About this material
Pearl Protein Hydrolysate (Hydrolyzed Conchiolin Protein) is a Marine protein hydrolysate supplied by MakeYourSkin as a powder for professional cosmetic formulation. Drawn from Traditional Chinese cosmetology, it is valued for conditioning, brightening positioning.
What is Pearl Protein Hydrolysate?
Pearl Protein Hydrolysate is supplied under the INCI / technical name Hydrolyzed Conchiolin Protein.
It belongs to the Marine protein hydrolysate group and is derived from pearl / nacre protein. The material reaches you as a powder. It is an established cosmetic raw material with mature supply and well-understood formulation behaviour.
Key Properties & Benefits
- Conditioning
- Brightening positioning
- Supplied cosmetic grade with a Certificate of Analysis for every batch.
Uses & Applications
Pearl Protein Hydrolysate is used in brightening serums, spot-correcting treatments, tone-evening creams, sheet masks, after-sun products and body-brightening lotions.
Typical applications from the catalogue record: Premium masks and creams.
In leave-on skincare it is normally dosed into a serum, ampoule or moisturiser where contact time is long enough for the claim to hold up. In rinse-off formats it is used at a lower level for label presence and sensory contribution rather than measurable performance.
Handling note: Weigh accurately and dissolve or disperse fully before the batch is judged — undissolved powder reads as grit in the finished product.
How to Use — Recommended Use Level
| Typical use level | 1–5% of the supplied solution |
|---|---|
| Recommended pH | 4.0–7.0 |
| Addition phase | Water phase, cool-down |
| Solubility | Water-soluble. Disperse into the water phase with stirring; avoid prolonged high heat where the material is heat-sensitive. |
General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Technical Notes

Regulatory Note
Supplier diligence required: Species/source/allergen/animal-origin review.
Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.

Disclaimer & Caution in Use
For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished cosmetic, and it is not intended for undiluted application to skin, for ingestion, or for any medicinal purpose. Wear gloves and eye protection when handling, avoid raising dust with powders, and keep out of reach of children and pets. Always run a patch test on the finished formulation, and validate stability, compatibility, pH and preservative efficacy before sale. Information supplied is offered in good faith as formulation guidance and does not constitute a safety assessment, a regulatory approval or a medical claim.
Fine powder — avoid generating and inhaling dust. Use local exhaust ventilation or a suitable respirator when weighing, and wet the powder into the formulation phase rather than dry-blending in open air.
Animal-derived material — not suitable for vegan formulations. Confirm species, traceability, welfare documentation and any allergen labelling obligation your market imposes.
Heat-sensitive. Add at cool-down below the temperature stated on the technical data sheet; exceeding it degrades the active and can change colour and odour.

How to work with it
The specification's Add at row is the one to read first. Water-phase materials added to a hot oil phase are the most common reason a batch separates.
Measure the finished product, not the premix. Outside the range the activity drops away and, for some materials, the degradation route is what causes complaints.
Then work up through stability and compatibility testing. Higher is not better, and the destination market's limit may sit below your formulation ceiling.
