The limitation is in terms of % active ingredient. So if the limit is 0.25% in your formula and you have a 30% solution, the max you could use of your solution is about 0.8%
-
There’s also a safety leave-on limit for CETAC. If I recall correctly 0.25%

lol! The product is out of this world!

The decision to add silicones (or any other conditioning ingredient) depends on the performance characteristics you are looking for. If you want a light conditioning effect you might add cyclomethicone but if you want more conditioning you could add dimethicone. However, if you don’t want to add silicones you might not have to either.

Interesting. I saw these guys at their booth at the California SCC suppliers day. Despite the investigations it looks like they are continuing to offer their services.

As an aside, that residue trick (combining a cationic with an anionic) was the bases for how VO5 Hot Oil treatment works. You put the cationic material on your hair first, then use an anionic shampoo to wash it out. Viola, instant conditioning. At least that was the theory.

I’m sorry if that came off as scolding. It wasn’t meant that way. Text is not the most efficient way to communicate.
I certainly agree with your point that cosmetics are much safer and better tested than many other products. It still baffles me how the food supplement industry gets away with what they do.
-
@mikethair - I agree. There is so much work to do to market your own brand that worrying about competitor’s is not productive. The key is to find your audience, make products for them, make them love you, and what your competition does is irrelevant.
-
40% is definitely too high. Your suggested formulas seems reasonable.
-
“Even if it’s currently the best product I don’t understand why it hasn’t been tested more thoroughly by states.“
What has led you to the impression that the product hasn’t been thoroughly safety tested? What studies should be done that isn’t done?
More importantly, how are the claims you’re making about Glyphosate any different from the claims fearmongers make about cosmetics?
Cosmetic fearmongers claim the Cosmetic Lobby controls government regulators.
Cosmetic fearmongers claim cosmetics are causing cancer and haven’t been appropriately safety tested.
None of these claims are true.
As scientists, we need to stick to making claims that we can prove with evidence. Otherwise we risk becoming unreliable fearmongers.

@DAS - this is relevant. A review of the safety data related to glyphosate

@mikethair - The problem with only testing at RT is that you then don’t know whether your product is stable during shipping and storage conditions. If it separates at 45C that quickly, I wouldn’t consider the formula stable.
-
There seem to be lots of ‘chemical free’ claims here in the US. Particularly in the sunscreen area.
-
@Bill_Toge - And I bet those customers push back on you saying something like “But this company makes that claim, why can’t we?”
-
We always did a PET at the start of a stability test and on 45C, 8wk samples.
-
You can read all about it here.
“In one unpublished study cited in the review by the Soap and Detergent
Association (Arthur D. Little, Inc. 1993), 1 and 2% concentrations
of AOS were nonirritating after 24-hour patch testing. In another study,
1 and 5% AOS were mild irritants, with reactions ranging from erythema
to fissure formation accompanied by scaling.” -
Witch Hazel is not soluble in water so it isn’t much of an emulsifier for oil and water systems.
-
@Biochemist - No. There is not a linear relationship. In fact, the 45C for 8 weeks predicting RT for a year is just a guideline for many formulas. It only gives you a probability of having a stable formula. It doesn’t guarantee it. For any new formula, you still have to have a sample that goes out to 1 year at RT to see if the 45C sample at 8 weeks is predictive.
There is no shortcut to stability testing.

@ElenaZaharevich - 1,4 dioxane is a known ingredient and it’s safety profile has been evaluated. We know what levels are safe and the levels you get in cosmetics are safe.
When you avoid products and switch to alternatives, you expose yourself to ingredients with unknown safety profiles. Suppose down the line someone finds that something like Decyl Glucoside contains a previously unknown carcinogen. You’ve now exposed yourself to a different carcinogen.
It is not enough to identify potential carcinogens. You also have to know the levels of exposure that matter. Everything is a potential carcinogen. Dose matters.

Interesting. On a slightly related note I think I heard that SC Johnson bought Mother Dirt. It will be interesting to see whether a big corporation can sell a product like that.

Using clever marketing, “retinol complex” could be anything you want.
-
For you, when putting together your ingredient list you just use the term “fragrance”
In addition to the trade secret issue, the main reason companies don’t list fragrance ingredients is because that would make ingredient lists too long. Fragrances are composed of dozens or even hundreds of ingredients.
-
I’m not sure. I’ve not compared ws Shea Butter with PEG-75 Lanolin. They are both blends of lipid materials with similar chain lengths so they might work the same, or maybe not. You have to compare to know for sure.
-
The ingredients you need for the formula to make it just like that one are:
Water
Cocamidopropyl Betaine
Glycerin
Coco-Betaine
PEG-75 Lanolin
PEG-40 Hydrogenated Castor Oil
Hydroxyethylcellulose
Fragrance (Parfum)
PEG-7 Glyceryl Cocoate
Polyquaternium-10
Propylene Glycol
Polyquaternium-7
Aminomethyl Propanol
Diazolidinyl Urea
Iodopropynyl Butylcarbamate
But you could get close with something like this…Water
Cocamidopropyl Betaine
Coco-Betaine
PEG-75 Lanolin
PEG-40 Hydrogenated Castor Oil
Hydroxyethylcellulose
Fragrance (Parfum)
Polyquaternium-10
Aminomethyl Propanol
(Preservative of your choice) -
This is the problem with extracts and other natural ingredients. Two extracts might have the same name but be chemically different. It’s very difficult to have good quality control.
