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.

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.

Happy New Year!😃

Not yet a “great folk”-profesionally speaking, but getting there.

Taking this opportunity to thank you, and all the members who kindly took their time to answer/help- please know that your input is highly appreciated.

Wishing you all a healthy and fulfiled 2025🥂

1. Solubility of sodium benzoate in water is 1:1.8, so surely you don’t need much water in there, but it might be of no use in your product, because

2. It is relatively inactive above approximately pH 5. Sodium benzoate has both bacteriostatic
and antifungal properties attributed to undissociated benzoic
acid; hence preservative efficacy is best seen in acidic solutions
(pH 2–5). In alkaline conditions it is almost without effect.- as far as I know, a toothpaste should not have an acidic pH.

Both (info) from the “Handbook of Pharmaceutical Excipients”.

I don’t know if this is the clinical trial you’re after, but it looks like it could be https://brieflands.com/articles/jjnpp-114152

Happy New Year!

Please remember that Dr Google can always be of help😉

1. If you have taken the time to check the ingredients’ list of similar products on the market (sold by established brands), you’d have noticed on the said lists, things like silica, or dendritic salt, or tapioca starch. Any of these will prevent your salts from clumping, but dendritic salt greatly boosts fragrance retention.

2. You do list tapioca starch, but for an anti-clumping effect, the % should be around 10, not 1.

3. What is the benefit of introducing almond oil/any carrier oil in the formula? I suggest you take it out.

4. What’s you packaging?

I did hear this question a lot lately, but WHY?

Two points before explaining my question:

1. a fragrance longevity of 30+ min should be of concern to perfumers, not to skincare formulators;

2. if you develop a skin product with your client in mind, you’d take in consideration that the said client could be using more than one fragranced product;

Now, picture this: someone wears a fragrance coming from your skin lotion, plus the fragrance coming from a deodorant, plus a perfume or/and an after-shave, plus some fragranced hair product. This would be a “cocktail” of different fragrances with different chemical components, and if every product (except perfume) was made with the 30+ minutes in mind, who’s to get the headache, and/or nausea (or worse)? The wearer and/or the people around her/him.

The fragrance of a lotion is there just to make the experience of applying it more pleasant, not to last all day.

If it lasts 30 min+, it should be called “body-perfume”: this way people would be aware that they might not need/want an additional fragranced product if they use the lotion.

As far as my knowledge goes, both of them don’t “like” hard water, and both of them are associated with high levels of deposition when hard water is used.

Maybe this can help

You said you’ve contacted the distributors: can’t you contact the manufacturer(s)?

This way you’ll know for sure if it’s a production issue, or a “chain” related issue.

[Aniela]

Does this help?

[Aniela]

I wouldn’t use it as it’s not only NAG in a capsule. There are additives also, like magnesium stearate, cellulose and/or others.

[Aniela]

Hi,

Not a specialist, so my only comment is on the moringa and cucumber extracts: I’m pretty sure they don’t make a difference in your product (except for the increase in costs, and “bug”-food) so I’d lower them to 0.05-0.1%, just for claims.

[Aniela]

Hi,

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

https://pubmed.ncbi.nlm.nih.gov/11040525/

[Aniela]

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

[Aniela]

Thank you, indeed.

Didn’t know that about sodium benzoate’s behavior.

[Aniela]

Happy New Year, Phil- and sorry @Margaret for hijacking😇

Would you be so kind to shed some light on the use of sodium benzoate in an usually alcaline (toothpaste) product? (except the whitening toothpastes, which I assume are acidic)

Thank you.

I did notice that as well, but I assumed that sodium benzoate was only used in the “whitening” ones- they should be acidic (I think) to be able to clean so deep.

[Aniela]

Natrasorb is fine, just go for 10%- it does nothing at 1%, hence the clumps you’ve noticed.

As for stability tests, your safety assesor should be able to advice you on that.

[Aniela]

Sorry, I wish I could help, but no experience with large batches as yet. Also, no experience with Cetrimonium chloride and Ceteareth-20.

Hopefully, the more knowledgeable people will chime in. Fingers crossed🙂

[Aniela]

Thank you😌

I was about to go with 2%, but I will settle for the “middle”.

I know most of the extracts don’t make a difference, so I have no high expectations. The paper I’ve read (independent, they say) brings up some interesting possible effects of the andrographolide, so I’m just experimenting. Maybe in three months I’ll look like a teenager😁

[Aniela]

Also I doubt about the “organic” part. It might be as organic as some known synthetic preservatives labelled as “natural”.

[Aniela]

It could be ok if you test it first (in a Lab that does that) as you don’t know the level of contamination in it.

Or you could use the money for the said test to buy from a manufacturer.
