Microformulation

In this Product, Polysorbate 20 is used for Tea Tree Oil. The Menthol was solubilized in the Alcohol. This would reflect in the grade of Carbomer and the fact that they use Triethanolamine as the neutralizer. 4% Menthol was achieved with the alcohol, but I don’t think this is an option with 15% net Menthol. This looks a lot like a Private Label product I have reverse-engineered from a specific retail supplier.

I took on an almost identical project several years ago. It is possible to “alter” the base, but in the end, it will be superior and less expensive in the long run to start from scratch. (In bulk it is less expensive to produce the base yourself, you can also ensure and validate that the other raw materials are diluted, etc.)

The Rotor/stator will do the trick on the floor. I once saw a plant try to hit it as hard as they could with Lightnin’ Mixers with no luck.It was a while ago, but I believe that we added some of the fluid to create a slurry before homogenizing the final product. You are absolutely right. I had a Lab Tech hit it dry with a silverson. She was cleaning for a long time to get it all.

In the lab, it is easy to compensate for water loss by using the predicted weight of the vessel/product and accounting for the water loss. On the floor, it requires that the water loss be extrapolated in process scale-up. (An educated guess).Now, to be more precise, in manufacturing this factor is rarely monitored unless it is a Formulation that is fairly brittle in this regard. At 80C and with covered tanks, it is less significant than you may believe.

Don’t attempt it without a real lab homogenizer such as a Silverson or in manufacturing an in-line homogenizer. I did several products with that technology, including a Powder to Cream self-tanner. It can be tricky by Evonik offers a great deal of technical support in their documentation.

Are you using DHA? If so, that is the likely issue. The distributors offer guidance on how to best work with DHA (pH, metallic ions). A chelator helps, but not because it stops pH movement. That is not what a chelator does. It would help by decreasing metallic ions. Remember, EDTA in a no-no as far as chelators go.

It doesn’t matter what the “biz” people want. Organic has a legal definition in the US. It means the product is compliant and manufactured under the USDA NOP Cosmetics program. To call a product Organic otherwise is false advertising.
-
@Pharma I agree completely!

No offense, but how would a W/Si emulsion be Organic?
-
No offense intended. It is normal that you are initially exposed to sources that espouse “natural” and “chemophobia.” As you get deeper into the subject, especially if you formulate (Formulators shouldn’t sell and sellers shouldn’t Formulate IMHO), you will start to see a great deal of misinformation. If you use a source as a reference, my advice is;
- Ensure that they have footnotes to reputable Journal sources.
- The Author has valid credentials.
- The source is not selling a product as this is a conflict of interest. “Is the information they passing true education or are they trying to sell you a product?”

How are those preservatives”toxic?” What is their LD50? Benzyl alcohol is an irritant, not really “toxic” per se.Not picking on you, but you need to balance “story” (“natural”, “Organic”) with cost and performance. A great product is well balanced.

Is that Chemist an independent Formulator or does he work at the Contract Manufacturer? Oftentimes a CM will Formulate for these low prices (I will not) but you a. get this price only if you manufacture with them as well and b. you do not own the Formula (IP), they do. Read the contracts closely.
-
1. Find a place to make a larger scale batch (a contract manufacturer)Exactly. Unless you have good experience in Cosmetic manufacturing, do NOT manufacture yourself.

The subscription service at UL Prospector has all these functions. It is $9 a month I believe.

You are asking for a lot of free info. What have you researched on your own yet?
-
It is a marketing agreement with little to no effect on the hair. In addition, I think you will see that adding it will raise the cost per ounce of your product to a noticeable extent. It can be expensive.
-
^^^This. You need a preservative. Unless you have tested the product your feeling that it is safe is just a feeling. TTO is not a preservative. Rosemary is an anti-oxidant, protecting the oils from oxidation but not from bacterial growth.

There are numerous moisturizers out there that are W/SI based as well as numerous starting Formulas. If you look at the “natural” markets you will see much less of these products. Silicones are practically idiot proof and have outstanding qualities.

Silicone-based emulsions have great skin feel and are generally well-received by clients looking for performance. One could almost state that we are “chasing” this effect with our “natural” emulsifiers with emollients.
