Alkyl sulfates and alkyl ether sulfates are made with varying amounts of

water. You can obtain 95% active material but it is very expensive. You are

correct in your math regarding the different actives levels.

sodium laureth sulfate questions.

Hello to all :)

I'm just wondering, I've been learning about

Sodium Laureth Sulfate, and that there are

different grades (if that's the right word)

depending on whether the raw materials have been

ethoxylated to 1 mole, 2 moles, or 3 moles....

If I understand correctly, the higher the number

of ethoxylation, the milder the SLeS?

What I don't understand, and this may simply be

to complicated to understand, is what

differentiates the types of SLeS that have the

same ethoxylation?

For example: Stepan has three sodium laureth

sulfates, all 3 mole. Each has different levels

of actives.... and Stepan suggests different uses

for each one? Are all sodium laureth sulfates (3

mole) about the same?

Can they be used for the same purpose?

And to see if I understand any of this correctly,

if you have SLeS at 28% active, and a SLeS at 56%

active, - example: a formula would call for

30%SLeS (3 mole, 28% active), could you sustitute

15% SLeS (3 mole, 56% active) ??

As always, any info deeply appreciated!!!

thank in advance!

cheers,

.
