it is not enough diluted it doesn’t foam well. So what is that percentage range of surfactant in water that foam most?
One way to find this may be be to make several samples with 1,2,3,4,5,6,7,8,9,10% surfactant and apply each to dry hair and see which one foam better. But if someone knows that it will same me time and everything.

EntrepreneurOctober 17, 2021 at 2:24 pm in reply to: Is it safe to formulate 2% salicylic acid or 8% lactic acid at pH 3?@Microformulation i am not in US and not selling in US so those restrictions aren’t for me but as guidelines.
If something is OTC in US it means that product is curing a disease. Am i correct?
I want to cure the problems with these ingredients but not in US and there is not restrictions for these ingredients in Asia.

EntrepreneurOctober 17, 2021 at 1:51 pm in reply to: How do they support this claim and what ingredient does it? (Up to 95% less hairfall)Does antioxidants reduce oxidative stress?
If yes then which one is stronger antioxidants?
1. Ingredients like Piroctone Olamine ,niacinamide or Panthenol as here.
2. Ingredients like tocopherol, BHT or ascorbic acid.
Also for chelating iron, does chelating iron with EDTA or phytic acid have the same effect as Piroctone Olamine of this same purpose?

What percentage minimum and maximum salicylic acid and lactic acid are OTC? In separate products.I was thinking 0.5-2% salicylic acid is OTC.

Yeah we are discussing the same ingredient.
Because it works better at this ratio than what you said in shampoo.
What is the product?
-
@Perry 1% cetrimonium chloride which is 0.3% cationic surfactant?
Was there another silicone or cationic surfactant in this product?

No exposure to sun, no vitamin D from sun.As much as i know black people have better skin than white people and black people expose their skin more to sun than white people.
Vitamin D doesn’t have to come from the sun. You can get it through a multivitamin or fortified foods as Perry said. Even milk has some Vitamin D.
yes you can but Don’t you sometimes think that sun may have more benefits other than vitamin D that we would discover in the future?
I’ve read that Vitamin D can’t pass through windows. You have to be outside to get it, and many people don’t have the opportunity to do that regularly.
yes. Vitamin D is made by help of UVB directly hitting the skin.. Window blocks UVB. Your SPF sunscreen blocks UVB. So if you are inside then what is the benefit of applying SPF sunscreen? There isn’t UVB at first place.
aging is caused by UVA. Window doesn’t block UVA, your SPF 50 doesn’t block UVA. So what is the benefit of using SPF 50 or not going in sun for preventing fast aging caused by UVA?
People likely got a lot more Vitamin D 100 years ago.Black people have better skin supposedly because of their higher melanin. It better protects against photodamage.
may be. may be it is because they don’t protect themselves from sun like white people do.Although lines/wrinkles/spots are only one part of skin aging. Sagging is the other…and that has to do with collagen and elastin loss.
in my experience being inside building all the time makes my muscles and skin weak and saggy even if i take vitamin D supplements. Going in the sun naked daily specially mid day gives me muscle energy and my skin feel better. Although morning sun makes me tired ????.Melanin isn’t related to that, at least I don’t think. This article explains it pretty well: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4756870/

EntrepreneurOctober 16, 2021 at 2:19 am in reply to: Is daily use of an SPF product recommended?@Perry isn’t the purpose of sunscreen and SPF blocking UVB not UVA?
You can use SPF 50 every two hour without blocking UVA that causes aging. Then what is the benefit?

EntrepreneurOctober 15, 2021 at 2:31 pm in reply to: How do they support this claim and what ingredient does it? (Up to 95% less hairfall)@PhilGeis good point but how you claim and support it is very important especially in a product that doesn’t do what people think it does for example reducing hair fall by shampooing it.

As much as i know black people have better skin than white people and black people expose their skin more to sun than white people.
What causes the skin look aged from sun exposure? UVA or UVB or something just light or something else?
