PEG-40 Hydrogenated Castor Oil (Low Color)
Pharcos HCO 40 C
Also known as: Deodorized PEG-40 Hydrogenated Castor Oil | Low-Odor Solubilizer
Pharcos HCO 40 C represents the highest cosmetic purity available. Standard PEG-40 HCO often carries a slightly yellowish tint and a very faint, characteristic fatty scent. This 'C' (Clear/Colorless) grade undergoes an intense secondary stripping process to remove all trace color bodies and volatile odor compounds. It is strictly designated for high-end luxury cosmetics, 'water-clear' facial serums, and premium alcohol-free perfumes where visual and olfactory neutrality is non-negotiable.

How It Works
The solubilization mechanics are identical to standard HCO 40 (micellar entrapment via HLB ~14-16).
However, in premium perfumery, even trace amounts of naturally occurring aldehydes or ketones left over from the ethoxylation process can chemically interact with delicate fragrance notes (especially citrus or floral top notes), skewing the scent profile. The profound lack of these reactive impurities in the 'C' grade ensures the absolute fidelity and longevity of the formulated fragrance.
Technical Information
Common questions about PEG-40 Hydrogenated Castor Oil (Low Color)
No, standard HCO 40 is perfectly adequate for 95% of shampoos, body washes, and lotions, as dyes and pearlizing agents mask the slight yellow tint natively. The 'C' grade is strictly for products marketed as 'Crystal Clear' or high-end fine fragrances.
