In my experience even 0.25% citric acid reduces the pH too much. 

At very low pH sci may not work very well. That is why foam has reduced. 

Keep the pH around 6. 

What preservative are you using? 5% is too much

[Abdullah]

Hec is not compatible with too much glucoside

@ketchito only polymers or surfactants too? 

@Abdullah Only polymers, since they are the poly-electrolytes (the ones that have charge, of course).

Will only mixing polymers like xanthan gum and cationic guar make poly-electrolytes complex or it should be mixed in a specific way?

[Abdullah]

What ingredients do you use? 
INCI names.

[Abdullah]

@ketchito only polymers or surfactants too? 

[Abdullah]

@ketchito is PEC a method or an ingredient? 

[Abdullah]

No it does not in normal use level.

Typing mistake. 
I prefer behentrimonium chloride, not BTMS. 

BTMS has 75% fatty alcohol. I use less.

BTMS 25 has that amount of fatty alcohol to favor formation of a lamellar network. The best (molar) ratio between emulsifier/fatty alcohol for this model is between 1:4 and 1:6. But maybe you use less fatty alcohol to have a more liquid emulsion.

Yes i use BTMC+FA 1:2 weight ratio. It is like 1:3.2 molar ratio. 

I dont like too much fatty alcohol in hair conditioner. 

[Abdullah]

Use less Peg-120.

@Paprik what was your problem with po65? 

I have no problem with it. 

[Abdullah]

Remove cationic surfactant from Shampoo and it will be fine

Another quality and (real) scientific response by @Perry.
I like confirmation bias. LMAO!

Hello to you again, @Abdullah.
You can prove and convince yourself by covering a part of your skin with plastic.

More realistic proof is parts covered by clothes are normally naturally moist/oily.

An even more realistic proof is the folds of skin (joints, fat, wrinkles) on your body. People rarely or never get any imperfections such as acne/pimple in these places, so it is easier to observe.

Those places nearly always having the smoothest and ‘youngest’ appearance without the need for special treatment or product compared to skin exposed to external insults.

The scalp is another very good realistic proof. See those elderly bald people? Only their scalps retain high level of youth while the rest of their bodies die.

@Dtdang I have been using Tretinoin for all my life. I am still using it. According to the Internet, Retinol and Tretinoin are similar to each other. Tretinoin is a controlled item due to its potency (It is banned in certain countries). I am not interested in the types of vitamin-A derivatives in, say Olay Regenerist, because it is too weak OR contains too little of that thing to be useful OR probably does not even have that thing. It is a marketing thing, you know…

I am not sure what you read or told how Retinol actually works. Its primary action is to peel skin. Old skin away, new skin is magically grown. Nothing special to it. AHA and BHA and whatever chemical peels can do the same. Many people even swear that Citrus juices can do the same. I am sure you have heard it over and over. Sometimes concentrated salt solution and sunburn can do the same, these dry/kill the skin, dried/dead and black skin sloughs off, new and white skin mysteriously pops out. What a natural way. LOL! You can see this easily on the beach.

Having said all that, only Tretinoin can touch deep down (messes with DNA). It does not work only at the surface, that is.
Other weaklings vitamin-A derivatives could do it too, I think. But I can say about Tretinoin only because Tretinoin is an extremely well-researched drug for more than 50 years. It is one of those gold standard stuff in medicine.

Now, can mess with DNA does not mean it whitens skin and removes wrinkles the way that most people believe or preach.
“Old” skin still needs to come up.
There is a reason why people on Tretinoin treatment for removing hyperpigmentation are STILL asked NOT to be under the Sun without protection.
There is a reason why the same people who successfully remove whatever they want to have removed are STILL asked NOT to be under the Sun without protection.
They will perpetually go on treatment otherwise. Or blame Tretinoin is shit. (The blame part is common and real story all over the world. Many people using Tretinoin have unrealistic goal and understanding.)

Hello 

Thanks a lot

  PG10S @1% emulsifier in stability or haptic because they are both stable and i am not good at noticing every haptic differences but i didn’t like it because it is a one big chunk emulsifier and ingredients like this take a lot of time and are very difficult to melt specially in large production batches. 

This is a picture of how the sample i had received looks.

I think that is reason enough…to get it from the Thai place… It looks a little more manageable!  

Polyglyceryl-10 Stearate (myskinrecipes.com)

You can ask them before purchasing if the product really looks like that.

[Abdullah]

I like PG6DS more than any of them and i have used a lot of polyglyceryls.

[Abdullah]

I don’t know if you are making products for your self or for sale. 

I didn’t notice any difference with PG6DS alone or 1:1 with  PG10S @1% emulsifier in stability or haptic because they are both stable and i am not good at noticing every haptic differences but i didn’t like it because it is a one big chunk emulsifier and ingredients like this take a lot of time and are very difficult to melt specially in large production batches. 

This is a picture of how the sample i had received looks.

[Abdullah]

I didn’t like it just because PG6DS works better alone or with GMS.

Are you purchasing from thai and ship it to us? 

If yes why don’t you purchase from china? 

I know a supplier who produces all mono and polyglyceryls

[Abdullah]

Yes 
No problem 

[Abdullah]

@Abdullah:

Because Lactic Acid is part of the skin’s Natural Moisturizing Factor, provides more gentle exfoliation than Glycolic, Lactic Acid also increases skin moisturization, and stimulates ceramide and collagen production. It’s a multifunctional molecule.

That is good
Thanks

[Abdullah]

@MarkBroussard one more question.

Why do you use or prefer lactic acid over glycolic acid? 

I use lactic acid too but just because it is less expensive. 

[Abdullah]

For thin hair SPDMA+fatty alcohol 

For thick hair BTMS+fatty alcohol

[Abdullah]

For what type of hair?

[Abdullah]

MarkBroussard said:

@Abdullah:

Yes, the Lactic Acid is loaded at 8%, pH 3.5

Thanks a lot

[Abdullah]

@MarkBroussard can i ask what percentage of lactic acid do you use and at what pH? 

[Abdullah]

Abdullah said:

What factors has influence on micelles size and makes them smaller in an emulsion? 

Which factors? Basically everything you add to an emulsion, how/when you add them, and how you process it.

What makes them smaller? Besides everything (which can also make them bigger or longer and any whatever form), the main factor which makes them small is energy. This may come from high sheer or pressure, ultrasound… Lower energy strategies involve PIT and PIC emulsification.

Where to start? Stevenabbott.co.uk is nice and free lecture with tons of useful information (if you’re willing to go into detail and sciency stuff). It’s not a guide on ingredients and doesn’t give you formulations, but tools .

Thanks a lot

[Abdullah]

Do you also make cleansing Products? 

What anionic surfactants do you use?
