Ingredient Substitution and Preservatives

Thank you for your question. To help you find a suitable replacement, please specify which ingredient from your list is unavailable.

Regarding your question about replacing deionized water with rose water and omitting preservatives, it is important to understand the role of preservatives in cosmetic formulations.

Preservatives are crucial for preventing the growth of bacteria, mold, and yeast in water-based products. Without a preservative, these microorganisms can contaminate the product, leading to spoilage, reduced effectiveness, and potential harm to the skin.

While rose water (such as Rose Water (Rosa Damascena) or Bulgarian Rose Water) can be used as part of the water phase in your formulation, it is still a water-based ingredient and does not provide sufficient preservation on its own. Therefore, even if you use rose water instead of plain deionized water, you will still need to include a suitable preservative to ensure the safety and stability of your product.

Common preservatives used in cosmetics include Phenoxyethanol and Sodium Benzoate. Imidazolidinyl Urea is also a type of preservative.

Ingredients like Glycerin, Niacinamide, Acetyl Glucosamine, Butylene Glycol, Aloe Vera Extract, Allantoin, Trehalose, and Centella Asiatica Extract are beneficial for the skin but do not act as preservatives.
