Making transparent gel toothpaste is challenging—choose high-transparency silica to avoid unnecessary detours.

Created on 07.13

Anyone formulating transparent toothpaste has likely run into this problem: cloudy paste, low light transmittance, and batch after batch of raw material that fails to fix it. According to 2026 QYResearch data, transparent gel toothpaste is growing at over 12% per year, yet very few suppliers can deliver consistently stable transmittance.

We are Zhongqi (Guangdong) Silicon Materials, with nearly 20 years of experience in food-grade silica. Toothpaste-grade silica is one of our core product lines. Our production base is in Zengcheng, Guangzhou, and overseas sales are handled by Shandong Zhonglian Chemical. We listed on the Guangdong Equity Exchange in 2021 (stock code 880747), are a national-level high-tech enterprise, and supply more than 30 mid-to-high-end toothpaste manufacturers in China on a long-term basis.

Our high-transparency silica series is controlled at a refractive index of around 1.44, closely matching the liquid phase of toothpaste, so finished products consistently achieve transmittance above 90%. With a tight particle size distribution, there are no oversized grains causing white specks or cloudiness. It is highly compatible with fluoride and herbal extracts, and paste transparency barely degrades after six months of ambient storage. Our combination-grade ZLDIO-TY2 is a typical example, balancing transparent appearance with basic abrasive cleaning power.

Similar high-transparency products from overseas generally come with longer lead times and higher procurement costs. Our equivalent grade ships in around 7 days and offers a more competitive unit price. We operate an in-house microbial testing lab, issue a full COA for every batch, and our entire line complies with QB/T 2346-2015. Complete product TDS files are available for download on our official website.

For whitening or fruit-flavored transparent toothpaste, choosing the right raw material saves a lot of trial and error. Request samples and test transmittance and storage stability yourself — hard data is the most convincing proof.
