Abstract

The invention discloses a moisturizing eye mask prepared from bacterial cellulose. The method for preparing a moisturizing eye mask from bacterial cellulose comprises: inoculating 1-2 rings of activated inclined seed Gluconacetobacter xylinum into a medium, and conducting oscillating culture to obtain a seed solution; then inoculating the seed solution into the medium, fully oscillating the bacterial solution obtained by mixing the seed solution and the medium to make them mixed uniformly, then conducting stationary culture, thus generating a bacterial cellulose membrane floating on the solution surface, flushing the generated bacterial cellulose membrane with water to remove the medium and impurities on the membrane surface, then immersing the membrane in an alkali solution to remove thalli and residual medium from the membrane, and finally flushing the membrane with distilled water till the pH value of the membrane is measured up to 7-7.2, thus obtaining a bacterial cellulose wet membrane, which is then cut into an eye mask. The eye mask has the advantages of good moisturizing property and biological tissue compatibility, no toxicity, harmlessness, and simple material processing technology.

Description

technical field [0001] The invention relates to a novel eye mask, in particular to a moisturizing eye mask prepared from bacterial cellulose. Background technique [0002] The physiological characteristics of the skin around the eyes are different from those of the face. One is that the thickness of the skin around the eyes is only a quarter of the average thickness of the body skin, which is delicate and fragile; the other is that the skin has fewer elastic fibers and is prone to skin relaxation; Rich circulation, thin capillary walls, easy to bruise and edema. In addition, there are no sebaceous glands around the eyes, and the amount of subcutaneous fat is also very small. The activity of facial expression muscles pulls the skin around the eyes, making it prone to wrinkles and aging. Therefore, the skin around the eyes needs special moisturizing care. [0003] There are many skin care products for eye skin. Ordinary skin care products may not be suitable for the skin ar...
