Absolutely agree with this. There are some so-so ideas out there with brilliant execution that are making lots of money.

No issues with preservation but it will probably depend on what preservative you choose.
-
We use that product normally in conjunction with Eumulgin SG (Sodium Stearoyl Glutamate) to make creams and lotions and make batches of 200 to 400L with no problems.
I seem to remember most of the starting formulations for that product included a second emulsifier like Eumulgin SG. I also think that the Emulgade PL 68/50 is referred to as an emulsion base rather than a complete emulsifying system so you may need an additional emulsifier to get good stability.

The biggest issue we have run into with tubes is being able to find low minimum order quantities when trying to purchase the printed tubes. The minimums are generally 5k to 10k.

Have you tried looking for a different supplier for your carbomer?
Just ask your suppliers if they have an equivalent for the product you are using.
Lots of raw materials are manufactured in Singapore so you may even be able to find one manufactured close to you.
-
I think the formula needs an emulsifier. It would appear that the formula is not really stable and destabilizes completely when you add the preservative.
Refer to Perry’s comments in this discussion for more info.
-
Have you tried putting the sodium carbomer in the oil phase?
We use a combination of Emulgade PL 68/50 and Eumulgin SG with sodium polyacrylate (all in the oil phase) and it works well.
I would second Bob’s suggestion to look at the Pemulens.
Also Euxyl PE 9010 can cause emulsion instability, so make sure it is not your preservative causing the problem.

You can pick scales on ebay quite cheaply. Look for scales that are designed for jewellery as these will often have more decimal places.
Also don’t forget your preservative.
Check out swiftcraftmonkey’s blog for some great information about making your own cosmetics.

I am not sure what you are trying to make either but it is important to convert your measurements to weight rather than drops. This will help replicate your products in the future.
-
Have you considered a semi-automatic labeling machine with your labels on rolls?
-
Stability testing at different temperatures will also give you an indication if your product will be ok during the temperatures encountered during shipping.

Congratulations!
-
When you refer to LAS are you referring to linear alkylbenzene sulphonate? If yes are you using the acid form and then neutralizing it and your lauric acid with sodium hydroxide or other alkali?
What is the surfactant level in your SLES?
Have you considered using cocamidopropyl betaine? It will improve mildness and help with viscosity and foaming.
What are you using to adjust your pH to 4-5? Why do you need the pH to be this low?

If you want to learn how to create products at home check out swiftcraftmonkey’s blog.

Also I would recommend that you sign up for Perry’s cosmetic formulating course.
It is unlikely that with no experience that you will be able to create a product that you can sell for profit. The reason you read about these success stories is that they are rare.
It takes many hours and months of formulating and testing to create a successful product. With no experience you will not be aware of all of the testing and regulations that are required to sell a product. So I would highly advise against trying to sell products until you have a solid understanding of the chemistry, formulating, testing and regulations.
Please don’t be discouraged about learning to create products just don’t think that this is an easy way to get rich quick.
If you are just looking for a product to sell then find a private label contractor and have them make products for you to sell.
Hope this helps

Lavender essential oil contains allergens and could be the cause of the problem.
-
If you add a flea control agent it could make your product a pesticide and it would be subject to pesticide regulations depending on your country.
Be extremely careful with any flea control or essential oils with cats as they do not have the liver enzymes to process these ingredients and it can kill them.
pH is also very important in animal products.
-
Maybe look at chicken egg incubators for a cheap way of testing stability if the products are only for your personal use. I am not sure what their maximum temperature is but I would imagine it is around 40-45 degrees Celsius.
Hope this helps

Congratulations on achieving your PhD.
I also have a PhD in Chemistry in an area unrelated to Cosmetic Science but I am currently working as a formulator/technical officer for a small company in Australia that specializes in cleaning chemicals with a smaller personal care / cosmetics division. So it is certainly possible to work in the Cosmetic Industry with a PhD in an unrelated area.
I personally think that employers don’t really care what area your PhD studies were in they just care that you have demonstrated the skills necessary to achieve the PhD.
Maybe doing an online cosmetic course like Perry’s would show employers that you are definitely interested in Cosmetic Chemistry.
Best wishes for your career!

Thanks for sharing!
You will notice that even though the parabens remain the most popular if you calculate the percentage of use this has decreased significantly because the amount of formulations investigated has increased.
It is interesting to see that the isothiazolinone preservatives are still increasing in popularity even with the concerns over irritation and allergy.
-
Thanks for the information. I will check out the availability of Rosamox here in Oz.
-
I would try premixing your essential oils with some Polysorbate 20 before addition.

The HLB system cannot be used for lactylate emulsifiers.
There is a system called LINDEX developed by RITA Corporation for lactylate emulsifiers.

@DavidW I wasn’t suggesting that you buy a detergent/shampoo and dilute it but just suggesting that you use one of your own basic detergent/shampoo formulas as a starting point.
Have fun!

Most of the “homemade” bubble formulas contain water, detergent and glycerin.
I would start with a standard detergent formula and dilute it and add some glycerin.
Sounds like some fun times ahead testing that formula.
