Is surface active agent,bad material?

Surface active agent is material to help mixing of oil and water.
They exist inside our body,therefore,they aren’t bad material at all.

There are two types of surface active agent.
「Natural suface active agent」and 「synthetic surface active agent」
(human made it by using petroleum as a raw material)

Most of them are used in daily products and cosmetics. They are used to wash,create bubble,emulsify and preserve. The problem of it is they are very poisonous,high in penetration,and remaining.
The negative effects are given to body and will also damage ocea, river sice they can to break through the process of sewage.

synthetic surface active agent exists about 2,000 to 3,000 types. They are used in not only detergent, they are used in food,medicine,cosmetics also.

Difference between soap and detergent

Dish soap,laundry detergent,there exists a lot of detergents made for a house use.
Out of all products,the material listed as fat sodium,fat potassium is material we are known as a soap,natural surface active agent.

Other materials are all synthetic surface active agent. There are many types included in this catergory. From low quantity of poisnous material to material that might cause cancer,influence environmental hormone. Please be aware that there is ones that is high power of wash which might cause skin damage.

What is work of surface active agent

Detergent and facing cream,shampoo in which said as clean and drop dirtiness.
These have tendency to make bubble in good function. In food,medicine,cosmetics,they work as emulsify.

For example,dressing is mixture of oil and vinegar,before using it,it is separated into two layers and when we use,we shrink to mix them up. This is called emulsify. They mix up for once ina while. And suddenly they break into two layers. Surface active agent enables this kind of activity. Materials that normaly won’t mix to mix up for a long time. When mix yolk,the material similar to mayonnaise is made. Yolk also has a surface active agent.

Human body has characteristics of melt into water and melt into fat, surface active agent will mediate these two characteristics. Human body has 60 trilion cells and have material to work as asurface active agent. They help dissolve cholesterole in blood, waste old material inside cell by dissolving them in the blood and help activate blood movement. Surface active agent is also used in food such as ayonnaise,butter,margalin and milk beside cosmetics.

Surface active agent has great ability and it is not bad material,however we must carefully check it and see what they are made from. Materials inside human body,or the materials which is closer to human body is good for human.

Most of synthetic surface active agent have high ability and is capable to do high perfomance for a long time when compare to natural ones. Natural ones are prefered with safety,but often oxidized and perfomance is lower. Please put in your mind these merit and demerit.

Danger of synthesis surface active agent

This substance has characteristics of mix materials in which usually separated. They often put two layers together. Human skin will protect harmful materials at skin fat layer,however synthesis surface active agent will surpass fat layer and enter human body and might enter blood stream,expand into human body.

For example

detergent left over on the dish after washing will enter human body
detergent left over on the clothes will melt in water molecule in air or swet and enter human body
deodorant spray will enter human body through mouth and nose

They also

damage protein
when enter body,even liver can’t break them
Said to break liver cells and might be cause of disease in liver
When wash face and hand,they left over on the skin
When disposed to river,ocean, might pollute environment
