Abstract

The invention relates to the field of cosmetics, and is characterized in that hydrolat, aminobutyric acid and other cosmetic functional substances and cosmetic auxiliary functional substances are used for preparing hydrolat (toner), and the product of the hydrolat (toner) has the effects of resisting oxidation and aging and removing wrinkles, and meets the requirements of people on daily skin care.

Description

Preparation of hydrolat amino butyric acid toner (toning lotion)
Technical Field
The invention relates to the field of cosmetics, and discloses a hydrosol aminobutyric acid solvent toner (astringent) prepared from hydrosol, aminobutyric acid and other cosmetic functional substances and cosmetic auxiliary functional substances.
Background
The toner (astringent) sold in the market lacks products with the effects of high-efficiency oxidation resistance, aging resistance and wrinkle reduction, so that people urgently need a high-quality toner (astringent) which meets the daily skin care needs of people.
Disclosure of Invention
The invention aims to produce high-quality antioxidant toner (astringent), and provides a hydrosol aminobutyric acid solvent toner (astringent) prepared from hydrosol, aminobutyric acid and other cosmetic functional substances and cosmetic auxiliary functional substances.
The hydrolat is a 100% saturated solution prepared from natural flowers, plant roots, stems, leaves, pericarps and fruits, contains various aromatic organic components of flowers and plants, and has good effects of keeping moisture, whitening skin, moistening skin and removing wrinkles on skin, such as Lavender hydrolat, Santalum album, tea tree hydrolat, jasmine hydrolat and rose hydrolat. The hydroluses are various weight arrangements of all hydroluses.
Aminobutyric acid refers to a chemically synthesized or biologically fermented natural extract, CAS 56-12-2, and has antioxidant, anti-aging and wrinkle-removing effects.
The hydrolat and the aminobutyric acid are combined in any proportion by weight, and the hydrolat and the aminobutyric acid are reasonably combined to play a role in synergistically caring the skin, so that the skin is better protected.
The formula is further added with other functional substances of cosmetics, such as hyaluronic acid and sodium salt, polypeptide, oligopeptide, vitronectin, ectoine, nicotinamide, vitamin C glucoside, decarboxylated carnosine, ergothioneine and glabridin. Has effects of keeping moisture, resisting oxidation, and caring skin.
