What is a surfactant shampoo?
Surfactants are molecular compounds that act as cleansing agents in shampoos and conditioning agents in (you guessed it) conditioners. They are the cleaning part of wash day– without surfactants, you wouldn’t cleanse your hair at all when using shampoo.
What is a nonionic surfactant?
Nonionic surfactants contain no charge. They are commonly found in laundry and dishwasher detergents. They are the second most widely used surfactants after anionic. These molecules have no charge and so they are less likely to form a ‘soap scum’ in hard water.
Which surfactant is best for hair?
Cocamidopropyl betaine and coco-betaine are the most commonly used amphoteric secondary surfactants in shampoo products. Cocamidopropyl betaine is by far the most widely used. Cocamidopropyl betaine is normally obtained as a 30% aqueous solution 60.
Are surfactants good for hair?
Shampoo surfactants leave a small negative charge on hair which lifts the hair cuticles. The positive charge on cationic surfactants helps remove the negative charge smoothing down the cuticle. The table below summarizes the benefits of cationic surfactants used in hair-conditioner formulations.
Is hair conditioner a surfactant?
The main component of conditioner is a cationic surfactant such as cetyl alcohol. This sticks to the surface of the hair by static attraction, because the hair carries a slight negative charge when wet, so the positively charged head group of the surfactant is attracted to it.
Are surfactants bad for curly hair?
They are highly effective at removing dirt and oil from the hair and scalp. Many consumers with delicate, curly hair find these to be too drying and damaging for frequent use, and they either seek shampoos with different types of surfactants or opt to use cleansing conditioners.
What is the example of non-ionic surfactants?
Examples of nonionic surfactant molecules are monoglyceride of long-chain fatty acids, polyoxyethylenated alkylphenol, and polyoxyethylenated alcohol (Rosen and Kunjappu, 2012).
What is the purpose of non-ionic surfactants?
Nonionic surfactants represent a major component material for applications ranging from personal care to a wide range of industrial uses. Structurally, nonionic surfactants combine uncharged hydrophilic and hydrophobic group that make them effective in wetting and spreading and as emulsifiers and foaming agents.
Are non ionic surfactants safe?
Ingestion of anionic and nonionic surfactants most commonly result in mild and self-limiting gastrointestinal upset. They can cause irritation to the skin and eye; rarely aspiration or caustic injury to the gastrointestinal tract may occur.
Why is surfactant used in shampoo?
For this reason, surface active agents (surfactants) are included in personal care cleaning products. The main purposes of surfactants are to lower the interfacial tension between the soil and the substrate, to emulsify and/or solubilize oily soils, and to disperse particulate matter.
What is the foaming agent in shampoo?
sodium lauryl sulfate
You may be surprised at just how many shampoos and other beauty products contain sulfates such as sodium lauryl sulfate, or SLS. SLS is an emulsifier and foaming agent that helps soaps, shampoos and cleansers create a foamy lather that makes skin and hair feel clean.
What shampoo should not be used for curly hair?

What shampoo is bad for curly hair?
In general, unless your curls are in need of a clarifying rinse, you should avoid shampoos that contain harsh sulfates, like sodium lauryl sulfate, ammonium lauryl sulfate, and sodium laureth sulfate.
Is Dawn detergent a nonionic surfactant?
Nonionic surfactants have molecules with no electrical charge, which makes them resistant to water hardness deactivation. This makes them good for use in laundry detergents, toilet bowl cleaners and dishwashing detergents.
What is the main advantage of nonionic surfactants?
Non-ionic polymeric surfactants have a major advantage with respect to other non-ionic surfactants, that is having a high degree of freedom for tailoring the overall size and HLB of the molecule, as well as the location of the hydrophilic/hydrophobic groups and their distribution.
What are examples of nonionic surfactants?
What are examples of non ionic surfactants?
What do surfactants do hair?
Surfactants are molecular compounds in shampoo that serve as cleansing agents. They lather in your hair, and they lift dirt, grime, dead skin cells, product residue, oils, and more from your hair.
