While anionics are certainly the most effective when it comes to removing oils, I wouldn’t necessarily say that other surfactants don’t clean properly. I think you can achieve cleansers with amphoterics and nonionics that will be sufficient for majority of the population when it comes to cleanliness.
They clean different soils and differently.
So they can be more drying but still dont clean properly.
By proper clean i mean after some times you can feel it that your hair is not being cleaned no matter how many times you wash it.

Pseudomonas aeruginosa can produce green color.
What is your pH and ingredients?

Perry said:@Abdullah - It wouldn’t be surprising that there was a recall even with a product that had a robust preservative system like you described. Cosmetics are not designed to be aseptic so even the best preservative system can fail. I would say most of the cause of recalls is due to inadequately clean manufacturing facilities.
I’d add that since a greater number of cosmetics that are produced use a good preservative system, you would expect more instances of recalls with good preservative systems than with bad.
Thanks

@Perry i did so. The problem is that when we search about ingredients of a recalled product in Google, it shows ingredients that they are currently using that may definitely be different and improved from the contaminated batch.
I search ingredients of a recalled contaminated product and it had DMDM hydantoin, methyl & Propyl Paraben and EDTA in results from Google search.

1: These ingredients are expensive. Each of these these ingredients can solve your problem alone. so why use all of them together and increase the cost and chance of adverse effect?
2: these are hard to work with, solubilize and stabilize alone in a product. Mixing them will be harder.
3. Using These will benefit you only if you have the problem. When the problem is solved, it is useless and waist of money.

@Microformulation can you explain this please.
Does 40g/L mean in 1 litter water mix 40g allantoin or in 960ml water add 40g allantoin that becomes 1L?

Karo_lina said:Abdullah said:Yes it is completely safe.
What are the ingredients?
so, won’t you have irritated and reddened skin after using a cosmetic with a pH of 3.5, twice a day for half a year?
That depends on ingredients that you are using but suppose your ingredients work the same in each pH, a product with pH 3.5 will be better than 5.5

Citric acid is also completely skin friendly. But lactic acid has extra benefits like exfoliation and skin hydration.
Citric acid creates problems with cationic ingredients
-
What preservative are you using?
You may replace it with more CAPB or APG c MEA
-
They also chelate calcium from protective cells of bacteria so preservative can kill them easily.

ShawnL9022 said:Abdullah said:@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

For preservative use DMDM hydantoin. Inexpensive and effective
-
They may also have airless package to helps preservation

Camel said:ketchito said: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

@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.

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

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.

Can you explain what does “Coconut oil is rated very high in salicylates” mean?
I what to know too.

What will be the ph?

What percentage of sci and total Surfactants do you use?
It is said that it loses its activity over time at pH below 6
