Warm Evening Fragrance Oil, 500 ml

Warm evening fragrance oil adds fragrance to cosmetics, soaps, candles and household products. It is a synthetic fragrance composition of cosmetic grade and European origin, and in a formulation it has a single role: to scent the product. It is mixed into the finished base at the end of production at a temperature below 40 °C, with no further preparation.

The composition withstands acidic, neutral and alkaline environments, all common types of surfactants, and alcohol. You can therefore carry the same fragrance into a shampoo, a soap bar, a bath bomb, a deodorant or a hydroalcoholic perfume. It is suitable for rinse-off and leave-on products, including facial and children’s cosmetics, always within the IFRA limit for the given category.

Key properties

• Wide compatibility – anionic, cationic, non-ionic and amphoteric surfactants, alcohol and the whole pH range from acidic to alkaline. When choosing a surfactant blend or a soap base, you do not need to check whether it will be compatible with the fragrance.
• Oil solubility – it is mixed directly into the oil phase, butters and anhydrous products. It does not dissolve in water, so purely water-based systems need a solubiliser.
• Low-temperature processing – it is added during the cooling phase or afterwards, when the batch is below 40 °C.
• Rinse-off and leave-on products – from shower gels and body milks to facial creams and lip products, according to the IFRA definitions for the individual categories.
• No materials of animal origin – the composition is paraben-free, is not produced using GMOs and has not been tested on animals.

Use in a formulation

In emulsions, the fragrance oil is added only after the finished cream or milk has cooled below 40 °C, while stirring constantly. It does not belong in the oil phase before heating. For body butters, balms and massage oils, it is enough to mix it into the oil or into a mixture that is beginning to set. In shampoos, shower gels and liquid soaps, it is mixed directly into the finished surfactant blend. For clear products, check that the base stays clear.

Toners, air fresheners and other products without an oil phase need a solubiliser, for example Polysorbate 20. The fragrance oil is first mixed with the solubiliser and only then added to the water phase. The ratio is adjusted on a trial sample and depends on both the fragrance usage rate and the chosen solubiliser.

Soap bars, liquid soaps, bath bombs and bath salts are among the listed uses. Its behaviour in cold process soap (faster trace, colour change of the mass) has not yet been verified by a practical test, so we recommend a small trial batch first. For bath salts and bath bombs, the oil is mixed with the oil component before it is combined with the dry mixture.

Candles are a separate category, IFRA 12. The fragrance oil is added to the melted wax before pouring, and the usage rate is kept within the limit for this category. A trial candle shows how well the wax holds the fragrance and how the wick burns. The same composition can also be used in diffusers, household cleaning products and dishwashing products.

Suitable for products such as

• soap bars and liquid soaps, shampoos, shower gels and conditioners
• body creams, milks, butters and massage oils
• facial creams, toners, decorative cosmetics and lip products within the IFRA limits
• deodorants, antiperspirants and intimate hygiene products
• hydroalcoholic and oil-based perfumes
• bath bombs and bath salts
• candles of all types, including container candles
• diffusers, air fresheners, cleaning products and dishwashing products

Good to know

The fragrance in the bottle and the fragrance in the finished product differ. Surfactants, soap base and wax all shift it, so its character is judged only on the finished product: for soap after curing, for a candle after a trial burn.

Fragrance oil is a synthetic composition and differs from an essential oil. It adds fragrance and no aromatherapeutic or skin-care effects are attributed to it. In diffusers and aroma lamps, it is used purely to scent a room.

The composition contains fragrance allergens listed in Annex III of Regulation (EC) No 1223/2009, as amended by Regulation (EU) 2023/1545. For a cosmetic product, they are therefore taken into account in the ingredient list. The product as a whole is not classified as CMR, but it contains one or more components with such a classification. Their list is in the parameters and in the safety data sheet.
