| Physical and Chemical Properties | Humic acid sodium, also known as the rich new sodium, humic acid sodium, is the sodium salt of humic acid, black brown or gray black shiny granules or powder, odorless; Soluble in water. Generally, sodium humate is prepared by the action of peat powder and caustic soda solution. In agriculture, sodium humate can be used as fertilizer and plant growth stimulating hormone. It can stimulate the growth and development of crops, improve soil structure and improve the drought resistance of crops. Promote the activation of nitrogen-fixing bacteria. In the industry, sodium humate can be used to increase the capacity of yeast and increase the yield of ethanol. It can also be used as a lubricant and the like. The above information was compiled by Tong Tong. |

Humic acid, sodium salt - Reference Information
| LogP | -2.08 at 20℃ |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Properties and applications | sodium humate is a natural polymer compound, mainly black humic acid, there are also a small amount of brown humic acid and yellow humic acid, humic acid sodium is a colloidal substance, has a strong adsorption and chelating effect, can absorb a large number of vaginal secretions, keep the vaginal wall clean, and has a certain anti-inflammatory effect. For the decrease of estrogen levels, vaginal inflammation caused by the local resistance to decline, can make it subside. The anti-inflammatory effect results from inhibition of hyaluronic acid activity and activation of pituitary-adrenal cortex function. There is also a certain role in the precipitation of protein. Clinically external for convergence, hemostasis, pain, itching, anti-exudation, anti-inflammatory, swelling and so on. Commonly used in the treatment of cervical erosion, I °, II ° better; III ° also can alleviate and is expected to cure. in the treatment of cervical erosion and senile vaginitis, the patients were smeared evenly with cotton ball dipped in 20% sodium humate paste, and placed in the affected area, and then removed after 12~24H, once every 2 days; 10 times for a course of treatment. No sexual intercourse and bath during treatment. For other inflammation and trauma, the product can be soaked and wet by 1% aqueous solution. |
| purpose | used as fertilizer, plant growth hormone, feed additive, lubricant, drilling additives |
