AI Technical Summary

Technical Problem

The titanium dioxide sunscreen used in existing soft capsules has safety disputes and environmental pollution problems, and its substitutes such as calcium carbonate have poor dispersion and insufficient hiding power, which cannot meet the requirements for soft capsule preparation.

Method used

By adding a specific proportion of composite calcium carbonate and emulsifier polyglycerol fatty acid ester to the soft capsule capsule material, replacing titanium dioxide as a sunscreen agent, achieving even better light shielding, stability and production efficiency consistent with titanium dioxide.

Benefits of technology

The same light shielding and stability as titanium dioxide are achieved, while avoiding the potential health risks and environmental pollution of titanium dioxide, providing a greener, healthy and environmentally friendly light shielding solution.

Abstract

The invention discloses a novel titanium-free shading soft capsule and a preparation method thereof, and belongs to the technical field of medicines and health foods. The capsule wall material of the soft capsule comprises 35-45% of gelatin, 15-23% of glycerin, 30-40% of purified water, 3-5% of composite calcium carbonate, 0.5-0.7% of an emulsifier and 0-2% of a pigment. Wherein the composite calcium carbonate is composed of light calcium carbonate and heavy calcium carbonate. According to the soft capsule disclosed by the invention, the light calcium carbonate and the heavy calcium carbonate are compounded, and the emulsifier polyglycerol fatty acid ester in a specific proportion is matched, so that the shading effect and the stability which are equivalent to those of titanium dioxide are realized, and the potential risk of titanium dioxide on the environment and human health is reduced. Meanwhile, the production process is simplified, large-scale production is facilitated, and a safe, healthy and environment-friendly shading solution is provided.
