About this ingredient
PH-40 is the standard workhorse for clear aqueous formulations that need to carry an oil phase — micellar waters, clear toners, room sprays, mouthwashes and clear shampoos. It is non-ionic, so it does not interfere with cationic or anionic systems. The usual guide is roughly three to five parts solubiliser per part of oil, adjusted by trial since fragrance oils vary widely.
Benefits
- Produces genuinely clear solutions with oils and fragrance

About PEG-40 Hydrogenated Castor Oil (PH-40)
Frequently asked
Not covered here? Send the question with your enquiry and we will answer it directly.
01 How much PEG-40 Hydrogenated Castor Oil do I need for my fragrance?
A common starting point is three to five parts solubiliser to one part oil, then adjust by trial. Fragrance oils differ considerably in how easily they solubilise, so the working ratio has to be confirmed in your own system.
02 What is the CAS number of PEG-40 Hydrogenated Castor Oil?
The CAS number is 61788-85-0 and the INCI name is PEG-40 Hydrogenated Castor Oil. It is also traded as PH-40 and HCO-40.
03 What is the difference between PEG-40 and PEG-60 hydrogenated castor oil?
The number indicates the degree of ethoxylation. PEG-60 is more hydrophilic and often preferred for surfactant systems, while PEG-40 is the more common general-purpose solubiliser for clear aqueous formulations. Both are available on enquiry.
