SIENOX Cosmetic Raw‑Material Solutions

Working Condition Requirements

• Material Type: Cosmetic raw materials (creams, lotions, essences, foundation liquids, sunscreens, mask essences, etc.)

• Initial Status: A large number of micro‑scale bubbles are mixed into cosmetic raw materials during emulsification and filling processes, resulting in rough paste surface and uneven texture. Voids and depressions appear after filling, which impair product appearance, skin‑feel and shelf life.

• Treatment Target: Uniformly remove micro‑scale bubbles from cosmetic raw materials to achieve fine and even paste / liquid texture. Ensure smooth and flat surface without bubble voids after filling for exquisite appearance, comfortable skin‑feel and stable shelf‑life performance.

Comparison Before and After Improvement

Before Improvement — Pain Points of Traditional Processes

The quality of cosmetic raw materials directly determines product appearance, skin‑feel and consumer experience. Nevertheless, raw materials such as creams, lotions and essences easily trap bubbles during emulsification and filling, bringing multiple challenges to conventional processing:

• Appearance defects caused by bubbles: Residual bubbles in paste lead to depressions and pores on filled products with rough appearance, which greatly damages brand image.

• Uneven texture: Traditional stirring fails to fully eliminate micro‑bubbles trapped inside paste, resulting in uneven texture and rough skin‑feel upon application.

• Impaired filling accuracy: Bubbles occupy volume and cause unstable filling weight, leading to net‑content fluctuation within batches and potential metering complaints.

• Shortened shelf life: Residual bubbles accelerate paste oxidation and active‑ingredient degradation, shortening product shelf life.

• Component damage from high‑speed dispersion: Excessive shear force of conventional high‑speed homogenizers may break emulsion stability and damage active ingredients (Vitamin C, hyaluronic acid, etc.) and reduce product efficacy.

Solutions

• Vacuum Defoaming + Planetary Motion: Under vacuum conditions, gentle and uniform shear and convection generated by rotation‑revolution planetary motion make micro‑scale bubbles in paste rise gradually and be extracted for thorough defoaming.

• Gentle Non‑destructive Mixing: Planetary motion delivers 360° dead‑zone‑free mixing without breaking emulsion stability or harming active ingredients, preserving original product efficacy.

• Fine & Uniform Texture: Treated paste features fine and even texture, smooth flat surface after filling and comfortable skin‑feel.

• Improved Filling Accuracy: Stable paste density after defoaming brings consistent filling volume with minor net‑content deviation.

Advantages of Mixing‑Defoaming Machine

• Efficient Removal of Micro‑Scale Bubbles: Vacuum environment combined with planetary motion effectively eliminates micro‑sized bubbles in paste or liquid, eliminating hidden risks of depressions and pores after filling.

• Gentle Non‑destructive Mixing: Mild uniform rotation‑revolution planetary motion protects emulsion system and active ingredients from damage.

• Precisely Controllable Parameters: Adjustable rotating speed, time and vacuum degree for accurate process‑parameter optimization for different formulas (creams, lotions, essences, etc.).

• Fine & Uniform Texture: Processed paste is smooth and homogeneous with flat surface after filling and pleasant skin‑feel.

• High Efficiency & Time‑Saving: The whole mixing‑defoaming process completes within several minutes, greatly improving production efficiency.

• Compatible with Multiple Formulations: Suitable for creams, lotions, essences, foundation liquids, sunscreens, mask essences and many other cosmetic raw materials.
