Product description:
The tobacco moisture-retentive agent we produce is made from the extraction of natural plants and it is proved to be safe and effective. Our product can increase the resiliency in the tobacco leaf, minimize the damage during the production, and decrease the unit consumption of the tobacco leaf. Our tobacco moisture-retentive agent is also able to replace propylene glycol, glycerin and other chemical moisture-retentive agents so that the possible harm to human bodies can be avoided. In addition, the tobacco moisture-retentive agent can improve the quality of cigarettes and lower the tar contents to curtain extend.

Our moisture-retentive agent has been proved to be in line with the industrial standards and improve the quality of cigarettes by Zhengzhou Tobacco Research Institute of China Cigarettes Corporation.

How to use:
Our product can be used separately or in combination with other moisture- retentive agents. It is easy to use. Just put it directly into the water tank and it mixes very well with other substances.

The application of xylitol moisture-retentive agent in the tobacco industry:
Tobacco moisture-retentive agent is a chemical compound which can keep the moisture effectively. The most commonly used tobacco moisture-retentive agents are polyols compound including propylene glycol, glycerin, diglycerol, and sorbitol etc. Propylene glycol has the most uses but it is expensive. Glycerin and diglycerol etc. are chemical compounds and their output is not big. Moisture-retentive agents made from xylitol liquid not only have the similar physical and chemical properties as propylene glycol but also they are inexpensive and easy to acquire. Xylitol can be made from agriculture waste materials such as corn cobs and sugarcanes bagasses with hydrolysis plus hydrogen. There are always sufficient raw materials around, the quality is steady and the cost is low.

Experiments show that add 1% xylitol and 1% propylene glycol respectively to the cut tobacco with the same formula, then put them in a condition with constant temperature and humidity for a simultaneous experiment. Measure the water-losing condition of the cut tobacco every 24 hours and the results are as follows.

time relative humidity	Day 1	Day 2	Day 3	Day 4
76%	0.04	0.118	0.308	0.520
80%	3.80	7.64	25.2	32.7
92%	21.7	37.7	92.3	125.6
