Faʻatasi ai ma le faʻaauau loloto o le atinaʻe ma le faʻaogaina o suʻesuʻega o surfactants, o lona tulaga lautele o loʻo faʻalauteleina foi. I le taimi nei, surfactants ua avea ma autu vaega o detergents, ma e tele foi a latou aoga taua i mea teuteu, pei o le faʻamalosi, faʻasalalauina, solubilizing, foaming ma le faʻamamaina o cosmetics.

1) Faʻamamaina

O le vaʻaiga o le faʻamalosia tutusa o le le faʻamaloloina o le vai i totonu o le vai e fausia ai se emuliona ua taʻua o le emulsification. Emulsifiers e masani ona faʻaaogaina i le gaosiga o kulimi ma kulimi i mea teuteu. O le masani pauta kulimi ma kulimi le faʻaituau e lua 0 / W ituaiga emulsions, lea e mafai ona faʻamalosia ma anionic emulsifier fatty acid fasimoli (fasimoli). E faigofie ona saunia emulsions ma laʻititi suauʻu e ala ile emulsification o fasimoli, ma le gelling aafiaga o le fasimoli mafai Faia ia i ai se sili atu viscosity. Mo kulimi malulu o loʻo i ai le tele o suauʻu, o le emulsions e tele lava i le ituaiga W / O, ma le natural lanolin ma le tele o le suavaia o le vai ma le maualuga o le viscosity e mafai ona faʻaaogaina mo emulsification. I le taimi nei, o le sili ona lautele faʻaaogaina le-ionic emulsifier o le le-ionic emulsifier e saogalemu ma e maualalo le itaitagofie. O le lauiloa sorbitan fatty acid ester (Span) ma lona ethylene oxide adduct (T pagitan) e lelei tuʻufaʻatasia e le ionic emulsifiers. Span o le lipophilic ma le Tantara o le hydrophilic, ma o le lua e fefiloi. Faʻaaogaina i le O / W emulsions, e mafai ona fausia ai faʻamalosi tino ma le mautu lelei ma le maualuga o le paʻu.

2) Solubilization

O le faʻaaliga o le faʻateleina o le solubility o laʻititi soluble poʻo insoluble vailaʻau e taʻua o le solubilization. A o le surfactant e faʻaopopoina i le vai, o le feteʻenaʻi luga o le vai o le a pa'ū matuitui i le taimi muamua, ona faʻatutuina ai lea o le micelles o surfactant molelaʻau. Ole faʻatosina ole surfactant na faʻaaogaina e fausia ai micelles e taʻua ole micelle concentration taua. A oʻo le vaega o le surfactant i le taua tele o le micelle concentration, e mafai e le micelle ona mitiia le suauʻu poʻo ni vaega maopoopo i le tasi itu o le lipophilic base, ma faʻapea ona faʻateleina ai le solubility o le teʻa soluble poʻo le insoluble mataupu.

Solubilizers i cosmetics e masani ona faʻaaogaina i le gaosia o kulimi, lauulu vailaʻau, ma lauulu vailaʻau. Surfactants faʻaaogaina solubilizers tatau ona maualuga hydrophilicity, HLB> 15, e pei o polyoxyethylene faamaʻaina castor suauʻu, polyoxyethylene castor suauʻu, gaʻo ava malosi polyoxyethylene ether, gaʻo ava malosi polyoxyethylene-polyoxypropylene Eteru, polyoxyethylene sorbitan fatty acid esterty ma polyglycerin etc.

O mea gaʻo gaosi i mea teuteu, e pei o mea manogi, suauʻu, ma vitamini e mafai ona soli i le suauʻu, e iai ituaiga eseese e mafai ai ona solubilization ona o le eseʻesega o le fausaga ma le faʻaleagaina. O le mea lea, surfactants talafeagai tatau ona filifilia o solubilizers. Mo se faʻataʻitaʻiga, o mea solubilization o le kulimi o mea manogi, suauʻu ma vailaʻau, ma isi, o lea alkyl polyoxyethylene ethers mafai ona faʻaaogaina mo solubilization. E ui lava o le alkylphenol polyoxyethylene ethers (OP type, TX type) e malosi le solubilizing agavaʻa, o loʻo tiga i latou i mata ma e masani ona le faʻaaogaina. I se faʻaopopoga, castor suauʻu-faʻavae amphoteric mafuaʻaga maua sili solubility i suauʻu manogi ma fualaʻau suauʻu, ma ia surfactants e le afaina ai le mata ma e talafeagai mo le sauniuniga o le soʻona faʻasasaina shampoos ma isi cosmetics.

3) Faʻasalalauina

O le mea e tupu ai le vai-e le mafai ona faʻatupuina ni mea i se tulaga tutusa faʻataʻapeʻapeina i totonu o le vai ua taʻua o le faataapeapeina. O le faʻataʻapeʻapeina faiga o teuteuina aofia ai vaega e tolu: efuefu, solvent ma faataapeapeina. E mafai ona vaevaeina le efuefu i ni ituaiga se lua: pigment inorganic (e pei o talc, mica, titanium dioxide, carbon black, ma isi) ma pigment organic (e pei o le phthalocyanine blue, ma isi), mafuli lava ina ia cosmetics i ai se lelei lanu lanu, mafai ufiufi le lanu i tua, ma ia lelei faʻaaoga Solvents e vaevaeina i ni ituaiga se lua: vai-faʻavae ma leai-vai. Faʻasalalauina faʻaaoga e pei o ala o faʻasalalauga o hydrophilic (faʻatatau i vai vai) ma lipophilic (faʻatatau i le le-vai vai faiga). O le mea lea, o le faiga e tele faʻatasiga.

