Hi Natasha,
First of all, I do not think that a “silicone replacement” will necessarily act as a real silicone.
Also, a 16% of oil might work in a conditioner bar, but I highly doubt that will work in a cream-conditioner.
Apart from the 600+ Forum discussions on “conditioner”, you might find these two articles interesting/useful:

Hi,
Some things come to mind:
1. the fragrance gets somehow “trapped” as the addition of NaCl changes the CMC, and a much larger % of fragrance is needed to overcome that;
2. I would do an knock-out experiment in regards to the three added ingredients- one of them might exacerbate the detergent smell in your formula.
3. I’m still learning, so maybe @ketchito can chime in with some real ideas????

Hi,
What does the manufacturer say in its guidance that prompted your question? -regardless of how experienced people are, it is impossible for them to know all the details about every ingredient out there.
I do not use it but I assume adding it under 40C is a sensible choice.
Also, I assume you already know that it won’t penetrate the skin, so a good combination of humectants might/will do a better job.

Apparently not the seaweed as such, but some isolates are beneficial for quite a few skin-concernes:

Cosmeceutical Significance of Seaweed: A Focus on Carbohydrates and Peptides in Skin Applications
The term ‘cosmeceutical’ refers to cosmetic products that offer medicinal or drug-like benefits. Marine algae are rich sources of bioactive compounds, particularly carbohydrates and peptides, which have gained attention for their potential in cosmeceuticals. These compounds are abundant, safe, and … Continue reading

Hi Natasha,
You say you’ve “checked the FDA list of approved colorants for cosmetics (making sure they are safe for use around the eyes), and I found that only these colors are allowed: Blue 1, Red 40, Yellow 5, Green 5″.
As I understand, you’re making a shampoo, therefore the restrictions for “Eye Area” definitely don’t apply for shampoos, they are in place only for products applied in the eye area. So, you have access to more colours than you thought, and this should/might make your task easier. I’m not in US, but I’m pretty sure you should only look at the “External Use” column.
PS- there are quite a few specialists on this forum with a vast knowledge in shampoos, but because you said “color-cosmetics” aka make-up, none of them has chimed in; I suggest you post again your question, under a title containing the word “shampoo”, and for more help, also share the results of your experiments to date.

If it’s of any help, the EU says “All ingredients have to be labelled on the packaging. An incomplete listing of ingredients is
considered to be misleading.
However, there is a provision whereby certain materials are not considered as ingredients. The
relevant extract from Article 19.1(g) states:
“For the purpose of this Article, an ingredient means any substance or mixture intentionally used
in the cosmetic product during the process of manufacturing.
The following shall not, however, be regarded as ingredients:
(i) Impurities in the raw materials used;
(ii) Subsidiary technical materials used in the mixture but not present in the final product.”
These definitions are reasonably clear. Subsidiary materials not present in the final product
would include filtration aids and decolourising agents, both of which could be added during
manufacturing but would subsequently be removed.“ -
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/

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.

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.

To clarify, “it won’t make a big difference” was meant for the skin-feel, not the stability.
-
Considering you’ll reduce the fatty alcohols and add more shea, it shouldn’t make a big difference.
What’s the INCI name of your emulsifier?

Second time is a charm????
-
Yey! I’m pretty smart????
Joke aside, thank you for confirming my thoughts. I was also tempted to point the polyquaternium 7, based on past experiences with polyquats. I didn’t, because I feel almost like a fraud for not being a chemist/pharmacist/etc, and being less able to express my thoughts in chemical/professional terms.
But I’m working to get there????
Thank you, again.

Hopefully after a walk (fresh air) your nose will “perform” better????
It’s always good to learn new things, so is it too much if I ask you to share the “culprit” after you finish your experiments?
Thank you.

Sorry, a bit confused: by “allergen analysis” you mean the calculation based on the COA provided by your supplier, or proper Lab testing to check if the said COA is accurate?
-
The thing is that MOST of the functional ingredients (actives, preservatives, sunscreens, etc) we are using today (and most of the essential oils for that matter) have been deemed safe AFTER were tested in labs (on mice, rats, rabbits…)=> they’re NOT “cruelty-free”.
As for the natural things, let’s take for example Amazonian/African butters/oils: are you 100% sure that none of the fauna or flora members were affected by the harvesting process (nuts or fruits or whatever)? As in they could find the same amount of food and shelter as before the “natural” trend/madness started?
My point is “cruelty-free” is a lie in most circumstances, whereas “product not tested on animals” is more accurate, if indeed only clinical trials on humans were performed.
-
The time you keep the sample should be equal to the shelf-life of your product.
No hard rules on labelling, manually is fine.

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

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.

Hi Natasha,
No worries, English is not my first language either.
Wishing you best of luck????
