Shampoo bar or other such solid form.

Minimum? You don’t really worry about how little one puts in, although it would likely be ineffective.2% and below Salicylic acid is fine. Greater than 2% makes it an OTC Drug under the Acne OTC Monograph.Lactic Acid doesn’t have an OTC limit but from experience I would follow the 10% AHA limit and the >3.5 pH recommendation. I know of a line that ignored this limit and faced a threatened lawsuit. In the lawsuit they cited the CIR limits, established the credibility of the CIR, and then alleged that the line ignored a credible guideline.

Anything above 2% is OTC so you have a hard limit with SA. 10% AHA with 2% BHA would be fine, but I would keep the pH >3.5.

Sunblock is not an accepted term.

Retinol with BHT/Polysorbate 20 OR Retinol with Tocopherol/Polysorbate 20 would be a strong possibility as well.

I agree with @MarkBroussard. I see SO many questions in the Forum which I know the answer to, but I don’t answer if I think they are looking for a quick solution rather than seeking to learn about the topic more in-depth.Also, in the past 3 months I have gotten so many (>30) in-box messages requesting free help. Please keep in mind that for most of us, this is work product.

You really need to read some of the Lubrizol Technical Guides on Carbomer. They are extremely helpful.

Without seeing your full Formulation it is difficult to weigh in with any confidence but I would imagine it comes down to electrolyte intolerance (which would direct you to proper grade selection), neutralization of the carbomer (requires a proper process), or even possibly a process issue unrelated..You do need to be patient as participation in this forum is voluntary and not a revenue stream for most Chemists. I also believe in the “give a man a fish approach” as a more universal study and reading not only would answer all these questions, but also grant you knowledge helpful in future Formulations. -
We had an issue with botyris with a CBD supplier I have worked with. In the end it came down to pruning, sanitation and the use of Biochar. It is best dealt with through farming methods.

What is keeping the 8% Glycerin (water soluble) from separating from your anhydrous product?

Abdullah said:People don’t care if it is SLS or sarcosinate. Look what does the shampoo that most people use have. SLS.
This mean most people don’t care about SLS.
Exactly. People get stuck in the minor details of the ingredients (“it has the word sulfate”). This is outdated and not significant in any real markets.
-
The shampoo is designed to remove oils, so it honestly will have little, if any real benefit.
-
DHA is very likely your culprit. Also, it reacts with some colorants.Formulate at a PH of 3-4. In water, DHA initially has a pH of 5.5 and which drifts down to 3-4 over time.

PolySugaMulse D9 from Colonial works great.
-
7% is a bit high and you may have some safety issues. You may want to check IFRA guidelines.
-
Are you using DHA as well in the tanning product?”

I agree with @PhilGeis entirely. You need to remember that the FDA Auditors likely have more experience in the Market, specialized training in Regulatory, and will quickly recognize the claim. They are not ignorant.As a rule of Thumb, if you believe your customers will make the leap on their own to “eyelash growth”, of course so will the FDA.
-
I have experience in producing the projects. I have also seen the FDA discipline letters. You may not make any eyelash growth claims whatsoever. Hair growth of any kind is a drug claim.There were several “Cosmetic” actives touted for this claim, but they have become much less common. Also, if you read their copy they usually say something like “volumizes” or “increases the appearance of.”

You are asking for an ingredient list and likely percentages. That would be a free Formulation. Many of the contributors are Professional Chemists who provide these services as a charge. As such you can’t expect “free” Formulas.Better questions are;
- What has you research into the Formulation led you to so far? You will need to “do your own homework.”
- What benefits do you wish the product to deliver?
- What have you tried already?

Bottles and containers aren’t sterilized. Cosmetic manufacturing is sanitary, not sterile. You are not working in an environment such as a laminar flow hood where you could maintain sterility.Packaging components should be stored in closed containers and inspected for gross contamination before use. They are generally sprayed down with 70% IPA and allowed to dry.Traditional tubes do require specialized equipment to seal. There are smaller systems but they as much slower than standard equipment. There are containers more properly called tottles which do not require heat sealing.

This really isn’t a Forum for free Formulas.

CB007 said:pH is around 6.5, viscosity ~10,000cps with TB@20rpm
No chelator- as requested by client
Cetyl Alcohol, Stearic Acid for emulsifiers…plus the Carbomer for water phase thickening. This is an old formula so maybe I need to re-assess the emulsification system completely…
The chelator is needed to augment the preservation system. You should never let the client compromise safety. If you stress it’s function they will generally relent.Perhaps they are saponifying the Stearic acid with the Sodium hydroxide to create a “soap.” However, if this is not the case, you do NOT have an emulsification system. -
Well, yes, I’m aware of that. But the studies linked above have found
other uses for it. It would be capable of denaturing hair keratin.I assure you, if it were feasible DSM would have already promoted it for its use.This is not research.
