Why shampoo is an organic compound?
Natural shampoos contain natural plant extracts that help the hair and scalp in many forms without using the chemicals. Organic shampoos infuse natural oils, minerals and herbal extracts into the hair follicles to maintain moisture. They also make the hair more healthy and repair the damaged hair.
How does shampoo work chemistry?
Shampoo contains detergent, much like you would find in dishwashing or laundry detergent or bath gel. Detergents work as surfactants.They lower the surface tension of water, making it less likely to stick to itself and more able to bind with oils and soiling particles.
Where is shampoo on the pH scale?
between 3.5 to 9 Most shampoos are between 3.5 to 9 on the pH scale, which is a pretty wide range. If you are using a shampoo that is too high or too low on the pH scale, then you might be interfering with your scalp’s natural pH balance, causing hair damage and scalp irritation.

Is Baby shampoo acidic or basic?
Technically, baby shampoos are neutral; they have a pH of around 7, since most are designed to be ‘tear free’ and 7 is actually the pH of your tears. But just because they’re gentle on the eyes, doesn’t mean they’re gentle on the hair. Your hair freaks out at pH 7 – which is way higher than its favourite 3.67.
Why does shampoo separate?
Surfactants decrease the interfacial tension between two physical states. In shampoo, surfactants allow for oil and water to get along with each other and form a uniform liquid called an emulsion. If oil and water did not get along, you would see two liquids sitting on top of each other, separated, in the bottle.
