Hi,

Regarding “vegan”, you should find details on the technical documents of your ingredients: usually they will say “vegan certified”.

Regarding the big BS of “cruelty-free”, you should read this (other sources available if one really wants to know) https://chemistscorner.com/cruelty-free-cosmetics-are-they-really-free-from-cruelty/

Cruelty Free Cosmetics - Are they really free from cruelty? - Chemists Corner

Hello and welcome to Hot Topics from Chemists Corner, the show where I pick some topic about the cosmetic industry that caught my eye and…

Hi Alejandro,

As I’m not familiar with some of the ingredients you’ve used, I can only suggest to use the search function on this page- I know for sure that the subject of “hair pomade” has been discussed here more than once.

[Aniela]

This being a leave-in product, I’m pretty sure that less is more- meaning to pay attention at the quantity you’re applying on your roots.

You have here full guidance, plus a video

Maybe give this one a good read, and see what you can add/modify

A few things:

1. There is quite a good number of papers out there, showing that 4% niacinamide is the “sweet spot” for dealing with acne/acne prone skin.

2. When making cosmetics, less is usually more: using 10% of niacinamide as suggested here will only pave the road to sensitize the skin, plus there is no data showing that at that level will bring more benefits.

3. It could prove useful to pair niacinamide with some other beneficial ingredients.

Hi, @ozgirl is right about the bicarbonate; you could explore less irritating ingredients.

Also, if you conduct a search in the Forum on “deodorant”, you’ll find a lot of info.

Hi Jonathan,

This is what I know, and what I would consider:

1. The temperature range where your product starts melting- if your product is meant to be used in the Russian winter, it needs another melting point and texture than when it is going to be used in the African summer;

2. The texture of the product:

a. To check for graininess (even if it’s not apparent), keep the product at room temp. for 2-3 weeks, and then assess its texture; it should be smooth and homogenous, and if any graininess, reassess your method;

b. What happens to the texture in case the balm undergoes temperature changes (much higher or much lower than room temp) during transport and application? The product should always come to the initial texture when back to room temperature.

3. The container’s integrity: what happens to the balm in case it melts in the container? Does the container leak or does it remain sealed? How does the container react to changes in humidity?

To answer to 2b and 3, a simple method is to run three cycles as follows: 24h at 45C, 24h at room temp, and 24h in the fridge.

Check the texture and appearance of the product after each cycle, as some issues can reveal themselves earlier in the process. Also check if the product leaks from the container if upside-down/on the side when it’s melted.

I hope this helps.

Apart from your title “4 ingredient conditioner bad” not reflecting the reality, there are a few more things to be said:

This is a group where professionals offer their time and advice for FREE- personally, I’m very grateful for having access to their expertise.

You didn’t experiment with your four ingredients, you just treated this Forum like a “mommy’s blog”, and launched a “click-bait”- not fair for anyone here, as we don’t do that.

You can ask specific questions, but for now you’re basically asking for a free formula- again, that’s ok in other groups, not here.

I hope this helps, as this is a very good place to gain knowledge and become a better formulator.

Have fun experimenting🙂

[Aniela]

Hi,

A few things come to mind:

1. Color cosmetics is a term used for decorative cosmetics;

2. Experimenting with the shampoo base and the colours on hand, will give you the answers you’re looking for; nobody can guess how they will behave in your formula, and less so, what %s will give you the desired colours; manufacturer’s guidance could be a good starting point;

Side note: as a customer, I would expect that the colour is added to visually differentiate the shampoos based on hair-concerns, but if too many options are presented (three seems resonable), I would go for something that I already know and trust.

Best of luck in your experiments.

Hi,

As Nivea is owned by Beiersdorf, I suppose the patent you’re looking for should be here https://patents.justia.com/assignee/beiersdorf-ag

There are many patents they own, therefore many pages, so you’re in for an “adventure”…

[Aniela]

You can use glyceryl stearate as a co-emulsifier if you want, but you need a proper emulsifier in your formula. That should solve the “water-issue” you described.

Glyceryl stearate by itself is a weak emulsifier, it won’t help you obtain a stable emulsion.

