Hey wɔ hɔ! Sɛ́ obi a ɔde emulsifier ma no, wɔtaa bisa me HLB gyinapɛn ahorow a ɛwɔ emulsifier ahorow mu ho asɛm. Enti, momma yɛnkɔ mu pɛɛ na yɛnhwɛ sɛ emulsifiers ahorow wɔ HLB gyinapɛn ahorow ampa anaa.
Nea edi kan no, dɛn ne HLB? HLB gyina hɔ ma Hydrophilic - Lipophilic Kari pɛ. Ɛyɛ nsenia a ɛboa yɛn ma yɛte sɛnea emulsifier yɛ n’ade wɔ nsu ne ngo a wɔde afra mu ase. HLB nsenia no fi 0 kosi 20. HLB bo a ɛba fam (0 - 3) kyerɛ sɛ emulsifier no yɛ lipophilic kɛse (ngo - dɔ), bere a HLB bo a ɛkorɔn (17 - 20) kyerɛ sɛ ɛyɛ hydrophilic kɛse (nsu - dɔ).
Afei, sɛ ɛba emulsifiers ahorow so a, mmuae no yɛ yiw a ɛyɛ pintinn, wɔwɔ HLB gyinapɛn ahorow ampa. Na eyi yɛ super hia efisɛ HLB bo a emulsifier betumi akyerɛ ne mmɔdenbɔ wɔ application ahorow mu.
Momma yɛnhwɛ emulsifiers bi a wɔtaa de di dwuma ne wɔn HLB gyinapɛn ahorow. Emulsifiers a wonim no yie - no mu baako ne Span 20. Ɛwɔ HLB boɔ bɛyɛ 8.6. Span 20 yɛ lipophilic kɛse, na ɛma ɛyɛ kɛse ma nsu - a wɔbɔ wɔ - ngo (W/O) emulsions mu. Wɔtaa de saa emulsion ahorow yi di dwuma wɔ nneɛma te sɛ cream ne lotions mu baabi a wopɛ sɛ ngo no yɛ nea ɛkɔ so daa.
Ɔkwan foforo so no, yɛwɔ Tween 80. Tween 80 wɔ HLB bo bɛyɛ 15. Ɛyɛ hydrophilic kɛse, enti ɛyɛ pɛpɛɛpɛ ma ngo - a wɔyɛ wɔ - nsu (O/W) emulsions mu. Wɔtaa hu O/W emulsions wɔ nneɛma te sɛ salad dressings ne nufusu mu, baabi a nsu no yɛ ɔfã a ɛkɔ so.
Nea enti a emulsifiers ahorow wɔ HLB gyinapɛn ahorow no boils down to their chemical structure. Wɔde emulsifiers yɛ afã horow a ɛpɛ nsu ne nea ɛpɛ srade nyinaa. Saa afã abien yi nsusuwii na ɛkyerɛ HLB bo. Sɛ nhwɛso no, emulsifier a ɛwɔ hydrophilic kuw kɛse ne lipophilic kuw ketewaa bi benya HLB bo a ɛkorɔn, bere a nea ɛwɔ lipophilic kuw kɛse ne hydrophilic kuw ketewa no benya HLB bo a ɛba fam.
Nanso dɛn nti na ɛho hia sɛ emulsifier ahorow wɔ HLB gyinapɛn ahorow? Wiɛ, sɛ woreyɛ ade bi a, ɛsɛ sɛ wopaw emulsifier a ɛfata a ɛwɔ HLB bo a ɛfata ma w’ahiade pɔtee. Momma yɛnka sɛ woreyɛ aduru a ɛbɔ wo ho ban fi owia ho. Mpɛn pii no, nsu ne ngo nyinaa wɔ nnuru a wɔde bɔ nipadua no ho ban fi owia ho. Wohia emulsifier a ɛwɔ HLB bo a ebetumi ama O/W emulsion a ɛyɛ den sɛnea ɛbɛyɛ a owia aduru no bɛtrɛw ntɛmntɛm wɔ honam ani na ɛrentetew mu. Sɛ wopaw emulsifier a HLB bo a ɛnteɛ a, ebia emulsion no bɛbubu, na wo ade no rentumi nyɛ adwuma sɛnea wɔahyɛ da ayɛ no.
Ade foforo a ɛsɛ sɛ wususuw ho ne sɛ ɛtɔ mmere bi a, ebia ebehia sɛ wode emulsifiers a wɔde afra di dwuma na ama woanya HLB bo a wopɛ. Wɔfrɛ eyi sɛ emulsifier nhyehyɛe. Ɛnam sɛ wode emulsifiers mmienu anaa nea ɛboro saa a HLB botaeɛ ahodoɔ bɛka abom so no, wobɛtumi asiesie - nhyehyɛeɛ no nyinaa HLB. Sɛ nhwɛso no, sɛ wuhia emulsifier a ne HLB bo yɛ 10, na wowɔ emulsifier biako a ne HLB yɛ 8 na foforo a ne HLB yɛ 12 a, wubetumi afrafra wɔn wɔ dodow a ɛfata mu na ama woanya bo a wopɛ.
Afei, mepɛ sɛ meka ade bi a ɛyɛ anigye ankasa a ebetumi ama wo pii wɔ - nsɛm a emu dɔ mu afa emulsifiers ne wɔn sɔhwɛ ho. Wubetumi ahwɛ4-sɔhwɛdfgsdfg. Ɛwɔ data ne nhumu akɛse bi a ebetumi aboa wo ma woate emulsifiers ase yiye.
Sɛ́ obi a ɔde emulsifier ma no, mahu ankasa sɛnea ɛho hia sɛ wopaw emulsifier a ɛfata a ɛwɔ HLB bo a ɛfata. Yɛde emulsifiers ahorow pii a ɛwɔ HLB gyinapɛn ahorow ma de di yɛn adetɔfo ahiade ahorow ho dwuma. Sɛ́ ebia wowɔ aduan ho adwumayɛ mu, nnuru a wɔde yɛ ahosiesie, anaa adwuma foforo biara a ɛhwehwɛ sɛ wɔde emulsions yɛ adwuma no, yɛakata wo so.
Sɛ mprempren woreyɛ ade foforo anaasɛ worehwehwɛ sɛ wobɛma nea ɛwɔ hɔ dedaw no atu mpɔn a, emulsifier a ɛfata a wubenya no ho hia yiye. Na ɛhɔ na yɛba yɛn animdefoɔ kuo no bɛtumi aboa wo ama woapaw emulsifier a ɛyɛ papa a egyina w’ahiadeɛ pɔtee so. Yɛte ase sɛ ade biara yɛ soronko, na yɛasi yɛn bo sɛ yɛbɛma wo emulsifiers a ɛkorɔn sen biara - a ɛbɛma wo formulations no adi nkonim.
Enti, sɛ w’ani gye ho sɛ wubesua pii afa yɛn emulsifiers ho anaasɛ wowɔ nsɛmmisa biara a ɛfa HLB gyinapɛn ahorow ne emulsifier bɛn na ɛfata wo ho a, ntwentwɛn wo nan ase sɛ wobɛkɔ.
