Absolutely Amazing!

I was struggling to find a natural preservative to use in my face masks because I was having a lot of issues with molding of my clay face masks and I found GEOGARD ECT and it works amazing. No scent not issues and a small amount goes a long way to preserve the products. So happy with this product and the company shipped fast, no issues with receiving product. Will be buy this again for sure!

Geogaurd ect

With having a small skin care line that I manufacture I found geogard ECT as a incredibly versatile and cost-effective preservative as you all can use it in amount as low as. .5% total volume. The pH is incredibly broad so you don’t have to worry about it potentially falling out of protection if you’re product has dropped to low into the acidic rang or too high into the alkaline range it mixes incredibly easy it doesn’t really have an odour and it has some extra skin softening benefits so for me it’s my go to now just to prevent any potential mould or mildew formation on my products which I’ve tried to keep as clean and natural as possible

Geogard ECT vs Germall Plus

It's a great choice for those with sensitive skin. In comparison to Germall Plus this is definitely a better choice. The downside is it reduces the PH of your product by half and has a very strong smell to it that will affect the smell of the product.