[Aniela]

Hi,

There is a 2024 Iranian study I’ve read (Kopexil vs Minoxidil), and they dispersed the Kopexil in a solution of ethanol and water, in a ratio 70:30 (the dispersion process was carried out under continuous
stirring using an overhead stirrer, until a homogenous
mixture was obtained).

[Aniela]

Hi, not an error.

You could check it on UL Prospector. The commercial name is Tyrostat™ 11.

As far as I know, this product is not available to retailers, thus little to no info on it.

[Aniela]

Hi,

The title and explanation are a bit misleading: olivem 800 is not PEG-free as “ceteareth-” refers to a PEG (polyethylene glycol-) ether of cetearyl alcohol; the number behind “ceteareth-” refers to the average number of molecular units -CH2-CH2-O- (explanation under “ceteareth-6” on cosmileeurope.eu)

That being said, you could check this blog https://formulabotanica.com/organic-sprayable-body-lotion-sucrose-stearate/

[Aniela]

I would apply @evchem2 suggestions.

Regarding the solubilizer, the manufacturer lists, under “Incompatibilities”: vegetable oils and cationic surfactants.

[Aniela]

Have you checked Fraterworks?

The shipping fees might be lower than one would expect.

[Aniela]

The time you keep the sample should be equal to the shelf-life of your product.

No hard rules on labelling, manually is fine.

[Aniela]

I planned to stay out of this conversation, but assuming you’re here to add to your knowledge, not to follow any formula you’re given, I have some things to say:

I’m sure the professionals here could have given you more than one formula, but this forum is not about that. As one of them said a while ago “It is best used as a source for research and direction for your further study.”

Considering you inquire about a probiotic, it seems you didn’t take the essential from graillotion’s comment: picking a theme and sticking with it. That meant to decide if you’re going to make an anhydrous product- usually an alkaline ph, or go for a water-based one- usually an acidic pH.

Pretty often people think that an anhydrous product is much easier to make than an emulsion: far from the truth, as one needs a good number of experiments to come to a great result. I suggested you to read the posts on “deodorant stick” because one could learn A LOT from all the comments, and also do a lot of research, prompted by the same comments. Also, more often than not, you’ll find a link or two, which will spare you a lot of searching-time. So a win-win for you.

I assume you’re going for “natural”, so taking a good look at the ingredients used in the “natural” solid deodorants out there will help you understand the concept they are based on. That does not mean that they work for everyone, but it’s a good starting point. You’ll also notice that they don’t use most of the ingredients you use in your formula, and there’s a good reason behind that.

Best of luck with researching and reformulating🙂

PS- no, deodorants are not sticky by default- if they are, it’s a formulation issue

[Aniela]

Regardless the cost, the “observation-sample” should be the same size as the one you’re selling, and in the same type of packaging.

[Aniela]

Thank you for answering.

I’ll definitely dig deeper.

I was just curious if there are more incompatibilities than in my supplier’s guidance “sensitive to electrolytes; not suitable for thickening shampoos or shower gels containing higher amounts of salt“.

Based on your answer, there are: you advised me to use it after emulsification, because it is sensitive to high shear forces, whereas my supplier says “usually added to the oil phase, gentle agitation facilitating dispersion“.

I’m in Eastern Europe, and the few suppliers in my country are keen on selling “natural” ingredients. I’ve found some synthetic ingredients which looked interesting to me at two labs, but they sell to the pharmaceutical industry, so there’s a minimum order of 20 kilograms🙃

[Aniela]

Hi,

I do not have any experience with synthetic polymers, only with the so-called natural ones.

My supplier started recently to sell Aristoflex AVC, and I’m thinking to order it and experiment with it.

Would Aristoflex AVC work in a formula similar to what you’ve described here, please?

Any idea where it fits best? My supplier is pretty scarce with the using guidance.

Thank you.

[Aniela]

Hi Natasha,

No worries, English is not my first language either.

Wishing you best of luck😃

[Aniela]

Hi,

According to this, there are some acidic ones, or there were- the article is from Sep. 2000

[Aniela]

Thank you for the article, and no worries- somehow, my brain read “increased”.
