This is big news in the cosmetic industry. Good to see. Although if the FDA started banning ingredients that weren’t proven to be functional, there would be a lot of anti-aging ingredients that couldn’t be used.

@chickenskin - yes, parabens are perfectly safe for use in cosmetic products. Since they’ve been used for so many years and have decades of safety data behind them, I would say they are more safe than most of the “natural” alternatives.
@spicykimchi - your choice depends on what you consider to be “natural.” Some people consider parabens to be natural since they naturally occur in plants.

Methylparaben, DMDM Hydantoin, Kathon

If Aloe is used for marketing, 5% is excessive. You could go 1% or less.

@Bobzchemist is right. The list of unacceptable ingredients was not arrived at through any scientific evaluation of data. They didn’t really even have cosmetic scientists involved in making the list.
The most simple answer to why Behentrimonium Chloride is acceptable is because it was already present in their house brand and they didn’t want to reformulate.

Hello
It looks like they have an event coming up on September 20 then another on October 10. http://www.ctscc.org/events/The NYSCC is also very active. https://nyscc.org/
My suggestion would be to attend one of these events and meet some people involved. You may even consider doing some volunteer work for the chapter. You can probably join as a student member for your first year.

Have you got involved with your local Society of Cosmetic Chemists chapter? Where are you located?
-
Yeah, that’s a problem with HEC as a gel base. Carbomer just works best. Instead of using cationic conditioners, just use other conditioning ingredients like humectants.
-
Do you have an example product you are trying to emulate? It would help if you had an ingredient list.
-
We were always required to use pen also. I started in the industry in 1992
-
That’s a good way to prove it to yourself.
-
I agree with @Belassi - I’m guessing a reaction with the Benzalkonium Chloride and the metal in the pot.

These are magnetic facial masks. Yes, they put iron in them.
Ingredients: Iron Powder, Cyclopentasiloxane, Isopropyl Palmitate, Dimethicone, Butylene Glycol, Cyclomethicone, Caprylic/Capric Triglyceride, Glycerin, Olea Europaea (Olive) Fruit Oil, Simmondsia Chinensis (Jojoba) Seed Oil, Prunus Amygdalus Dulcis (Sweet Almond) Oil, Sea Silt Extract, Fragrance, Rosa Canina Fruit Oil, Borago Officinalis Seed Oil, Oenothera Biennis (Evening Primrose) Oil, Chamomilla Recutita (Matricaria) Flower Oil, Lavandula Angustifolia (Lavender) Oil, Pogostemon Cablin Oil. -
Yes, humectants pretty much rinse away when used in rinse-off products. They can have an impact on the way the product feels in hair and maybe impact the foam, but as far as hair goes, it just rinses away. They are better for leave-in products.
I don’t think all formulators will agree with me and hydrolyzed proteins have been used in hair care products for decades. However, I haven’t seen evidence that they do anything noticeable when delivered from a shampoo. There is also no good mechanism by which they would stay on the hair from a shampoo since they aren’t charged. It’s possible the protein could absorb onto the surface of hair but there is little practical evidence for that.
In a conditioner which stays on the hair longer and does not have surfactants to easily rinse away the hydrolyzed protein, it may stay behind on the hair better in which case it will act as a humectant. Protein does not really strengthen hair when applied topically. The thing that gives hair strength is the structure of hair protein. Just glopping hydrolyzed protein on top of a structured protein fiber like hair isn’t going to do much. Think of it like this. If you had a cotton shirt that had a hole in it, could you just dump more cotton on the surface of the shirt and expect the hole to be repaired?
The talk of protein on hair (the kind doesn’t matter because it’s all hydrolyzed so essentially the same) is just marketing fluff.

Of course it depends on the other things in the formula but here’s my comments.
1. Hydrolyzed proteins - not doing much except maybe some moisturizing. They are water soluble which means mostly, they get rinsed away & have very little effect.
2. Aloe vera juice - not doing anything. It’s water soluble and gets washed away.
3. Honeyquat - some light conditioning. You may (or may not) notice any difference.
4. Polyquat 7 - some conditioning. If you have polyquat 7, you’re even less likely to notice anything from the honeyquat
5. Glycerin - it just washes away. It will help prevent crusting of your formula if it is delivered from a pump. But it’s not having any effect on your hair.
6. Shea butter - It’s reducing foam and the cleansing effectiveness of your surfactants. You might get some “conditioning” from it but it’s conditioning in that it is not cleaning your hair.
For cleansing products shea butter does not make much difference. For conditioning products (after shampooing) things like coconut oil and shea butter can have an emollient effect changing the feel of hair.
Coconut oil is the only oil that is proven to penetrate hair so if any matters, that would be the one I use. Just not from a shampoo because it just gets washed away.
-
@PharmaSpain - That’s a pretty good idea.
-
I would check your premises.
While you see parabens in the news, before changing from a safe preservative system to one that is not tested, you should check with your consumers (and potential consumers) to see if they even care about parabens or are even aware of what they are.
-
Mix the agar / xanthan gum longer.
The oils may be separating too.

Methylparaben
DMDM Hydantoin -
The problem problem isn’t your ingredients, it’s the way you are mixing them together. To make most color cosmetics you need a device that will efficiently & effectively grind the products and colors together. You can’t simply just mix them in by hand.
-
Oh my. shakes head, walks away.

The 1300 ingredient restriction doesn’t mean that EU products are more safe. Uranium is not banned from cosmetics but putting it on a list of banned ingredients won’t do anything to improve cosmetic product safety.
You have to look at what those 1300 ingredients are. The vast majority wouldn’t be used in cosmetics anyway.
-
There are a couple of possible explanations.
1. They are uninformed and do not realize they need preservatives in order to sell safe products. (They probably don’t even test their products).
2. They use preservatives but just don’t put them on the label.
If you’re a small company, cheating on your labeling is not likely to be found out unless someone reports you. Even then the FDA has limited resources & can’t get to everyone. It’s like cheating on your taxes. It’s illegal but people do it & get away with it.
It’s a matter of personal ethics and risk. Some people are willing to take high risks and other people want to push their marketing story no matter what the truth is.
