Do you have a professional pH probe that shows pH in decimal point? Please don’t touch acids until you buy it. I am not trying to be dramatic, you will hurt yourself. pH stripes are not accurate. Also pH can change after the product is made and you need a lot of knowledge to formulate with acids.

No, you don’t need heat CAPB and Decyl Glucoside. It all depends on the surfactant you use. Also don’t be surprised if you don’t really like that shampoo. Glycosides are draggy. Do some reading on surfactants. Makingskincare, swiftcraftymonkey, itsallinmyhands have good information on surfactants. You need to figure out active surfactant matter to make sure you don’t use more than 15% for shampoo

@Bubbles this is a discussion you are referring to https://chemistscorner.com/cosmeticsciencetalk/discussion/4817/raw-material-first-cosmetic-product-assurance-for-industry-novice-to-not-go-wrong-way
If I understand it right, clay contain so much of metal ions that EDTA will be overwhelmed by it. Too much of EDTA would be required to bind all these ions.

Two questions: 1)have you tried it yourself 2) Is the liquid transparent or cloudy? I tried to incorporate 1% of tocopheryl acetate to a serum. It took 4:1 of PEG-40 HCO (which is much better solubilizer than poly 80) to achieve clear liquid

If you want a simple answer - Magnesium Ascorbyl Phosphate. Because MAP and Niacinamide require similar pH (6-7) and both are water soluble. Would this combination really remove spots? I highly doubt it. There two great podcasts on the Beautybrains - about vitamin C derivatives and skin brightening.

I don’t use it for making products. Only for testing new material or running formulas for the first time. It’s strong enough to mix many polymers that would require stick blender otherwise, but this machine isn’t fast. It’s main advantage is that it helps not to waste materials.

Your formula should be for 100% not for 100 gr. Use MS Excel.

2,000 x 20% = 400.

It should be a good one. I worked with another crosslinked polymer (same inci as ultrez 21). Make sure you let it hydrate before neutralising or you will end up with lumps. Leave it and don’t stirr, it doesn’t like high shear. Skip sodium gluconate, it might affect viscocity. Add TEA by drop (literally one drop, mix check pH, one more drop etc) and check pH until you are around 7 and it will thicken. Also you will get high viscocity at 0.5%. Try on water first.

Anchor blade is kinda foolproof.

@Microformulation, cosmetic consultant should be in top 10 most stressful jobs.

And try not to make batches smaller than 100gr. Because it’s difficult to achieve precise measurements.

@Sibech, this one is in my top 10 of obnoxious claims:
https://www.beautypedia.com/products/cellular-eye-make-up-remover/?archive_search=%2F%3Fs%3DEye%2BMake-Up%2BRemover
“Cellular” makeup-remover made of cellular cyclomethicone, cellular esters, cellular water and cellular parabens (it’s duo-phased). 60 GPB in the UK. Because it’s “cellular”… -
This water is so magical that it emulsifies oil and colors it without help of “chemicals”

You can get a precise scale for jewelry (200 gr) on Amazon for less than $10. Even if you are a home crafter and have no intention to sell you need a proper scale. Spoons, cups, drops aren’t serious.

You need triethanolamine (TEA) to neutralize carbomer. It is not expensive, easily accessible and easy to use. You can also use NaOH, but unless you are making soap and have it on hand I don’t recommend buying it. There are many types of carbomer, some of which do not need neutralization. Ask your supplier what they have. But any carbomer is better than xantham gum. Carbomer makes clear and bouncy gels.
-
@luiscuevasii, you can use ceteareth 20 as an emulsifier for a conditioner. It’s non-ionic, and compatible with cationic ingredients. However, you might not like the draggy feel of stearic acid. Consider cetearyl alcohol instead. I would replace mineral oil by silicones. And please post full formula with percentages.
-
It looks ok overall. The only thing I would recommend, if you can find carbomer use it instead of xantham gum. If you don’t have carbomer, try 0.5% of xantham first. If too runny, make it 1. 2% sounds like too much.
-
It’s hard to preserve. You need a good preservative.
-
It’s all about wording. Say it’s made ‘with’ natural ingredients. Water is at the end of the day a ‘natural’ ingredient and you definitely use water, so it’s made ‘with’. I saw a bunch of ‘natural’ cosmetics that use phenoxyethanol. Another example, we all know that famous British brand that doesn’t test on animals. They ask you to sigh a petition and have a cute bunny picture in every store. Is their claim true? Yes. They do not test on animals. Reason? Ingredients that they use (butylene glycol) have already been tested long time ago. They don’t need to apply their generic lotions on rabbits. Use the same logic.

Thank you @Sibech. I know last two. I will have a look.
-
Thank you @Doreen. It is a very interesting statistics. All my friends are saying that my product “would be amazing if not the smell”. I had a slightly different impression, as Dior and Chanel are heavily fragranced (Dior moisturisers smell like “Dior”).
Makingcosmetics do sell some limited number of fragrances. I tried gracefruit but was not very happy with the quality. I will try Brambleberry. -
You need CAPB. Shampoos always have several surfactants. CAPB will make it more gentle.

Amino acids are building blocks of proteins, so they are much smaller. These all are claim ingredients. You can use it as a selling point but be careful promises. You can say that you are using a complex of amino acids that “penetrate” to hair but don’t say they do anything that you can’t prove.
