Microformulation

@Gunther One distinct difference in the two materials is the fact that the PEG-8 Dimethicone is water soluble whereas they amodimethicone is not. The PEG-8 Dimethicone allows you to deliver some of the effects of a silicone in the aqueous partition.

@ngarayeva001 PEG-40 Hydrogenated Castor Oil is a very common solubilizer and is a workhorse in many markets. In my experience, it is much like Coconut Oil and will become solid or wax-like in cooler environments. This doesn’t affect the performance of the product. I will routinely place these type if ingredients into a beaker in a 40C water bath and they quickly liquify.

@Belassi There is a lot of money being invested into the Medical/Recreational Cannabis product lines. I have heard of companies buying this product, the analytical testing equipment and the equipment to do supercritical extractions all at one time PLUS hiring good staff.This company makes some smaller units. At 1200 watts it is faster and more effective. But as you have pointed out, it is easy to overpower the unit and burn out the probe.

@globalwidget Be sure to tip your waitress.

If used correctly, they are much better at producing the microemulsions. As you can see in that manual, you can set-up a lab-top production set-up.It is a huge advantage for some accounts, in the fact that they may have limited technical staff on-hand and the companies provide staff training and the surfactant bases needed.Now, that doesn’t mean they don’t screw-up. The biggest issue I have encountered is people over-heating the bar-bell probe and either burning out the probe of “scorching” the microemulsion. The fails of these processes have a very distinct “scorched” smell.This Technology has been around for a while. Several years ago at a plant, I worked at we got a Heischler (another system) on loan. We didn’t use it for microemulsions but for sunscreens.

Comodenicity is one of those concepts which is taken as gospel initially as people begin Formulating. I believe that this arises since many “crafter sites” will post these numbers as if they are absolute and correct. As you progress and learn more, you see the issues with these numbers and the market applications, you will use these numbers as a rough guide, not an absolute measure.I would avoid going down the Oil “SPF” rabbit hole. The SPF levels assigned are low and if you read, it is based on 100% of that oil. So, for example, an oil might have an SPF of 3, but that is not directly assignable. Lastly, this approach is not approved by the FDA. I would step back carefully and evaluate any claims as such.Some oils are lighter and have different properties. It will become a matter of experience with the materials OR if your marketing does not limit your material selection, step up to the Emollients and Silicones and do it right!

@Sheng I would contact the supplier (whom I found online) and ask for an ingredient list. They should be able to provide this.In my experience, looking at the ingredient list at this point is the most effective solution. Oftentimes when you break the ingredient deck down, how the achieved the effect is immediately obvious.

I fixed the graphic (which I borrowed from a website and was not my work product) to be nicer.

@Dtdang I have seen that study presented at a conference. They did a small scale study on an animal model and never went any further with human studies. In fact, the presenter was asked about the properties as an anti-bacterial and the presenter stated, “We have not yet studied that” and stated that in no way were they saying that the oil has these activities in humans.

Here is the website (already on the Suga Det Mild page) https://www.colonialchem.com/sugadet-mild/If you peruse the sell sheet https://www.colonialchem.com/fullpanel/uploads/files/sugadet-mild-tds.pdf it lists a simple starting Formula with the Suga Det Mild.Colonial is a larger more mainstream company, so they may not send samples to accounts they have not evaluated (business as usual) or tiny accounts. If that becomes an issue, Formulator Sample Shop repackages and sells the Suga Det Mild as well.

@Fekher The Dunning-Kruger effect does not suggest stupidity but rather describes a logistical fallacy where we become “experts” in the subject matter almost immediately. I used a graphic I pulled down to illustrate the learning curve so the syntax was already in the chart.Let me describe the logistical fallacy in a parallel situation that I like to call the “Psych 101” scenario. I, like many who took a Science curriculum, had to take Psych 101 and 102. Well, Psych 101 throws you into the theory. Early in the semester, all of the students, myself included, suddenly thought we were “experts” and started to “diagnose” each other. By the end of the year and Psych 102, we evolved to see that we were hardly experts.This is a common logical fallacy and one that I have even seen highlighted at conferences. The point is not to show you are “stupid” but rather to illustrate this fallacy can be a barrier to Professional growth as initially, when you should be learning fundamentals, you are suddenly an expert. In my experience, I have also seen it be a barrier to someone developing the fundamentals since “why do I need to read entry level articles? I am an expert!”My best and honest advice is to engage in a directed study into the Industry, read about materials, read about Product Development and hundreds of other topics. Many of us are “arguably” experts, particularly in some niche. However, despite this, I still read 4 Journals cover to cover a month. I learn something new every day. MY POINT IS if you don’t realize the knowledge gaps (we all have them) you can not grow.This is reflected in some statements. When you look at the structure of Ceteareth-25, read the sheets and research the material, you will see that the material is not molecularly structured to provide conditioning and/or surfactant system thickening. The statement, “I am innovating” is not revolutionary. but rather misguided.That is about all I can say. I do see a spat above and some distressed syntax. As a rule (especially since the last election), I proactively avoid any online back and forth. In this case, I simply stand on the Chemistry and the value of identifying logical fallacies which can affect one’s Professional Development.

Is that for the STANDARD? I see the proposed Formula. I am looking for the ingredient deck for the original standard.
-
On many of the product pages, they have Formulas listed. They also will send you other available Formulations if you contact them.

If you posted the ingredient list it would be more helpful to those who could weigh-in.

All this is why there are so many grades of Carbomer. They have some that are specifically more electrolyte resistant.I have been able to thicken True strength (1X) Aloe with the right grade of Carbomer and the proper neutralizer. Knockout of the park.As for the efficacy of Aloe, there are all sorts of opinions, many from anecdotal data as well as a few cited studies I have read. This may sound bad, but regardless of what it does, my clients ask for it and it poses no real issues in the Formulation or Procurement. I have no issue with it in a gel or an emulsion. Honestly, if it works is debatable, but it is all marketing.Is this wrong? No, since every day in the lab, averaging 2 prototypes a day, I use a handful of raw materials I think possess real effect and the rest is bunk. Nature of the Market.

“engineer should be creative?” That doesn’t change the Chemistry and is likely one of the statements most steeped in the Dunning-Kruger effect I have seen this quarter.If the Chemistry is wrong and the properties are not there it is not the correct choice. There are nearly hundreds of better raw materials. Hundreds.“chemist fit the square peg in round hole? Should be creative.”

Coco-Glucoside is actually non-ionic, a distinction from amphoteric. This is where the Chemistry comes in.
-
Colonial Suga Det Mild. They even have a starting formula as you described on their company website.
-
Ceteareth-25 would not be on my list for a shampoo product. I can think of a legion of other products that really would have conditioning and thickening properties?
-
@DtdangThat is a pretty serious piece of equipment, not something a beginner or an at home Formulator would ever use. It was really more for Belassi’s benefit.
-
Again, Decyl Glucoside. Read ^^Still an issue.

The general feeling is that all the Alkypolyglucosides have some sort of irritation potential. It is less with many, but in some cases, I have lines avoiding the APG’s entirely now.Ocular irritation should never be “postulated.” If you are going to make this claim, it should be tested with HET-CAM at a minimum.
