No, I never was able to get a clear guar system. I think the long natural fibers in it make that difficult.

Also, preservation also depends on your manufacturing conditions. Without stability testing you can’t say something is going to have a 2 year shelf life.
-
Did you get a Certificate of Analysis or at least a Material Safety Data Sheet?
Without those things I would not assume the ingredient is safe.

@DAS - I remember having fish-eye blobs at the bottom of production tanks for gel formulas. Depending on how big the fish eye is, it could be heavy enough to fall to the bottom.

http://valdata.com for a professional thing.
You can get an excel sheet for figuring out formula costs here.

I agree with @DRBOB@VERDIENT.BIZ - the blob is most likely the Ultrez.

The FDA does govern cosmetics. They set the rules, do some inspections, and is the agency who goes after people who are not in compliance with cosmetic regulations.
However, the FDA does not certify cosmetics. They do certify colors used in cosmetics but not the finished product.
Topical is a term used by Amazon and as @Microformulation suggests, it’s not really an FDA regulated term.
Your claims might be a problem. You have to write them in a way that is truthful and that you can prove is true. For example, you can’t say “This product contains vitamin C and will lighten your skin”
There are a couple of problems with that claim
- skin lightening is a drug claim
- you attribute a function to to formula rather than the ingredient
So, you have to be thoughtful in how you write your claims.
I’m not really sure what Amazon considers a suitable COA.
-
It would help if you could provide the entire ingredient list.
-
Of course, if you do a stability test on a lab sample and it fails, you certainly wouldn’t want to proceed to production with that formula.
-
I’m still trying to understand what you mean by “stable.” And anyone who has used peptides in formulating can chime in.
What test would you run or characteristic would you recognize that lets you know whether the peptide is stable?
Short of doing x-ray crystallography, how would you tell whether your peptide has kept its conformation or has simply become a hydrolyzed protein?
Also, how can you tell whether the supplier has provided you an actual peptide or just a solution of amino acids in the right proportion of the peptide?
-
@ravimosai - I agree with @ozgirl that you shouldn’t mix acetic acid and ammonia.
But in general, your question is much too vague for anyone to give an answer. You provide much more information and ask a specific question that can be answered. Tell us…
1. Did you make this formula?
2. What were the results?
3. What aspect of the formula do you want to improve?
4. What is the formula doing that you don’t want it to do? or that you want it to do that it’s not doing?
5. What do you mean by “is the formulation alright”?If you want help, just putting up a formula and saying “give comments on how to improve it” is not an efficient way to go about it.

Interesting. I couldn’t find any safety data on that ingredient in the CIR (http://cir-safety.org/ingredients)
-
What do you mean by “stable”? That is, what test would you run or characteristic would you recognize that lets you know whether the peptide is stable?
If the peptide is simply added as a claims ingredient, it doesn’t really matter.

So you need a formula of water, ingredient X, and hydrogen peroxide.
To make 100 grams total (or 100%)
Hydrogen peroxide = 2.5%/33% = 7.57 g
Ingredient X = 10 g
Water = 82.43 g -
@Doreen - Indeed. The prospect of creating a consistent product with those raw materials would be daunting.
-
Does it have an INCI name? I couldn’t find one.
-
@Microformulation - I feel the same about the meme problem and wild claims. A cancer cure? Color me skeptical.
Honestly, I see nearly zero cosmetic use for cannabis in hair products beyond a marketing story.
-
@DAS is correct. INCI names are the “real” names.
What you are looking for are Trade Names. It’s a little more complicated.
For example, there are 41 suppliers of Dimethicone listed in the INCI Dictionary. Nearly every one of those suppliers has a different trade name for their particular blend referred to as Dimethicone.

Usually, if the system is clear, the EO has been fully dispersed. If it’s not clear, it’s not dispersed.

In the area of preservation, hope is not a good guide. In truth, I’m of the opinion that people should stick with things that have been demonstrated to work time and time again (parabens and formaldehyde donors). When you go with a food preservative like sodium benzoate it brings along with it formulation challenges and questionable safety.
But you can try whatever you like. Using a 60% active preservative doesn’t seem like a good idea to me.
-
@jeremien - it isn’t surprising. If the problem only affects a small percentage of the population, there is no reason not to allow it.
This is why list of ingredients are required. Marketers may have taken advantage of LOIs, but the real reason for having them is to alert people who have allergies to certain ingredients.

1. Your question is too vague. What is your formula?
-
What do you consider a “flash effect”?
-
You haven’t given enough information to give a good answer. For example, what is in the formula?
-
You have to try it and see. Not all EOs are the same and not all formulas are the same.
