Application of phellinus igniarius polysaccharide II in preparing moisturizers and moisturizing cosmetics

Abstract

The invention provides an application of phellinus igniarius polysaccharide II in preparing moisturizers and moisturizing cosmetics. The phellinus igniarius polysaccharide II provided by the invention has good moisturizing activity, can be used to prepare moisturizers, especially moisturizing cosmetics, and has good application prospect.

Description

Technical field:

[0001] The invention belongs to the field of biotechnology and fine chemical industry, and in particular relates to the application of the polysaccharide II of Acupunculatus polysaccharides in the preparation of moisturizing agents and moisturizing cosmetics. Background technique:

[0002] Moisturizing is an important condition to ensure skin health and delay aging. To make the skin soft and elastic, the water content of the stratum corneum should be kept between 10% and 20%. If the water content of the stratum corneum is lower than 10%, the skin will be dry, rough or even chapped, and in severe cases, it will cause inflammation, resulting in dermatitis, eczema, psoriasis and other skin diseases. Humectant is a kind of substance with moisturizing effect. It is an important part of people's daily skin care products. It has the functions of maintaining moisture in the stratum corneum, maintaining skin elasticity, and promoting the repair of skin barrier funct...

Examples

Embodiment 1

[0011] Weigh 2.0 g each of the samples of Acupuncture polysaccharide II (prepared according to the preparation method of Acupuncture polysaccharide II disclosed in ZL200810028951.4), positive control (hyaluronic acid, glycerin), and add the samples respectively to the In the petri dish, 4 samples were weighed for each sample. Place them in an oven at 60°C to dry to constant weight and weigh, and the weight is the weight before placing (W 0 ). Place 2 of the petri dishes in a desiccator with a saturated solution of potassium acetate and a relative humidity (RH) of 43%, and the other 2 petri dishes in a desiccator with a saturated solution of ammonium sulfate and a relative humidity of 81%. . Weigh the mass of the sample (W n ), and then calculate the moisture absorption rate according to the following formula: moisture absorption rate / %=100(W n -W 0 ) / W 0 , and calculate the average of the 2 samples. Calculate the water content H of the sample before placing it in the dr...

Embodiment 2

[0017] Embodiment 2: method is with embodiment 1, and result is as follows

[0018] Table 3: Determination results of moisture absorption rate

[0019]

[0020] Table 4: Determination results of moisture retention rate

[0021]

[0022] From Example 1 and Example 2, it can be seen that under low and high humidity environments, the moisture absorption rate of Acupuncture polysaccharide II is equivalent to that of hyaluronic acid, and the moisture retention rate is equivalent to that of glycerin. It has very good moisturizing activity and can be used to prepare Humectants, especially moisturizing cosmetics.

Embodiment 3

[0023] Example 3: Adding Acupunculopolysaccharide II to cosmetics to prepare moisturizing cream.

[0024]

[0025] Preparation method: heat phase A and phase B to 80°C, mix, homogenize for 5 minutes, stir at constant temperature for 10 minutes, add phase C, add dissolved phase D when cooling to 50°C, add E when continuing to cool to 40°C Just blend and get a moisturizer.

[0026] The moisturizing cream of embodiment has good moisturizing effect through trial.
