Pamene umuna kuti ukwaniritse zofuna za Haptic kuvala nsalu, njira yokhotakhotayo kusewera ntchito yofunika. Wofatsa osiyanasiyana ndi kusankha kukhazikitsa kwa makasitomala ofewa, osalala, kukhazikika, komanso zina zambiri. Kugwiritsa ntchito mafuta ofewa ndi mafuta a silika ndikusintha kapangidwe kake ndi kusintha kwa generani kumatha kukhudza monga zofewa, chikasu, ndi madzi amadzimadzi mu nsalu.osadziwika aiimatha kuthandiza kusankha bwino kwambiri kwa masitayilo osiyanasiyana.

Kusintha kwa utoto ndi chikasu mu nsalu nthawi zambiri kumakhala kovuta pamaso pa gulu la Amino m'makanema ofewa ndi mafuta a silika. Makanema ofewa amatha kupereka dzanja labwino koma amakonda chikasu ndi banga, amakhudza hydrophilicity. Mwa kusintha makanema ofewa ofewa ndi mafuta a hydrophilic silicone mafuta kapena othandizira, chikasu amatha kuchepetsa ndipo hydrophicity yabwino. Makanema a Anionic kapena osakhala aluso samakhala achikasu ndipo amakonda kugwiritsa ntchito nsalu.

Kutsika kwa hydrophilicity ya nsalu kumatha kubweretsa chifukwa chofananira ndi mawonekedwe ofewa kapena kutseka kwamadzi. Sankhani zotupa za Anionic kapena osati kanema wofewa mogwirizana ndi mafuta a hydrophilic a silika. osadziwika ai amatha kuthandiza kuzindikira kanema woyenera kwambiri ndi mafuta a silika kuti asunge mtundu wa nsalu.
