HEC is mostly used in personal lubes because it has very slippery feel. Not sure you want it in a face cream. I would suggest switching to Xanthan Gum Soft or even better some synthetic polymer like Sepimax Zen or Aristoflex.
But if we look even deeper to the original intention. You want to make your face cream creamier. Usually we use oil thickeners for this. Cetyl Alcohol is the one who gives this creaminess feel without making the cream heavy,

MemberSeptember 30, 2024 at 3:42 am in reply to: What solvent/s can be used to solubilise these 3 UV filters together?Hey! I know you from reddit DIYBeauty sub. Remember their rules? No DIY sunscreen? That’s because you will never be able to make sunscreen at home.
Sunscreen works by creating an even layer on your skin. It is not about the filters, solubilizers or high content of the filters, it is about even distribution of nano particles. Some filters are in nano form and not really solubilized, but distributed/dispersed so well and even that you think they are dissolved. For this you need really high end equipment and knowledge.
So drop this idea and buy one.

Sunscreen works by creating an even layer on your skin. It is not about the amount of oxides, it is about even distribution of nano particles. For this you need really high end equipment and knowledge. Even if you smear pure zinc oxide on your skin it will give you spf 5 top.
So drop this idea and buy one.

Also, mineral sunscreens are not totally mineral per se and contain unregulated SPF components: https://www.youtube.com/watch?v=_Lcakmug-c0

MemberSeptember 19, 2024 at 3:39 am in reply to: What is the best actif or combination for whitening cream?I wonder why no one mentioned Tranexamic Acid. It was mentioned in one of the recent Beauty Brains talks from Perry and Valery

If you check the washes on the market you’ll see that they don’t use Citric Acid, but Lactic Acid instead. And the pH is lower than skin pH, around 4.5 (or I’ve seen even lower)

Formalin? 😨 Is it even allowed in skincare?

Obviously the wrong thing with the formula is that it doesn’t have any percentages and manufacturing process
-
I am making a dish and I want to add 2tbs of sugar. Will it cause troubles? Will it be too sweet or not enough? There is no answer unless I mention the whole recipe and processing for it.
Same goes to yours question. How could we tell anything if you don’t provide the whole formula and manufacturing process?

Oils separation. Neither Xanthan Gum nor Glycerin are emulsifiers. What you do is just making a thick gel and then disperse oils as small droplets inside. Since there is no emulsifier with time these droplets stick together, separate and make a coating around lumps of swollen Xanthan Gum.

MemberSeptember 3, 2024 at 3:56 am in reply to: Niacinamide toner develops white residue on containers and surfacesSure it is Niacinamide crystalizes. When toner dries out the water is gone and all solid ingredients become powder, obviously.
One way would be to add a mix of humectants, like Glycerin + some glycols. They will prevent water evaporation so quickly, but still won’t prevent it if you leave it open.

MemberAugust 19, 2024 at 3:27 am in reply to: What are some good moisturizing ingredients you can put into an aqueous toner?For myself, I use:
- A mix of Glycerin, Panthenol, Pentylene Glycol, and Propanediol
- Sodium Lactate
- Aquaxyl
- Urea
- HA to thicken it a bit

MemberAugust 16, 2024 at 8:48 am in reply to: Why is there a ban on vitamin D in EU? Anyone knows the reason they gave?A quick google search shows that not vitamin D in general is banned, but vitamin D from specific sources (with reasons) and a brand of vitamin D products. So no, Vitamin D is not banned in EU

It is actually very high, usually it is close to the preservative.
You can’t get the precise amount of ingredient just by looking at INCI, because INCI is a relative order. Next 2 INCIs are the same, but concentration is different:
INCI 1: Water (96.3%), Glycerin (2%), Propanediol (1%), Xanthan Gum (0.1%), Phenoxyethanol (0.5%)
INCI 1: Water (92.2%), Glycerin (5%), Propanediol (3%), Xanthan Gum (0.3%), Phenoxyethanol (0.5%)
The first is a watery toner, The second is a serum. And although they have different concentration, their INCIs are the same. Without knowing the actual percentage you can’t guess how much of ingredient is inside just by looking at relative order.
Kerastase is a world-wide brand. If manufacturer says it is 3% - then it is 3%, otherwise they can get sued and none of big brands want this.

Water-soluble ingredients are water-soluble. They are not oil-soluble. Water-soluble ingredients won’t dissolve in oils, because they are water-soluble and not oil-soluble.

MemberJuly 15, 2024 at 8:10 am in reply to: Alternatives to glycerin for dissolving Xanthan Gum or CMC?You can’t dissolve Xanthan Gum in Glycerin. You can create a suspension (evenly distributed powder in medium).
As a strong humectant Glycerin attracts water from the air. This water wets Xanthan Gum and jellifies it. So I don’t think you can store it as is.
The technique is used only to premix the gum right before adding it to the water, not to store it.

I suspect “Xanthan Gum Transparent” is another name for Soft grade in your suppliers list.
I assume the reason it bubbles is the very high amount of HEC. The product is just too thick and bubbles can’t get out

Xanthan Gum has different grades. You need Xanthan Gum Soft. And definitely not the food grade.
Why do you even want to hydrate HEC? Just put it to oil phase, it gonna hydrate itself during emulsification.

As I said it doesn’t matter what your base is because you don’t have right equipment to disperse the filters. It is just out of reach for DIY. So I promise your result will be 100% failure no matter what DIY technique you have in mind. And since the reliable testing for SPF costs a lot and burns real persons I would strongly encourage you from doing DIY sunscreen because it will fail, you will loose money and hurt people for nothing.

MemberSeptember 30, 2024 at 3:45 am in reply to: is oil(not cream based) sunscreen(viscosity like moroccan hair serum) feasible ?As I answered you in another post - drop the idea of DIY SPF product. Unless you have high end equipment to make and test the product you will never be able to reach any reasonable SPF. The danger here you will think it works while it doesn’t.

I think they just added a lot of fragrance. And Citric Acid is at 3% as they claim.

why make all these slurries and pre-gels? It baffles me why so many formulators do this
Because it prevents clumps if you do it at home with no special equipment? In my humble experience it works at least for Xanthan gum
