DOWCLENE 1601
The Best of Both Worlds
Blending Hydrophilic and Lipophilic Qualities Serves Up Versatility,
Exceptional Cleaning
DOWCLENE 1601, a modified alcohol (alkoxy propanol), is a popular choice for metal cleaning due to its highly
effective cleaning capability. The structure of DOWCLENE 1601 is the key to its effectiveness. DOWCLENE 1601 has both
hydrophilic (“water-loving”) and lipophilic (“oil-loving”) portions in the structure, behaving similar to a surfactant (surface
active agent used in cleaning formulations). This versatile feature enables DOWCLENE 1601 to effectively isolate soil
particles and remove them from metal surfaces without re-depositing them, so the parts dry without residue. With both
hydrophilic and lipophilic characteristics, DOWCLENE 1601 offers exceptional solvency for a broad range of soils
and contaminants.
Unlike typical surfactant-based cleaners, which have limited use before requiring disposal, DOWCLENE 1601 can be
distilled to separate it from contaminants, and then re-used, resulting in a recyclable solvent. That means longer cleaning
fluid life and less money wasted on re-work or solvent replacement.
Applications
DOWCLENE 1601 Cleaning Fluid is suitable
for a variety of high performance metal
cleaning applications for industries including
automotive and aerospace. The low surface
tension of DOWCLENE 1601 makes it ideal
for applications requiring cleaning of complex
parts with small grooves or blind holes.
DOWCLENE 1601 is highly effective for
cleaning metal parts at virtually any process
step, including:
• Before and after processing or assembly
• Prior to finishing steps such as painting,
coating, welding, adhesion or sealing
• As a final cleaning step to meet quality
requirements

DOWCLENE 1601 is a combustible liquid/vapor. For vapor degreasing applications, DOWCLENE 1601 must be used in
a vacuum degreaser. DOWCLENE 1601 may be used in cold cleaning applications, with proper ventilation and personal
protective equipment, and in adherence to the guidelines in the Material Safety Data Sheet, as well as any federal, state
or local regulations that apply.

Minimized Risk,

How the SAFECARE System Works
1. Fresh solvent is delivered in sealed SAFECARE
containers designed to meet road, rail and sea transport
regulations.
2. Solvent is transferred to cleaning equipment with virtually
no risk of emissions or spills.
3. Used solvent is transferred from cleaning equipment to
SAFECARE recycling containers, again with minimal risk of
spills or emissions.
4. Reputable waste management firms allied with
SAFECHEM collect used solvent.
5. SAFECHEM documents waste and conducts a
comprehensive waste analysis to identify improvement
opportunities.
