X50 Pure White

A delivery system rather than a single peptide

X50 Pure White is a commercial brightening complex, so its label reads more like a short recipe than one INCI name. The published system pairs a lactic acid and glycolic acid copolymer with polyvinyl alcohol, which form the carrier, and two long-named palmitoyl peptide amides that make up the active part. That is why the INCI is long. CAS is Mixture.

Where it sits among tone actives

This page is X50 Pure White. X IGHTENING powder, the X50 Lightening complex, is a separate X50-family listing with arbutin and sodium ascorbyl phosphate in its system. Nonapeptide-1 is a different single brightening peptide. Do not merge their CoAs or labels. Other tone peptides are in our peptide solutions.

Formulating with it

Phase and temperature

Add it in cool-down, below 40 °C, with gentle mixing, and avoid long holds at high temperature. Add it to the water phase of serums and gels, or to a finished emulsion once it has cooled. Gentle mixing protects the carrier particles.

Compatibility

Keep it away from strong oxidizers and very salt-rich bases, and check clarity and viscosity after it goes in.

Level

Take the use level from the supplier documentation for your lot.

Product types that suit it

Brightening serums, even-tone essences, spot-look correctors, light day creams and sheet-mask liquids.

Pairing ideas

Niacinamide, stable vitamin C derivatives, sodium hyaluronate and glycerin. Add each active separately and check clarity, odor and viscosity after each addition instead of premixing several actives in one beaker.

Example architecture

The level comes from the CoA, so no gram recipe is shown here.

Claims

Describe skin that looks brighter, clearer and more even in tone with regular use. Keep claims cosmetic and tied to appearance. Any before-and-after statement needs a test on the finished product, not on the raw material.

Testing the finished product

Run a stability check on the finished product at room temperature, at 40 °C and in a fridge for several weeks, and watch color, odor, clarity, viscosity and pH. Check the product in its final pack too, since pumps, droppers and jars expose it to air differently. A preservative challenge test on the final product is the standard step before launch.

Lot handling and storage

Record appearance and pH on arrival, compare them with the CoA, and keep the CoA with your batch records so each finished batch can be traced to its lot. Store tightly closed, cool and away from light, and respect the shelf life on the CoA.

Labeling and documents

Write the INCI exactly as the CoA for your lot gives it, in the order the supplier lists it, and keep the CAS line the same as the CoA, including N/A or Mixture where that is what it says. Keep the CoA with your batch records. If your market needs an SDS or a full ingredient breakdown, ask for it before you scale so the paperwork matches the batch you buy.

Ordering

It is sold as a raw material for cosmetic formulation, not as a finished consumer product. Start with a small pack for bench trials and scale once your stability checks pass. It ships from Florida, usually within 1 to 2 business days, in the pack sizes shown above, and US shipping is free on orders of $50 or more.
