BELLOCEA™consists of spherical fine particles of cellulose acetate derived from cellulose, the main component of wood, and acetic acid, the main component of vinegar.
Features
INCI Name：Cellulose acetate
・Spherical particles（Smooth surface）
・Smooth texture
・Good spreadability and dispersibility
・Provides light-diffusivity
・Average particle diameter 7μm
Comparison to synthetic resin material
BELLOCEA™with a feeling of softness, is gentle on the environment and has better spreadability than synthetic particles.

After washing BELLOCEA™ off the face, it will gradually break down into cellulose, a natural material and acetic acid, a food ingredient, through the action of water in the natural environment. Therefore, cellulose acetate is said to be a material with low environmental impact.
Safety assessment
BELLOCEA™ is composed of fine spherical particles of cellulose acetate, which is made from natural cellulose and acetic acid, the main component of vinegar, and is a substance which is highly safe for living organisms.
