Emulsion
بالبدايه لازم تفرق بين الذوبانه
والانتشار(dispersion)الي هو يمشي عليه emulsion
الذوبانيه يعني يذوب كامل ميبقى منه شي
الانتشار يعني تضل جزيئات منتشره بالمحلول بدون متذوب بيه
خنفهمك سالفه...
اتخيل انو سلة جبيره بداخلها تفاحات قليله .... التفاحات تمثل ال internal phase الي جوه والدائرة الجبيره تمثل external phase ....
ف انتي خلي قانون بالك
Internal/external
اذا جان ال water هو الدائره الجبيره يعني external وال oil هو الدائرة الزغيره ف يصير القانون ك تالي
Oil /water
والعكس صحيح ..
هذا بابسط صوره ال emulsion تختصرلك سلايدين
اما بخصوص purpose
باوع خنتفق على شغلة انو ال external هي الي نتذوقها من ناخذ emulsion وكذلك هي الي تمتص ال internal مالها دخل
ف خنسولف عليهن خطوه خطوه
من تشرب شراب كحه
تحب تشربه ك سائل عادي(ماي)لو زيت
اكيد متروح تشرب زيت ؟
ف شنو النوع الي يفضل
O/W
وعرفتو منو external ومنو internal
وهاي خلص سلايد 3
ال factors حيل مهمات احفظهم
يكلك يمتى نستخدم o/w او w/o بالاعتماد على عدة عوامل (احفظهم)
هسه نجي ع تفسيرات من خلالها تفهمهم
🔵اذا جانت w/o منو الطبقه الخارجيه الي تواجه الامتصاص وكلشي ؟
الزيت اكيد
ف هو يكول جلد غير مكسور أو مجروح ف نستخدم الزيت لان اذا استخدمنا الماء اول ميتعرض لماي او يطيح ماي عليه حينزال ف الدهن لا ماينزال بالمي لان ميذوب بيه وكذلك انو طبقة الجلد الخارجيه بيها طبقة اسمها sebum هاي الطبقه تكون دهنيه ف يذوب بيها الدواء الدهني أكثر ...
ويكلك اخر شي اذا تريد انو مستحضر تكدر تزيله من الجلد ف بكل سهوله تستخدم O/w الي هو ابو الماي...
