Eye patches are typically made from skin-friendly materials like hydrogel, cloth, or bio-cellulose, designed to deliver targeted skincare benefits to the delicate under-eye area.
The manufacturing process varies depending on the material used:
-
Hydrogel Patches: These patches are created by solidifying a gel-like substance composed of water, polymers (like carrageenan or konjac), and active ingredients (such as hyaluronic acid or collagen). The mixture is then molded into the desired shape and allowed to set. Hydrogel eye patches offer excellent hydration and adherence to the skin.
-
Cloth Patches: These patches consist of a thin layer of fabric, often cotton or rayon, that is saturated with a serum containing active ingredients. The cloth is cut into the shape of an eye patch and then soaked in the solution until fully saturated.
-
Bio-Cellulose Patches: Bio-cellulose is a natural fiber derived from fermented coconut water. During the manufacturing process, microorganisms cultivate the cellulose, which forms a sheet-like material. This material is then cut into the eye patch shape and infused with a serum rich in beneficial ingredients. Bio-cellulose patches are known for their exceptional adherence and ability to deliver ingredients effectively.
General Steps in Eye Patch Manufacturing:
- Formulation: The active ingredients (e.g., peptides, antioxidants, vitamins) are carefully selected and combined with a base material appropriate for the chosen patch type (hydrogel, cloth, or bio-cellulose).
- Mixing and Preparation: The ingredients are thoroughly mixed to ensure a uniform distribution. For hydrogel patches, this step involves heating and cooling the mixture to facilitate gel formation.
- Shaping and Molding: The material is then shaped into the desired eye patch form, either by pouring into molds (for hydrogel) or cutting from a sheet (for cloth and bio-cellulose).
- Serum Infusion: The patches are soaked or saturated with a serum containing additional active ingredients and hydrating agents.
- Packaging: The finished eye patches are individually packaged or placed in multi-packs to maintain their freshness and efficacy. Preservatives are typically added to prevent microbial growth.
- Quality Control: Rigorous quality control checks are performed throughout the manufacturing process to ensure the safety and effectiveness of the eye patches.
In summary, eye patches are made by combining various materials like hydrogel, cloth, or bio-cellulose with targeted skincare ingredients through processes like molding, saturation, and careful packaging. The choice of material impacts the patch’s texture, adherence, and delivery of beneficial ingredients to the skin.
