Ka'idar Fasaha ta Anti-Frizz a cikin Shamfu
Ba kamar na'urar sanyaya gashi ba, shamfu abu ne da ake amfani da shi wajen wanke gashi cikin sauri wanda ke da ɗan gajeren lokaci. Saboda haka, fasahar hana bushewar gashi a cikin shamfu galibi ta dogara ne akan tsarin adanawa mai wayo - sinadaran sanyaya gashi suna mannewa a gashi koda bayan sun kurkure. Wannan fasaha galibi ana gina ta ne daga:
1. Tsarin surfactant mai laushi don tsaftacewa mai daidaito.
2. Polymers na gyaran gashi na cationic waɗanda ke manne da gashi mai caji mara kyau.
3. Silicone (misali amodimethicone) ko madadin da ba na silicone ba don tasirin zamewa da laushi.
4. Man shafawa da lipids/esters don kiyaye ruwa da rage bushewa.
5. A kula da pH (yawanci ɗan acidic) don sanya cuticle ɗin ya yi tsauri.
6. Sinadaran da ke tallafawa kamar su masu kauri, abubuwan kiyayewa, da ƙamshi waɗanda suka dace kuma suka dawwama.
Babban Sinadaran da Matsayinsu
1. Masu Tsaftacewa (Masu Tsaftacewa)
Shamfu mai hana frizz ya fi kyau amfani da haɗin surfactants don ƙirƙirar isasshen ƙura amma ba da yawa ba:
– Anionic surfactant (babban mai tsarkakewa): misali Sodium Laureth Sulfate (SLES) ko wani zaɓi mai laushi kamar Sodium Lauroyl Sarcosinate.
– Amphoteric surfactant (mai laushi da kuma mai daidaita kumfa): Cocamidopropyl Betaine shine misali mafi yawan gaske.
– Nonionic surfactant (laushi da narkewa): misali PEG-7 Glyceryl Cocoate ko glucosides.
Manufar ita ce a cire mai da datti ba tare da barin gashi ya bushe ba kuma ya haifar da ƙwanƙwasa.
2. Sinadarin Kwalliyar Cationic
Sinadaran cationic polymers suna manne da gashin da ke da ƙarfin caji mara kyau, wanda ke taimakawa wajen rage tsayuwa da kuma ƙara zamewa. Misali:
– Polyquaternium-10 (sau da yawa ana amfani da shi saboda yana da karko da kwanciyar hankali a kan gashi)
– Guar Hydroxypropyltrimonium Chloride (wanda aka samo daga cationic guar)
Wannan polymer yana taimakawa wajen "ɗaukar" wasu kayayyaki (misali, silicone) don a iya ajiye su cikin sauƙi.
3. Tsarin Silikon da Tsarin Hana Rage ...
A fannin fasahar hana bushewar gashi, silicone ya shahara saboda yana samar da siririn layi wanda ke laushi saman gashi kuma yana rage yawan shan danshi. Amfanin da aka saba amfani da shi sun haɗa da:
– Amodimethicone (yana mannewa sosai ga sassan gashi da suka lalace don haka ba ya da nauyi sosai)
Yawanci ana amfani da silicones tare da emulsifiers da "abokan hulɗa" na cationic kamar Trideceth-12 da Cetrimonium Chloride a cikin nau'in emulsions da aka shirya don amfani.
Idan kana son wanda ba silicone ba, wasu madadin sune:
– Masu laushin esters (misali, sigar isopropyl myristate mai dacewa da gashi, ko kuma esters na musamman don kwalliya)
– Wasu man kayan lambu a cikin ƙananan yawa (argan, jojoba) tare da bayanin cewa dole ne a narke su don kada su rabu.
- Masu shirya fina-finai kamar wasu nau'ikan polymers waɗanda ke ba da sakamako mai santsi
Duk da haka, tasirin da ya fi dacewa na shamfu masu kurkurewa cikin sauri shine mafi girma fiye da na tsarin silicone da aka ajiye sosai.
4. Man shafawa da kuma abubuwan da ke sanya danshi
- Glycerin ko Propanediol suna taimakawa wajen kiyaye danshi.
– Panthenol (Pro-Vitamin B5) yana taimakawa jin cewa gashi ya “cike” kuma ba ya bushewa.
Ya kamata a daidaita shi domin yawan sinadarin humectant a muhallin danshi na iya sa wasu gashi su ji kamar sun yi laushi—don haka sinadaran hana yin humectant galibi suna daidaita humectant tare da sinadarin emollients/film formers.
5. Maganin Daidaita pH da Chelating
Shamfu masu hana bushewa gabaɗaya suna da pH na 4,5–5,5, wanda ke taimakawa wajen matse ƙusoshin da kuma laushin gashi. Bugu da ƙari, abubuwan da ke hana bushewa kamar disodium EDTA suna taimakawa wajen ɗaure ions na ƙarfe daga ruwan tauri, wanda zai iya barin gashi ya ji kamar ba shi da laushi da kauri.
Misalin Tsarin Tsarin (Misalin)
Ga misali na tsarin tsari (ba girke-girke na kasuwanci na ƙarshe ba) don shamfu mai hana frizz:
- Ruwan da aka cire daga ion: har zuwa 100%
