Professional Chemist / FormulatorJuly 23, 2025 at 12:26 pm in reply to: AI Friend or Foe to the Cosmetic chemist?Thanks guys! Hopefully, you get a chance to tune in.
I’m taking the “it’s great” side but that is not exactly how I feel about the topic. I do see the real problems with it.
I will add however, in my testing it has produced some surprisingly good starting formulas. But you do have to steer it away from it’s terrible suggestions for preservation.

Professional Chemist / FormulatorJuly 23, 2025 at 12:17 pm in reply to: 0.05% Fragrance in productsWell, for some consumers ANY ingredient in your formula could cause sensitivity. It’s just that there are more ingredients in the fragrance that could cause the problem for more consumers. But it is generally true that the lower you go in fragrance, the less exposure people get, and the less chance that they will experience a problem.

Professional Chemist / FormulatorJuly 8, 2025 at 10:27 am in reply to: MoCRA - any further updates?Yes it is happening. Some of the stuff has already been implemented.
What’s in Effect (and has been actively happening):
-
Adverse Event Reporting: Companies have been required to report serious adverse events associated with their cosmetic products to the FDA since December 29, 2023.
-
Facility Registration and Product Listing: Cosmetic manufacturing facilities were generally required to register with the FDA by July 1, 2024. Companies also had to list their cosmetic products, including ingredients, with the FDA by December 29, 2023, for existing products. The FDA has reported a significant increase in registrations and listings compared to the previous voluntary program, indicating widespread industry compliance with these mandatory requirements.
-
Safety Substantiation: Companies must have records to support the safety of their cosmetic products.
-
Mandatory Recall Authority: The FDA now has the authority to issue mandatory recalls for unsafe cosmetic products.
-
Professional Use Labeling: Specific labeling requirements for cosmetic products intended for professional use became effective.
And some of the stuff has been delayed…
Where There Are Delays (and the FDA is behind schedule):
-
Good Manufacturing Practices (GMPs): The FDA is mandated to establish federal regulations for GMPs for cosmetic facilities. A proposed rule for GMPs is now anticipated by October 2025, which is later than originally envisioned.
-
Fragrance Allergen Labeling: Rules requiring the disclosure of certain fragrance allergens on cosmetic labels are still in development, with a proposed rule expected by January 2025 (a pushed-back timeline).
-
Talc Testing for Asbestos: The FDA is mandated to establish standardized testing methods for detecting asbestos in talc-containing cosmetic products. A proposed rule for this is anticipated by December 2024, also a revised timeline.
In summary, MoCRA is very much happening, and companies are complying with the implemented requirements. However, the FDA is behind schedule on developing some of the more detailed new regulations mandated by the Act. The “DOGE cuts” and broader efforts to reduce federal staffing and regulations are likely contributing factors to these delays, as they impact the FDA’s capacity and prioritization of its many responsibilities.

This time they got the Big Guys involved.
Inevitable. Clean beauty / EcoBeauty / Natural…. None of this is an ownable position for a brand. If it gets popular, the big guys will just adopt it, adjust it so it fits with what they were already doing, and declare victory.
I just wonder what the small guys will vilify now?

New name for a thing that has been around for decades. Any ingredient derived from a plant or animal can be called “biocosmetic”.
This reminds me of renaming surfactant solution as micellar water.

Professional Chemist / FormulatorMay 16, 2025 at 12:48 pm in reply to: Korean Rice Peel FormulationWhat are the ingredients?
You’ll likely get better/more responses if you include the list of ingredients. But yes, it’s possible to replicate any product on the market. Also, no you don’t have to include all 42 ingredients to do it.

Professional Chemist / FormulatorMay 16, 2025 at 12:20 pm in reply to: BANNED ALOEVERA COMBINATION PRODUCTS.In the US, there aren’t really bans on ingredients except things that have been proven to cause harm. I know this is true in the EU too but they also will ban ingredients that “might” cause harm.

Professional Chemist / FormulatorMay 16, 2025 at 6:56 am in reply to: The death of my brand - Indochine NaturalWhat were the lessons you learned (besides don’t hire someone who will drive your business out of business)?
What kind of bad marketing decisions did they make?
Presumably, they thought they were making good decisions.
Did you have the power to approve what they were doing with your brand?

Professional Chemist / FormulatorMay 7, 2025 at 10:26 am in reply to: Guidance on Ingredient Registration and SDS RequirementsI’ll answer some of this (other stuff I don’t know). If you have an INCI and CAS number you should be able to market the ingredients. However, you’ll also need to have evidence that the ingredients are safe for use in cosmetics. Some testing or report or something.

So yes, it will change the pH of a water based system. It will definitely lower the pH of something higher than pH 6

When you say “split” I’m assuming you mean it separated? 1.6% EO is very high so that is likely your problem. Also, I think Allantoin can contribute to separation.
If you were selling the product you should probably throw it away. If you are using it yourself, just Shake before use and it should be fine. Unless, of course you have some microbial contamination. Then you should just throw it away.

You can tell these companies aren’t really sincere in their efforts. If they were, they could reduce their carbon footprint or environmental impact very easily.
Just stop selling so much and stop trying to sell more and more every year!
But sustainability and capitalism don’t really mesh.

Yeah, everyone “steals” from everyone else. If you are a small brand and are doing well, a big company wouldn’t hesitate to take your idea and try to make it bigger. Or if the idea is too hard to copy, they’ll just buy your company. This shouldn’t be surprising.

Professional Chemist / FormulatorJune 5, 2025 at 2:24 pm in reply to: Use of food grade ingredients in cosmeticsYou have to be able to prove that your products are safe. If you do not have paperwork, how would you be able to verify safety? Even if you use food ingredients you’ll need proper documentation to prove your products are safe.

Professional Chemist / FormulatorApril 21, 2025 at 7:33 am in reply to: Most well tolerated fragrancesRespectfully, a hard disagree. Natural compounds are much more likely to cause allergic reactions than synthetics.

Yeah, the GHPC is probably fine. It’s also possible that your PQ7 is a little high 0.6%. Typically, 0.2% is enough. I don’t know the nature of your separation but 1/4 the volume seems pretty high. This usually means an oil but it could also mean a polymer, like PQ7. It’s water soluble so it shouldn’t be a problem but you never know with these things.

Professional Chemist / FormulatorApril 17, 2025 at 7:46 am in reply to: chatGPT vs deepseek answer much different for same question about same questionI agree. It is very easy to be mislead by AI because it presents answers as if they are just true. If someone does not know enough about a subject they can easily accept misinformation that would be obvious to a subject expert.
