Description

Dry biodegradable PLA mask pack manufacturing method with excellent transfer effect and its products {PLA MASK PACK AND PREPARING METHOD THEREOF}

The present invention relates to a biodegradable PLA mask pack, and more particularly, while utilizing a plant-derived PLA (Poly Lactic Acid) material that is not harmful to the human body and the environment, various components impregnated in PLA sheet paper are transferred to the skin layer to improve whitening and wrinkles. It relates to a method of manufacturing a dry biodegradable PLA mask pack, which has excellent effects such as moisturizing, and has excellent transfer effects that are naturally degraded upon disposal, and its products.

In general, disposable mask packs are widely used as cosmetic packs that moisturize, remove dead skin cells, and supply nutrients by attaching gauze or nonwoven fabric moistened with lotion to the face and removing them after a certain period of time.

Recently, regulations on the use of disposable products are accelerating in Europe and Korea in accordance with policies to reduce environmental pollution and greenhouse gas (CO2), and most mask pack sheets are made of chemically synthetic nonwoven fabrics or products containing chemically synthesized short fibers such as cotton and Korean paper. .

In addition, in the case of manufacturing a plant-based cellulose sheet, the cellulose or pulp sheet has a problem in that the price is expensive due to the difficult chemicals and manufacturing process during manufacturing.

Since such a conventional mask pack is manufactured by a wet method, a manufacturing process is difficult and storage is difficult. In addition, since moisture can cause various bacteria, it is bound to contain additives such as preservatives.

In addition, sheet paper such as pulp, cotton, and cellulose has a high moisture absorption rate, so it is difficult to transfer to the skin layer because the sheet paper absorbs various raw materials, and there is a problem in that it is difficult to make makeup after using a mask pack due to oiliness on the face due to the oil component.

[Step of producing amorphous biodegradable PLA nonwoven fabric]

PLA material is brittle due to its brittle properties, and it is difficult to produce low weight (40g/㎡) due to its weak tensile strength. It may fall off due to weak adhesion. In order to solve this problem, when producing PLA spunbonding nonwoven fabric, the screw temperature is set to 230℃, but amorphous biodegradable PLA nonwoven fabric of 40g/m² or less is produced by passing two pressing rolls to make it amorphous.

Among the pressing rolls, the embossing roll is 140°C to 150°C, and the remaining rolls are 50°C to 60°C. In order to reinforce the strength of the long-fiber PLA fiber spun here, if the temperature of the embossing roll among the pressing rolls is below 140℃, the PLA resin does not melt and the tensile strength of the spunbonded nonwoven fabric is weakened. It can be crystallized, and PLA fibers can be crystallized if the temperature of the rest of the general rolls is 60°C or higher.

As described above, an amorphous PLA spunbonding nonwoven fabric is produced, but the weight used in the mask pack is 20 to 40g/m2, preferably 25g/m2. Here, if the weight is less than 20g/m2, it may be a problem when impregnating various components, and if it is more than 40g/m2, adhesion to the face may decrease.

[Step of producing purified water containing various ingredients]

Various ingredients can use ingredients that comply with the regulations of the Ministry of Food and Drug Safety, and a mixture of two or more such as extracts such as herbal extracts, vegetables, fruits, grains, medicinal plants, aquatic products, and fermented food and cosmetic ingredients such as soybeans and soy milk. Use.

Here, various ingredients are whitening essence that suppresses the production of melanin in melanocytes and removes melanin that has already formed and deposited to make the skin white and transparent and blemishes, an anti-aging essence that restores elasticity and relieves wrinkles through skin protection, and suppresses sebum secretion and inflammation. The sebum normalizing essence that keeps the skin dry and smooth by preventing the creation of skin blemishes, moisturizing essence, sensitive essence that soothes sensitive skin, wakes up the skin in the morning, supplies moisture and vitamins, and soothes at night. Booster essences are used to increase the absorption power of the main treatment.

The ratio of various components is mixed with 95 to 90% by weight of purified water in a ratio of 5 to 10% by weight of various components, and then stirred for 60 to 80 minutes based on 10 kg at a rotation speed of 20 to 30 RPM at a temperature of 40 to 50°C of purified water and mixed. Here, if the content of various components is 5% by weight or less, the efficacy may be reduced, and if the content is 10% by weight or more, the dispersibility may decrease or gelation may cause problems when impregnating the PLA nonwoven fabric. In addition, when the purified water temperature is 40°C or less, dispersibility is inferior, and when the purified water temperature is 50°C or more, various raw materials may react and gel.

On the other hand, out of 5 to 10% by weight of various ingredients, 0.05 to 0.5% by weight of xanthan gum is added, and when using a dry mask pack, it is immersed in purified water to improve adhesion and adhesion when attached to the face. Here, if xanthan gum is 0.5% by weight or more, it may be gelled, and if it is less than 0.05% by weight, adhesion may be weakened.

[Step of dipping the nonwoven fabric in purified water and then pressing it with a polishing roll]

After dipping the biodegradable PLA nonwoven fabric into the raw material mixed with various ingredients, it is pressed with two polishing rolls to force various ingredients to penetrate into the biodegradable PLA nonwoven fabric fiber.

Since the biodegradable PLA nonwoven fabric has a water absorption rate of 0.15% by weight or less, various components are not absorbed by the biodegradable PLA nonwoven fabric if it is dried without pressing after dipping, so a compression process must be performed.

[Drying through a hot air chamber]

The biodegradable PLA nonwoven fabric in which various components have penetrated is dried through a hot air chamber in which the temperature is sequentially lowered.

The temperature of chamber 1 is 95℃, the temperature of chamber 2 is 85℃, the temperature of chamber 3 is 75℃, and the temperature of chamber 4 is 65℃. When the temperature is 25g/㎡, 8m to 9m are produced for 60 seconds. Dry as much as possible.

Here, when the temperature of the hot air chamber is 95℃ or higher, the biodegradable PLA nonwoven fabric is crystallized and the adhesion to the face may decrease due to its brittle characteristic. At this time, after drying, the amount of impregnation in various components relative to the weight of the nonwoven fabric was impregnated in 15 to 20% by weight.

[Steps to cut]

Finally, the dried biodegradable PLA nonwoven fabric is cut with a press.

The biodegradable PLA non-woven fabric is finished by cutting and wrapping according to the areas used such as face packs, eye packs, nose packs, hand packs, and smile packs.

It should be noted that short PLA fibers can be manufactured and used as spunbonded nonwoven fabrics, or they can be mixed with PLA short fibers and cotton, Korean paper, and pulp.

④ As the weight change in which various ingredients are transferred to the skin layer, remove the mask pack from the face after 15 minutes, dry it so that the moisture content is less than 5% by weight, and check the weight change.

⑤ After use once, soak in 50g of purified water for 30 seconds, like No. 4, and use 2 to 3 times repeatedly.

Final weight Weight after one use Weight after 2 use Weight after 3 times of use A type 1.68g 1.51g 1.48g 1.42g B type 1.68g 1.59g 1.54g 1.51g C type 1.68g 1.62g 1.58g 1.56g

The above data are average values of 5 tests.

[result]

The above type of mask pack has excellent efficacy because various ingredients are transferred to the skin layer, and type C, which has a high moisture absorption rate, shows a result of inferior efficacy because various ingredients are absorbed into the mask pack and the amount transferred to the skin layer is small.