Tele surfactants faʻaaogaina i dispersants o emulsifiers ma dispersants uma, e pei o le gaʻo ava malosi polyoxyethylene ethers, sorbitan gaʻo gaʻo esers, gaʻo ava malosi polyoxyethylene ether phosphates, alkyl ether carboxylates ma alkyl ethers. Sulfonates, ma isi mea, latou uma lelei lelei faʻasalalauina meatotino. Ina ia mafai ona faʻasalalauina atoa le pauta i le vai, e tatau ona mafai e le suavai ona faʻasusu lelei luga o le pauta. O le mea lea, pe a filifilia se surfactant, muamua mafaufau i le HLB o le paʻu luga ma le faʻasalalauina auala. O le mea e masani ai, pe a faʻaaoga le lipophilic powders i le vai-based system, e tatau ona faʻaaoga tele le hydrophilic surfactants.

4) Faʻamamaina aʻafiaga

O oloa a le tagata lava ia e faʻaaoga mo le fufuluina e masani lava ona aofia ai le shampoo, shower gel ma foliga fufulu mama. I le faʻaopopoga i le faʻamamaina, foaming ma moisturizing gaioiga, o le autu manatu i le taimi nei o le agamalu i le paʻu. Lenei manaʻomia le surfactant le faʻaleagaina le epidermal sela, e le afaina ai le paʻu polotini, ma e le ulu i totonu pe ati i totonu o le paʻu. Ia tausia le paʻu suauʻu ma le paʻu lava ia i se tulaga masani.

Anionic surfactants ua i ai se umi talafaasolopito o le faʻamamaina. O le vailaʻau o le fasimoli e le mafaatusalia e isi vailaʻau. Sodium lauryl sulfate o se mea e masani ona faʻaaogaina i le faʻamamaina o mea teuteu, e mafai ona faʻamalosia ai le paʻu i se faʻamama lelei. Amphoteric surfactants, imidazoline, cocamidopropyl betaine ma amino acid o loʻo faʻamamaina uma surfactants faʻamama, ma o ni vaega taua mo le sauniuniga o le maualuga-iuga foliga faʻamamaina foliga, lauulu tausiga shampoos ma pepe shampoos.

5) Faʻamalulu ma antistatic aafiaga

Cactic surfactants o le autu conditioners i lauulu faʻamamaina oloa e pei o conditioners ma conditioners. Latou maua lelei agamalu ma antistatic agavaʻa ma faia se tulaga ese matafaioi i lauulu faʻamaluluina conditioners. Le sili ona masani faʻaaogainacactic surfactants o monoalkyl ma dialkyl quaternary ammonium masima, e faʻapea o le C16-18 monoalkyl ammonium salts, faʻalua C16-18 alkyl quaternary ammonium masima ma alkylbenzyl quaternary ammonium masima. Asymmetric maualuga,octyl dimethyl quaternary ammonium masima ma le 3-cetyl methyl ammonium salt, o nei masima amonium masima o loʻo i ai ni aafiaga lelei i le mamago selu, susu selu ma le faʻamamaina o laulu. Talu ai nei, o le sili ona mataʻina-mata o le quaternary ammonium masima maua mai lanolin fatty acid. E le faʻaitagofie ma ei ai le vai faʻatumauina ma wetting meatotino o lanolin ma uiga ocactic surfactants, lea e mafai ona faʻamama ai lauulu ma tutasi tutoʻatasi pei o le vaivai.

6) Faʻasusu ma goto i totonu

I le avea ai ma mea teuteuina, e tatau ona le gata i le lalelei o latou aafiaga, ae ia lagona foʻi le mafanafana ma le agamalu pe a faʻaaogaina. Nei e le mavavaeeseina mai le susunuina aafiaga o surfactants. I lenei itu, biosurfactants ua ausia faʻamanuiaga matagofie. I le avea ai o se vaega taua o sela o meaola, o le phospholipids e taua tele i le sela metabolism ma sela e faʻatonu ai le suamalie o le membrane, ma e lelei le taofiofia o le susū ma faʻafouina le paʻu o le tagata. Sophorolipid biosurfactants maua se uiga vavalalata uiga ese mo le paʻu, lea e mafai ona faia ai le paʻu vaivai ma susu. O le faʻaaogaina o le biochemical synthesis ma isi metotia e sauniuni ai meaola aoga o le biochemical ma vailaʻau o loʻo maua mai ai, sauniuniga o le enzyme, sela tuputupu aʻe sela (EGF, DFGF), collagen, elastin, ceramide ma hyaluronic acid, ma isi mea, o nei vailaʻau mafai ona faʻaaogaina i mea teuteu. Ulufale i totonu o le paʻu, auai i le metabolism o paʻu sela ma aano o le tino, suia le fausaga o paʻu o aano o le tino, ma isi mea, ina ia mafai ona ausia le aafiaga o le aneti-maanuminumi, aneti-matua ma papaʻe.
