@student54 I don't know a lot about hair, but according to my little understanding, hair is negatively charged and therefore you need a cationic compound to produce a conditioning effect.

@David08848 To get ungated as a skin-care manufacturer they ask any of the following: FDA registration, GMP certificate, or a certificate of analysis. For the GMP, they want from a third-party inspection service. For the COE, I don't know exactly w…

@Zink Can you share what the COA included? I assume microbial and chemical. Although, I don't know what type of chemical analysis would be enough to satisfy Amazon's requirements. Thank you

You could use retortable pouches. These pouches can be sterilized in a retort using overpressure. Google "retortable pouches" to get acquainted with the technology. This probably would be more feasible than aseptic processing.
-
Few thoughts about this. * When canned, food products with a pH above 4.6 are sterilized, which means the product is heated to temperatures around 121oC for a certain time. If the pH is below 4.6 the product can be pasteurized at temperatures below …

@Wolf For finished products you need to contact a lab that specializes in cosmetic product analysis. The reason is that there are specific protocols for cosmetic products. For any product that contains preservatives, as cosmetics do, the preservativ…

I wonder if there is a patent somewhere for this mask. I searched on the USPTO and found nothing.

When selecting a viscometer make sure to pick one designed for the range of viscosities found in cosmetic products. Brookfield offers 3 series: LV, RV, and HA/HB. Cosmetic applications normally fall in the LV category.

pH is probably high because it has been adjusted by addition of base.

Olivem 300 is not an emulsifier. It is an emollient.

@MarkBroussard There are no many packaging options for shower scrubs. Most shower scrubs contain sugar--or other big particles--so it is not something you can put in a bottle with a pump or in a standard tube. I've seen tubes with a big orifice that…

@Margreat Both, lard and tallow contain up to 50% of unsaturated fats, mostly monounsaturated. Lard can have up to 10% of linoleic acid. This is why reheated pork in most cases releases a characteristic off-flavor that in the industry is known as &q…

Yes, jars are a problem. Most of them are tapered and there is no way around if you use rectangular labels. However, there are many pumps and treatment pumps that do not have a taper.

@CC7 I did a lot of experimentation on printing my own labels and got some good results. Color laser printers don't work. I used an HP Jet Pro 400 M451, which is a very good office printer. It prints well on weather proof polyester labels, but the c…

Also gluconolactone gets converted into gluconic acid when dissolved in water, which may help to drop the pH

@Belassi You deactivate the enzyme by increasing the temperature to the denaturation temperatures. After that, you normally don't separate the denatured enzyme from the hydrolyzate. It could be done, but it is too expensive. Besides, the level of en…

Proteins are better hydrolyzed with enzymes. It is a less harsh and more consistent process. You can use HCL and then neutralize with NaOH, but you end up with a lot of salt in the hydrolyzate that in many cases can be a problem.

Try this: http://www.yourboxsolution.com/ They do short runs at a reasonable price

@ botanicalsecrets Did you try to copy and paste your pictures? I just tried and worked.

I think the sodium lactate is the cause of you problems with pH reduction. Do you really need it at 2%? Sodium lactate comes from a strong base and a weak acid, so when dissolved in water will give you a basic pH. Also you have protein, which may be…

Assuming your have the right column, mobile phase, detector, method, etc this is what I would do. I would prepare one formula with your compound and one without your compound, run through the HPLC and then overlay the chromatograms. if you see tha…

In fats and oils, fatty acids are not present as free acids, but as triglycerides. Inevitably, some free fatty acids are produced during the extraction process due to hydrolysis, which is something the industry tries to minimized because high concen…

@ Belassi I'm just curious. Do you get any effect at 0.25%?
-
@MarkBroussard Do you get your preservatives directly from Schulke? I assume they sell only large quantities.
-
The reason I asked is because all the information on the web indicates that emulsifying wax NF, including Polawax, is an emulsifier. All the sites that sell small quantities of ingredients list E-wax as an emulsifier and most homecrafters use E-wax …
-
I tried to edit, but it was too late. What I meant about emulsifying wax NF was other brands of e-wax
-
@Bobzchemist. What is Polawax used for in cosmetic emulsions? Skin feel? texture? What about emulsifying wax NF?
-
Did you use a hand mixer or a stick blender?
-
For lotions, I let them cool to room temperature before bottling.

If you plan to use it as an antioxidant I'd think you need the reduced form
