Paprik - if you can tke the smell, with 9010 - mayte some Benzoate if the pH workand EDTA.  What’s the product

Ok, will search it up, thank you! ( And yes, I use EDTA ). 
Usually it’s a cream or serum. So pH around 5-5.5 if that suits my actives. But also trying to formulate facial cleansers now, where the smell doesn’t bother me at all. It’s mostly on leave on products.

I’m really struggling with getting a nice preservative. 
I’ve started with Liquid Germall Plus, but I’m afraid some of my customers won’t and don’t like the fact, that it’s formaldehyde donor. 
So was looking for something different. I found Euxyl PE 9010. I like it, but the smell is just nah. A new one I tried was Geogard Ultra TM (Gluconolactone (and) Sodium Benzoate (and) Calcium Gluconate), it’s a powder, seems to be super nice and easy to use, but it messes up with my pH. So I tried Microcare DB, seems also nice, it’s EcoCert, BUT the smell! So it’s hard to find one without any smell, “scary” names like Parabens or Formaldehyde and won’t mess up with my products. 

But as for me, I’m using Liquid Germall Plus the most. 
Also thinking about Naticide - but I know there’s a smell to it. And it’s expensive. 

What do you think about Potassium Sorbate & Sodium Benzoate? 

Certainly a wide range of anticipated levels of efficacy in your suggestions - mostly on the poor side.   Not knowing the product category -I’ll offer that you should assemble a combination of  preservatives (with a chelator like EDTA)  that SHOULD work and confirm with PET.  None of the sytems you desceibed are likely to be as effective as Germall Plus esp. vs Gram negative bacteria.  Organic acids require an appropriately acidic pH and are weak preservatives, esp re. Gram negative bacteria.  Natacide is a combination of unidentified (unknown?) “natural” materials.  Even if effective - you’re offered no assurance that batch to batch compostions will be identical to that you qualified. 
Why not use phenoxyethanol in combination?

Thank you for your reply. 
I am not surprised, that Germall + would be the best. However, if ppl find out, it’s formaldehyde release, they are like WHOOOOOW, slow down. Even those the input is really small and I believe it’s safe. 

Phenoxyethanol - what would you combine it with? I’m using Euxyl PE  9010, but I’m kind of annoyed by its smell.

I’m starting my Diploma in formulating soon, so hopefully I’ll know more and better soon

Hello guys,

I’m actually using FSH-2A. So I can share some thoughts. 
It is not bad. When I bought it, I wasn’t really happy. I thought, it’s introducing way too much air into my product. However, I learnt how to work with it. I don’t even use it on the highest speeed [It also gets warm very fast if used at max speed, so I’m scared to not burn it ] I’ve also made a really small batches. As 70 grams I think. Cleaning is easy, but annoying [probably with every homogen-head]. 
The heads are short tho. So I’ve head some problem, where tall profile beaker wasn’t the best for it. And the small head is not useful for me at all. I think I’ve used it twice and put it aside.  
Let me know if you would have any questions about that.

Hi Paigemsdavis,

I have started in my kitchen. Bought some stainless steel bowls, whisk, spatula, beakers, scale, ingredients and practiced, practiced, practiced.
Although, I wasn’t selling or giving this to my friends. I was afraid of contamination.
Once I had enough equipment ( I bought overhead mixer, homogenizer, better scale and waaaay more ingredients ) I have changed one of my small room into my small lab

Here is some information regarding formulating with SLMI that might help you with the SCMI.

Thank you for that Haven’t seen this leaflet yet, but found different ones.

What was the formula or just the ingredients you used?? 

That isethionate would be fine! It’s usually what you mix it with & pH that turn it opaque or white!! 

Did you use any aloe Vera? 

Hello Dr.,

thank you for your reply. Frankly, I was just trying to mix water, SCMI and CAPB. I just wanted to see how it goes. From top of my head, I used 8% SCMI and 4% CAPB. I did not even bother with any preservative. (I’m aware it may have an impact later on the formula.)

Next day I was trying add Glycerin and I adjusted SCMI to 10% and kept CAPB at 4%. Glycerin 5%. It barely thickened at all. So I guess I will need to play with the inputs of surfactants. 
And also check and adjust the pH. Althought, I would never imagine, it would go lower than 6 by itself.

I would also be interested in the difference between SLMI and SCMI. From the little information I’ve been able to find I believe they are fairly similar but don’t really know.

I don’t know about the slimy consistency, but what I do know is that the opaque opalescence of SLMI in water completely goes at a lower pH of around 5.

Hello Agate, 

thank you for your reply. Yeah, if I’m looking for SCMI, I always get results for SLMI. So I would also guess they must be very similar. Hopefully someone else will have more info about that

Hmm, so you reckon it would be the pH? I will try to increase it and see. Thanks for the tip!

Hello, 

what sunscreens are you talking about? 
Inorganic (physical) or Organic (chemical)? 

Organic absorbs the rays and converts them into heat. 
Inorganic does the same, but also reflects about 10%.

Hello,

hopefully my contribution will help little bit. 
About the pH - I think pH 3 is nearly self-preserving. Plus you have added preservative, so I think the high amount of PG is not really necessary. 

15% LAC is great, I’m using 20% myself. Although, some ppl may experience irritation, so starting with lower is better - Timeless Vit. C serum is 20% + E + Ferulic acid .. they say it may arrive cloudy, but it will turn clear over time. Check maybe their ingredient list and compare?  

Happy Formulating!

There’s an easy answer. SCI isn’t supposed to be used at aqueous products at any significant percentage to make it primary surfactant. It will precepitate.

Thank you for your reply. I really appreciate that.

Would you please recommend alternative to that? Or what would be the maximum of SCI in the formula to have is stable?
