Since you purchased it from Makingcosmetics.com there is no way to know exactly which Tradename Guar you are using … they could be re-packing any grade of Guar from any manufacturer, but they do indicate that you need to reduce the pH to process it is @Vjay noted above.
-
No one said that Euxyl 9010 was an appropriate preservative for every product. Proper Preservation is much more than just adding one ingredient to a product … it involves hurdle technology apporaches using a variety of ingredients such as glycols to reduce water activity, chelants, preservative potentiators and the preservative itself.
-
What specific Tradename Cationic Guar are you using? … Some require a specific pH adjustment to hydrate properly.
-
Could be for a variety of reasons, the primary one being that some clients may not want Benzyl Alcohol in their formulations since it is a known irritant. Others may not have a problem with that. They are in the business of developing preservatives, so logical that they would come up with as many blend combinations as possible to broaden their product portfolio.

ngarayeva001 said:@vjay, phenoxyethanol doesn’t protect from the mold. You can’t use it as the only preservative, you should pair with other preservatives.
@vay posted: “You can use Phenoxyethanol and Ethylhexylglycerin” … that is a combination of preservatives that should work perfectly fine in this product class
-
Yes, the aforementioned Hyaluronic Acid, Sodium Lactate or Sodium PCA if you want performance somewhat superior to Glycerin. You should also take a look at Saccharide Isomerate or Betaine (an osmolyte). Hyaluronic Acid will be the best, but also the most expensive, by quite a bit relative to the others.
-
There’s the “No Glycols” segment of the natural community that @Spadirect might be catering to … this includes Glycerin as one of their targets.
Sorbitol, Sodium PCA, Betaine … lots of options here as substitutes for glycerin.

There really is no need for you to switch from Leucidal Complete if it is working for you … if it is passing these PCT, it’s passing. If you do want to supplement it, you might consider adding Naticide (Parfum) from Singera.
-
Leucidal / Leucidal Complete are highly formula dependent in their effectiveness, particularly against A. Brasilliensis. I’ve had Leucidal Complete fail on more products than it has passed and I only use it if the client absolutely insists … otherwise, I always advise against it as a main preservative.
-
It would appear that they are using a pre-neutralized carbomer (note there is no TEA or NaOH base listed to neutralize the carbomer) and I suspect the Alkyl Benzoate is at a low percentage (1% or so) and they are just physically jamming the Alkyl Benzoate into the carbomer/sclerotium gum matrix.
Not the most elegant approach.
-
The problem is that your Sodium Coco-Sulfate is too high @ 25%. Cut that down to 12% or so.
-
No, I mean you’ll need at least 20% - 30% 1,3-propanediol to keep the SA solubilized. Sodium Citrate you would use at 1%.
-
(1) Heat the 1,3-Propanediol to 70C, add the SA to the hot solvent stirring until is dissolves
(2) Add Sodium Citrate to water, heat to 70C
Slowly pour the hot SA solution into the hot water. Add the surfactants and any other ingredients you desire.

There isn’t anything obvious that would function as a deodorant active per se, except perhaps the Clary Sage.
If the LOI is correct, most of the work would be done by the high level of Mandelic Acid creating a low pH surface on the skin where this is applied plus some antibacterial effect from the EHG/Phenoxyethanol & Clary Sage.
-
I would suggest that you first actually define your product(s) concepts and project …
All you have given are broad generalities … some undefined novel skincare solution using active technologies like “medicine” and bioavailable ingredients.
-
Yes, you can use a combination of 1,3-Propanediol @ about 20% to 30% + 1% Sodium Citrate … if you’re using SA in the 1% range, that should do the trick. Keep your final pH around 3.8 to 4.0.
-
I’ve never seen anything substantiating that chleators are rendered ineffective in clay products, but if you have some credible evidence of that, by all means post it up.
-
Dimethyl Isosorbide functions primarily as a solvent and penetration enhancer. You can use it in the 1% to 5% range. Yes, you can use it around the eyes. Smells horrid, so be aware of that in advance.
-
Clay products are notoriously difficult to preserve. I would recommend that you consider adding Tetrasodium Glutamate Diacetate (chelating agent), Phenethyl Alcohol and either p-Anisic Acid or Naticide (Parfum) to bolster your preservative system and bring your pH down to 5.0.
-
The answer is “Yes” you can make a pre-mix blend to save time. If you are going to go commercial at some point in time, best if you weigh each component as opposed to using drops as a measure as noted above.
-
Note that it is pink in color … Rose Oil is not Red … there is no solubilizer mentioned on the LOI, but there is no separation.
Recommened In The Edgar Cayce Reading tells you all you need to know … Adulterated Quack Water

You are now asking questions beyond the scope of free advice.

Don’t confuse being ECOCert-compliant with being Natural. ECOCert does allow some synthetics. Benzyl Alcohol & DHA is an ECOCert-complaint Preservative, but that does not mean that it is natural.
If you want to claim 95% Natural, that is fine, but you should be precise in your definition.
If you want your product to be 100% Natural and claim Natural, then there are options regarding your emulsifier and preservative that will allow for that.
-
I think you are treading on deceptive grounds … your emulsifier components are derived from natural sources, but the individual component ingredients are in fact synthetic. No, unless your Benzyl Alcohol is specifically natural source BA, which is highly doubtful, it is synthetic as is the DHA. So, you really cannot say that your product is Natural.
-
Your emulsifier would be considered “Naturally Derived”, but not “Natural”
