Without my notes which are in my office I would day try 1% sodium citrate to start. Mic it into water first and make sure it totally dissolves.
Again, not to be rude but until I know what type of product you are making and your other ingredients I won’t be responding to this anymore. It would be a waste of time to throw out all different possibilities when most may not apply.

You never know what will end up clear till you try. Experiment with the emulsifiers and you will learn a great deal.
However if you try to put too much oil into a shampoo, it may start off thick and a few weeks later you could have the consistency of water.

Well, suggestion really depends on the type of product and other chemicals you can use.
PEG-400
SLES if you heat it first
Add sodium citrate to your water first will help solubility
Adjusting pH up will help depending on what your final pH will be
SD alcoholThere is a start for ya.

^^^ What he said above

You made a sample for them over a year ago and now they are contacting you to tell you this? You have no idea how many times they opened and closed this or what conditions their sample was held in. Too many variables to tell. Can they take a good, close, clear picture to send to you that you can post? Crystallization to them may actually be something else. Have you seen it?

I am not aware of alcohol based fragrances if you are buying from fragrance manufacturers. Depending on how much alcohol it can thin your shampoo and cut down on foaming. I would just use your essential oils or “off the shelf” fragrance oils. You will have to premix them with something most likely to make them soluble. Don’t use to much oils or your system could end up thinning out over a few weeks time.

Try using polyquaternium 10 at about 0.5% instead of the Incroquat. See how you like it. maybe also add something similar to Jeesilc 94 (Amodimethicone and Trideceth-12 and Cetrimonium Chloride) at 2 to 4%. First try polquat alone or Jeesilc alone so you can see the difference.

Wow Mark, you wrote half a book. Are you bored? LOL
@Jon_R I have been in this industry for 28 years. We develop, manufacture and package all kinds of anti-aging and have done so for many high-end and multinational companies. If you are interested send me your contact information and I will get in touch. The deposit fee for development of such a high end product is going to be $2,500. After our discussions and I have a better idea of exactly what your project will entail we will let you know what the total cost for development of your product will be. There is no charge for discussions.

Would be helpful to know what type of product it is going into.

@bobzchemist Thank you very much for the info Bob.
-
@Bobzchemist Thanks for the reply Bob. No, customer did not stipulate that it need to be organic. I appreciate any info you can give me.
-
@Sarah thank you

Look in the pinned posts. You’ll find some there.

Are you asking which is better, to go with a consultant or a cosmetic laboratory?
Without a list of ingredients for a product, if it is possible to break down a formula it is going to be VERY expensive and time consuming and probably not complete. But, everything from this country has a list and a chemist will be able to use his/her best guess based on years of experience. If they are good they will get so close you won’t know the difference.

Thanks Holden & Matt for the replies . This stick is going to be a line of products for use on the face and and 2 of then under the eyes. One for puffy eyes and one for dark circles. The customer wants them in a round propel/repel stick that holds about 1oz. The only thing I could think of to formulate the base was based on a deodorant stick.
Menthol is out because customer doesn’t want the smell and under they eyes it may irritate the eye. Frescolat (Menthyl Lactate) didn’t give any feeling. I have a sample of Cool Act 10 that we may try.Holden, years ago someone gave me a sample of something for tightening. I couldn’t remember what it was but I have been calling all my suppliers asking. Now that I see it, it is the Interpolymer product you mentioned. Thank you very much. I am going to get a sample of that.
Oh, and for tightening I also tried something from makingcosmetics.com called Skint Tight AP which works in creams or serums but not giving the effect in the stick. Below is the base of the stick.
Off the top of my head it is about:
Water 40%
Propylene Glycol 25%
Butylene Glycol 12%
Sodium Stearate5%
Not sure what else. -
Thank you both for your replies, appreciated.
-
Glad it worked out for you.
-
I would suggest looking in the pinned thread where there are some people who list their services.
I would also suggest you look in this forum for @microformulation and @bobzchemist
They are both very good and may be able to help. We used to have more on here like Duncan and others but I don’t know what happened to them. -
What else do you have in your formulation?
-
Yes, we are fortunate in that respect.
-
Regardless of how you put it together. Over time (like over night) all the bubble show be gone.

You have to weigh the cost of grad school against the debt you may incur vs future earnings. You may be better off seeking out small or very small manufacturers and offering services for free or minimum wage. I think in a small or very small company you may have success in getting hired as a tech. Even cleaning glassware for the chemist will enable you to be around the lab, ask questions, watch and learn.
Also, in the mean time maybe becoming a DIY formulator will give you real life experience. There are many websites to get info from on this. There is also a FB page on the subject where people ask for and get advice. The lady who is the admin for the page is great. Very knowledgeable and helpful.

Also see: http://makingskincare.com/Starting as a DIY making things in your house will give you experience. At least then a small company will know you can at least properly weigh chemicals, follow batching instructions etc..

Let people ask anything they want. We don’t have to answer
