SLSA vs SCI

[madmel]

Hi Creatives

Is there much difference between SLSA and SCI?

I'm thinking of switching to SCI for my bath bombs and bubble bars, but need to know if there is a huge difference in performance

For my syndet shampoo bars i can't use more than 6% SLSA without it making my scalp itchy (and I'm not usually sensitive to much). SCI I can use at up to 55%.

Wow...that's a big difference
Does it lather up the same as SLSA?

I'm not sure. I've always used them together, just the ratio was higher until I realised that the SLSA was causing the itch, so I reduced it.

SCI lathers well in the products I have made.

What I would do, if you don't already have some, buy a small amount of SCI and experiment. Wherever you've been getting your SLSa, should also have SCI. Important: you'll want the powder, not the noodles, since for this application the noodles aren't ideal (they don't dissolve in water easily without being abraded, i.e. being rubbed on a wet washcloth/flannel or on wet hair).

You'll want to make one with SLSa, one with SCI, and a few with varying ratios of a mix of both. Keep in mind, the other ingredients in your products will affect its ability to lather, so if you still aren't getting the mountains of foam you're after, you can look into your other ingredients to see what you can tweak to maximize foam.

And as always, as KiwiMoose already brought up, there are maximum limits for every ingredient. Check with the vendor or manufacturer to make sure you aren't exceeding safe limits.
