Components of Kiehl's shampoo
1. About Kiehl's amino acid shampoo, Taobao found the ingredient list on the bottle.
There are probably, water, sodium methyl coconut oil sulfonate, sodium coconut oil sulfate, sodium chloride (NaCl), coconut oil betaine, essence, PPG-5- cetyl polyether -20, and I won't post it later. As for the silicone oil often contained in shampoo, there is no such one, and the added surfactant is said to be not very irritating, mainly amino acid surfactant series. However, the third place is actually SLS, which ranks high in essence. I heard that this shampoo has a strong coconut fragrance, which is estimated to be a lot of essence. For sodium methyl cocoyl taurate, Baidu Academics described it as follows: "Long-chain acyl amino acid surfactants are widely used because of their extremely low irritation, non-toxicity and easy biodegradation. Coconut acyl methyl sodium taurate is a long-chain acyl amino acid surfactant, with sulfonic acid groups combined with amide groups in the molecule, which has good compatibility with anionic, nonionic and amphoteric surfactants. It is an anionic surfactant with high safety, excellent water solubility, hard water resistance, alkali resistance, acid resistance, excellent foaming property and good hand feeling after washing. It is suitable for preparing various middle and high-grade cosmetics such as shampoo, facial cleanser and bath lotion, as well as hair and hair shaping.
Sodium coconut alcohol sulfate, namely sodium dodecyl sulfate, also known as sodium dodecyl sulfate, k- 12. (According to foreign websites, sodium coconut alcohol sulfate is a mixture of k- 12, sodium octoate, sodium decyl sulfate and sodium oleate. In short, it is right to include k- 12. ) k- 12 (also known as SLS) is very irritating to eyes and skin, and it is said that it is easy to cause scalp folliculitis. I still have to think about the person who is going to wash my hair. This thing, P&G products such as Head & Shoulders are all in it. However, I heard that it is only irritating to mucous membranes and respiratory tract, so I need someone who knows how to do it.
Sodium chloride is edible salt, needless to say.
Coconut oil betaine has small irritation, mild performance, fine and stable foam, and is suitable for preparing shampoo, shower gel, facial cleanser, etc. , and can enhance the softness of hair and skin.
PPG-5-CETETH-20, this is only found to be a surfactant, and the ranking is relatively low, and the content should be small.
2. About Kiehl's olive oil shampoo
Well, mainly water, sls and ethylene glycol distearate. Her main shampoos have sls. As for ethylene glycol distearate, it is insoluble in water, but soluble in oil and alcohol. I wonder if I can wash it off when I wash my hair. Ethylene glycol stearate is dissolved or emulsified in surfactant compound after heating, and lenticular crystals will be precipitated when cooling, thus producing pearlescent luster. When used in liquid washing products, it can produce obvious pearlescent effect, increase the viscosity of products, and also have the functions of moistening skin, caring hair and antistatic. It has good compatibility with other types of surfactants and can reflect its stable pearlescent effect and thickening and conditioning function. No irritation to skin and no damage to hair. It probably means that it will make the hair look shiny, but it doesn't really shine by itself. Fortunately, there is no harm to the hair, but are there many small fragments left on the scalp? . . It suddenly occurred to me that after using it, the fragrance of lush's coconut floated to my scalp. Is this the reason? !
3. About Kiehl's Mimaifengying Shampoo
Mainly water, AES (with better hard water resistance than SLES and sls), coconut oil-based betaine and MEAAES are generally used in industrial washing, with better hard water resistance, which is found in Qingyang shampoo. However, the data show that AES is divided into two types, one is sodium salt and the other is ammonium salt. Sodium salt is generally used in detergents, while ammonium salt is less irritating to human body and is generally used in facial cleanser. The composition diagram shows that sodium salt is used in this product, which is quite irritating. Coconut amide MEA, also known as cocoyl monoethanolamine, is irritating to skin and eyes.
Experience of using Kiehl's shampoo
Ke Yan's coconut amino acid shampoo is really fragrant, which can be said to be a walking coconut tree. Better than kangaroo coconut. It is transparent and gelatinous, and its cleaning ingredients are mild amino acids and coconut oil. Amino acid is the so-called weak acid surfactant, and amino acid is also one of the components of protein, because it has side chain hydrophobic groups. Can produce rich foam, can bring cleaning effect ~ (Pseudoscience from a biology college student) Compared with ordinary sulfate, amino acids look natural and gentle, and have nourishing effect on scalp hair. Oh ~ This shampoo has an average foaming effect, and it is best to match it with a foaming bottle. Even if it doesn't, it can be rich in foam ~ suitable for dry neutral scalp, with strong cleaning power, suitable for people who wash their hair for more than two days. Can keep coconut fragrance and scalp fresh for two days. (The oil head should also work) Because it has only been used once, I can only pull these at present.
How does shampoo distinguish pH value?
There are two kinds of shampoos on the market: alkaline and acidic, and most shampoos are alkaline. Shampoo with PH greater than 7.5 is called alkaline shampoo, and shampoo with PH less than 7.5 is called acidic shampoo. However, generally using acidic shampoo, especially weak acidic shampoo is good for hair. There are still some people who are more suitable for alkaline shampoo. They should choose their own shampoo according to their hair quality. Otherwise, the scalp in weak acid environment will be neutralized into weak alkalinity, and once the acid-base balance of the scalp is unbalanced, it is difficult to maintain the balance of oil secretion.
