Description

Natural conditioner composition for hair and preparation method and application thereof

Technical Field

The invention relates to the technical field of personal care, in particular to a composition of a natural conditioner for hair, a preparation method and application thereof.

Background

The hair conditioner is an essential component in shampoo and hair conditioner to provide excellent dry and wet combing performance. Hair conditioners commonly used in the market at present include cationic conditioners such as quaternary ammonium salts, cationic polymers; polysiloxanes and derivatives thereof; in addition, there are protein hydrolysates and derivatives thereof.

The cationic conditioner is mainly a synthetic product and has the defect of compatibility. For example, in shampoos, care should be taken as to the order and amount of ingredients added, otherwise the cationic conditioning agents will interact with the anionic surfactant and cause flocculation and affect the appearance and stability of the product. The cationic guar gum is natural in source, but the application of the cationic guar gum needs to adjust pH and hydrate firstly, and the cationic guar gum cannot be directly compatible with anionic polymers; silicones and their derivatives are also common hair conditioners, but they provide a heavy use feel. And the market advocates silicone oil-free products, so that a component which can replace silicone oil and provide excellent conditioning property needs to be found. Protein hydrolysates and their derivatives are complex, have poor odor, color and stability relative to synthetic conditioners, and are not widely used.

Due to the trend of natural environmental protection and mildness, the invention of a hair conditioner from natural sources is urgently needed.
