DeepSnow combines a wet lab, an AI polymer discovery engine, and a developing product pipeline led by SL6733 — an ultra-high MW polymer additive engineered for a +3°C wet-bulb advantage and up to 500 additional snowmaking hours per season.
The DeepSnow Platform
DeepSnow operates a wet lab, an AI polymer discovery engine, and a developing product line — vertically integrated so chemistry, software, and commercialization stay in lock-step.
Polymer synthesis, AF4-MALS molecular-weight verification, splat assays for ice recrystallization inhibition, and full freeze-thaw characterization. Every candidate is made and measured in-house before it ever touches a snowgun.
Our discovery platform ranks candidate polymer architectures by predicted ice-binding affinity, IRI potency, and manufacturability — then proposes the next experiment for the wet lab. The engine is what produces the DS-100 and DS-400 pipeline.
DeepSnow is building a portfolio. SL6733 is targeting EU lab pilots for 2026/27 with commercial deployment in 2027/28; DS-100 and DS-400 follow on the back of the discovery engine. Adjacent verticals (ice rinks, food IRI, cold chain, cryopreservation) extend the same platform.
SL6733 · Target Operator Outcomes
The outcomes that matter for the resort operator. The headline number is the Margin Multiplier — DeepSnow's owned metric for slope-day EBITDA returned per euro of additive spend.
The SL6733 dial
How the 30-50× Margin Multiplier is actually generated. The operator chooses where to spend the chemistry's gain — push it into snow volume, or pull it out as opex savings.
Mode A · Volume
Keep your water draw and electricity bill where they are today. SL6733 is engineered for ~50% more cubic metres of snow per shift, with a finer crystal structure that melts roughly twice as slowly. The snowpack you build at +3°C wet-bulb in October lasts deeper into spring.
Mode B · Economy
Hold snow production flat against last season. SL6733 is engineered to cut water draw and electricity consumption by roughly 50% — the two largest variable costs of snowmaking. Useful where water rights, watershed limits, or grid carbon are the binding constraint.

Numbers are engineering design targets for SL6733 at 6-7.6 ppm operational dose, modelled against unaided water under marginal-condition wet-bulb. EU lab pilots are scheduled for the 2026/27 season; commercial deployment from 2027/28. Per-mountain Margin Multiplier varies with hydrology, gun fleet, operating profile, and current opex — request a pilot conversation and we'll model your specific numbers.
SL6733 · Snowmaking Polymer Additive
SL6733 is a two-component polymer additive dosed at 6-7.6 ppm. Component X is an ultra-high molecular-weight anionic poly(acrylamide-co-sodium acrylate) at 15-20 MDa — it owns the recrystallization-inhibition story. Component Y is a cold-water-swelling starch nucleator — it owns the distributed-nucleation story. Together they're engineered for ~50% more snow per shift OR ~50% less water and energy per shift, plus a +3°C wet-bulb ceiling — feeding the 30-50× Margin Multiplier.
Carboxylate (COO−) groups on Component X disrupt Ostwald ripening at growing ice surfaces — inhibiting recrystallization and producing finer, more durable snow. The starch component provides distributed nucleation sites so freezing initiates at multiple points instead of a few. Net effect: more snow per litre of water, denser surface that resists wind erosion, and a melt rate roughly half of unaided snow — which is what enables the operator-side dial between volume mode (+50% snow) and economy mode (−50% inputs).
Product Pipeline
SL6733 is the lead candidate — chemistry specced, manufacturing pathway in build, and EU resort lab pilots targeted for 2026/27. Everything else is the platform's ongoing output.
Ultra-high MW poly(acrylamide-co-sodium acrylate) + cold-water-swelling starch
Target operational dose 6-7.6 ppm. EU resort lab pilots targeted for 2026/27; commercial deployment 2027/28. Engineered as a synthetic, EU-compliant alternative to Snomax.

Regulatory & Environmental
The dominant snowmaking additive — Snomax — is a biological product restricted across France (2005 moratorium), Austria, and Bavaria. SL6733 is being engineered as the synthetic, regulatory-compliant alternative, designed to slot under existing EU and TSCA polymer frameworks.
Performance and a defensible regulatory pathway, in the same formulation.
SL6733 lab pilot · EU 2026/27 season
Lab pilot cohort enrolment for 2026/27 is targeted at EU resorts and includes integration setup, on-site dosing, snow-quality monitoring, and operator training. Limited slots.

Snomax is the dominant biological snowmaking nucleator — and it is restricted across France (2005 moratorium), Austria, and Bavaria. This is the complete guide to the alternatives: how Snomax works, how the Drift surfactant compares, and how SL6733, a synthetic polymer engineered for the EU polymer exemption, addresses the regulatory gap.

IRI is the mechanism that controls how ice crystals grow once formed. It is why snow density, durability, and melt rate vary so much between additives. Here is the physics, the chemistry, and what makes a polymer effective at it.
