Description

Composition containing plant essential oil, preparation method thereof and shampoo composition containing plant essential oil composition

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a composition containing plant essential oil, a preparation method of the composition and a shampoo composition containing the plant essential oil composition.

Background

With the continuous improvement of living standard, people have higher and higher requirements on the functionality and the quality of raw materials of hair products (such as shampoo, hair conditioner and the like). For example, the fragrance of hair products is an important aspect of consumer interest. The traditional shampoo is generally endowed with fragrance by adding higher content of essence (usually 0.5-1.5%), but synthetic essence raw materials often bring safety concerns to consumers, and the essence generally has no hair care function. The plant essential oil is an aromatic substance extracted from natural plants, is a high-grade cosmetic raw material, is used for repairing hair and improving hair quality in hair products, and has the characteristics of natural and fragrant smell.

At present, a plurality of technical reports about plant essential oil and application thereof in hair products exist. Most of the published patent technologies focus on the functions and applications of specific kinds of plant essential oils and compositions thereof, and essential oils can exert better effects in leave-on products (such as skin care products, leave-on hair care essences and the like), but when applied in rinse-off products (such as shampoos, rinse-off conditioners and the like), most of essential oils are washed away during rinsing, so that deposition on hair is limited, and ideal effects are difficult to exert; since essential oils are expensive, increasing the amount of deposition by increasing the amount of addition increases costs. Therefore, there remains a technical difficulty in effectively increasing the deposition of plant essential oils on hair in rinse-off hair products.
