It is stable at room temperature, easily soluble in water, and its aqueous solution is neutral. Urea is an important nitrogen fertilizer in agriculture, which can provide plants with the nitrogen element they need for growth and promote plant growth and development. Its fertilizer effect is long-lasting and mild, and it is suitable for all kinds of soils and crops. In industry, urea also has a wide range of uses. For example, it is used in the production of chemical products such as melamine and urea-formaldehyde resin; in the pharmaceutical industry, it can be used as an excipient for drugs; in the cosmetics industry, it can be used to adjust the humidity of products. Urea also has certain applications in the medical field, such as for detecting kidney function.<\/p>","protected":false},"featured_media":4039,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[18],"product_tag":[19],"class_list":{"0":"post-4195","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-petroleum-additives","7":"product_tag-petroleum-additives","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product\/4195","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/comments?post=4195"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/media\/4039"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/media?parent=4195"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product_brand?post=4195"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product_cat?post=4195"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/en\/wp-json\/wp\/v2\/product_tag?post=4195"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
