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 food processing technology, specifically relating to an oat bran β-glucan extract, its preparation method, and its application. The preparation method involves obtaining the oat bran β-glucan extract from oat bran through multi-stage enzymatic hydrolysis. The enzymes used in the multi-stage hydrolysis sequentially include pentosanase, thermostable α-amylase, and proteinase K. This invention, under ultrasound assistance, allows pentosanase to efficiently break down cell walls first, significantly increasing the release rate of β-glucan. Subsequently, thermostable α-amylase and proteinase K precisely remove starch and protein impurities sequentially, greatly improving the purity of the product. This process route is mild, highly specific, and operates continuously, reducing impurity residue while improving extraction efficiency, providing a reliable and cost-effective solution for the large-scale preparation of high-purity, highly bioactive oat β-glucan.

This invention belongs to the field of cosmetic technology, specifically relating to a composition with water-locking and brightening functions and its targeted microcarrier delivery system. The water-locking and brightening composition provided by this invention mainly consists of niacinamide, tranexamic acid, oat β-glucan, disodium EDTA, and sodium hyaluronate. This composition can achieve a synergistic effect of water locking and brightening, effectively improving dullness, dryness, and uneven skin tone. Simultaneously, this invention also provides a targeted microcarrier delivery system, which is prepared by encapsulating the above composition in an internal aqueous phase using liposome technology, and simultaneously covalently attaching a targeting ligand to the surface of the liposomes. The targeted microcarrier delivery system obtained by this invention can actively target melanocytes and keratinocytes, achieving precise delivery of brightening and water-locking ingredients, significantly improving skin tone and addressing the root causes of dullness and uneven skin tone.

The application provides a preparation method and application and composition of oat beta-glucan, and relates to the technical field of cosmetics.The preparation method comprises the following steps: (1) oat is crushed, mixed with alkaline water, and subjected to subcritical water extraction at 150-180 DEG C to obtain a crude extract; (2) the pH of the crude extract is adjusted to be acidic, the crude extract is allowed to stand, and the supernatant is taken; (3) the pH of the supernatant is adjusted to be neutral, then amylase and neutral protease are added to perform enzymatic reaction, and the filtrate is obtained through filtration; and (4) the filtrate is purified through Sephacryl S-200 gel resin, concentrated, and oat beta-glucan is obtained.The method significantly improves the yield of oat beta-glucan, maximally retains the anti-aging activity of oat beta-glucan, and has better anti-aging, anti-wrinkle and skin elasticity improvement effects; oat beta-glucan and other anti-aging ingredients are mutually matched, and the effect of significantly removing DPPH free radicals is brought.
