what will happen after eating the soap?

In chemistry, soap is a salt of a fatty acid. Soaps are mainly used as surfactant for washing, bathing, and cleaning, but they are also used in textile spinning and are important components of lubricants. Soaps for cleansing are obtained by treating vegetable or animal oils and fats with a strongly alkaline solution. Fats and oils are composed of triglycerides: three molecules of fatty acids attached to a single molecule of glycerol.The alkaline solution, often called lye, brings about a chemical reactio known as saponification. In saponification, the fats are first hydrolyzed into free fatty acids, which then combine with the alkali to form crude soap. Glycerol, often called glycerine, is liberated and is either left in or washed out and recovered as a useful by-product according to the process employed.
Soaps are key components of most lubricating greases, which are usually emulsions of calcium soap or lithium soaps and mineral oil. These calcium- and lithium-based grease are widely used. Many other metallic soaps are also useful, including those of aluminium, sodium, and mixtures of them. Such soaps are also used as thickeners to increase the viscosity of oils. In ancient times, lubricating greases were made by the addition of lime to olive oil.

Tempestt Henderson, a 19-year-old girl from Florida, has a rather peculiar addiction – she can’t help eating soap bars and washing powder. There are worst things to be addicted to, but this has to be one of the strangest.
The young girl remembers she loved the smell of washing powder on her mother’s cardigan and on her bed sheets, and so do many other people, but that doesn’t make them want to stuff their face with the toxic substance. But that’s exactly what Tempestt felt when she first dipped her fingers in washing powder and licked it off. ‘I dabbed the powder onto my tongue and it tasted so sweet, and salty…it just felt so right. I was hooked straight away.’ says the young nursing student.
She new that stuff was hazardous to her health, but she loved it so much she couldn’t stay away from it. From the moment she woke up, she would give in to her washing powder craving, ignoring the warning labels. Before she knew it, Tempestt began licking off the soap bubbles of her skin in the shower, and popping tiny chunks of soap in her mouth and suck on them. Eating soap felt much cleaner than just washing with it, and the young girl claims that at one point she would go through five bars of soap in a week.(By Jeff Maysh UPDATED:22:33 GMT, 8 February 2011)

Fortunately, in your case soap is not a very dangerous substance, though in large amounts over time it could disrupt your health. Soap is generally non-toxic and should not lead to poisoning. However, it can cause diarrhea, vomiting or skin irritation. If eaten in great amounts, soap and dish detergent can kill. Most soaps and detergents contain toxic chemicals like potassium carbonate and sodium carbonate. Symptoms that might result from eating soaps and detergents include severe pain in the throat, loss of vision, low blood pressure develops rapidly, and severe change in blood acid levels, which can lead to organ damage. Symptoms

• Eyes, ears, nose, and throat
  • Severe pain in the throat
  • Severe pain or burning in the nose, eyes, ears, lips, or tongue
  • Loss of vision
  • Throat swelling (which may also cause breathing difficulty)
• Heart and blood circulation
  • Low blood pressure -- develops rapidly
  • Collapse
  • Severe change in blood acid levels, which can lead to organ damage
• Lungs
  • Breathing difficulty (from inhalation)
• Skin
  • Irritation
  • Burns
  • Necrosis (tissue death) in the skin or underlying tissues
• Stomach and intestines
  • Severe abdominal pain
  • Vomiting, may be bloody
  • Burns of the esophagus (food pipe)
  • Blood in the stool

The doctor gave Tempestt intensive Cognitive-behavioral therapy, or CBT, to give her replacement thoughts that will prevent her from compulsively reaching for soap.
'I’m learning to think about positive things when I feel I need to eat soap,' she said.
She has also been encouraged to go for long walks, avoiding places where soap is present, like bathrooms and laundrettes.
She added: 'Doctors have encouraged me to talk about my issues, because they think my addiction is caused by me bottling things up.'
And for the teenager who used to take not one, not two, but three bottles of soap into the shower, she hasn’t eaten soap since September 2010.
When her mother found out about her daughter’s addiction, she ordered Tempestt to return home from college. It may have been a smart move as Tempette admitted: 'I just couldn’t face being back there, alone, with a campus full of soap.'
Today, she faces a long road of recovery, but says she hopes she’ll never have to eat soap ever again.
