Trade Name: YOBISOL PINK 5BLG · CI Number: Solvent Red 127
Solvent Red 127 is a bright bluish-pink to red solvent dye popular in wax and candle colouring, plastics tinting, and specialty ink formulations. Its good solubility in alcohols and esters makes it easy to incorporate into a wide range of solvent-based systems. Supplied by Yobai Industries as YOBISOL PINK 5BLG.
In candle and wax colouring, YOBISOL PINK 5BLG dissolves cleanly in the paraffin or soy wax melt and distributes evenly through the cast. The bluish-pink character — positioned between a true red and a cool cosmetic pink — is distinctive in opaque and semi-transparent wax where flat, uncomplicated colour is preferred. In plastics and cosmetic packaging, it gives transparent rose tints at low loading and deep pink at higher concentration in polystyrene and acrylic. Its compatibility with alcohols and esters suits flexographic and gravure inks for beauty and personal-care product packaging. Verify final shade in your specific substrate and resin system before committing to a production run.

Polar solvents (alcohols, esters) give highest solubility for SR127. Batch-specific TDS available on request.
Solvent Red 127 dissolves most readily in polar solvents — alcohols and esters give the fastest and cleanest dissolution. Unlike mineral oil-based solvent dyes, its performance in straight aliphatic petroleum products is limited. For wax and candle applications, pre-dissolving in a small quantity of ethanol or fragrance oil before adding to the paraffin melt is the recommended approach for even, streak-free incorporation.
For transparent plastic colouring, pre-dissolve in a concentrated masterbatch carrier at 0.5–2% strength before let-down. This gives uniform colour distribution in the moulded part. For gravure and flexo inks, good compatibility with ester-based and aromatic carrier systems. The bluish-pink shade develops cleanly in transparent resin without the green shift seen in some yellow-pink types.
Starting-point guidelines — actual loading depends on shade depth required, substrate type, and process conditions. Trial at lab scale before committing to production.
| Application | Loading (%wt) | Solvent System | Processing Temp | Notes |
|---|---|---|---|---|
| Candle / Wax | 0.01–0.20% | Paraffin / soy melt | 70–80°C | Pre-dissolve in ethanol for best dispersion |
| Plastics (PS / Acrylic) | 0.05–0.3% | Carrier masterbatch | 160–180°C | Transparent bluish-pink — verify migration in substrate |
| Printing Inks | 0.5–3.0% | Esters / aromatic solvents | Ambient | Good in ester-based flexo and gravure systems |
| Coatings / Lacquers | 0.1–0.5% | Alcohols / esters | Ambient | Pre-dissolve; filter before adding to binder |
| Cosmetic Packaging (PS / Acrylic) | 0.05–0.2% | Masterbatch moulding | 160–180°C | Cool blue-pink suitable for skincare and beauty pack |
