High Oil Absorption Silica
Classification :
Toothpaste Silicon Dioxide
Keywords :
High Oil Absorption Silica
PRODUCT DETAILS
1. Product Advantages
This is a high oil‑absorption silica specially developed for toothpaste. Manufactured via modified technology with high‑porosity porous structure, it fully complies with GB/T 32673‑2016 and FDA standards. Its oil‑absorption value reaches 180‑280 g/100 g, much higher than conventional toothpaste‑grade silica materials.
Thanks to high specific surface area and abundant microporous structure, it efficiently adsorbs excess oil, perfume oil and residual impurities within toothpaste systems. It effectively solves common problems of oil‑formula toothpaste such as soft paste, oil bleeding, phase separation and faded flavor.
With silica content ≥98%, the product delivers excellent compatibility and will not impair active ingredients in toothpaste. It also brings favourable thickening and paste‑stabilizing effects, improving paste fineness and formability for long‑term paste stability. It is well‑suited for high‑end toothpaste formulas containing oils and essential oils.

3. Application Scenarios
Primarily applicable to oil‑based formula toothpastes, including essential‑oil toothpaste, plant‑based care toothpaste, herbal‑oil formula toothpaste, long‑lasting fragrance toothpaste and high‑end aroma toothpaste.
It effectively adsorbs excess plant oils, essential oils and perfume oils in formulas, resolving industry pain points such as oil exudation, soft paste, phase separation and tube collapse, as well as fragrance fading during long‑term storage. Its porous structure locks perfume components to extend fragrance retention. It also enhances paste compactness and smooth texture, greatly improving the appearance, touch and user experience of high‑end toothpaste.
4. Factory Advantages
Our company holds patented technology for high‑porosity modification, enabling precise adjustment of powder microporous structure and oil‑absorption value with stable performance and minimal batch‑to‑batch deviation.
We are equipped with specific testing instruments including specific‑surface‑area analyzers and dedicated oil‑absorption testers to monitor pore structure and adsorption performance throughout production. Specialized QC procedures for modification processes cover 26 full‑range inspection items to guarantee adsorption performance and product stability.
Our 10,000‑ton‑level modified production line supports mass and consistent supply. We provide custom raw‑material solutions for high‑end functional toothpaste manufacturers, compatible with various complex oil‑based formula systems.
5. Shipping & Packaging
- Standard Packaging: 10/20 kg high‑seal valve paper bags to prevent premature moisture and oil absorption.
- Moisture‑proof Design: Thickened sealed inner liner plus outer waterproof protection to stabilize powder pore structure.
- Storage & Transportation: Store in cool, dry and sealed conditions, isolated from grease and moisture. Shelf life: 24 months.
- Marking Specifications: Marked with special high‑oil‑absorption parameters and applicable standards; custom shipping marks are supported.
6. Frequently Asked Questions
Q: Will high oil‑absorption silica adsorb active ingredients in toothpaste?
A: No. Modified for selective adsorption, this product preferentially captures free excess oil instead of water‑soluble active repair ingredients, and will not compromise core toothpaste efficacy.
Q: Is it suitable for essential‑oil‑added toothpaste?
A: Highly suitable. It perfectly addresses oil bleeding, phase separation and short fragrance retention of essential‑oil toothpaste. It stabilizes paste while locking essential‑oil aroma.
Q: Can the oil‑absorption value be customized according to formulas?
A: Yes. Our technical team can customize oil‑absorption specifications based on customers’ oil dosage to optimize formula stability.
