Professional Chemist / FormulatorMarch 19, 2025 at 1:43 pm in reply to: Sharing any knowledge about emulsionI’ve been doing some reading on the use of HLD (Hydrophilic Lipophilic Difference) instead of HLB. I’m about halfway through the book and it points out the flaws of HLB and how HLD could be used to fill in the gaps if you have the right information. Even if you don’t have the information to plug into HLD, the theory in the book is useful and would answer some of your questions.

Professional Chemist / FormulatorMarch 12, 2025 at 8:37 am in reply to: Best preservatives for eczema prone skinI was looking into the same issue a few years ago. @MarkBroussard commented on my post advocating for Euxyl PE 9010. He used it in an eczema suite and it was the best tolerated option. As others mentioned in the post, it isn’t enough on its own to be considered a broad spectrum preservative and should be accompanied by a chelator and something to target fungi.

Does anyone have experience with Colloidal Oatmeal Lotion formulation for eczema? - Chemists Corner

Professional Chemist / FormulatorMarch 12, 2025 at 7:15 am in reply to: Frankinscense Hydrosol and witch hazel for EczemaI agree with @ketchito, focus on what the FDA has approved for use as skin protectants and work your way from there. This is what they consider skin protectant actives:
https://www.ecfr.gov/current/title-21/chapter-I/subchapter-D/part-347/subpart-B/section-347.10
I also have eczema and found that a generous amount of skin protectants, humectants, and occlusive agents worked best for me. I looked into making a two part treatment a while ago but have settled on only using the colloidal oatmeal moisturizer (linked below). It has greatly reduced the frequency and duration of my flare ups. If you have any questions about the formula feel free to pm me.

Professional Chemist / FormulatorDecember 18, 2024 at 10:52 am in reply to: Hair conditionerHi, it looks like you’re missing an emulsifier here. Your fatty alcohols can support an emulsion but they won’t cut it on their own. A pretty common one in conditioners is Glyceryl Stearate SE.

Professional Chemist / FormulatorApril 9, 2025 at 8:47 am in reply to: pH Adjusters & Incidental IngredientsI agree, I’ll send an email out so my objection is documented.
This is one of our larger clients who have around two dozen SKUs and millions of pieces/year. They can afford some new labels.

Professional Chemist / FormulatorApril 9, 2025 at 7:19 am in reply to: pH Adjusters & Incidental IngredientsThank you for the information. Now I know there are no loopholes to hide behind for EU markets. Unfortunately, this is being marketed in the US so they’ll be able to legally have their way.

Professional Chemist / FormulatorApril 9, 2025 at 7:15 am in reply to: pH Adjusters & Incidental IngredientsThat would be the most prudent course. But that would also be the more costly one since they’d have to get rid of their existing labels or place a label over the old ones.

Professional Chemist / FormulatorApril 9, 2025 at 7:08 am in reply to: pH Adjusters & Incidental IngredientsI’d also like to put it on the label, but it doesn’t seem like they’re going to go that route. All ingredients should be on the label in case someone wants to avoid citric acid for whatever reason (allergies, chemophobia, or esperidoeidiphobia)

Professional Chemist / FormulatorApril 8, 2025 at 3:11 pm in reply to: pH Adjusters & Incidental IngredientsI suppose if an ingredient is not considered functional it would fall under § 701.3 (L) (2) (iii) as a processing aid? I wouldn’t exactly call the level used insignificant (0.65%) but I can see it being called so.
“Substances that are added to a cosmetic during the processing of such cosmetic for their technical and functional effect in the processing but are present in the finished cosmetic at insignificant levels and do not have any technical or functional effect in that cosmetic.”

Professional Chemist / FormulatorApril 8, 2025 at 2:21 pm in reply to: pH Adjusters & Incidental IngredientsHi paprik,
Thank you for your time.
Why is pH adjusting not considered functional? Whereas adjusting the viscosity or clarity of a product is?
Do you know where I can find a source for not including pH adjusters in the LOI?

This formula is for personal use only and has remained pretty similar to what I posted earlier.

To answer your question I did not use it. I ended up taking @Abdullah‘s suggestion of phenoxyethanol + parabens + EDTA. I didn’t have any issue with this blend as far as sensitization or preservative failure.

Professional Chemist / FormulatorMarch 11, 2025 at 1:33 pm in reply to: Asking for help regarding a lotion-type serumI also premix certain gums with glycerin. I found that adding the premix in aliquots and mixing thoroughly in between helped reduce the amount of fisheyes or agglomerations I saw.
