Description

[0001] 1. Invention Title A water-soluble transfer film and its application method Technical Field

[0002] This patent belongs to the field of functional skin care and cosmetic products, and specifically designs a method for manufacturing and using a water-soluble and transferable film. Background Technology

[0003] Currently, most cosmetic stickers or water transfer films on the market rely on adhesive for fixation, or require users to press firmly to transfer the design to the skin. Furthermore, traditional water transfer tattoo stickers are often only suitable for simple designs, and their inks mostly lack cosmetic-grade film-forming agents, failing to achieve waterproof and smudge-proof effects. They are also unsuitable for use on curved skin surfaces and cannot meet the demands of transferring sophisticated makeup or active pharmaceutical ingredients. Therefore, the market urgently needs a multi-purpose transfer film that can conform to curved skin, requires no adhesive backing, eliminates the need for forceful pressing, and is waterproof and smudge-proof. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a manufacturing process and usage method for a multi-purpose transfer film that can conform to curved skin, requires no adhesive backing, does not require forceful pressing, and is waterproof and smudge-proof, so as to solve the technical problems of existing transfer films that rely on adhesive backing and require forceful pressing, such as pattern misalignment and skin pulling. Technical solution

[0005] To achieve the above objectives, the present invention provides the following technical solution: A sacrificial, adhesive-free, water-soluble support layer; and a functional layer attached to the surface of the support layer.

[0006] The functional layer contains transfer film functional components and film-forming agents.

[0007] When using, apply the transfer film to the skin and apply water. The support layer of the water-soluble transfer film will soften and dissolve, eliminating the need for vigorous pressing to promote transfer. The transfer film fixes the functional ingredients to the human body surface, forming a waterproof and abrasion-resistant functional fixation layer. Beneficial effects

[0008] 1. No adhesive backing, no residue: Avoids physical strain on the skin when peeling off the adhesive backing. The support layer completely dissolves when exposed to water, leaving no foreign body sensation and providing a comfortable and natural feel.

[0009] 2. Excellent fit: The support layer is soft and elastic, and can perfectly fit the curves of the skin even before and after softening in water.

[0010] 3. No need for heavy pressing: This invention eliminates the heavy pressing operation of traditional transfer printing, avoiding problems such as pattern misalignment and stretching deformation caused by heavy pressing.

[0011] 4. Wide range of applications: The functional layer can carry cosmetic pigments, skin care active ingredients or pharmaceutical active ingredients, and has a wide range of uses.

[0012] 5. Long-lasting effect: The film-forming agent can form a waterproof and rub-resistant protective layer, prolonging the retention time of functional ingredients on the skin. Attached Figure Description

[0014] Figure 1 This is a cross-sectional schematic diagram of the transfer film of the present invention.

[0015] Figure 2 This is a schematic diagram of the steps for using the film of the present invention. In the diagram, numbers ① to ④ are respectively: ① applying the film to the skin, ② moistening the film with water, ③ gently smoothing along the surface of the film, and ④ removing residual film debris while retaining the functional ingredients on the skin surface. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0017] This embodiment provides a water-soluble transfer film. The described water-soluble support layer is a 0.05 mm thick polyvinyl alcohol film, and the described functional layer is an acrylic cosmetic film-forming agent and a water transfer ink for pigments, applied to the film surface and then dried.

[0018] The method of use is as follows: Apply the film to the clean and dry skin surface, moisten with a little water and wait. After the support layer softens, smooth it along the surface of the film to make it adhere to the skin surface. After the support layer is completely dissolved, remove the remaining film. The functional ingredients are fixed to the skin surface by the film-forming agent, forming a waterproof and anti-scratch functional bonding layer.

[0019] It should be noted that the smoothing process here is for physical adhesion to curved surfaces, rather than for increasing pressure to promote transfer. The transfer in this invention mainly relies on the adhesion between the film-forming medium contained in the functional layer and the surface, and does not forcibly rely on physical pressing.

[0020] Furthermore, the materials used in this embodiment are merely examples. The support layer described in this invention includes, but is not limited to, polyvinyl alcohol. Other water-soluble polymeric materials that are soluble in water can also be used as substitutes, such as hydroxypropyl methylcellulose, pullulan, gelatin, starch, sodium carboxymethyl cellulose, or water-soluble polyester. These equivalent substitutions are all within the scope of protection of this invention.

Claims

1. A water-soluble transfer film, characterized in that, include: Sacrificial, adhesive-free, water-soluble support layer; A functional layer is attached to the surface of the support layer.
