Embodiment 1

[0037] A water-soluble Tenaca extract prepared by the following method:

[0038] (1) Add Tenaca powder to deionized water, and mix Tenaca powder: deionized water at a mass ratio of 1:10 to obtain a mixed solution. The obtained mixed solution was subjected to ultrasonic extraction at a temperature of 45°C for 30 minutes, and filtered with a 0.45 μm microporous membrane;

[0039] (2) The filtrate obtained after filtration in step (1) is subjected to vacuum rotary evaporation with a vacuum of 0.095 MPa to obtain a water-soluble Tenaca extract.

Embodiment 2

[0041] An oil-soluble Tenaca extract prepared by the following method:

[0042] (1) Add Tenaca powder to the 80% ethanol solution, control the mass ratio of Tenaca powder and 80% ethanol solution to calculate, that is, Tenaca powder: 80% ethanol solution is 1:10 and mixed to obtain the mixed solution . The obtained mixed solution was subjected to ultrasonic extraction at a temperature of 45°C for 30 minutes, and filtered with a 0.45 μm microporous membrane;

[0043] (2) The filtrate obtained after filtration in step (1) is subjected to vacuum rotary evaporation with a vacuum degree of 0.095 MPa to obtain an oil-soluble Tenaca extract.

[0044] The water-soluble and oil-soluble Tenaca extracts obtained in Examples 1 and 2 were subjected to DPPH free radical scavenging experiments. The specific steps are as follows:

[0045] (1) Preparation of DPPH test solution

[0046] Take 0.003g of DPPH in an Erlenmeyer flask, add 60ml of ethanol, wrap the Erlenmeyer flask with aluminum foil paper, ...

Embodiment 3

[0064] The water-soluble and oil-soluble Tenaca extracts obtained in Examples 1 and 2 were added as antioxidant ingredients to the skin care cream, and calculated by mass percentage, the content and composition of the raw materials of the skin care cream were as follows:

[0065] Oil phase composition:

[0066] Shea butter 3%

[0067] Polyglycerol-3 Methyl Glucose Distearate 2%

[0068] Oil-soluble Tenaca extract 0.5%

[0069] Water phase composition:

[0070]

[0071] The above-mentioned preparation method of the skin care cream containing Tenaca extract specifically includes the following steps:

[0072] 1) Weigh the oil, oil-soluble Tenaca extract concentrate and emulsifier according to the above mass percentage, and heat it to 80°C to prepare the oil phase;

[0073] 2) Weigh the humectant, rheology modifier, water-soluble Tenaca extract concentrate and deionized water according to the above-mentioned mass percentages, and heat to 80°C to prepare the water phase;

[0074] 3) Homogenize t...

Abstract

The invention relates to a skin protection cream containing a thanaka extract and a preparation method thereof. The skin protection cream containing the thanaka extract is prepared from the followingraw material components in percentage by mass: 1-10% of skin friendly oil, 2-8% of an emulgator, 0.1-10% of an oil soluble thanaka extract, 0.1-15% of a humectant, 0.1-10% of a water soluble thanaka extract, 0.01-1% of a rheolobic modifier, 0.1-0.5% of a preservative and the balance of water. The thanaka extract can serve as an antioxidant skin protection agent to be added into an oil phase and awater phase of a cosmetic cream formula, and the whole antioxidant performance of the cream is provided. The invention further provides a formula combination capable of promoting osmosis of active substance of the skin protection cream, a finally-obtained cosmetic for the skin is natural and safe in components, the skin friendly performance is good, and meanwhile, the characteristics such as antioxidation is further achieved.

Description

Technical field [0001] The invention belongs to the field of cosmetics, and specifically relates to a skin care cream containing Tenaca extract and a preparation method thereof. Background technique [0002] Tenaka, also known as "Yellow Neem Powder". Neem is a wild tree that can be seen everywhere in Myanmar, it exudes a special fragrance. The yellow neem powder ground with yellow neem tree trunk has the functions of cooling, silt-reducing, anti-inflammatory, relieving pain, relieving itching, curing boils and preventing mosquito bites. At present, in the prior art, there are separate solutions for water extraction or alcohol extraction of Tenaca, but there is no related report that simultaneously applies the water extract and alcohol extract of Tenaca to antioxidant skin care products. Summary of the invention [0003] In order to solve the shortcomings of the prior art, the purpose of the present invention is to provide a skin care cream containing Tenaca extract and a prepar...
