Shelf life and stability of royal jelly in cream/gel formulations
Question
What is the shelf life of a cream or gel formulation containing royal jelly? Does the form of royal jelly used (powdered vs. fresh) affect the shelf life of the finished product, especially when a preservative is included? How should the powdered Royal Jelly Extract 10-hydroxydecanoic acid (98% Purity) be stored before use?
Answer
Shelf Life of Royal Jelly in Cream/Gel Formulations
Regarding your questions about using royal jelly in cream or gel formulations:
Shelf life in cream/gel with preservative: When royal jelly extract is incorporated into a cream or gel formulation and a proper preservative system is included, the shelf life of the finished product typically depends on the overall stability of the formulation and the effectiveness of the preservative. A well-formulated and properly preserved cosmetic product can often have a shelf life of 1 to 3 years, similar to other cosmetic creams or gels. The key is ensuring the preservative system is effective against potential microbial growth in the specific formula.
Powdered vs. Fresh Royal Jelly Stability: In its raw form, powdered royal jelly is generally more stable than fresh royal jelly because the lack of water inhibits microbial growth. However, once either form is mixed into a water-based formulation like a cream or gel, the stability and shelf life of the finished product are primarily determined by the effectiveness of the preservative system and the overall formulation's stability, not whether the royal jelly was originally powder or fresh. Both forms require adequate preservation in a water-containing product.
The Royal Jelly Extract 10-hydroxydecanoic acid (98% Purity) product you purchased is a powder form. For long-term storage of this raw material before use, it should be kept in the refrigerator (5°-8°C), away from direct sunlight and heat, with the lid tightly sealed. Once incorporated into your formulation, follow good manufacturing practices and ensure your preservative system is robust.
