Spherical Cellulose

AME0005A Spherical Cellulose Package： Function: Application: Tags: Beauty

Spherical cellulose is a kind of microporous spherical bead like cellulose, which is obtained by saponification of CA-77 with alkaline solution, filtration, washing and drying with water.

Their characteristics include soft touch, low skin irritation and good air permeability, and they have been mainly developed for cosmetic ingredients. Because they have proper oil absorption and small proportion, compared with traditional inorganic fine particles, they make cosmetics have good texture and excellent performance by being wrapped in cosmetics.

Spherical cellulose acetate and spherical cellulose have the following characteristics:

1) sphere

2) High physical strength

3) Highly porous.

They are very useful for the preparation of cosmetics. They absorb oil, fat and sweat, giving stable makeup and relaxed texture. Because of their absorption of too much oil and moisture, they have a wide space for use. It will not agglomerate when making pressed cosmetics.

4) It is smooth and moisturized with little coalescence. The dispersibility is very good. Compared with other spherical examples, they are less agglomerative, so they don't need to do too much particle separation when making cosmetics. They can be used to make emulsion cosmetics and skin care lotion without agglomeration, stability and preservation.

5) Safe, non-toxic and low irritation.

6) Excellent chemical resistance.

7) Compatible with water and oil.

[2] uses:

Spherical cellulose acetate and spherical cellulose are very effective in the following applications:

1) cosmetic ingredients such as granular, emulsified cosmetics, lotion, lipstick and eye shadow.

2) Drug release support.

3) Adhesive additive for toner.

4) Modifiers for pigments and paints.

5) Composite particles (surface hybridization of titanium dioxide, etc., hyaluronic acid hybridization)

[3] difference between spherical cellulose acetate and spherical cellulose

1) Spherical cellulose is composed of cellulose and spherical cellulose acetate is composed of cellulose acetate (degree of acetylation: 58-60%).

2) Spherical cellulose and spherical cellulose acetate are difficult to dissolve in water. Spherical cellulose only dissolves in specific solvents, CA-77 is more lipophilic and dichloromethane and chloroform.

3) The total pore area and specific surface area of spherical cellulose acetate are larger than those of spherical cellulose acetate, so it is more porous.

4) Spherical cellulose and spherical cellulose acetate should be selected properly according to the use.
