Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, in particular to a soothing and mild shampoo and shower gel for infants and children and a preparation method thereof. Background Art

[0002] Babies and children have delicate and sensitive skin, which can easily cause allergies or other adverse reactions to the external environment. Some baby cleaning products use chemical synthetic substances as raw materials. Although they are low-cost, they leave hidden dangers in terms of safety. They may cause skin discomfort or even allergic reactions in babies and children, which not only affects the consumer experience, but also hinders the healthy development of the industry. Therefore, the development of safe and effective baby cleaning products has become an urgent need in the market.

[0003] At present, there are two main ways to improve baby cleaning products in the market: one is to reduce the proportion of harmful additives, such as limiting the amount of preservatives, fragrances and other potential allergenic ingredients added; the other is to choose more natural and safe raw materials to replace traditional chemicals, such as plant extracts, amino acid surfactants, etc. However, the former is difficult to completely eliminate safety hazards, and the latter faces challenges such as high costs and unstable performance. In addition, some manufacturers try to enhance the functionality and safety of their products by increasing the complexity of the formula, but this often makes production more difficult and is not conducive to large-scale promotion and application.

[0004] Although the above measures can alleviate the incidence of baby skin problems to a certain extent, due to the lack of effective solutions that are highly targeted and cost-effective, most commercially available products still cannot fully meet consumers' demand for high-quality baby care products, especially in ensuring the mildness of cleaning products while maintaining good cleaning effects. The existing commercially available baby cleaning products still have much room for improvement. Summary of the invention
