Description

Technical Field

[0001] The invention relates to the technical field of eye masks and discloses a highly moisturizing steam eye mask and a preparation method thereof. Background Art

[0002] Steam eye mask is a new type of eye mask used to relieve eye fatigue and improve sleep quality. Its principle is similar to that of hot compress. It uses a heating pack to heat and generate steam. Combined with medicinal ingredients such as herbal essences added to the product, it provides warmth and moisture to the eyes, relieves fatigue, and improves blood circulation in the eyes.

[0003] Traditional steam eye masks use powdered bag heating packs, which have unstable heating locations and duration, and there is a risk of powder leakage or local overheating that can damage the skin. The use of thin heating sheets can solve this problem. The heating temperature of the heating sheet can be effectively controlled, the effective time is stable, the texture is comfortable and soft, and it will not irritate the skin. It is a current research hotspot.

[0004] Among the existing products, most steam eye masks use traditional Chinese medicine ingredients that can reduce swelling and relieve pain, nourish blood and calm the nerves, clear away heat and detoxify, or use essential oils to relieve eye fatigue and soothe the body and mind. Such products can effectively relieve problems such as intraocular congestion, fatigue, dryness, and pain caused by prolonged exposure to electronic products, but they ignore the damage caused to human eyes by ultraviolet rays when working in the sun for a long time. The repair effect of such products on eye damage caused by working in the sun needs to be improved.

[0005] Therefore, it is of great significance to prepare a steam eye mask that is highly moisturizing, has good skin and eye protection effects, is rich in functions, and is comfortable to wear. Summary of the Invention

[0082] Experiment: (1) The high-moisturizing steam eye masks prepared in Examples 1 to 3 and Comparative Examples 1 to 4 were measured, and the average temperature and the maximum temperature in the heating stage were measured; the moisturizing rate was tested by referring to the in vitro gravimetric method; the specific data are shown in Table 1;

[0083] Table 1:

[0084] Average temperature / ℃ Maximum temperature / ℃ Moisturizing rate / % Example 1 40 43 66 Example 2 41 44 66 Example 3 41 44 65 Comparative Example 1 37 40 65 Comparative Example 2 41 45 57 Comparative Example 3 40 44 61 Comparative Example 4 41 48 63

[0085] Conclusion: Table 1 shows that increasing the amount of hydrogel added has little effect on the steam mask's moisturizing rate, but it does affect the heating performance of the heating element, so the amount added needs to be controlled. The use of commercially available superabsorbent resin slightly decreased the steam mask's moisturizing rate. The use of cotton fabric untreated with sericin also decreased the steam mask's moisturizing rate. There is a risk of localized overheating when using heating powder packs.

[0086] (2) 100 highly moisturizing steam eye masks prepared in Example 1 were distributed to office workers aged 20 to 45 for trial wearing; the specific evaluation is shown in Table 2;

[0088] Comfort Satisfaction with eye protection effect Example 1 97％ 98％

[0089] Conclusion: As shown in Table 2, the highly moisturizing steam eye mask prepared in Example 1 provides excellent comfort and eye protection satisfaction. This is due to the softness and good breathability of the sericin cotton layer, the excellent hydrating and eye-protecting effects of the hydrogel, and the combined effects of the traditional Chinese medicine ingredients and the essence. It can repair problems such as intraocular congestion, fatigue, dryness, and pain caused by prolonged use of electronic products. It can also relieve damage to the human eye caused by ultraviolet rays when working in the sun for a long time, moisturize the skin around the eyes, and soothe the body and mind. It is a comprehensive product.

[0090] In summary, the solution provided by the present invention can prepare a steam eye mask with high moisturizing, good comfort, and good eye and skin protection effects.
