This invention provides a composition for soothing dry, itchy, and red skin in infants and children, and its application. The composition comprises 1-8% plant oil, 5-12% moisturizer, and 0.1-0.5% soothing ingredients. The plant oil contains ≥1% shea butter. Through the synergistic effect of the compound plant oil, moisturizer, and soothing ingredients, and with oat β-glucan modified by acetylation, the permeability and skin affinity are improved. The preparation employs a segmented emulsification and homogenization process, controlling the oil droplet size to 0.2-0.4 μm, and low-temperature compounding preserves the active ingredients. This composition achieves multiple benefits, including rapid soothing of dryness, itching, and redness, repair of the skin barrier structure, and balance of the skin microecology. Experimental verification shows that this composition has a significant inhibitory effect on inflammatory factors, is gentle and non-irritating, and can provide comprehensive protection for the delicate skin of infants and children.

This invention belongs to the field of contact lens technology, and provides a moisturizing protein-based contact lens and its preparation method. The preparation method includes the following steps: mixing a silk fibroin solution and a hyaluronic acid-binding protein solution to obtain a protein mixture solution; mixing a hydrophilic modification component, an oxygen-permeable modification component, and water to obtain a composite modifier; mixing the protein mixture solution, the composite modifier, and a crosslinking agent to obtain a pre-crosslinked mixture; molding the pre-crosslinked mixture and performing gradient crosslinking, followed by sequential soaking in buffer solution, rinsing, and sterilization to obtain the moisturizing protein-based contact lens. The contact lens of this invention uses protein as the main component, does not rely on silicon-based substances or harmful crosslinking agents, and possesses high biocompatibility, high oxygen permeability, suitable mechanical properties, and controllable degradation.

The invention relates to the technical field of eye protection liquid, and particularly discloses vision prevention and control eye protection liquid and a preparation method thereof.The vision prevention and control eye protection liquid is prepared from deionized water, propylene glycol, sodium hyaluronate, protection extract, antibacterial and anti-inflammatory ionic liquid, vitamin B6, taurine, witch hazel distillate, dipotassium glycyrrhizinate, borneol, menthol, E1004 and moisturizing polysaccharide; all the components in the eyesight prevention and control eye protection liquid take effect synergistically, the eyesight prevention and control eye protection liquid can moisten eyes for a long time and reduce tear evaporation while effectively resisting inflammation and relieving, eyestrain is relieved by adjusting ciliary muscle metabolism, and occurrence and development of myopia are prevented in an auxiliary mode through the retina protection effect.

The invention relates to the field of disposable hygienic products, and provides a production method of a leakproof adult paper diaper which comprises a paper diaper body, and the paper diaper body comprises a liquid-permeable top layer, an absorption core layer and a liquid-tight bottom layer which are arranged from top to bottom. The paper diaper comprises a paper diaper body, the paper diaper body is provided with a front end portion located at the front end and a rear end portion located at the rear end, the rear end portion of the paper diaper body is provided with a first leakage-proof piece, the first leakage-proof piece is provided with a first leakage-proof opening with an inward opening, and the first leakage-proof piece can stretch out and draw back in the width direction. According to the leakproof adult paper diaper, the first leakproof piece is arranged at the rear end, the problem that rear leakage is prone to occurring when a woman wears the leakproof adult paper diaper is effectively solved, the first leakproof piece can be telescopically buffered according to the urine amount, the leakproof reliability is further improved, and the technical problem that the leakproof adult paper diaper is poor in rear leakage prevention effect is solved.
