Characteristics of Cosmetic-Grade Silica

Our cosmetic-grade silica is meticulously processed to ensure uniform particles and exceptional oil absorption, which are crucial for enhancing product performance and user experience. Its key characteristics include:

  • Outstanding Soft-Focus Effect: This silica effectively reduces light reflection and scattering, creating a subtle "soft focus" effect on the skin.
  • Superior Adsorbent Properties: Its remarkable adsorptive capacity helps formulations maintain a long-lasting, fresh, and matte appearance throughout the day.
  • Smooth Texture and Silky Touch: When incorporated into skincare and makeup, our silica imparts a luxuriously smooth texture and a silky, soft-focus feel to the skin.
  • Excellent Suspension and Dispersibility: It disperses readily and appears transparent when distributed in suitable carriers, ensuring homogeneous formulations without sedimentation.
  • High Purity and Formulation Flexibility: Characterized by its high purity and non-ionic surface, our silica is highly compatible with a broad range of cosmetic ingredients, including common thickeners.

Applications Across Cosmetic Categories

Cosmetic-grade silica is a multi-functional inorganic material that plays a pivotal role across numerous cosmetic formulations, leveraging its high specific surface area, excellent dispersibility, and remarkable stability.

  • Eye Makeup Products: From eye shadows to eyeliners, our silica improves color saturation, wear time, and resistance to migration. Its unique properties enhance the adherence and longevity of eye makeup, ensuring a flawless look that lasts.
  • Foundation and Facial Coverage: As an effective anti-caking and thickening agent, our silica significantly improves the stability and applicability of liquid foundations, concealers, and other facial coverage products. It also contributes to improved breathability and enhanced oil control, leading to a comfortable, long-wearing finish.
  • Lip Care Products: For lipsticks, lip glosses, and other lip care formulations, our silica acts as an anti-caking and thickening agent, contributing to enhanced stability and a smooth, consistent application. It refines the product's texture, significantly improving the user's experience.
  • Oral Care Products: In toothpaste, silica serves as an excellent abrasive and polishing agent, aiding in effective cleaning and whitening of teeth. It also acts as an adsorbent, helping to remove bacteria and plaque for improved oral hygiene.
