Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether, made by natural high polymer cellulose as raw material and series of chemical processing. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.
It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.

- Q: Is it safe to use and store gas with ethanol in lawnmowers, tillers and trimmers with additive added?
- Most gas engined tools recommend that they be stored for extended periods of time with no gas in the tank or in the carburetor. They suggest we pour out the gas into a safe container, then run the device until it is out of gas. Most also suggest removing the plug and putting a small amount of motor oil in the cylinder, then rolling the engine over with the pull cord before putting the plug back in. These are good suggestions but, in the Pacific Northwest, I have been known to cut my grass at least once in every month of the year. Sometimes I skip a month or two but I usually have to cut the stuff so it doesn't get my socks wet when I walk across it. My mower rarely goes long enough to have problems with gas. I do, however, fill the tank to the top and put the lid on it. With less air, there is less space for evaporation. Gas here always has up to 10 % ethanol in it. Where you live, you may want to get some gasoline stabilizer additive for your gas can. You mix it according to their instructions then fill the mower tank. It stabilizes the chemical makeup of the gas to prevent problems with the engine. If you use that stuff, you shouldn't have any problems next spring.
- Q: I know fuel additives like STP‘s Octane booster (don‘t complain about them I know they aren‘t all that), I know they can seriously f*ck up more modern engines. But I have a 1987 BMW. with an inline 6 engine. I am wondering if the Injector cleaner, octane boosters, etc fuel additives will damage anything.
- These things are a waste of money. Octane boosters are not the same and are real. Gasoline already has additives and ethanol is known to cause problems in boat induction systems. My fear is that if you do have any varnish in your older tank that the additive might knock it off and plug the fuel filter which should have stopped anything larger than few microns from getting to your injector anyway. Fuel system cleaning at most service centers are largely an income generator with no real benefit unless they are actually cleaning the intake. Most of these shops disconnect a vacuum hose and put cleaner through it. As this path is not through the injector anyway it is of little value.
- Q: foods?
- I'm not sure how safe it is,but I also know there are some things in soda that is also used as a component in agricultural fertilizers.I rather make things at home,intead of getting processed foods.I know what goes into them,and how they are prepared.Processed foods are nothing but additives,artificial flavorings,and artificial sweeteners.You really don't know what you are eating when you eat processed foods.So many people don't really think about that,just the taste.
- Q: Idk if this a crazy thought. But do some food companies add chemicals that work on ur brain to make you want more? For instance, potatoe chips, one company says on the package you cant eat more than one or something like that. So can they add something to make you want more of them?
- No. I don't think they do. It would be illegal. And since companies have to list all their ingredients, imagine the issues this would have if they were ever found out. That said, McDonalds use to soak their potatoes in sugar before deep fat frying them, which is why everyone loved their friesuntil consumers found out about it!! EDIT - My point about the McDonald's fries was NOT that everyone doesn't still love them. The point was, when consumers found out about it, McDonald's quit doing it because consumers thought it was 'unhealthy'.cuz other than that added sugar, McDonald's fries are so healthy, as we all know. PS - Salt and sugar are NOT additives.
- Q: is there any transmission fluid additives at the auto parts store that actually work for a slipping transmission?
- I think Iron Maiden is better. hallowed be thy name 3
- Q: What is the addtivtive inverse of 9x -y+5y-4-6x-6yHow do you find them?Thanks in Advance
- -9x thats all i no
- Q: can you put an additive in a premium only car when there is no premium available?
- you had a transmission problem the fluid change is just that a change it does not fix a problem which is what you had go to transmission shop get it looked at
- Q: fuelsome bottles say to use every 3000 miles, but then under it, it will say good to use after every fill up. Which one is it, for fuel injector cleaner?oilcan i use Marvel Mystery oil in between oil changes to top off a bit? Is this ok, or do I have to drain in soon like seafoam. Also if I overfill the oil, what will happen?thanks
- It means use the injector cleaner every 3000 miles but after you have filled your tank, Using oil additives in used oil is a waste of time. Most if not all manufacturers frown on the use of additives and their use will invalidate the warranty. Personally I think that they're a complete waste of time and money (42 years experience)
- Q: Can the food additive be used?
- Is this additive? Never heard of eh.
- Q: what is industrial additives?
- Additives are used in Agriculture to change to context or chemical status of a product. Example in silage you add additives to reduce the PH levels to help preserve it for longer. or even adding urea to straw to make it more palatable
