Easiest way is to reduce tacky inputs. If you are dealing with G… then see if you can sub some of it for 1,3 propanediol, or butylene glycol.

Otherwise, your other option is to ‘out slippery’ the sticky. Use emollients/esters at such propensity, the slippery aspect prevails.

I found it on Amazon. There is no barrier to entry on Amazon.

Based on the reviews, I’d probably not use this as a benchmark. 😆

Looks like it comes out of….. India (no comment).

Yes, I would throw out anything with a Geogard preservative! How did you expect to cover Gram negative bacteria?

The poor job that Geogard preservatives do on the other aspects of the formula, are very pH dependent, and you did not even mention pH??? Above a pH of 5.5, the product isn’t doing much on the Gram +, and YMF.

Just because other beginners use poor preservation, does not mean you should follow the herd. Consider the health of your customers, and family.

You should understand that very clever language is used to manipulate those without the science backgrounds…. everything down to the worst of the worst….will use meaningless terms like ‘broad spectrum’. I cannot think of two more meaningless words in cosmetics!

I have seen the method that beginners use to select their preservation systems…. They will …. wait for it …. survey other beginners on what to use. Do you see any concerns with that?

[Graillotion]

A little confused with the question…..unless you are being name-brand specific.

Posting your country….is always of value, on Q’s like this.

I don’t buy ingredients from Amazon….but thought this was funny.

Is that something different than was is typically called ‘Bay rum’ fragrance? Everyone sells it.

Bay Rum Fragrance Oil – Wellington Fragrance

Bay Rum Fragrance Oil

The traditional mans fragrance, similar to Old Spice. Invigorating and masculine, with spice notes. Top: Apple, Orange, Cinnamon Leaf, AllspiceMiddle: Dark Rum, Bay, Clove BudBottom: Benzoin Resin, Patchouli, Tonka, Vanilla, Musk

[Graillotion]

I am having a little trouble following the timeline. But it sounds a little like a phase inversion (for lack of details). This occurs when an emulsion tries to first become a W/O instead of O/W. They manifest as being very thick at first. Typically once you reach a certain point that breaks…and tries to return to O/W which is typically far less viscous.

Again… without a detailed description of what is happening at what point in time… I could be way off.

[Graillotion]

What I hear you saying is… the knives in this drawer …. are a little sharper than Tom Sawyers friends? 😆

[Graillotion]

With all respect you said:

“The mosquito-repelling is done by an essential oil called Eucalyptus Lemon Scented Gum Oil (Eucalyptus citriodora)”

What your intent with that language was….only you know. How a beginner will read that…we all know…..

• This reply was modified 2 months ago by  Graillotion.

[Graillotion]

Then you already know that Lemon Eucalyptus oil has almost no repelling, other than beyond placebo levels. The essential oil is often mistaken by novices as the same thing as Oil of lemon Eucalyptus, which is it NOT. OLE contains high levels of PMD, which have been proven effective. Lemon Eucalyptus E.O has very negligible amounts of PMD.

You just feed the mommy blogger lore, when you don’t make these distinctions in your post.

[Graillotion]

Back to your original question….let’s call in the expert, Dr Geis…. @PhilGeis Do you see any concerns with heating a preservative containing: Benzyl Alcohol (and) Salicylic Acid (and) Glycerin (and) Sorbic Acid

To a temp of 75C?

PS: Time to buy a pH meter. 😉

Ahh…………..

Yes the iscaguard PEG will help. We don’t work in brand names….just INCI.

So I finally looked it up….and it contains phenoxy….which will get the gram -.

Good luck. (Going forward…..tell us what is in things…. we don’t memorize brand names). 😉

[Graillotion]

The entire line is weak on Gram - , hence why it is mostly relegated to beginners. Granted you can use them as a starting point… and build off of them….but why bother, when it is simply easier to preserve correctly right out of the gate? The link I sent…addressed the additional version you inquired about.

It actually brings a new set of problems….and that is pH drift with the Gluconolactone.

