ethyl alcohol or lexgard mhg (methylheptylglycerin)

[natiyo123]

phenethyl alcohol, an organic acid and propanediol?? also the PEA will go well with your scents

[natiyo123]

sodium lauroyl lactylate is a SOLID so it WILL thicken your final product

[natiyo123]

im really curious, doesnt triacetin convert into acetic acid once its on the armpit and thus smell like vinegar???

[natiyo123]

are u sure its refined? I use 5% in my formulas and the smell is barely there, maybe try adding musks, they make volatiles “Heavy” so they wouldnt smell so much…

[natiyo123]

mm starch will not gelatinize without water, sometimes in my case it burns a little but it doesnt affect the “Mushiness” of my stick

i dont think it matters the temp at which u add the magnesium as long as the rest is melted

I would try adding solid emulsifiers or beeswax

@Monty Other than pinning this problem back on the client who “formulated” it, not much you can do without DEL/ADD other ingredients. The starch and MgOH2 are in suspension as Graillotion mentioned, as this is anhydrous (correct?), so your problem is with stearyl alcohol. Subbing ceresine or microcrystalline wax for C18OH will help immensely, and adding a little polyglyceryl ester will keep it from mushing too, but they insist on you using their formula right? My question is: what the heck is suspending those solid-state “active” powders? Not that either is actually deodorizing anything, mind you, but during a hot-fill operation you need some yield value to maintain suspension while filling and cooling. See: quaternium-18 hectorite in most suspensoid antipersiprants having the dreaded aluminum-zirconium active ingredients.

im interested in this too, why is stearyl alcohol a problem?

[natiyo123]

I have read the data sheets, of most of them. They seem very similar to each other, except price. Thats why Im asking.

the main deodorant ingredients are ZInc Ricinolat and Antimicrobial Raw Materials like Sodium Caproyl/Lauroyl Lactylate

I would always go with zinc Ricinolate because it has a Scent absorption/binding activity and does not harm the Microbiome of the skin. 

Of course, you can just use some Other not so Allergic Perfum to cover the negative scent depending on the time you want the deodorant to be tested.

There is the possibility of using Triethylcitrat which is deactivating the deconstruction of sweat and therefore eliminates ba d scent as well.  

Combination of different areas, for example, Decalact Deo  (Sodium Caproyl/Lauroyl Lactylate, Triethyl Citrate, Salvia Officinalis (Sage) Oil) are very helpful if you don’t want to eliminate only one threat.

thanks, all of these are good ideas…  I should have mentioned from the start my formula… my actives are TEC, glyceryl Caprylate, Glyceryl Undecylenate and ethyl hexyl glycerin
but I still wanted to add another layer of protection with antimicrobial aroma chemicals… I want to make a very potent formula because I live in a tropical country. I have never tried zinc ricin. I should give it a try!

Graillotion said:

As with any allergen, some will have a response, and many will not.  You can create the same result with ingredients that have a lower chance of an allergic response.

You just decide how many responses are acceptable and formulate with that in mind.

can you suggest some of these ingredients?

@natiyo123 - except it’s not hypoallergenic to the people who have an allergic reaction to it.

No chemical is free from causing an allergic reaction in some peopleMicroformulation said:

There are several papers one can find describe a contact allergy to Castor oil. With the most minimal effort here is just one; https://www.mdpi.com/2079-9284/4/1/5/htm

I read both papers… is the first one a good reference? I mean the woman chewed on castor beans xD… the second one got me thinking

[natiyo123]

well im confused now, because its labeled in the EPA safer choice list as a green circle, to be considered this, they cant be sensitizers

[natiyo123]

sodium stearate or PVA

[natiyo123]

castor oil is hypoallergenic

[natiyo123]

soo youre handling aluminum salts and formulating antiperspirants in your kitchen??? I find it a little concerning tbh. Be careful!

[natiyo123]

thank you!

I have played around quite a bit with this ingredient and I do like it. I have not subjected it to PET yet as I have had no customers pick up a formulation with it in so far. But generally it doesn’t cause any instability issues in emulsions and I would always use something else with it, perhaps a natural glycol or Lexgard Natural. Although I have not challenged it, I have never had any visible (mould) growth on the surface of my samples. For me, if it is Cosmos certified then I will accept it as natural. One other point I like about it that it can be used up to pH 8 which makes it suitable for mineral based natural sunscreens and natural mascaras.

Thanks!

I have worked with this compound. Certainly, it cannot be considered as “natural”. Its properties are very similar to ethylhexylglycerin as well as obviously, they are completely comparable from the chemical standpoint. Comparable but… but they cannot replace each other. EHG outperforms MHG. However, MHG has nicer emollient properties and leaves velvety smooth not tacky finish on skin. MHG works as EHG in deo formulations, but its deodorizing efficacy is lower. We also compared two combinations EHG+Phenoxyethanol and MHG+Phenoxyethanol. While EHG+phenoxy works as a preservative in some formulations, MHG and phenoxy showed insufficient activity and required additional components. However, the combination of EHG+MHG+Phenethyl alc. was highly efficient against all potential microbial agents, including Aspergilus n., Pseudomonas, S.aureus and yeasts. We also found that MHG was efficient as antidandruff preparations as the only active ingredient at 2.2%.   

oh wow, very interesting. Thanks for the information.

thanks. Yes I read this before, but there wasnt more information besides this on the internet, thats why I was wondering if anyone had any experience or comments using it.

[natiyo123]

hello anyone? please hahah

[natiyo123]

was thinking the same, maybe the beeswax? can be quite sticky

[natiyo123]

I know it´s not ideal to make deos in a kitchen but it´s what I can do for now …

[natiyo123]

well at least now I know what to look for in the future hehe… thanks

[natiyo123]

I should have been more specific, in this case by “natural” I mean, that it can be extracted or used directly without too much processing or treatment…

interesting formula, is there a reason why the extract (50% saponins) was only used at 1.5 % ???
