Bitewe n'iterambere ry'imibereho y'abantu no kunoza imibereho yabo, abantu barushaho kwita ku kubungabunga uruhu rwabo n'isura yabo. Guhitamo amavuta yo kwisiga ntabwo bikigarukira ku bikoresho byo kwisiga bya buri munsi nka amavuta yo kwisiga, amavuta yo kwisiga, n'amavuta yo kwisiga, kandi icyifuzo cy'ibikoresho byo kwisiga birimo kwiyongera. Amavuta yo kwisiga ashobora kunoza vuba kandi neza imiterere y'uruhu rw'umuntu n'uko rusa. Ariko, dioxyde de titanium, mica, ibintu bikora filime, toner n'ibindi bikoresho fatizo biri mu bikoresho byo kwisiga ntibikinjizwa n'uruhu. Byongera umutwaro ku ruhu, bigatera ibibazo nk'uruhu rudakomeye, imyenge minini, ibiheri, ibara ry'uruhu, ibara ry'uruhu rituje, nibindi, bigira ingaruka ku buzima n'isura y'uruhu.

Hari ubwoko bwinshi butandukanye bw'ibicuruzwa bikuraho kwisiga ku isoko, nk'amazi akuraho kwisiga, amata akuraho kwisiga, amavuta akuraho kwisiga, imisatsi ikuraho kwisiga, nibindi, kandi imikorere y'ubwoko butandukanye bw'ibicuruzwa bikuraho kwisiga iratandukanye, kandi ingaruka zo gusukura kw'ibicuruzwa byo kwisiga nazo ziratandukanye.
Hashingiwe ku bunararibonye bw'umwanditsi mu bushakashatsi n'iterambere ry'imyaka myinshi, iyi nkuru iragaragaza uburyo bwo gukuraho amavuta yo kwisiga, ihame ry'uburyo bwo kuyakuraho ndetse n'uburyo bwo kuyatunganya.
Amavuta 50-60%, amavuta akoreshwa cyane ni amavuta ya isoparafini, polyisobutylene ya hydrogenated, triglyceride, isopropyl myristate, ethyl oleate, ethylhexyl palmitate, n'andi. Amavuta ari muri formula ashobora gushonga ibikoresho fatizo bishongesha amavuta mu bicuruzwa bisigaye byo kwisiga, kandi akagira ubushyuhe bwiza kandi afite intungamubiri kugira ngo uruhu rutoshye nyuma yo gukuraho kwisiga.
Surfactant 5-15%, surfactants zikunze gukoreshwa ni anionic na nonionic surfactants, nka polyglycerol oleate, polyglycerol stearate, polyglycerol laurate, PEG-20 glycerin Triisostearate, PEG-7 Glyceryl Cocoate, Sodium Glutamate Stearate, Sodium Cocoyl Taurine, Tween, Span, nibindi. Surfactants zishobora gukurura ibikoresho fatizo bishonga mu mavuta n'ifu idakora mu bikoresho fatizo bisigara bifite amabara meza. Ikora kandi nk'umusemburo w'amavuta n'ibinure mu bikuraho kwisiga.
Polyol 10-20%, polyol zikunze gukoreshwa ni sorbitol, polypropylene glycol, polyethylene glycol, ethylene glycol, glycerin, nibindi. Bikozwe nk'ikintu gihumeka.
Ibyimbishwa 0.5-1%, ibibyimbishwa bikunze gukoreshwa nikarubomeri, aside acrylic (ester) / C1030 alkanol acrylate polymer ifite ihuriro ry'ibinyabutabire, ammonium acryloyl dimethyl taurate / VP copolymer, aside acrylic hydroxyl Ethyl ester / sodium acryloyldimethyl taurate copolymer, sodium acrylic acrylic copolymer (ester) na sodium polyacrylate.
Uburyo bwo gukora:
Intambwe ya 1: gushyushya no gukurura amazi, surfactant ishonga mu mazi na polyol humectant kugira ngo haboneke icyiciro cy'amazi;
Intambwe ya 2: Vanga emulsifier y'amavuta n'amavuta kugira ngo habeho igice cy'amavuta;
Intambwe ya 3: Shyiramo igice cy'amavuta mu gice cy'amazi kugira ngo uvange neza kandi uhindure agaciro ka pH.
