Toilet Cleaners / WC-Gels

Toilet Cleaners / WC-Gels Challenges

When WC gel formulations are evaluated in real production, the main difficulties are usually related to rheology stability rather than cleaning chemistry.

Insufficient cling on vertical surfaces→ Reduces effective contact time with stains
Viscosity instability during storage→ Gel structure weakens over time, especially in acidic systems
Phase separation or turbidity→ Affects product appearance and consistency
Poor compatibility under low pH conditions→ Some thickeners lose efficiency in strong acid formulations
Suspension instability→ Insoluble components or additives may settle over time

Taken together, these issues point to one core challenge: Maintaining a stable gel network in a chemically aggressive environment (industry consensus)

Celotech Solution

Celotech WC gel solutions are based on three types of cellulose ethers:

Hydroxypropyl methyl cellulose (HPMC) is soluble in cold water, has good water retention and good resistance to enzymes. As a nonionic thickener, the viscosity of the thickened surfactant system is relatively stable with temperature changes.
Hydroxyethyl cellulose(HEC) has excellent performance in film formation, enzyme resistance, moisture retention, pH stability, etc., and can be used in liquid detergent and solid detergent industries.
Sodium carboxymethyl cellulose (CMC) is easily dissolved in cold water and hot water, has medium water retention. It can make toilet cleaners have rich foam, good foam stabilization effect, no stratification, no turbidity, and no dilution.

Recommended Formulation (Reference Only)

The following formulation is structured based on commonly used components in WC gel systems and aligned with the product types mentioned.

Component	Function	Celotech Product
HPMC	Primary thickener	Celopro®MK70MSL/Celopro®MK50MSL
HEC	Stability enhancer	Celopro®HLB100S
CMC	Suspension stabilizer	Celopro®CS180
Additives (fragrance, dye, preservative)	Aesthetic & protection	—

⚠Disclaimer：This formulation is provided for reference only. Actual performance may vary depending on raw materials, formulation design, and processing conditions. Laboratory validation is recommended before commercial use.

Celotech Formulations Advantages

When the formulation is properly structured, several performance benefits can be observed.

Good water retention: Celopro® cellulose ether has ability to retain moisture also contributes to the product’s overall performance, ensuring optimal cleaning results.
Good thickening effect: Our solution gives the product a gel-like consistency that clings to surfaces, allowing for prolonged contact time with stains and bacteria.
Excellent stability: It prevents the separation of chemical components during storage and transportation, suitable grades can function under low pH conditions.
Enhanced suspension stability:Celopro® cellulose ether help keep solid particles in toilet cleaners evenly distributed, preventing settling and ensuring consistent cleaning results with every use.

Applications

Based on formulation adaptability, this solution can be applied in:

Toilet bowl cleaning gels
WC rim gels
Bathroom descaling formulations
Urinal cleaning products
Acid-based sanitary cleaners

The Introduction and Application of CMC

Sodium carboxymethyl cellulose (CMC) is a cellulose derivative, an ionic cellulose gum, and owing to its unique thickening, suspending, adhesion, and water retention properties, is widely used in various industrial fields.

Application of Hydroxyethyl Cellulose (HEC)

HEC is the abbreviation of hydroxyethyl cellulose. It is a white or light yellow, odorless, non-toxic fibrous or powdered solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol), and is non-ionic soluble cellulose ethers.

Frequently Asked Questions

Can cellulose ether be used in eco-friendly products?

Yes, cellulose ethers are biodegradable and can be effectively used in eco-friendly cleaning products, aligning with sustainability goals.

How Can You Guarantee the Quality?

Always a pre-production sample for customer’s checking before mass production; Always final Inspection before shipment.

How does cellulose ether impact the shelf life of cleaners?

Cellulose ether can help stabilize formulations, reducing separation of ingredients and contributing to a longer shelf life. However, proper storage conditions are also essential.

How does cellulose ether improve cleaning performance?

By increasing the viscosity of the product, cellulose ether helps the cleaner cling to surfaces, allowing active ingredients to work more effectively over a longer period.
