What preservative are you using?

You may replace it with more CAPB or APG c MEA

[Abdullah]

They also chelate calcium from protective cells of bacteria so preservative can kill them easily. 

[Abdullah]

@PhilGeis @Lab thanks 

My point was to saa what preservatives were used on those contaminated products. 

[Abdullah]

Yes it is completely safe. 

What are the ingredients?

@ShawnL9022 no i haven’t tried that. 

What is the lowest pH it which Stearic Acid + Sodium Hydroxide can be stable? 

What is the pH range you are trying to reach? In a range of pH < 6.0, this combo will stay in acid form. For a specific reason, if you need to add a negative charge to your emailsion.  You can replace GMS with GMSE (Glyceryl Stearate SE), then remove Polyglyceryl-10 laurate. That can help increase viscosity, either. 

I work in pH 5 or below

[Abdullah]

@ShawnL9022 no i haven’t tried that.

[Abdullah]

For preservative use DMDM hydantoin. Inexpensive and effective

[Abdullah]

They may also have airless package to helps preservation

I’d replace coco sulfate (it’s very similar to lauryl sulfate). Try a more ethoxylated surfactant, like sodium laureth-3 sulfate (or higher).

@ketchito - Thank you for the suggestion. I purchased SCS because it was cheaper than SLS and SLES and I thought it would function similarly.

Can you explain more about why you don’t recommend it?

Because usually it is more expensive and harsher. If it is less expensive then use it. No problem. 

It was just suggestions

[Abdullah]

@ketchito i tried to make a lotion according to this advise. 

As my English is not so good maybe i didn’t understand this correctly. 

Please let me know what do you understand from this and what was my mistake. 

[Abdullah]

@ketchito i will tag you in another post. Please have a look and let me know what do understand from it. 

[Abdullah]

No

[Abdullah]

If this is your first formulating, you have 3 options.
 
1. take a course to learn properly and then formulate according to what you have learned.

2. Purchase a formula that work from a chemist that knows.

3. be prepared to make tens or hundreds of wrong samples until you make a stable or good product.

When i started, i searched Google for best ingredients for a Shampoo, then searched for formulas with those ingredients, then purchased those ingredients in bulk because i had to import them from another country and i was starting business too.
When i received them and made the product, it was the worst formula and those ingredients wore the worst ingredients too. 
So don’t trust google.

About your formula, i don’t know about transparent lotions but your IPBC and HA is too high, you will need more and stronger emulsifier, your will need citric acid and sodium hydroxide to adjust pH and a pH meter to check your pH.
 

[Abdullah]

Can you explain what does “Coconut oil is rated very high in salicylates” mean?

I what to know too. 

[Abdullah]

What will be the ph?

[Abdullah]

What percentage of sci and total Surfactants do you use?

It is said that it loses its activity over time at pH below 6

[Abdullah]

Yes because of sci. 

I am not sure about its stability, internet and suppliers say different things. 

Maybe @Perry or another expert comment what is correct.

[Abdullah]

Use sodium chloride.

When finished these ingredients 

Use SLES instead of coco sulfate

Use cationic guar instead of pq10 

It is about equal but much more expensive without any benefit in shampoo. 

[Abdullah]

I would reduce pq10, HPMC and and sodium phytate to 0.1% each.
use EDTA instead of sodium phytate and CAPB instead of shea betaine.

pH 6

What is the active percentage of each surfactant? 

[Abdullah]

I understand that both ethanol and isopropyl alcohol have much lower surface tension than water and break foam bubbles. But I only tried it with isopropyl alcohol because that’s what I have

Thanks 

Fortunately it was just foam

[Abdullah]

ketchito said:

@Abdullah Usually oils from cleansers deposit through a mechanism called “assisted deposition”, but that can only happen in the presence of cationic polymers (except silicones, in which there are other factors that make them deposit, like a change in entrophy, or charge in the case of amodimethicones…although, cationic polymers still can aid in their deposition). 

Thanks 
Is there any ratio that for example for 1% GMO in a formula, what percentage of cationic polymer like pq10 is required?

[Abdullah]

What type of help do you need? 

Or you need a complete formula?

[Abdullah]

@Camel how does it compare to alpha arbutin 2%? 

I recently launched a 2% alpha arbutin at pH 5 serum for skin whitening and age spot. 

I am not using it myself as i don’t want to be white  but people who are using it haven’t noticed any effect of it since about a month or so use.

Maybe it takes more time to function or it is not effective at all. I don’t know. 

[Abdullah]

What are CSA, MPG and sepi white? 

I would say add chelating agent, reduce Propyl paraben and add a preservative for bacteria

I am a maximalist and not ashamed of it Although I don’t use any extracts and natural fluff but I add several rheology modifies and esters to achieve certain aesthetics that no one but me would even notice in a blind test. But hey, I am not a chemist

I think this is not called maximalist. You are using each ingredient for a purpose and you are able to see the result. Without all those ingredients you don’t get the results that you get with all those ingredients. 

maximalist uses ingredients that he doesn’t know what is the benefit of adding it over not adding it. 

Usually everyone uneducated or new are maximalist. They do a Google search, read about the benefits of 30 ingredients, believe all those information is true, and now want to combine all those benefits in one product.
That is how i was.
