About this material
Cystine Bis-PG-Propyl Silanetriol is organosilicon amino acid derivative supplied by MakeYourSkin as clear aqueous solution with sodium citrate buffer for professional cosmetic formulation. Sourced in the China / TCM tradition. It is valued for disulphide bond support, hair strength and elasticity, nail and skin firmness.
What is Cystine Bis-PG-Propyl Silanetriol?
Cystine Bis-PG-Propyl Silanetriol is supplied under the INCI / technical name Cystine Bis-PG-Propyl Silanetriol.
It belongs to the Organosilicon amino acid derivative group. The material reaches you as clear aqueous solution with sodium citrate buffer. Pairs silanol chemistry with cystine to target the keratin disulphide network, which is the basis of bond-repair positioning. Supplied as a buffered solution; do not acidify sharply or the silanol condenses.
Key Properties & Benefits
- Disulphide bond support
- Hair strength and elasticity
- Nail and skin firmness
- Supplied with full documentation — CoA, SDS and specification
Uses & Applications
Typically formulated into bond-repair hair treatments, post-colour and post-bleach care, nail hardeners.
How to Use — Recommended Use Level
Typical use level: 1-5%. Add at the water phase. Water-soluble. Disperse into the water phase with stirring; avoid prolonged high heat where the material is heat-sensitive.
Always trial the material in your own base at small scale before scaling up. Use levels are formulation starting points, not approvals.

Regulatory Note
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.
Documentation Supplied
Certificate of Analysis (CoA) for the batch supplied; Safety Data Sheet (SDS / MSDS) in the current GHS format; INCI and technical specification sheet; allergen, GMO and origin statements on request; vegan, halal and kosher declarations where the supply chain supports them.
Available Pack Sizes

Disclaimer & Caution in Use
For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished product: do not apply it undiluted to skin or hair. Wear suitable gloves and eye protection when handling, weigh in a ventilated area, and keep out of reach of children. Patch test every finished formulation. Not for ingestion unless a food or oral-care grade is specifically supplied and documented as such. Seek medical advice in case of eye contact, ingestion or an adverse reaction. Low-pH material. Confirm the finished-product pH and provide the sun-protection and irritation warnings your market requires.

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.
