SUICEL, the dry mask fabric can absorb and store moisture about 9-40 times of its own weight ( not including moisture absorbed by the protective material/ backing material ). Therefore, there are 2 important tips you need to pay attention while preparing essence for the sheet masks.
It takes abundant moisture for the dry mask fabric to restore its 3D structure and recreate its designed functions:
The weight of one SUICEL “Super Absorbent Permeation Membrane” dry mask is 1 gm, thus it requires at least 10 to 15 ml of water to fulfill its film structure and form the shape. A regular size of SUICEL “Super Absorbent Cavernous Membrane“ dry mask also weights 1 gm and roughly about 15 to 30ml of water or more is required for shaping the mask.
To adjust proportion of water in product formulation:
The dry mask must capture most of the water from the formula base to form the 3D reticular structure; the reduction of water base will lead to the change of percentage saving for other ingredients and increase serum viscosity. In order to maintain relative concentration of the other ingredients, texture and viscosity for the remaining serum, it is necessary to increase proportion of water in the serum. Therefore, SUICEL Super Absorbent Permeation Membrane dry mask in comparison to regular non-woven fabric face mask needs at least 10 to 15ml of water in the serum base, and on the other hand SUICEL Super Absorbent Cavernous Membrane dry mask needs 15-30ml of water or more to fulfill its 3D reticular structure.
When the proportion of water in the serum is moderate, the mask will turn soft, moist, and transparent and remains a high intensity. When the proportion of water is too low in the formula, the mask will become too hard and dried and is difficult to adhere to the face skin. Meanwhile, the remaining serum can be too thick and very sticky. Contrarily when serum is too watery, the mask might become too fluffy and fragile to apply on. All of the situation above could attribute to the material base used for making SUICEL as it carries ions.
For example a piece of SUICEL Super Absorbent Permeation Membrane dry mask contains 0.02 grams of potassium chloride and each SUICEL Absorbent Cavernous Membrane dry mask contains 0.03 grams of potassium citrate. Therefore, when any of the product needs abundant water as its formula base (more than 40 ml for example), a proper amount of potassium ion (potassium citrate or potassium chloride) will be a necessity adding in the essence to maintain concentration level of potassium ion at about 0.05-0.2%, and the overall water ratio to the mask weight should be limited within 80 times less.
3.Mask base membrane model and folding type ：
Research finding,when the mask model has an opening in the eyes and mouth position and folds the eyes or mouth outward,Elliptic marks and even holes were found in a few membrane bodies.The reason is that after folding the membrane body ,the bare base membrane immersed into the essence directly.As a result，the local ion concentration of the membrane decreased greatly and the melting burst was broken.
①The face mold USES a face shape with a slit at the mouth.
② Fold the exposed parts of the eyes and mouth inside.
③ Potassium ion can be added to the essence,If the first two solutions can not be adopted or if they are adopted,there are still traces，Potassium ion can be added to the essence Super absorbent permeation membrane can supplement 0.05%-0.2% potassium chloride into the essence. Super absorbent cavernous membrane can supplement 0.1%-0.3% potassium citrate in the essence. It is suggested to make sample debugging according to the actual situation of the essence.
Temperature of the essence might cause breaking down of the mask structure. Thus, it is important to keep temperature of essence lower than 60 Celsius degree to avoid mask degradation when filling essence into the bags.
Storage condition for SUICEL:
Dry and confined space at room temperature; away from direct sunlight.
The quality standard for manufacturing SUICEL is in line with the” Technical Specification for Cosmetics Safety (2015)”. In order to ensure high quality for the finished products, further physical and hygiene safety tests and inspections on the dry sheet masks need to be performed before mass production.
