Engredyan yo nan krèm men yo ak krèm jeneral swen pou po yo fondamantalman menm jan an; Yo ka klase yo an jeneral nan kat gwoup prensipal: akeuz-engredyan faz, lwil-engredyan faz, emulsifyan, ak lòt konpozan.
Lwil-Engredyan Faz
1. Idwokarbur: Squalane, lwil mineral, petrolatum, sir parafin, elatriye.
2. Lwil natirèl / Grès: lwil oliv, lwil oliv zaboka, lwil zanmann, lwil nwayo abriko, lwil mayi, lwil jèm ble, lwil oliv primrose, elatriye.
3. Pi wo asid gra: asid stearik, asid palmitik, asid laurik, asid myristik, asid oleik, asid isostearik, alkòl isostearyl, elatriye.
4. Pi wo alkòl gra: alkòl cetyl, alkòl stearyl, alkòl cetearyl, alkòl oleyl, kolestewòl, elatriye.
Fonksyon prensipal kat kategori engredyan ki anwo yo se bay tendres ak lubrisite sou po a; fasilite absòpsyon po a nan medikaman ak engredyan aktif; pou fòme yon fim lwil oliv idrofob; idrat po a; anpeche evaporasyon imidite; diminye friksyon; amelyore ekla po; ak ede nan netwaye po a.
5. sir: sir myèl, lanolin, sir carnauba, sir candelilla, sir jojoba, sir parafine, sir mikrokristalin, elatriye.
Engredyan sir prensipalman sèvi kòm ajan solidifye pou amelyore estabilite pwodwi; bay pwopriyete reolojik ak efè thixotropic; amelyore eksperyans sansoryèl ak efè amolyan; ogmante pwen k ap fonn faz lwil la; ranfòse fim nan idrofob sou sifas po a; ak bay pwodwi a yon fini briyan.
6. Ester sentetik: IPM (Isopropyl Myristate), IPP (Isopropyl Palmitate), Caprylic/Capric Triglyceride, Isostearyl Neopentanoate, Pentaerythrityl Tetraisostearate/Tetracaprate/Tetracaprylate, Oxalates, Pentaerythrityl Stearate, Dicapryl, Dicapryl, elatriye.
Ester sentetik prensipalman fonksyone kòm amolyan, amelyore gayabilite pwodwi a, lubrisite, kapasite idratan, ak rèspirabilite; yo ede tou nan mouye ak dispèsyon nan poud ak pigman, sèvi kòm solvang pou lwil oliv -konpozan idrosolubl ak sir, ak amelyore santi a po jeneral nan pwodwi a.
7. Lòt moun: Dimethicone, Cyclopentasiloxane, Cyclomethicone, elatriye.
Engredyan faz akeuz
1. Humectants: Glycerin, Propylene Glycol, 1,3-Butylene Glycol, Polyethylene Glycol, Sorbitol, Dipropylene Glycol ak dérivés li yo, Asid amine, Asid laktik ak Sodyòm Laktat, Sodyòm PCA, Methyl Gluceths, Panthenol, Chitin dérivés, elatriye.
Fonksyon yo gen ladan idrate stratum korne a, amelyore santiman sansoryèl, ak solubilize engredyan dlo -idrosolubl.
2. Dlo -idrosolubl Polymers: Xanthan jansiv, Guar jansiv ak dérivés li yo, Alginates, Hydroxyethyl Cellulose, Carbomer, Acrylamide / Sodyòm Acryloyldimethyltaurate Copolymer, Aluminosilicates, elatriye.
Yo sèvi kòm ko-emulsifyan; bay efè dispèsyon ak sispansyon pou amelyore estabilite; kontwole reoloji; amelyore santiman sansoryèl; epi ofri benefis idratan.
3. Dlo -idrosolubl Lipid: Trigliserid Ethoxylated, Di-PPG-3 Myristyl Ether Adipate, PEG-40 lwil Castor, PEG-60 Almond Glycerides, PEG-42 Babassu Glycerides, elatriye.
Yo aji kòm solubilizer ak ko{0}}emulsifyan nan sistèm O/W; yo kontwole viskozite pwodwi ak amelyore santi po pwodwi a.
4. Alkòl ki ba -kabòn: Etanòl, Alkòl Isopropyl.
Yo kapab solubilize lòt engredyan ak reglemante viskozite.
5. Dlo.
Emulsifyan
Fonksyon prensipal emulsifyan se fasilite emulsifikasyon sistèm losyon an epi ajiste valè HLB sistèm lan.
Lòt Konpozan
1. Alcalins/Bases: Potasyòm Idwoksid, Sodyòm Idwoksid, Triethanolamine, Aminomethyl Propanol. (Itilize pou ajisteman pH.)
2. Konsèvatif: Methylparaben ak Propylparaben, Imidazolidinyl Urea, Polyquaternium-15, Asid Benzoik, elatriye (Premyèman sèvi yon fonksyon anti-bakteri.)
3. Antioksidan: BHT, BHA, -Tocopherol, Ascorbyl Ester, elatriye (Anpeche ak anpeche oksidasyon pwodwi.)
4. UV Absorbers: Benzophenone-5, Ethylhexyl Methoxycinnamate. (Pwoteje pwodwi a kont ekspoze UV)
5. Chelating Ajan: Disodium EDTA
6. Ajan Tanpon: Asid Citric-Sittrat Sodyòm, Asid Laktik-Laktat Sodyòm (ajisteman pH)
7. Ajan koloran
8. Parfen ak odè
9. Ajan famasetik ak engredyan aktif
