Another interesting additive in many plastics is glass fibres or beads, they are often used to strengthen the plastic and give it slightly different mechanical properties. The downside of the glass fillers is that they erode the tools much more quickly (glass is very abrasive), kind of the opposite of Tallow which helps to keep the plastic flowing over the surfaces better.

Do you have an example?

your car's pedals if they're made of a polymer, are probably made of glass filled nylon

Perhaps the main thing about tallow is that there's a glut of it, likewise lard. People want more and more meat, but want it to be leaner, creating a surplus of tallow. Also, its use in deep fryers, e.g., by the fast food industry, was curtailed when vegetable oil became preferable in the market. A relative of mine worked in a chemical factory in Detroit, that made lubricants for metal working. Many of them were eith…

I was curious, and found the ingredients for a 1992 bar of zest from an eBay photo. It was a mix of soap with the detergent sodium cocoglyceryl ether sulfonate. The current recipe is all soap but they added a couple of chelating agents: Pentasodium Pentetate, and Tetrasodium Etidronate. The problem with the new recipe is these chelating agents suck. The only thing that can jail Mg/Ca2+ faster than soap scum forms is…

What is STP?

This piece avoids mentioning why it was written- around this time, it came to light that new UK bank notes contain beef tallow so are problematic for Hindu and vegan people who rightly have problems with these replacing old paper notes.

"This process of using fatty acids derived from animal fats has become headline news as different groups have protested against the use of animal products in the production of the new £5 note."

The phrase "There are alternative options such as non-animal fats and hydrocarbon waxes, but these might increase the cost of production, reduce efficiency, affect recyclability and finally negatively affect the environment.".... ....is such a semi-randomly grab-bagged set of statements similar to a set of nigh-unverifiable closing statements made as a desperate last-ditch attempt at proving a point in a debate that…

Anything from a corporation saying “fearful” (for your wallet) things like “may cost more to produce(costing you more)” or reduce efficiency (costing you more) etc… Is just reworded excuses as to the corporation’s choosing profit. For they will never say “profit us less.”

Corporations can choose:

1. making a profit

2. going out of business

If you raise the cost of doing business for a corporation, the cost of their products and services is going to rise accordingly.

Sodium triphosphate. It surrounds the Mg/Ca ions so they can’t transform the soap to soap scum which makes glasses cloudy and wastes soap.

Stearic acids are used everywhere, including detergents, shampoos, soaps, etc. TIL they're made from tallow.

Not all. Some is from plants, like palm or shea.

Yeah I always assumed Palmolive was made of palm oil.

Though with all the misleading advertising these days who knows.. I don't know chemistry well enough to determine this.

Which is why it's only used in certain parts that would benefit from having glass filling, like tools for instance. You also pay for it anyways; I would be surprised if any of the consumer grade Ryobis from Home Depot had glass fiber reinforced polymer cases, while a Hilti almost surely does if not metallic.

thank you. I'm glad it isn't the STP you add to your oil-burning engine.

P.S. Do you mean sodium tripolyphosphate?
