Performance test

ⅠExcellent Foaming property

1,The foaming property of SLG in different PH value

As the pH value increase,the foam volume of SLG solution increases first,then decreases.It has excellent foaming property in extensive pH value.Especially in the condition of pH=5.5±0.5 weakly acidic,its foam performance is the best.And the pH value is similar to human`s skin,making skin more comfortable and soft.

2,Compare with other surfactant

SLG compares with other anionic surfactant,it shows better foams performance,foam are moderate.SLG is more suitable for face clean personal care product.

3,Temperature effect of foam stability between SLG and traditional surfactant

When pH=6.0,at different temperature,compares with other anionic surfactant,the half foam life period of SLG is longer.Foam is more stable.

Ⅱ Mild selective cleansing ability

1,comparison of SLG and sodium laurate skin cleaning effect

    Skin before clean

After SLG clean                                        after sodium laurate clean

Compare with sodium fatty acid, the degreasing ability to the skin is significantly lower and milder.

2,Selective cleanliness

SLG minimizes the removal of moisturizing ingredients from the skin while ensuring that oils are removed.

3,Toxicity test

                                                                                                  SLG is much less cytotoxic than other conventional

	petroleum base anionic surfactant.(The higher half lethal dose, the less toxic it is.)
