Phulwara / Chiuri Butter – Refined

RidhSa Lipids Refined Phulwara / Chiuri Butter is a purified vegetable fat recovered from the seeds of Diploknema butyracea. Following extraction, the crude fat is refined to reduce impurities, free fatty acids and natural colour or odour, depending on the chosen processing steps.

The finished butter supplies plant-derived triglycerides that contribute emollience, body and consistency to skin-care and anhydrous cosmetic formulations. It can be used in body butters, balms, creams, soap bars and customized fat blends. Refining may involve neutralization, bleaching, filtration and optional deodorization; these steps should be confirmed for each commercial grade. Physical characteristics and composition depend on origin, processing and batch, and are supplied against mutually agreed specifications.

Overview

Botanical Name Diploknema butyracea (Roxb.) H.J.Lam (syn. Aesandra butyracea; botanical identity to be confirmed for the supplied lot)
Cas# Not independently verified for refined phulwara seed fat; confirm supplier SDS, INCI designation and substance identifier.
Color Off-white to ivory or pale cream, depending on refining and grade
F.E.M.A. # Not established / not routinely applicable to refined chiuri seed fat
Cultivation Native to subtropical Himalayan foothills, particularly Nepal and parts of northern India. Ripe fruits are collected and seeds cleaned and dried before fat recovery.
Method Of Extraction Fat is recovered from dried seed kernels by mechanical pressing, traditional heat-assisted extraction or another documented process, then refined using applicable steps such as neutralization, bleaching, filtration and optional deodorization. Actual processing is grade-specific.
Constituents Triglycerides containing primarily palmitic and oleic fatty-acid residues, with stearic, linoleic and other minor fatty acids. Published profiles vary; batch GC-FAME results are required before stating exact percentages or compositional limits.
Solubility No verified universal specification; determine density of the molten butter at a stated temperature using an agreed analytical method.
Specific Gravity No universal release specification established; determine density of melted butter at a stated temperature using a validated method.
Flash Point Not routinely established for this nonvolatile vegetable fat; obtain a measured, method-specific value when required.
Optical Rotation Not routinely measured or meaningful as a release specification for refined phulwara butter.
Source Seeds of Diploknema butyracea from Himalayan regions, notably Nepal; exact collection area and origin are batch-specific.

Brief History

Phulwara or chiuri butter comes from the seeds of the Himalayan butter tree, Diploknema butyracea, traditionally associated with Nepal and adjoining Himalayan regions. Local communities have long collected its fruits and processed the seeds for household fats, lamps, soap and skin-care uses. The ingredient is now gaining interest among botanical butter and specialty-fat formulators.

Benefits

Provides emollience and skin conditioning; contributes texture and body to balms and butters; helps reduce moisture loss; refined grades generally offer lighter colour and a milder odour than unrefined material; supports customized botanical fat blends.

Uses

Body butters, lip balms, hand and foot balms, creams, soap bars, massage products, solid moisturizers, haircare and tailored cosmetic butter blends. Food use requires separately verified food-grade status and regulatory suitability.
What is refined phulwara or chiuri butter?
It is fat obtained from Diploknema butyracea seeds and subsequently purified through appropriate refining steps to improve quality and consistency.
Refining generally reduces impurities and natural colour and odour; unrefined butter retains more of its original sensory variability.
No. Deodorization is a separate step and should be confirmed from the supplier’s processing declaration.
No single melting point should be assumed for every grade. Request a batch-specific melting range or slip point measured using a stated test method.
Yes, if the supplied grade meets applicable cosmetic ingredient quality and safety requirements. Finished-product compatibility, stability and safety must also be assessed.
