@David Yes, I was producing nanoparticles from a nanoemulsion.

get out of there

great!
it is known that decreasing the size of the droplets or particles to the nano range one can create emulsions with low surfactant concentration (nanoemulsions). At laboratory scale one of the methods for producing nanoemulsions is ultrasound. Now they are able to apply that at industrial scale. I guess the droplet size is really tiny which guarantees the high stability. Amazing!

I would try to do this nice formulation with 0.2% Paraben at first. Thereafter I will do the stability test to prove if that paraben concentration is enough for the preservation of my product. If that is the case I will work at that concentration.
By the way, which kind of paraben are you using in your formulation?
-
Is it not better to reduce the concentration of Paraben to 0.2%?

Citric acid in combination with Sodium Benzoate will not lead to the formation of Benzene but you should be careful using Ascorbic acid and Citric acid in the same formulation, because Citric acid could accelerate the formation of Benzene. Even using Ascorbic acid and Sodium Benzoate in your formulation will not necessarily produce Benzene you will need additional conditions leading to the formation of Benzene.

I am formulating natural products. I am using a mixture of Benzyl alcohol, Benzoic acid, Sorbic acid and Glycerin as preservative. The mixture is called Rokonsal BSB-N. To use Rokonsal BSB-N as preservative system the pH of your product should not be higher than 5

I think you can use the two surfactants to make the emulsion. You don´t have to boil the mixture but you will have to apply vacuum in the homogenization process for better emulsion formation. Also you can increase the stability of the emulsion increasing the viscosity of the water phase. In my opinion oils can help to produce highly stable foam depending on their concentration in the formulation.
Give it a try

Yes, glycerine will be a good moisturizer

Hi Rahma,
If you are still looking for a chemist consultant for developing formulation for the hair care, please contact me. I started my own cosmetic brand Havana Curls and I also offering consultant services
Thank you

Thank you to all of you

In my opinion, if you are formulating for curly hair, the shampoo has to be somehow different. You have to clean but at the same time do some conditioner work. If you only clean and also remove all the oils from the hair you will not able to condition the hair with a 2 minutes rinse out conditioner in a proper way.

I am using natural oils in the formulation like jojoba. They are not producing hair build up and its composition is very similar to the sebum; the natural conditioner of the hair. In my opinion the cleaning process is easier when you don’t have hair build up, then you can use mild surfactants for cleaning the hair.

Thank you Robert,
Yes, I am using a cationic guar in the formulation. It is a challenge to formulate products for curly/dry hair. You have to clean the hair and at the same time to avoid to remove the natural oils from them (sebum). I am formulating a new kind of natural shampoo for curly hair. I am going even further until 5% oils content and the results are great. I know that is not so conventional but is something new
The curly hair market is not so researched and I would like to enter with new ideas

Hi,
I am formulating a natural shampoo for curly/dry hair with 3% of oils. I have obtained great results regarding applicability. I am using sugar/coconut based surfactants.
I think the emulsification process will be determinant for the stability of the shampoo.
What is your opinion about using 3% of oils in a shampoo formulation for dry hair?Thank you

Hi,
my name is Liset. I obtained my Ph.D in physical chemistry. I am the founder of Dr. Lüderitz Natural Cosmetics. We are developing high quality natural products for a niche market (The curly hair market). We are also offering consulting services. Our products are 100% naturals including the surfactants and the preservatives. They are produced and registered in Germany.
I like the interesting discussions in this forum and I would like to be part of that
