Octadecyl Dimethyl Betaine in Shampoo Formulation
1. Cleansing effect:
Octadecyl Dimethyl Betaine can effectively reduce the surface tension of water. In shampoos, when it is mixed with water, the hydrophobic part of the molecule (octadecyl) adsorbs on the surface of grease and other dirt, while the hydrophilic part interacts with water. During the washing process, it can take the dirt away from the surface of the hair and scalp through mechanical rubbing and other actions, which provides a cleansing effect. Compared with other surfactants, it has a milder cleansing ability and does not excessively remove natural oils from the hair and scalp, avoiding over-drying of the hair and imbalance of the scalp's oil secretion.
2. Regulates foam performance:
Octadecyl Dimethyl Betaine has an important role in regulating the foam performance of shampoo. On the one hand, it increases the stability and richness of the foam. When shampooing, consumers usually expect a rich, creamy lather, and octadecyl dimethyl betaine can help achieve this. On the other hand, it also improves the quality of the foam, making it more creamy, longer lasting, and not disappearing as quickly during rinsing, giving the user a better shampooing experience.
3. Regulates viscosity:
Octadecyl Dimethyl Betaine can be used as a viscosity regulator in shampoo formulations. By adjusting its content in the formulation, the rheological properties of the shampoo can be altered so that the shampoo has the right viscosity. The proper viscosity helps the shampoo to adhere better to the hair and scalp during use, facilitates application and rubbing, and ensures stability in the bottle, preventing the shampoo from being too thin or too thick for use and storage.
4. Conditioning effect on hair and scalp:
Octadecyl Dimethyl Betaine has a conditioning effect on hair and scalp due to its mild nature. It reduces the irritation that other surfactants may cause to the hair and scalp. It also forms a protective film on the surface of the hair after cleansing, making it softer and smoother. For the scalp, it helps maintain a healthy scalp without disrupting the microbial balance of the scalp and improves scalp comfort.
