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.

Does this help?

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.

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.

IFRA Conformity Certificate should be issued by your supplier when buying essential oils & fragrances: it contains the %s allowed for each category of products, from baby care to household products.

Regarding the use of limonene, as you’ve noticed, they’ve used it for cleansing purposes (I use 10-15% in a dishwashing paste).

The comment “… I’ve seen an allergen intentionally added as a pure substance in a cosmetic formula, as an ingredient itself” is a bit too much: they used a chemical they considered fit for the product, they didn’t purposefully looked for an allergen and decided to try their luck.

To clear your confussion, here’s an extract from the IFRA Certificate of sweet orange essential oil, which contains 70-90% limonene.

Hi,

Although old, this article will answer some of your questions https://pmc.ncbi.nlm.nih.gov/articles/PMC7245492/

[Aniela]

…and this is where math and the author’s thinking (the author of your quote) might collide:

A ratio of 100:15 is greater than a ratio of 100:20, again, mathematically speaking. Increasing monoethanolide, you’ll get smaller and smaller ratios, whereas increasing the detergent solution, you’ll get greater ratios.

@Adamnfineman might be right, if the author used a poor choice of words to explain himself.

Oops, the right phrase is “The recommended dosage of LABSA 96% in household detergents is 5.0%-25.0%.”.

[Aniela]

Hi,

Just googled LABSA as I’m not familiar with it, and found two things you seem to disregard in your formula: 1. “Incompatible with bases, metals, and oxidizing agents.”, and 2. “The recommended dosage of LABSA 96% in household detergents is <strong style=”font-family: inherit; font-size: inherit; color: var(-bb-body-text-color);”>5.0%-25.0%.”.

The 40% natural oils won’t help the product to feel “ultra light”. Cutting those down to max 20% (providing they are light, not rich) and adding 65-70% of cyclomethicone or isododecane or LuxGlide N5, plus around 10% of C12-15 or hemisqualane will give you a good hair product.

Hello,

My supplier sells water soluble fragrances which come under the INCI parfum/aroma. They come with IFRA certificates and Declarations of Allergens, so one can decide if using or not.

They are alcohol based, and I’ve used three of them (melon, mango, strawberry) in face cleansers, shower gels and shampoos for the family. The scent doesn’t/didn’t fade over time- I’ve kept samples and checked that. The children used the products as well, and no skin-issues apperead.

I assume there are fewer of these on the market for two reasons: the oil-based ones are more versatile (most of them can be used also in candles, soap, etc), and the fear many formulators have regarding the use of alcohol in cosmetic products, no matter the %.

Hi,

1. This post will help https://chemistscorner.com/cosmeticsciencetalk/discussion/cationic-emulsion-system-questions-for-lotion/

2. No idea.

3. No idea either, as I don’t use them in skin moisturizers.

[Aniela]

You can try here https://www.myskinrecipes.com/shop/en/natural-gum-thickener/1282-dehydroxanthan-gum.html and they might have the other products you’re looking for. They do ship internationally.

[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.

[Aniela]

Math is clear, but what is the reason behind considering 1.5% as a baseline if the TDS says 1.5-3.5%?

Thank you.

[Aniela]

Thank you, Kristiana.

So if the extract itself is present in the product at 1.5-3.5%, andrographolide makes 10% of that, right?

[Aniela]

Thank you for trying to help.

[Aniela]

Any idea what’s the answer to my question, please?

All good, no issues😇

[Aniela]

Thank you for pointing that out: I admit I didn’t think about storage.

[Aniela]

Considering that they use Castile Soap, I assume you might turn the mix into a thick paste. Although, I wouldn’t use soap as a binder or foamer- but to each it’s own.

[Aniela]

Thank you.

Hello @chemicalmatt ,

and thank you @Abdullah for making my question possible.

I’m not a chemist, therefore your help is much appreciated: after reading the article, my take is I’ll be better off (stability-wise) if using cetearyl alcohol instead of only cetyl alcohol.

Is that right, or it largely depends on the emulsifier used?

Thank you.
