Active sulfactan calculation

I still confuse how calculate active sulfactan

Witch one is the right? 

For 1 kg formula.. use texapon np70 and use 100 gram of texapon
1. 100 x 70% = 70 - - - - > 70 /1000% = active sulfactan 7% or
2. 100x 0.27 (asm texapon is 27%) = active sulfactan 27%

Thanks

    @Eruio  you must ask your supplier if the SLES 27% active or 70% .
  • Use this to calculate active matter. Agree with Fekher, you should confirm SLES concentration.

    I look at the specification 
    Actual Matter (%) 70. 
    Inc name = SLS 
    --------------—
    The one that make me confuse is 
    1. From www.humblebeeandme/surfactans
    Said 29% 
    2. From www.itsallinmyhands.com
    Said how to calculate asm
    From the formula using sls is 29% =
     wt x active - - - > if i decide use 100gr - - > 100gr x 0.29 = 29
    3. But in one of blog in my country said to calculate the formula is 
    (Wt x active %) /1000% (1000gr) =70
    -----------—------------------------
    Lets we use same active number
    From web = 100 x 0.29 = 29 asm 
    From blog = (100 x 29%) / 1000% = 2.9 total active surfactan

    Which one the correct formula? 

    And i got jurnal formula in bangladesh
    The use total surfactan 56gr /1000 gr
    If we use callculation from 
    1. From Web they use 16.24% but if
    2. From blog they use only 1.624% surfactan

    @Eruio active surfactant=( % level of use in formulation * active concentration of  surfactant) / 100.
     So if you use 10 % SLS with 70% concentration
    surfactant active = (10 * 70) / 100 = (10 * 70 ) /  100 = 7%
