what the heck is in a johnson's baby shampoo?

Breaking down the ingredients in a johnson's baby shampoo:

Water - (H2O)
we all know water ... hopefully it is clean water.

Cocamidopropyl Betaine -
(CAPB) is a synthetic surfactant (wetting agents that lower the surface tension of a liquid so it can spread out easily) derivative of coconut oil (i know what that is) and dimethylaminopropylamine (now that is a mouthful try saying it 10 times really really fast, but i still don't know what that is?) it is some kind of amino compound ... but it has some impurities that can lead to skin irritation, but not likely allergy if not produced correctly.
And one property being an antiseptic. Also help stabilize the foam in the shampoo.

PEG-80 Sorbitan Laurate -
(also known as PEGs Sorbitan and sorbitol Fatty Acid Esters) is detergent like chemical that works as a surfactant ... ... according to the cosmetic ingredient review expert panel ... it is safe to use.cleans skin and hair by helping water to mix with oil and dirt so that they can be washed away. okay that make sense just as long as it is safe ... but note that this is synthetic.

Sodium Trideceth Sulfate -
is in the family of organic salts. it is is also a surfactant (so how many surfactants do we need in a baby shampoo?) less irritant and milder than sodium lauryl sulfate found in most adults shampoo products is a plus. a cleansing agent that has conditioning properties.

PEG-150 Distearate -
basically the same thing like all of the above that helps with cleaning skin and hair by helping water to mix with oil and dirt so it can be easily wash away ... etc
it is produced from stearic acid which is a natural occurring fatty acid derived from animal fats and oils. stearic acid mixed with number of units of ethylene oxide to create the desired chain.
and what the heck is ethylene oxide? it is an organic compound that use to sterilize the majority of medical supplies such as bandages and surgical implements. in itself this is classified as carcinogenic to humans by the international agency for research on cancer.
so then my next question is if it is mixed with stearic acid then it is no longer carcinogenic?

Fragrance - smells good, but do not know what kind or if it is safe

Polyquaternium-10 - (quaternized hydroxyethylcellulose)
also known as quaternium-19 is a white granular powder with characteristic amine (organic compounds derivatives of ammonia) odor and deemed safe by the cosmetic ingredient review expert panel. it can reduce static electricity and enhances appearance and feel of hair by increasing hair body, sheen and texture of hair that has been damaged. it absorbed well into hair.

Tetrasodium EDTA - and the EDTA = ethylenediamine tetraacetic acid
wow ... okay no wonder they need the shorter version ... nor do i know what it is ... okay it is a chelating agent? something to do with separating bonds of atoms ... yada yada ... trying to make some sense of this ... oh okay it is a water softener ... basically getting rid of the metals in water by stripping it away!

okay ... still not finished yet

Quaternium-15 - is a quaternary ammonium salt or compound used as a preservative in many cosmetics and industrial substances. They are used as disinfectants, surfactants, fabric softeners and anti static agents (especially in shampoos).
It acts as a formaldehyde releaser. (hmm why do we need a formaldehyde releaser ... cause all those chemicals listed above can actually creates formaldehyde??? Formaldehyde is an intermediate in the oxidation of methane as well as other carbon compounds! In view of its widespread use, toxicity, and volatility, exposure to formaldehyde is a significant consideration for human health! (must i go on ... you get the picture)
It can cause contact dermatitis, a symptom of an allergic reaction, especially in those with sensitive skin, on an infant's skin, or on sensitive areas such as the genitals ... hmm ... so why is in in a infant product?

Citric Acid - is a weak organic compound. a natural preservative and is also used to add the sour taste in foods and soda pops. used as a benign cleaning agent. and also a chelating agent.

Yellow 10 and Orange 4 - are color dyes

in the United States, quinoline yellow is certified by the Federal Food and Drug Administration and designated as D. & C. yellow No. 10. Under the provisions of the Code of Federal Regulations, it "may be safely used for coloring drugs generally in amounts consistent with current good manufacturing practice." This is precisely the function for which it was employed in the study in Finland (where quinoline yellow is approved for food use).

May also contain: Citric Acid, Sodium Hydroxide

Sodium Hydroxide - also known as lye or caustic soda ... solid sodium hydroxide or solutions of sodium hydroxide will cause chemical burns
