The humectant prevents the toothpaste from solidifying and hardening in the tube , and make the paste have gloss and other effects. Humectants in toothpaste include glycerin, sorbitol, etc.
The dosage is 15% to 30%. The dosage in transparent toothpaste exceeds 30%. Its function is that when the toothpaste is exposed to considerable humidity changes, it can stabilize the moisture in the toothpaste, maintain the plasticity of the toothpaste and make it soft and lubricated, and it will form a good paste strip when extruded. It prevents the toothpaste from freezing and hardening in cold weather, prevents the toothpaste at the mouth of the tube from drying out and agglomerating in a dry environment, prevents the paste from drying out and hardening (especially the hardening at the mouth of the tube that is difficult to squeeze out), and makes the paste glossy Equivalent performance.
Below, Bethesda will give you a brief introduction to glycerin as a humectant in toothpaste:
Glycerin (also known as glycerin) is colorless and An organic substance with a smelly, sweet taste and a clear, viscous liquid appearance. It is miscible with water, alcohols, amines and phenols in any proportion, and the aqueous solution is neutral. Glycerin is a polyol moisturizer. The hydroxyl groups in the molecular structure can form hydrogen bonds with water molecules, which plays a good role in absorbing and locking water. Glycerin has a wide range of uses. Currently, it has more than 1,700 uses. It is used in both food and industry.
The industrial production methods of glycerin can be divided into two categories: the method using natural oils as raw materials, and the resulting glycerin is commonly known as natural glycerin; the synthetic method using propylene as raw material, and the resulting glycerol is commonly known as synthetic glycerol.
Food-grade glycerin is a sweetener and humectant commonly used in the food processing industry, and is mostly found in sports foods and milk replacers. Food-grade glycerin can be used as food additives. It is qualified in terms of purity, color, and heavy metal content, and comes with an inspection and quarantine health certificate for the corresponding batch. Food-grade glycerol must be certified by the China Food Hygiene Inspection Bureau and be deemed to comply with the “Food Safety Standard Food Additive Consumption Standard” (GB2760 standard).
