Professional Chemist / FormulatorMay 8, 2024 at 12:48 pm in reply to: Understanding how to Formulate with SurfactantsAs to how much of a ratio you use between surfactants, that is just a matter of experimentation. You want to balance performance with gentleness and cost. The ratio / amount is different with different formulas.

Professional Chemist / FormulatorMay 8, 2024 at 12:45 pm in reply to: Large scale production bottles and jars treatmentTypically, the containers you get from the packaging supplier are already cleaned and washed so you don’t need to do anything to them. At least that is the case for large scale producers.

Most extracts are sold in Glycerin or Propylene Glycol. -

Professional Chemist / FormulatorMay 7, 2024 at 10:14 am in reply to: I’m from the government and am here to help you!!I’m confused.
Do they not think the cosmetic industry has already tried those compounds?
What do you see as the major problems with their study?
Also, to be fair, there are plenty of non-government, academic types who have published equally bad “research”

Professional Chemist / FormulatorApril 26, 2024 at 9:25 am in reply to: Max % at cool down phaseIt really depends on the formula / emulsification system. 10% might be fine for some systems.
In fact, we used to do what was called a “quench cooling” method with one of our hair conditioners. We would add 25% cold water after creating the emulsion. This rapidly cooled the system so instead of taking 8 hours to make a batch we could do it in 2 hours. And we didn’t have any stability problems in that formula. -

Professional Chemist / FormulatorApril 25, 2024 at 11:06 am in reply to: Question About Aveeno's Preservative SystemI agree that the Glycols are helping.
And with the Baby Daily Moisture cream, they also list 1.2% Dimethicone as the active ingredient. This is actually an OTC drug product ( https://www.aveeno.com/products/daily-moisture-baby-cream ) My guess is that it has a low enough water content that Water Activity is also helping with preservation. Also, it is in a pump which helps and produced in an OTC factory which is going to be cleaner than your typical Cosmetic manufacturing facility.

Professional Chemist / FormulatorApril 23, 2024 at 9:41 am in reply to: How to calculate ASM when making a shampoo/bodywash, etc.?You’re almost right! You’ve calculated correctly the amount need for 100g. If you want to make a 250g batch then you’ll need to multiply those numbers by 250/100 = 2.5.
SCI: 9.41g x 2.5 = 23.53g
Disodium cocoamphoacetate: 13.33g x 2.5 = 33.33g
Or if you wanted to make a 500g batch you would multiply those numbers by 500/100 = 5.

Professional Chemist / FormulatorApril 19, 2024 at 10:00 am in reply to: Are clarifying shampoos worth the money?These are really just marketing terms. When I was working on a shampoo project and our marketing people wanted a “clarifying” version of our shampoo, we simply increased the surfactant level by 1%. Change color, packaging, and viola! You’ve got a clarifying shampoo.

Professional Chemist / FormulatorApril 10, 2024 at 8:18 am in reply to: Are products with Minoxdil always considered an OTC?Agree with @Microformulation - Minoxidil is a drug whether you make claims about it or not. You need to be certified to make products with it.

Professional Chemist / FormulatorApril 9, 2024 at 7:27 pm in reply to: Need help making shampoo cushionyTo get closer to a “store-bought” product, you first have to get rid of the ingredients that are either doing nothing or actively making your product worse. Remover (or reduce to <1%) the following….
Glycerin, Bamboo Liquid Extract, Date Palm Liquid Extract, Honeyquat, Panthenol Powder, Vegekeratin Hydrolyzed Protein.
Make that formula first and then see how your needs to be improved. With the exception of Glycerin, the ingredients I listed above are what we call “claims” ingredients. They are just put in formulas (especially shampoos) to give the marketing people something to talk about. They don’t actually work to do anything in the formula.
You don’t include Glycerin because it depresses foam and provides no real benefit to a shampoo.

Professional Chemist / FormulatorApril 6, 2024 at 2:52 pm in reply to: How do I use liquid carbomer to thicken my product?Well one thing is that Carbomer doesn’t work very well with electrolytes like sodium benzoate. Also, you should neutralize Carbomer at the end, not at the start.

Professional Chemist / FormulatorApril 2, 2024 at 10:04 am in reply to: pH 10-11 clarifying shampooI don’t think making a shampoo at pH 10 or 11 is a good idea.
There is no benefit to it and you might harm someone who uses it.
Keep the pH at around 5.0 and also add some preservative! -

Professional Chemist / FormulatorMarch 17, 2024 at 2:22 pm in reply to: Instability in 2 in 1 shampooThey didn’t give you an ingredient list? It seems pretty pointless without it.
I guess they want you to add some HPMC (cellulose polymer). That could help with viscosity, stability & foam.

Professional Chemist / FormulatorMay 10, 2024 at 10:04 am in reply to: Which is best as a leave in conditioner?This is an old discussion! But I say PQ-37 is better for leave in because you need to use less of it to get a reasonable effect. You could use 0.2% of PQ-37 that would give you the same effect as say 2% BTMS. So, this would result in hair that feels less weighed down.

Professional Chemist / FormulatorApril 22, 2024 at 2:23 pm in reply to: Need help making shampoo cushionyMost shampoos don’t use a thickener like Crothix. Better would be something like Hydroxypropyl Methylcellulose. That helps with foam. Or you can just use Salt to thicken and use a cationic polymer like Guar Hydroxypropyldimonium Chloride for foam stabilization and conditioning.

Professional Chemist / FormulatorApril 9, 2024 at 2:56 pm in reply to: All Natural Patchouli Lavender Face WashYou’re arguing something different than my point. My point is that saponification is not more natural than the process used to make SLES. In your way of looking at it, I would agree there are less steps, but that doesn’t make it more “natural”. It is still a man-made process that requires synthetic chemistry that isn’t produced in nature. They are both synthetic compounds.
I also disagree with your assessment of the safety of the ingredient and will defer to toxicologist opinions.

Professional Chemist / FormulatorApril 6, 2024 at 9:38 pm in reply to: Preserving room spray (preservative vs. alcohol)There are lots of people who ride around in cars without seatbelts and never get hurt. That doesn’t mean it’s a good idea.

It’s not that the corporation necessarily imposes their ethos on the bought company, usually what happens is that the small company wasn’t following all the appropriate regulations & rules of the industry so formulas, claims and packaging usually have to be updated. Then companies look to reduce costs by getting economy of scale so formulas are often optimized.

Professional Chemist / FormulatorMarch 18, 2024 at 7:20 am in reply to: What innovations will be the game changer?No.
Sensitive skin is a term that is not really well defined. And targeting babies is especially problematic when trying to make consumer-noticeable differences. Because babies can’t really tell you if something is working better or not. You’re left with parental observation which is just not reliable for subtle changes.
