I don’t think Carbomer does cause the heaviness. I’m not sure if HEC would make it feel less heavy. It is just a suggestion on what you can try.
It’s difficult to make suggestions for your problem because there is so much unknown information. What do you mean by heavy? Have you done a knockout experiment to see what causes the problem? What else is in the formula? et.c -
What do you mean by NE? (do you mean New Emulsifier?)
You haven’t provided much information for anyone to give you a good response. Actual formula levels would be helpful. -
How do you know it is the Decyl Glyucoside causing the heaviness? More likely the thickener. You could try a Carbomer or maybe a Cellulose. (HEC)
-
Yes, the “for professional use only” line is a loophole in the regulations.
-
Hello,
You should add this information to the top discussion (need formulating services) -
Have you contacted the supplier of your silicone oil? Also, it would help if you posted your whole formula. Like @bobzchemist said lecithin will not work & we are more cosmetic chemists.
-
To answer a question like this you should provide the complete ingredient list. There may be something in the formula that you don’t realize is causing a problem but we might.

I don’t know much about the Rutgers program but the Fairleigh Dickinson program is taught by industry experts so you’ll get more cosmetic industry focus.
I know it looks great on a resume to have a degree from there and you’ll have the chance to make lots of networking connections so job prospects should be good.It ultimately depends on what your end goal is however. If you want to get a job as a formulator, you might be better off looking for a job now and get your company to pay for schooling. The online University of Cincinnati program is another good option. -
I know of no better way.
-
For most shampoos there is no reason to do separate phases.
-
Ah, one suggestion is to add the thickener to RT or cold water.
-
@Sarah - Thanks for the follow-up! That’s how everyone else will be able to learn.
-
@Bobzchemist - sorry just saw this post today. The one that @vitalys posted looks about the procedure we used at Alberto.
-
@DavidW - that’s the reality of the Internet. Fortunately, we have a loyal group that sticks around and more people joining every day.
-
Perhaps you could tell us what you are doing now. How do you add the thickeners & what is the procedure you are following to make your shampoo?
Typically, heating a batch up is a good way to remove bubbles. -
I think you are right, most people don’t have any opinion about parabens or even petrolatum. The reality is that the natural products niche makes up only about 10 - 15% of the cosmetic market. And most of those products are just greenwashed.
-
@nasrins - I don’t understand why hot water would make it harder to adjust viscosity. Wouldn’t you just heat it up then adjust your viscosity when you cool the batch down?
-
@Bimsmide - it depends on how the EO effects the CMC point of the surfactant. I’m not really sure there is a general rule but it’s probably more EO with increase foaming of laureth to a point. I’m not sure what that point would be.
@nasrins - Did you try hot water and high speed mixing? You might also try pre-blending it with something else like Glycerin or some other liquid in your formulation. -
Texapon is Sodium Laureth Sulfate. The ‘eth’ part of the Laureth refers to Ethlyene Oxide. The more EO in the molecule, the more water soluble.
TEXAPON N 70 NA - has an average of 2 mols of EO -
The term “active ingredient” in cosmetics is confusing. I agree with @DavidW that active ingredients are specifically ones that can support drug claims (At least in the US).
What most people call active ingredients I think of as “functional ingredients”. These are ingredients that actually make the product work. So functional ingredients in a cleansing product would be surfactants. In a moisturizer the functional ingredients are the occlusive agents, the humectants and the emollients.It can be confusing though. -
Our default expiration date for cosmetic raw materials was one year. At the one year mark the material would be re-evaluated for how well it matched specifications. If it was still good we would give it another year ’til expiration. However, in our company raw materials rarely stayed in inventory for more than a year. Only things like dye powders would last that long.

It doesn’t look like you have a polymeric stabilizer in there. That could be causing a problem. Try adding an Acryllic Polymer like Carbomer.
-
This really depends what you mean by stability. Plant extracts as sold to the cosmetic industry are stable. No amount of air exposure is going to change that.
Vitamins can be stable or not. Vitamin C is the one that can oxidize in the presence of air but the reality is that it probably oxidized before it was put into the packaging anyway. Topical application of even pure Vitamin C has little proven effect.Antioxidants? I don’t know. Again it depends on what you want the antioxidant to do. Superoxidedismutase isn’t going to do anything when delivered from a topical formula whether it was air sealed shut or not. Mostly antioxidants in skin creams are useful for keeping the formula stable but that’s about it. -
@nasrins - there are a number of different Carbomer grades so they are not all the same. See Lubrizol’s website for different grades and when you would use them. The Carbopol Aqua SF-1 should work for what you are trying to do.
