Thank you; I will try that.
1. I will have to purchase that but I will give it a try. Is 0.3% a good amount? Would Ceteareth-20 or Ceteareth-6 Olivate be good choices for non-ionic emulsifiers?
2. Thank you; I wi…
Is it an exfoliating cream? Those generally have a lower pH. I think 3.5 to 3.9 would be okay.
Here is a list from Paula's Choice detailing the pH ranges of their various lines of products, you may find it interesting:
Linatural will likely need pH less than 5 to be most effective because of the potassium sorbate. It is comprised mainly of preservative boosters (propanediol and ethylhexylglycerol) so I doubt it would make a good preservation system.
Thank you for that information! I should have clarified that I no longer intend on using this product on my kid because of the lack of testing. It is only for my personal use now. I actually tried it as a face cleanser and it worked…
@Abdullah - Thank you for clarifying; I have never used a sulfate before, so they are all new to me.
@PhilGeis - Thank you for providing that article. Actually, I am only making this product for myself now. It was originally intended for my godson…
@ketchito - Thank you for the suggestion. I purchased SCS because it was cheaper than SLS and SLES and I thought it would function similarly.
Can you explain more about why you don't recommend it?
They lower the water activity; the higher % of humectants you have, the lower % of free water there is in the product. Humectants like propanediol have even been shown to boost the efficacy of preservatives.
My best guess is that they are using a combination of a high percentage of humectants and preservative boosters. Glycerin, propanediol, hexanediol, butylene glycol, dipropylene glycol... as well as ethylhexylglycerin, glyceryl caprylate and disodium…
@Sm00thskin - My advice would be to start small. You have too many ingredients for your first formula and it will be hard to troubleshoot any problems you may find with it.
There are three main components to a proper moisturizer:
I have been modifying this formula over the past few days, and I think I finally reached a version of it that I am satisfied with.
Increased Butter Pearls from 2 to 5% for viscosity. Decreased niacinamide from 5 to 4%. Added NatraSil at 3…
@briley57 - I'm not an expert but it sounds like one of your ingredients may be incompatible with sodium carbomer. It should easily form a gel at 0.5% without any other gelling agents.
You could possibly try forming the gel first, with only water,…
You could. The carbomer would be all you need to form a gel (try it at 0.5% and make sure the pH is in the correct range).
As for hold, I use polyvinylpyrrolidone (PVP), which as far as I know is not considered natural. There are …
Can I ask why you suggest pH 6? Is it because of the SCI?
I spoke with Valerie (she is the seller of my SCI and also a cosmetic chemist) and she advised there is no problem with using SCI at pH 4-5. 🙂
I will try …
Unfortunately, the picture didn't show up properly, but the active percentages are: * Shea Surfactant: 35% active
* Sodium Coco-Sulfate: 95% active
* Sodium Cocoyl Isethionate: 85% active
Total Active Matter is about 10% in my form…
That was one of the questions I wanted to ask but forgot to. I honestly wasn't sure how much sodium phytate is needed to be an effective chelating agent. My seller says 0.5% max so I just went with that. 😅
Yes, that is where I purc…
Looking back at this discussion, I am quite embarrassed by how ridiculous this formula was. I have learned a lot since joining this forum and have now made a new shampoo formula:
Active Matter: 10%
pH: adjusted to 4.5
* Water: up to 100%
I think glyceryl oleate can stabilize it, according to a seller it can stabilize hair conditioner and INCIDecoder says so, too.
I don't know the answers to your other questions. Hope someone will help. I am curious, too.