By the way Vit E has no effect on preservation. It is an antioxidant, not a preservative. And worse yet, at the rate you used it….it is a pro-oxidant vs the desired outcome. In cosmetics….it is quite often the case….that more is worse. The E rate that will be sufficient will be .05% - to .2% if you think your product is old and low efficacy (the darker it is…the more oxidized it is).

Yes, I was aware of how little of those strong anionics they use in those blends. In the past I have used SSG as a co-emulsifier quite often.

As of late….I have fallen in love with SPDMA as my co-emulsifier. 😆 Just had to learn to love HP starch….and I have a new love.

I don’t use Rita M…. was just trying to help out some beginners. In your answer you mention oil content…. since the topic is beginners….we know there is too much oil. But could you extrapolate on that idea?

Aloha, and thank you for your time and input, @ketchito .

[Graillotion]

This (excellent) company sells very small samples….so it is not costly to give a handful of interesting fragrances….a trial.

For women…. they have an English Pear and Freesia…..that most women swoon for.

If you use those dreaded EO’s …. one of the few non-citrus….that I can even tolerate….is their Himalayan Cedar… pretty neat stuff… not the same nasty cat pee and pencil shavings you get from most cedars….quite sweet.

[Graillotion]

Yes….Bay rum is the iconic knock-off of Old Spice. Granted in this space….there are 100’s of sellers….there are also likely several mfg’s ….. So the knock-off could vary from seller to seller.

It never appealed enough (at all) to me…..to evaluate. If you want two modern scents….that will make folks swoon…..I will attach them.

Aventus Creed Men Type Fragrance Oil – Wellington Fragrance

Woodsage & Seasalt Jo Malone Type Fragrance Oil – Wellington Fragrance

Give those two a ‘look-see’.

[Graillotion]

@ketchito What about those emulsifiers that contain both? ie Ritamulse? (Glyceryl Stearate & Cetearyl Alcohol & Sodium Stearoyl Lactylate) I see those folks having issues with phase inversions….is this due to the emulsifier blend, or more probable that their addition of additional fatty alcohols is throwing the soup out of balance?

[Graillotion]

Many people do not realize….the chelate has the second most profound effect on preservation. They just view it as something that keeps the formula stable….it is MUCH MUCH more that.

[Graillotion]

Keep the chelate for multiple reasons. Even MB’s making magnesium potions and lotions can and should use a chelate.

A chelate has varying affinity’s… and generally they prefer iron over all others. As you are well aware, mold struggles in an environment completely devoid of iron ions.

Yes…your chelate will become completely exhausted in your metal potion…but it will prioritize what metals it binds with first. This will also be enhanced with the order…..add you water portion and chelate…before you toss the other metals into the potion.

[Graillotion]

Thank you @chemicalmatt for dropping in and rubbing elbows with us earthlings.

I have made my first foray into the world of Salicylic acid…. which has in turn introduced me to a few ingredients that I had not worked with before.

The Sytheon rep mentioned it….as well as I had my eye on it for a while….just needed to be pushed.

Aloha.

great extra piece to be aware of!

@ozgirl without reading all 45 pages…. the coverage of that document…seems to be ‘organic’ and ‘natural’. Natural I completely agree with…. so you would still say…. ” organic zinc oxide” in not an acceptable term? Right?

[Graillotion]

Thank you for your research.

It is probably sold to them as…… “The trees that grow our ZnO have not been sprayed with synthetic chemicals or fertilized with toxic fertilizers. They were only grown in the presence of monks humming KumBaya.” 😉

[Graillotion]

Umh…..here in the US, that was not a conspiracy theory, but a vaunted agenda…under the name “No child left behind.” Where ALL children were left behind, in the name of the greater good, and goal of ignorance for all.

The results have clearly manifested throughout society now. The politicians realized that an ignorant constituency was far easier to control, than an intellectual one. You can imagine trying to control a society of intellectuals….it would be like herding cats! 😼

Aloha
