Method for preparing hair care extract

Abstract

The invention relates to a method for preparing a hair care extract and belongs to the field of preparation of natural extracts. The method comprises the following steps: 1) wetting Chinaberry seeds with water, adding yeasts for fermenting in a sealed manner for 1-3 days, adding water to soak for 1-3 hours at a soaking temperature of 40-50 DEG C after fermentation, filtering to take filter residues, and draining; 2) mixing and grinding the drained Chinaberry seeds and chamomile according to a weight ratio of 1:(0.1-3), adding the ground substance into an alkaline solution, hydrolyzing with cellulase, pectinase and papain, and performing enzyme deactivation after hydrolysis so as to obtain enzymatic hydrolysate; and 3) concentrating the enzymatic hydrolysate, adding coconut oil and olive oil into the concentrated solution, performing vapor reflux extraction, and performing oil-water separation on the extract, thereby obtaining an oil phase, namely the hair care extract. The hair care extract obtained by the method is mild in property and excellent in hair care effect, can be added into products such as shampoo and hair conditioners and has wide application range.

Description

technical field

[0001] The invention relates to a preparation method of a plant extract, in particular to a preparation method of a hair care extract. Background technique

[0002] Neem, a common traditional Chinese medicine, is the fruit of Melia azedarach L., a plant of Meliaceae. Neem has the effects of promoting qi and relieving pain, killing insects and sterilizing bacteria, and can be used to treat scabies, chilblains, and tinea capitis. Chamomile is a plant of Compositae, native to Europe, also known as Roman chamomile and German chamomile. It is also cultivated in large quantities in some areas of China for use as medicine and tea. Chamomile can help sleep, relieve inflammation and pain symptoms of patients, and relieve insomnia caused by nervous skin itching. Therefore, chamomile essential oil extracted from chamomile is very popular in health care and medicinal products. At present, there is no patent publication that combines neem and chamomile to prepare an e...

[0019] The preparation method of hair care extract comprises the following steps:

[0020] 1) Wet neem seeds with water, then add yeast to seal and ferment for 1 day, add water and soak for 2 hours after fermentation, soaking temperature is 50°C, filter to take filter residue, drain, and obtain pretreated neem seeds;

[0021] 2) Mix and pulverize the pretreated neem fruit and chamomile flower in a weight ratio of 1:0.1, add the pulverized product into an alkaline solution, and hydrolyze it with an enzyme preparation containing cellulase, pectinase and papain, and after hydrolysis Inactivate the enzyme (boiling for 10 minutes) to obtain the enzymolysis solution;

[0022] 3) Concentrate the enzymatic hydrolysis solution to a relative density of 1.05, add coconut oil and olive oil to the concentrated solution, and reflux the water vapor for extraction for 5 hours. After the extract is separated from oil and water, the oil phase obtained is the hair care extract.
