'Hard' soap vs. 'Soft' soap: Why do they work this way?
网页In school, we did an experiment using fat and $\ce{KOH}$ to create 'soft' soap. Afterwards, we added $\ce{NaOH}$ to change it into 'hard' soap.

everyday chemistry - Will alcohol or soap damage plastic or …
网页2012年9月6日 · Alcohol will damage some plastics, but not all. I will list my answers by the resin code, or "recycling symbol", found on most plastic items: Poly (ethylene terephthalate), PET or PETE - PET is not very soluble in ethanol or isopropanol, but prolonged exposure may cause crazing or stiffening due to the dissolution of plasticizers.
Why hot water is more effective than cold water in cleaning
网页2016年10月26日 · The hydrogen and oxygen molecules in water form hydrogen bonds, which form a type of skin on the surface of the water. This skin is strong enough to support the weight of very light objects.

Soap versus Shampoo - Chemistry Stack Exchange
网页2014年11月18日 · Shampoo, or more specifically the detergents present in it, are similar, but produced by a different process, to create a surfactant that is less likely to bond to the mineral compounds in hard water, and so is more effective than soap when using it with tap water from most regions.

Reaction of soap with water - Chemistry Stack Exchange
网页2014年11月18日 · 1. The soap dissolves in the water. Dissolution is not a chemical change because the same chemicals are present, they just interact with each other differently. Like CHM said, soaps act as surfactants and the difference in surface tension improves the survivability of bubbles, thus creating a "foam". Share.
