Product Overview

The Liquid Silicone Facial Cleanser Brush Head from 橡楚（湖北）橡胶有限公司 is a custom-molded liquid silicone rubber (LSR) component designed for electric and manual facial cleansing devices. Engineered to meet the high hygiene, softness, and durability requirements of personal skincare products, our LSR brush head balances gentle exfoliation with effective pore cleansing, making it ideal for daily skincare routines for all skin types.

Unlike traditional bristle brush heads or low-quality solid silicone alternatives, our liquid silicone formula delivers uniform softness across the entire brushing surface, eliminates bristle shedding, and resists bacterial growth better than porous non-silicone materials. As a specialized LSR manufacturer, we produce this brush head using precision injection molding, ensuring consistent bristle shape, size, and flexibility for every unit, with customizable designs to fit most standard facial cleanser device platforms.

Physical Performance

Process Parameters

All our Liquid Silicone Facial Cleanser Brush Heads are manufactured via precision LSR injection molding with the following controlled process parameters:

• Molding temperature: 160°C – 180°C
• Injection pressure: 8 – 12 MPa
• Cure time: 60 – 90 seconds (depending on brush head size)
• Post-cure treatment: 4 hours at 120°C to eliminate residual volatile compounds
• Tolerance control: ±0.1mm for critical dimensions (bristle height, base outer diameter) per ISO 3302-1 M2 tolerance grade

Product Advantages

1. Gentle on Sensitive Skin

Our low-hardness LSR formulation delivers an ultra-soft contact surface that massages the skin without causing micro-scratches, unlike harsh nylon bristles or over-stiff solid silicone alternatives. The tapered bristle design flexes with facial contours, applying consistent pressure that will not irritate sensitive, acne-prone, or barrier-damaged skin, even with daily use.

2. Superior Hygiene and Durability

Liquid silicone rubber has a non-porous surface that prevents buildup of leftover cleanser, dead skin cells, and moisture, the main causes of bacterial and mold growth in brush heads. Our brush heads can be rinsed clean in seconds, and resist degradation from repeated exposure to skincare products, UV disinfection, and hot water. With proper care, our LSR brush heads maintain their flexibility and shape for up to 12 months of regular use, outlasting traditional nylon bristle alternatives by 2–3 times.

3. Precision Customization for Device Makers

As a specialized LSR manufacturer, we offer full customization of bristle density, bristle length, hardness distribution, base shape, and mounting interface to match your existing facial cleanser device designs. Our precision injection molding process ensures uniform bristle alignment and consistent performance across production batches, whether you need 1000 prototype units or 1,000,000 mass-produced units.

4. Compliance with Global Personal Care Regulations

All our Liquid Silicone Facial Cleanser Brush Heads are manufactured from raw materials that comply with major global personal care safety standards, including EU REACH registration requirements and U.S. FDA food contact safety guidelines (for skin contact applications). We provide full material safety data sheets (MSDS) and biocompatibility testing reports for all production batches to support our customers' product registration.

Applications

Our Liquid Silicone Facial Cleanser Brush Heads are suitable for a wide range of facial cleansing and skincare applications:

1. Electric rotating facial cleansing devices: As a replacement or original equipment brush head for rechargeable electric facial cleansers, the flexible LSR bristles work with device rotation or oscillation to provide deeper pore cleansing than manual washing.
2. Manual silicone facial cleansing brushes: Integrated molded brush heads for handheld manual facial cleansing tools, designed for travel and at-home daily use.
3. Sonic vibration facial cleansing devices: The low modulus LSR material efficiently transmits sonic vibration from the device handle to the bristle tips, enhancing the pore-cleansing effect without causing unnecessary skin irritation.
4. Exfoliation treatment tools: Medium-hardness variants are suitable for weekly gentle exfoliation, removing dead skin cells to improve skin texture and support absorption of subsequent skincare products.
5. Body cleansing brush attachments: Larger-sized variants can be used as brush head attachments for electric body cleansing devices, suitable for use on arms, legs, and back for gentle full-body exfoliation.

Selection Guide

Hardness Selection

We offer three standard hardness options to match different skincare needs:

• 10 Shore A: Ultra-soft, recommended for users with sensitive skin, rosacea, or damaged skin barriers, for daily gentle cleansing
• 20 Shore A: Standard softness, recommended for most skin types (normal, combination, oily) for daily use, balancing gentleness and cleansing effectiveness
• 30 Shore A: Medium softness, recommended for users with thick, oily skin or for weekly deep exfoliation routines

Size Specifications

We offer standard sizes to fit common facial cleanser device platforms, including:

• 28mm diameter: Compact size for targeted cleansing of the T-zone and around the nose
• 38 – 45mm diameter: Standard full-face size, suitable for most full-facial cleansing devices
• 55mm+ diameter: Oversized size for body cleansing applications

We also accept custom size and shape requests to match your specific device design requirements.

Material Grade

We offer two standard material grades for different market requirements:

• General personal care grade: Suitable for mainstream consumer skincare products, meets all basic safety requirements for prolonged skin contact
• Medical-grade LSR: For clinical skincare devices or products targeting users with extremely sensitive skin, with additional testing for residual monomers and cytotoxicity to meet stricter safety requirements

Quality Assurance

At 橡楚（湖北）橡胶有限公司, we implement strict quality control in full compliance with our ISO 9001 certified quality management system, from raw material incoming inspection to final product shipment. Every production batch undergoes the following inspections before delivery:

1. Raw material verification: All incoming LSR raw materials are tested for hardness, volatility, and impurity content to ensure compliance with our material specifications
2. In-process dimension inspection: Critical dimensions (base diameter, bristle height, mounting interface tolerance) are inspected every 2 hours during production to ensure consistency
3. Finished product visual inspection: 100% visual inspection to eliminate defects such as incomplete molding, burrs, or discoloration
4. Functional testing: Random sampling of every batch for flexibility, compression set, and surface finish testing
5. Safety documentation: We provide full batch traceability and all required safety documentation to support customer product compliance
