Information about Sea Kelp Bioferment and Lanolin

Based on your questions about Sea Kelp Bioferment and Lanolin:

• Sea Kelp Bioferment: The Sea Kelp Bioferment sold by the company contains a preservative, specifically Phenoxyethanol at 0.3%. While you can mix other ingredients into it, it is not recommended to use it as a primary cream base in high concentrations (above 10-30%). It is best used at a concentration of 10-30% within a water-based formulation, possibly with a gelling agent to create a gel texture, rather than a standalone base for a cream.

• Lanolin Natural / Synthetic Lanolin: Natural Lanolin (Sheep Wool Grease, Anhydrous, Deodorized), Synthetic Lanolin (Lanofree™), and LipidSoft™ Lanolin are emollients used in the oil phase of formulations. Their product descriptions do not indicate that they contain added preservatives themselves. However, if you use them in a formulation that contains water (like a cream or lotion), you must add a suitable preservative system to the final product to prevent microbial growth.

• Using as a Cream Base and Mixing: Neither Sea Kelp Bioferment nor Lanolin (or its alternatives) are suitable to be used as a simple standalone cream base by just adding one other natural extract. Sea Kelp Bioferment is a water-based active ingredient. Lanolin and its alternatives are oil-based ingredients. To combine water-based and oil-based ingredients into a stable cream, you need a proper formulation that includes an emulsifier to bind the water and oil phases together, along with a preservative system (as mentioned above, especially if water is present).

Therefore, simply mixing Sea Kelp Bioferment, Lanolin/alternative, and one other natural extract will likely not result in a stable cream base suitable for moisturizing, anti-aging, and skin strengthening. A complete cream formulation requires multiple components to create a stable and effective product.
