Laundry pods are evolving from "single-chamber cleaning" toward "multi-chamber functionality". On one side are the stringent requirements of water-soluble films (PVA films) for dissolution rate and film compatibility; on the other is consumers’ strong demand for "clean, yet soft and fluffy" results. While multi-chamber pods solve the problem of separate storage, selecting the right raw material for the softener chamber has become a technical bottleneck for many brand owners.

Honesoft^Ⓡ QL-940 is a cold-water rapidly-dissolving esterquat — a dedicated softening active born precisely for this need. With no film restrictions, no water-temperature limits, and no formulation constraints, it is the ideal core for building next-generation "all-in-one wash & care" multi-chamber pods.

I. The Pain Points of the "Softener Chamber" in Multi-Chamber Pods — How QL-940 Solves Them

In multi-chamber pods, the softener liquid usually must be physically separated from the detergent chamber (high alkalinity, high anionic), yet it still faces three major challenges:

1. Film-dissolution risk: high-concentration actives or solvents can easily swell and dissolve the outer film, causing pods to stick together or the wall to rupture.

2. Low-temperature risk: thickening and crystallization at low temperatures lead to filling difficulties and uneven chamber filling.

3. Poor-dissolution risk: slow cold-water dissolution leaves softener residue or prevents even dispersion in the rinse water.

QL-940 addresses these pain points through targeted molecular design:

1. Cold-Water Rapid Dissolution — No Drag on Performance

QL-940 offers excellent cold-water dispersion. In 10–15°C cold water it rapidly disintegrates and disperses evenly, without "clumping" or "coating the wall" as conventional quats do. This means that whether users wash with cold water in winter or run a quick-wash cycle, QL-940 ensures the softening actives take effect promptly during the rinse stage, with fabric softness never compromised.

2. Low Viscosity, Excellent Flowability — Filling-Friendly

QL-940 is a low-viscosity flowing liquid at room temperature, with excellent low-temperature flowability.

· Winter production needs no extra heating or heat retention, reducing energy consumption;

· The filling line runs smoothly, is less prone to nozzle clogging, and improves multi-chamber filling precision;

· No crystallization or layering inside the chamber — it stays uniform even after long-term storage.

3. Excellent Film Compatibility — No Film Dissolution, No Sticking

This is one of QL-940’s core advantages.

Through special structural modification, it is extremely mild toward polyvinyl alcohol (PVA) water-soluble films. Throughout the pod’s shelf life, it will not cause excessive swelling, softening, or perforation of the water-soluble film.

· The pod surface stays dry — no sticking or caking;

· After contact with water, the film dissolves normally and QL-940 releases quickly, leaving no film debris behind.

4. Good Compatibility — Room for the "Wash + Soften" Dual-Chamber Design

Although the softener chamber and the detergent chamber are physically separated, the two will eventually meet once the pod enters the water.

QL-940 offers good formulation tolerance:

· It is highly compatible with commonly used nonionic surfactants, fragrance microcapsules, and enzymes;

· In diluted rinse water it stably delivers both softening and antistatic effects;

· When it meets the anionic residues from the detergent, a buffered formulation design prevents severe precipitation or flocculation.

III. Why Multi-Chamber Pod Brands Are All Paying Attention to QL-940

In multi-chamber pod formulation development, the softener chamber is often overlooked — yet it determines the user’s ultimate tactile experience.

· Use ordinary softener raw materials? Too high viscosity, hard to fill; low-temperature crystallization, unstable quality; film-dissolution risk, endless complaints.

· Use QL-940? Cold-water rapid dissolution, low-viscosity flow, excellent film compatibility, good compatibility.

QL-940 is not a "general-purpose" esterquat, but a dedicated grade tailor-made for multi-chamber pods. It makes "clean" and "soft & fluffy" truly happen inside a single pod — not just a marketing slogan.

IV. Application Recommendations

· Recommended uses: dedicated active for the softener chamber of multi-chamber laundry pods; concentrated softener; low-temperature fabric softener.

· Typical dosage: 20%–100% recommended in the softener-chamber formulation (depending on target softness and chamber volume).

· Formulation tip: it is recommended to combine with a small amount of nonionic surfactant or co-solvent to further optimize low-temperature flowability; keep pH in the 3.0–4.5 range to ensure system stability.
