Personal care
Yes, fragrance oils can be used in soap and body products when the specific fragrance is suitable for that application and used within the relevant safety limit. Do not assume every fragrance is suitable for every body product. Check the IFRA documentation for the finished product category, review allergen and regulatory requirements, then run stability and performance testing in the actual formulation.
Personal care
The maximum safe fragrance level depends on the finished product category and the fragrance formula. Check the supplier's current IFRA conformity information for the exact application, then make sure your finished product stays at or below that maximum. The limit is not a recommendation for how much fragrance you should use. Your practical level may be much lower once skin feel, stability, odour and product performance are considered.
Personal care
Some fragrance materials can speed up trace in cold process soap, while others can affect colour. Vanillin is a common cause of brown or tan discolouration, and certain floral or spicy materials can accelerate the soap reaction. Always test a small batch before production. If a fragrance is known to accelerate, prepare your colours and moulds first and work with a process that gives you less unnecessary mixing time.
Personal care
Yes, suitable fragrance oils can be used in lotion, body wash and shampoo, but the permitted level and formulation behaviour can differ between products. Check the relevant IFRA category for each finished application, then test solubility, viscosity, colour, odour and long term stability. A fragrance that works in a rinse off wash may not behave the same way in a leave on lotion.
Personal care
Cosmetic safe fragrance is a practical description, not a guarantee that one oil can be used at any level in every cosmetic. A candle only fragrance may have no suitable use level for the cosmetic application you have in mind, or it may simply not have been developed for that use. Always rely on the current IFRA documentation for the actual finished product category rather than a broad marketing label.
Personal care
Start with the supplier's allergen information and the current regulatory rules for the markets where you will sell. Fragrance allergens may need to be declared when they are present above specified thresholds in certain cosmetic products. The exact obligation depends on the product and jurisdiction. Keep the fragrance documentation linked to the batch you purchase so you can update labels if the formula or rules change.
