Ionic and Non-ionic surfactant
Skin care products and cosmetics need to add surfacant as well.
There are many types surfactants. They have different characters.
There are many types surfactants. They have different characters.
The surfactant could be divided into two
groups
1.
Ionic surfactant
The ionization has three types
Anionic surfactant
RCOO-Na+
RC6H4SO3-Na+
a. Cationic surfactant
RNH3+Cl-
RN(CH3)3+Cl-
b. Amphoteric surfactant
R+NH2CH2COO-
RN+(CH3)2CH2CH2SO3-
The Amphoteric surfactant is milder and fewer toxicities than
anionic surfactant. It most is made of shampoo and baby products.
2.
Non-ionic surfactant
water soluble functional group won’t ionize. It would exist as -OH,-
O-,- CONH-, -COOR types. It also could combine with different HLB values of
non-ionic surfactants.
RCOOCH2CHOHCH2OH
RC6H4(OC2H4)nOH
