Which Plasticizer Makes the Softest, Longest-Lasting PVC? A Deep Dive Into DOTP, DINCH, TOTM, ATBC & DBS
A quick guide to PVC plasticizers
DOTP vs. DINCH vs. TOTM vs. ATBC vs. DBS: which makes the best inflatable?
Anyone who loves inflatables β especially for riding and playing β eventually notices something: there’s a difference between inflatables and their PVC!π
Some toys stay soft and rubbery for years, while others become sticky, stiff, or a bit brittle (we don’t like that very much…don’t we?π³) This difference almost always comes down to one ingredient:
The plasticizer. (In Dutch: weekmaker - translated roughly to: softener).
Plasticizers determine:
- how soft an inflatable feels
- how resistant the material is to cracking
- how quickly it becomes sticky over time
- how safe it is for skin or intimate use (very important, since some are toxic)
- how easily it leaks plasticizer (βoily feelβ)
- how long the inflatable will survive. I’ve used soooo much ATBC for some inflatables that they popped with a very dull ‘blof’-sound within seconds. With our famous blue pillow , inflatable itself was tough as nails to begin with so it could take more than the avarage amount!
Below is a fully detailed comparison of the five most relevant modern plasticizers for PVC inflatables:
- DOTP β the modern standard
- ATBC β a soft, natural citrate (I got experience with this one, the rest I checked onlineπ)
- DBS β extremely soft, but unstableπ¨β οΈ
- DINCH β premium, medical-grade
- TOTM β ultra-stable, long-term performer

π Best Plasticizer β Depending on What You Want
For standard inflatables:
DOTP
- great softness
- reliable lifespan
- low migration
- very affordable
Perfect for pool toys, pillows, ride-onsπ€€
For premium or professional-grade PVC:
DINCH or TOTM
They offer:
- extremely low migration
- stable softness over the years
- high skin safety
- almost no smell
- fantastic clarity
Medical-grade gear often uses DINCH; industrial high-end PVC often uses TOTM.
For maximum softness (short-term toys):
DBS
Incredibly soft and sensual at first touch.
But⦠it:
- bleeds out heavily
- becomes sticky
- hardens over time
- weakens the PVC
Not recommended for inflatables that need to last. Maybe for the poppers among us that this sparks the arousal even moreπ
For small soft items or wearable PVC:
ATBC
A natural citrate-based plasticizer thatβs very skin-friendly.
But it loses plasticizer over time and becomes stiffer.
Best for:
- thin PVC
- lingerie PVC
- sensory items
- short-lifespan products(it works for longer lasting inflas as well, but prepare for a lot of repair work!)
π Quick Summary
- DOTP = best all-around choice
- DINCH = modern premium
- TOTM = ultra-stable, professional-grade
- ATBC = soft, natural, less durable
- DBS = extremely soft but unstable
For most inflatables β especially rider-friendly ones β DOTP or DINCH propably is the sweet spot.
Final Thoughts & disclaimer
Softening would not be recommended if you are a true collector; the process could break your beloved toy if you aren’t careful. I’d recommend trying it out with a ‘dummy’ toy or let the softening be applied by an experienced looner from the communityπ
So…the right plasticizer can be the difference between:
- a soft pillow that stays supple for 10+ years
- or one that becomes sticky, oily, or cracks after just a few seasons and popping too soon.
