Methyl Hydrogenated Rosinate
Methyl Hydrogenated Rosinate, a cosmetic-grade resin, is the methyl ester of hydrogenated gum rosin. This liquid resin undergoes a special steam-sparging treatment to ensure minimum odour and low vapour pressure, making it particularly useful as a fragrance fixative. It exhibits excellent solubility and compatibility with non-polar and many polar ingredients in cosmetic applications, contributing to both adhesion and gloss. This product serves as a substitute for Eastman® products.
It is a light amber liquid resinous tackifier and plasticizer, being hydrogenated, having marked resistance to aging. A consistent mild odor is assured after giving a special steam purification treatment. It is soluble in usual apolar organic solvents, alcohols and ethyl and butyl acetates, has a superior cold resistance ability and may maintain a valid viscosity under -40 deg C circumstance, forms a continuous film on skin, hair or nails.

Application & Uses
- Fragrance & Flavour Industry:
- Due to its low odour and low vapour pressure, it is an ideal fragrance fixative and carrier in fragrance compounds, effectively prolonging scent longevity.
- Cosmetics & Personal Care:
- Widely applied in various personal care products such as lipsticks, lip gloss, depilatory waxes, and nail polish, providing excellent adhesion and gloss, and functioning as a film-former, plasticiser, skin conditioning agent, and viscosity controlling agent.
- Adhesives & Chewing Gum Base:
- Can be used as an effective tackifier and plasticiser in the production of adhesives and chewing gum base, helping to adjust their hardness, plasticity, and chew characteristics.
- Other Industrial Applications:
- As a key resin component, it is also used in inks, floor tiles, vinyl plastics, rubber compositions, solder flux, surface active agents, and other related industrial applications.

Storage
- Environmental & Temperature Control:
- Specified Temperature Range: Store within the specific temperature range recommended on the product's Technical Data Sheet (TDS) or by the supplier, typically in a cool, dry place. Avoid extreme heat or cold to prevent polymerization or crystallization.
- Moisture Protection: Resins, especially moisture-curing types, are highly sensitive to humidity. Always store in a dry environment, away from moisture.
- Light Protection: Avoid direct sunlight and strong light exposure to prevent UV-induced polymerization or degradation.
- Good Ventilation: Ensure the storage area is well-ventilated to prevent the accumulation of harmful vapours or odours.
- Container Management & Sealing:
- Sealed Containers: Resins must be stored in their original, tightly sealed containers. Once opened, use as quickly as possible or re-seal securely to prevent air and moisture ingress.
- Inert Gas Protection: For certain oxygen-sensitive resins, it's advisable to purge the container with dry inert gas (e.g., nitrogen) before re-sealing after opening.
- Clear Labelling: Ensure all containers are clearly labelled with product name, batch number, production date, and expiry date.
- Safety & Isolation:
- Keep Away from Ignition Sources: The storage area should be away from heat, sparks, open flames, and all sources of ignition, especially for flammable resins.
- Avoid Incompatibles: Avoid co-storage with hardeners, accelerators, or other incompatible chemicals to prevent unintended reactions.
- Grounding: For flammable liquid resins, ensure equipment used for storage and transfer is earthed to prevent static build-up.
- Handling & Inspection:
- Careful Handling: Handle resins with care, avoiding vigorous shaking or tipping.
- Regular Inspection: Periodically check containers for leaks, damage, or bulging. After prolonged storage, always check the resin's quality (e.g., viscosity, appearance) before use to ensure it meets requirements.
- Compliance & Emergency Preparedness:
- Regulatory Compliance: Strictly comply with all national and local safety and environmental regulations.
- Emergency Preparedness: Have necessary emergency equipment (e.g., absorbent materials, fire extinguishers) on hand and ensure emergency plans are in place for spills, fires, etc.
