Natria Lauroil Metil Isetionato & Natria laŭrosulfoacetato

La Diferencoj Inter Surfactant SLMI kaj SLSa Pulvoro

1) Vezika aspekto :
Natria Lauroil Metil Isetionato(SLMI)

Large and small bubbles
Rinses easily
Creamy foam feel
Tacky skin feel

Natria laŭrosulfoacetato(SLSa)

Tre bone, stable bubbles
Creamy foam feel
Skin not dry

2) Surfactant foam
Ŝaŭmanta: initial foam height cm

Foam stability: Ŝaŭma alteco/komenca ŝaŭma alteco (%) post 5 minutes The influencing factors for stabilizing the foam system Viscosity of the system (liquid phase viscosity), the viscosity increases, the stronger the foam performance, the lower the drainage capacity
Shaking foam test (0.2% active solution at 25°C)

SLMI: 300 cm without oil, 260 cm after 5 minutes SLSa: 360 cm without oil 340 cm after 5 minutes

SLMI: with oil , 260 cm 5 minutes later 245 cm SLSa: with oil, 260 cm 5 minutes later 245 cm

3) Surfactant mildness
Test zein test, which is a test of the degree of effect of surfactants on living proteins.

The less protein dissolves, the milder the surfactant, Test the irritation of surfactants with zein Take SLS as an example, its zein value is 100

Sodium lauryl sulfoacetate SLSa: 58

Natria Lauroil Metil Isetionato SLMI: 55

4) PH:
Natria Lauroil Metil Isetionato(SLMI) :4.8 Natria laŭrosulfoacetato(SLSa) :7.0

5) Active Substance :
Natria Lauroil Metil Isetionato(SLMI) : 76% Natria laŭrosulfoacetato(SLSa) :80%
