Embodiment 1

[0072] Take 0.1 parts by weight of rose petals into the container; take 80 parts by weight of water into the container; take 3 parts by weight of glycerin and 4 parts of propylene glycol into the mixing container, and mix well.

[0073] Stir at a rotation speed of 10r / min and heat to 80°C, and the heating process is 20 minutes. After decolorizing at a temperature of 80° C. for 10 minutes, filtration was performed to obtain decolorized rose petals and filtrate, and the decolorized plant rose petals and filtrate were collected.

[0074] Repeat the above steps twice to obtain completely decolorized rose petals.

Embodiment 2

[0076] Take 0.3 parts by weight of rose petals into the container; take 85 parts by weight of water into the container; take 6 parts by weight of glycerin and 8 parts of propylene glycol into the mixing container, and mix well.

[0077] Stir at a rotation speed of 13r / min and heat to 85°C, and the heating process is 25 minutes. After being kept at a temperature of 85° C. and decolorizing for 60 minutes, it was filtered to obtain decolorized rose petals and filtrate, and the decolorized rose petals and filtrate were collected.

[0078] Repeat the above steps three times to obtain completely decolorized rose petals.

Embodiment 3

[0080] Take 0.5 parts by weight of safflower petals into the container; take 90 parts by weight of water into the container; take 8 parts by weight of glycerin and 10 parts of propylene glycol into the mixing container, and mix well.

[0081] Stir at a rotation speed of 15r / min and heat to 90°C, and the heating process is 30 minutes. After being kept at a temperature of 90° C. and decolorizing for 120 minutes, it was filtered to obtain decolorized safflower petals and filtrate, and the decolorized safflower petals and filtrate were collected.

[0082] Repeat the above steps four times to obtain completely decolorized safflower petals.

Abstract

The invention discloses a decoloring method for plant petals used for toning lotions, and belongs to the field of cosmetics. The decoloring method comprises the steps that the plant petals, water anda solvent are added into a container in a predetermined ratio in sequence; the plant petals, the water and the solvent are stirred and heated to a preset temperature, wherein the temperature rising process is longer than or equal to 20 minutes; heat preservation is conducted at the first temperature for decoloration, then, filtration is conducted to obtain decolored plant petals and filter liquorrespectively, and the decolored plant petals and the filter liquor are collected respectively; the decoloring process is repeated at least one time to obtain the decolored plant petals. By means of the decoloring method, the relatively complete plant petals can be obtained, and when the decolored plant petals are added into a product, the appearance of the product is better. The filter liquor canbe reused, and cost is saved.

Description

Technical field [0001] The invention relates to the field of cosmetics, in particular to a method for decolorizing plant petals added in cosmetics. Background technique [0002] Introduction of existing technology [0003] There is a kind of cosmetics on the market that add plant petals and make them suspended. Because of its elegant and novel appearance, these cosmetics are more popular among consumers. However, the pigments in the petals will slowly dissolve, causing changes in product properties and affecting product quality. Moreover, the natural pigments in the petals are not stable, and oxidation or light will cause them to change color, which will deteriorate the appearance and quality of the product. Therefore, the added plant petals generally need to be decolorized first. At present, a certain concentration of ethanol is generally used to decolorize plant petals by heating, so that the pigments in the petals can be dissolved to achieve the purpose of decolorization.
