If you are interested, buy some surfactants yourself, and recommend betaine and amino acid surfactants.
Or you can use shampoo substitutes: soap, saponin liquid, tea seed powder, etc.
Regarding Shiseido mentioned by LS, I checked. Speiche used SLES, but Amway didn't find it, but the main ingredients of his daily necessities were actually mainstream.
(turn) the main ingredients of shampoo
1, the main surfactant. These are mainly salts with fatty chains, such as sodium dodecyl sulfate (SLS). Well, don't be too professional. Their function is to clean your hair, and they are the decider of shampoo foam.
2. Auxiliary surfactant. It consists of some amphoteric or nonionic surfactants. As the name implies, their function is to assist the main surfactants, clean hair, reduce irritation and improve the appearance of shampoo.
3. conditioner. The quality of shampoo depends on it. This component is mainly a mixture of cations with large molecular weight and small molecular weight. As we all know, hair is basically negatively charged, so these positively charged cations are easily adsorbed, giving hair a soft and easy combing effect.
4. Smooth agent. This is equally important in shampoo formula, which generally refers to some silicone oil with large molecular weight and high viscosity, which is adsorbed on the surface of each hair to form a very smooth film, making the hair smooth, healthy and natural.
5, shampoos are consistent, which inevitably requires some ingredients to be consistent.
6, the essence. There are many kinds of shampoos, including floral notes and green vanilla notes, depending on the differences between north and south, but the ultimate goal is the same, that is, to combine the product concept and bring consumers the best enjoyment.
======================================
At present, the main surfactants of shampoo on the market are almost all irritating surfactants such as SLS, SLES and AES. If you want to use shampoo at no cost, you'd better reject such ingredients. The auxiliary surfactant is generally betaine type.
I am not a professional. If there are any mistakes, please raise them. Thank you!
Actually, P.S. can't blame the manufacturer. It's not that they don't want to raise the cost, but how many people are willing to buy fifty or sixty bottles of shampoo at a time, and when a formula becomes an industry practice, few people think about it. This is different from the melamine incident. Melamine is artificially added to falsify the content of protein, and dioxane in shampoo is inevitably brought in by raw materials.
By the way, 99% of toothpaste uses sodium dodecyl sulfate (SLS). Since it's all in your mouth, why can't you wipe it on your head?
Finally, it is the most economical and convenient way to reduce the exposure to dioxane & an environmental protection trick. Please take a bath with soap!
