The flakes or white powder have about 65% active SLSa with a pH of about 6.3, which is perfect for our skin and hair products. There is moderate skin irritation at 70%, but we don't use levels that high, so consider this a mild cleanser.
SLSa is an excellent foaming, bubbling, and lathering surfactant. It offers great cleaning and detergent properties.
I use this product in foaming bath bombs and in shampoo bars as the white powder, and in a ton of other products like facial cleansers, body wash, and shampoo as LSB (which is SLSa and disodium laureth sulfosuccinate). It's a great inclusion in foaming bath salts as well.
Some people find SLSa makes their hair feel crunchy when used in a shampoo bar. If you're one of these people, consider using extra moisturizers and conditioning agents in a shampoo bar to eliminate this sensation. Or substitute something like Bioterge AS-90 (C14-16 olefin sulfonate, powdered) for SLSa, which offers great foam and cleansing, but the bubbles aren't as great as SLSa.
When you're using this product, make sure you wear a mask. It is composed of fine particles that get into your nose and mouth, which is seriously unpleasant!
