JY-P254-4 Diphenyl Silicone Oil is presented by Juyou as a high-phenyl-content diphenyl silicone oil for personal care formulation work. For B2B buyers, the practical purchasing record should separate appearance, refractive index, viscosity, flash point and volatile-matter checks from broader claims about finished-formula performance.
The current product source lists INCI as Diphenyl Dimethicone, appearance as colorless transparent liquid, density as 1.06-1.07 g/cm3, viscosity at 25 C as 390-500 mm2/s, refractive index at 25 C as 1.495-1.515, open-cup flash point as at least 300 C, and volatiles at 5 g, 2 h and 250 C as below 1.0 percent. These are source-page checkpoints that should be matched to the offered lot COA before purchase.
Keep volatile-matter and heat records separate
JY-P254-4 is described for sunscreen creams, skin care lotions, lipsticks, lip glosses, color cosmetics, hair conditioners and related personal care applications. Before approving a sample, ask Juyou for the product source, latest TDS, MSDS, applicable lot COA, lot number, package option and storage statement. The buyer should then run its own formula trial for clarity, odor, compatibility, gloss, film feel and heat exposure.
The source page says the grade has high refractive index, high gloss, heat resistance, radiation resistance and water repellency. Treat those as screening directions, not guaranteed results in every cosmetic system. If the intended use involves elevated temperature, pigment dispersion or anhydrous oil phases, record the process temperature, hold time, observation period and any required volatile-matter limit in the RFQ.
Fields to keep in the purchasing file
- Identity: product code, INCI name, source page, TDS, MSDS, COA, lot number and quotation revision.
- Lot checks: appearance, density, viscosity at 25 C, refractive index at 25 C, flash point and volatile-matter record.
- Formula scope: cosmetic category, oil phase, pigment or UV-filter load, heat exposure and observation period.
- Commercial record: package option, destination, sample quantity, annual volume and required document list.

Frequently Asked Questions
Which JY-P254-4 records should be checked first?
Start with appearance, density, viscosity at 25 C, refractive index at 25 C, open-cup flash point, volatile-matter record, TDS, MSDS and COA.
Why separate volatile-matter and heat records?
They answer different purchasing risks. Volatile matter helps screen lot consistency, while process heat still needs a formula-specific stability trial.
Which applications are listed for JY-P254-4?
The source page lists sunscreen creams, skin care lotions, lipsticks, lip glosses, color cosmetics, hair conditioners and other personal care uses.
What should the RFQ include?
Include product type, process temperature, volatile-matter requirement, compatibility concern, sample demand, destination, annual volume and required TDS, MSDS and COA documents.
