FMEE has no promotional or practical value

Question 1: The labeled content of FMEE is 70%, but the actual dry content is only 65%; when adjusted to a 99% content level, the price exceeds 20 yuan per kilogram. Question 2: FMEE claims to have good low-temperature fluidity, but in reality, any surfactant such as AEO-9 combined with 35% water – resulting in a concentration of 65% – also exhibits good fluidity. Question 3: The emulsification performance of FMEE – the claim that its oil and wax removal capacity is several times that of AEOs – is completely unfounded. When using mineral oil No. 7 as the substance to be emulsified, FMEE’s emulsification ability is clearly inferior to that of the AEO series, and even worse than that of the isohydroxy ether series. Question 4: FMEE is not a low-foam product; it produces a high amount of foam, and defoaming occurs after mixing, indicating the presence of defoaming agents. Question 5: At room temperature or moderate temperatures, that is, when the temperature is below 80 degrees, FMEE has very poor degreasing and dewaxing capabilities. Therefore, its performance is poor in household cleaning, hotel linen cleaning, and metal surface cleaning. Question 6: FMEE has a high cloud point, allowing it to be used at high temperatures; however, FMEE contains anionic components, and it is clear that the cloud point is increased by the addition of these anionic components. Question 7: When converted to a 99% purity level, FMEE costs over 20 yuan per kilogram, and even exceeds the cost of isomerized tridecyl fatty alcohol polyethers; clearly, its cost-effectiveness is very poor, and using FMEE only increases costs. Many of FMEE’s performance characteristics do not match what is advertised; its emulsifying, degreasing, and cleaning capabilities fall short of the claims made. FMEE’s performance is significantly inferior to that of the AEO series, as well as to that of heteroalcohol ethers. In terms of price, FMEE is even more expensive than heterotridecyl alcohol polyethers, resulting in a poor cost-performance ratio. Using FMEE in large quantities does not reduce costs for users; instead, it increases production costs. FMEE has no promotional value or practical utility.
