Formulating

Decyl Glucoside

How can heaviness from Decyl Glucoside in a Facial cleanser be removed.

The Cleanser consisting of Decyl Glucoside and Betaine is thickened by Aculyn 22 and Salt, visocosity is very low, but consistency is heavy.

There are not a lot of other ingredients in the formula except Water extracts!

Any thoughts? Any other recommended Thickener in this kind of system?

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)

Thanks Perry,

I just never thought of Carbomer being a culprit as I have used it with different surfactant and havent felt the same.

Is there a reason why HEC would be less heavy than Carbomer? Just curious.

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

I think he is referring to the initial slimy feel of the polymer and hence the cleansing effect sets in after the intial slimy feel disappears. Better use a different thickener if you want to avoid that feel, I have experienced it with Aculyn 22 and Carbopol Aqua SF 1 both.

Simple test - try the APG and the betaine without the aculyn or salt - is it still “heavy”?

Potentially, you might have your surfactant levels too high.

for being nonviscouse:
The salt can viscous your
cleanser if u use ionic surfactants in formula such as SLES. but decyl glucoside is nonionic, so it doesn’t work( betain produces onions too but not as much as SLES) .

Aculyn 88 is viscosity
modifier but in facial cleanser its better to use carbomer (in my opinion). And
why u don’t neutralize your polimer cause after neutralizing viscosity is increased again.

Well, Now I know the source of onions ) ) )

@ vitalys u know I dont have any problem to giving basic information…if you have you can ignore it….

@nasrins,

You said “betain produces onions too but not as much as SLES” Did you mean ions or anions?

@vitalys, if you’re going to tease, it looks like you need to point out the source to prevent misunderstanding…

@Bobzchemist, No, no teasing ! I didn’t mention anything but funny word combination and I didn’t expect any misunderstanding. I’m sorry if the kidding caused such misunderstanding

Bob I meant anions… and I dont care what vitalys said. Im just here for learning more and more.

pH would decide the nature of Betaine (an amphoteric), and since the pH is below 7 generally for facial cleansers I suppose it would be more of a positive charged ion. But if the pH is above 7 then yes it would be anions.
