"Umkhiqizo wethu ophendulayo ku-pH uqukethe ama-pigmenti e-thermochromic avulwa lapho uthintwa:"

IBromocresol green (0.2% concentration) ishintsha ivela ku-coral iye ku-rose pink (pH 5.4–6.2 range)
Microencapsulated D&C Red No. 27 iyanda ngokugqoka (4+ amahora okukhanya okwandayo)
I-Triethanolamine buffer iyagcina umbala wokugcina ukuze ihlale ihambisana ne-chemistry yemvelo ye-lip.
⚠ Isixwayiso Sokufaka: Faka kancane – umbala uthuthukiswa ngokuphelele phakathi kwemizuzu eyi-8 ukuze uthole imiphumela engcono.

2. Kungani le lip tint ingashintshi noma igxume njengezinye izinsalela?

"Inethiwekhi ye-polymer eyakha ifilimu (ethyl cellulose + acrylates copolymer) iqinisekisa ukunemba:"

Dala umkhawulo ongu- flexible emngceleni we-vermilion (ukuhlolwa kokwelula okungu-400% kudlulelwe)
I-Hydrogenated polycyclopentadiene igcwalisa imigqa ye-lip ukuvimbela ukuhlanganiswa.
72-hour humidity resistance (tested at 85% RH, 35°C)
💡 Iphuzu Elikhulu: Bhala imilomo nge-concealer kuqala ukuze uthole incazelo ecacile.

3. Ungagcina kanjani Umbala Ohlanzekile Imizuzu Engama-12+ Ngaphandle Kokuqhubeka?

"Ubuchwepheshe bethu bokuvikela i-oxygen buhlinzeka ngokwehla kokushiswa kwepigment:"

Ukufakwa kwePolymethylsilsesquioxane kuvikela imibala ekuthintaneni nomoya.
Ceramide NP (1.5%) ivimbela ukuwa okukhupha umbala
I-Glycerin-PEG/PPG blend igcina ukuvuthwa ngaphandle kokuxova ifilimu
✨ Key Insight: Gwema ukudla okune-oyili – umbala uhlala ungenasici kangcono ngemikhiqizo esekelwe emanzini.
