Synthalen W2000 1 kg

Industrial-grade acrylic thickener for large-scale gel formulation

Synthalen W2000 in a 1 kg pack is a modern cross-linked polyacrylic acid polymer designed to build stable viscosity in water and water-alcohol systems without lengthy hydration steps typical of older carbomer generations. This thickening agent is widely used far beyond a single niche market — it appears in skincare and haircare gel manufacturing, decorative cosmetics, pharmaceutical gel carriers, household chemical products, and even as a rheology modifier in textile and oilfield applications. This 1 kg format suits small-batch studio production as well as scaling toward light industrial manufacturing where formulators need a consistent raw material lot without recalculating ratios. The product belongs to the category of gelling agents and thickeners, which brings together rheology modifiers for building stable gel, emulsion, and suspension systems of varying viscosity.

The primary use of Synthalen W2000 lies in producing clear and semi-transparent body gels, hair styling gels, intimate hygiene products, and neutral gel bases meant for later fragrance and colorant addition. The polymer performs reliably in acidic and neutral environments, tolerates moderate electrolyte levels, and delivers a non-tacky, pleasant gel feel. In pharmaceutical applications it forms gel carriers for active ingredients, while in household chemicals it thickens dishwashing gels, glass cleaners, and similar formulas. Typical dosage ranges from 0.2 to 1.0 percent of the finished product weight depending on the desired gel firmness — lower levels for light textures, higher levels for dense transparent gels.

Synthalen W2000 should be dispersed into cold or room-temperature water under continuous stirring, sprinkling the powder slowly to avoid clumping since the polymer hydrates gradually. Once fully swollen, the mixture is neutralized with an alkaline agent to trigger thickening almost instantly. Water temperature should not exceed 40 degrees Celsius during addition, as heat slows polymer chain hydration. It pairs well with most surfactants, glycerin, moderate alcohol levels, and water-soluble extracts. For formulations requiring dual rheological support, formulators often combine it with Worlee Aqua Thix 150 to reinforce stability under elevated storage temperatures.

For softer, more natural-feeling textures, part of the carbomer can be replaced with natural polysaccharides — guar gum works particularly well here, adding a creamy consistency without affecting the clarity of the base gel. When a formula involves oil phases that need thickening without water, Covasilic 15 becomes useful, allowing formulators to build anhydrous oil gels with a transparent structure.

Synthalen W2000 should be stored in a tightly sealed container, in a dry room at room temperature, away from moisture and direct sunlight, since exposure to air causes the polymer to absorb moisture and lose its free-flowing texture, complicating precise dosing. Under proper storage conditions the shelf life typically exceeds two years.

Clear cooling body gel for warm climates

Distilled water 975 ml

Synthalen W2000 5 g

Glycerin 25 g

Panthenol 10 g

Menthol crystals or mint extract 3 g

Neutralizing agent 3 g

Preservative 8 ml

Slowly sprinkle Synthalen W2000 into room-temperature distilled water while stirring continuously, then let it hydrate for 30 to 40 minutes without disturbance. Add glycerin and panthenol, mixing until uniform, then introduce the neutralizing agent gradually until the desired gel thickness forms. Finally blend in the menthol or mint extract along with the preservative, stirring gently at low speed to prevent air bubbles, and transfer the finished gel into clean storage containers.
