CO₂-to extract from raspberry seeds BIO is a thick fatty oil obtained by supercritical extraction with carbon dioxide from dried raspberry seeds (Rubus idaeus) from certified organic cultivation. Supercritical CO₂ extraction is carried out without organic solvents and under gentle temperature conditions. The result is a full-spectrum lipophilic extract that preserves the complex lipid spectrum of the seed, including fatty acids, the tocopherol fraction and other naturally occurring lipophilic components.
For the production of 1 kg of extract, 6.0–8.0 kg of raspberry seeds are processed. The result is a yellow-brown oil with an exceptionally high content of polyunsaturated fatty acids. The extract contains 48–63% linoleic acid (omega-6, C18:2) and 23–30% alpha-linolenic acid (omega-3, C18:3), with the PUFA fraction accounting for a total of 82.5% of the total fat content. For better oxidative stability, the extract is conventionally stabilized with 0.1% BIO rosemary antioxidant extract.
The extract is lipophilic — it is not soluble in water and is included in the oil phase. It is compatible with vegetable oils, natural and synthetic esters, waxes and silicones. In emulsions, it can be incorporated into the oil phase or into the cooling phase, depending on the type of formula and technological procedure.
To preserve the integrity of the PUFA fraction, we recommend adding it during the cooling phase, ideally at a temperature below 40 °C. The high content of polyunsaturated fatty acids makes the extract more sensitive to oxidation, therefore, in formulations with a longer intended shelf life it is appropriate to combine it with another antioxidant, for example tocopherol or rosemary extract.
The yellow-brown hue and natural seed aromatic profile may affect the colour and scent of light formulations. In white emulsions, transparent oil gels or delicately perfumed products, we recommend testing in a small development batch.
The product is intended for cosmetic use only. We recommend using it as part of a formulation, not as a separate undiluted product without prior compatibility testing. The extract is sensitive to oxidation caused by heat, light and atmospheric oxygen — store it in well-closed containers, ideally with as little air in the packaging as possible. To maximally preserve the fatty acid profile, it is advisable to store it under an inert gas, such as nitrogen or argon. Store in a cool, dark and dry place, away from sources of heat and out of the reach of children. More detailed information on the quality of a specific batch can be found in the certificate of analysis, which we update for each new batch of the product.
Cold pressing obtains the oil by mechanical pressure. Supercritical CO₂ extraction works without organic solvents and under gentle temperature conditions, which makes it possible to obtain a complex lipophilic extract from the seed. Both methods provide an oil-like raw material with a high content of unsaturated fatty acids, but the CO₂ extract is usually more precisely analytically characterized according to the specific batch.
A high content of PUFA, i.e. polyunsaturated fatty acids, contributes to a lighter sensory profile and is interesting for the development of modern oil serums, creams and regenerative emulsions. At the same time, however, it means higher oxidative sensitivity. Unsaturated bonds react with oxygen, heat and light, therefore antioxidant protection, suitable packaging and stability testing of the finished product are important.
Rosemary extract is added in a low amount as an antioxidant stabilizer of the raw material. It helps protect sensitive unsaturated fatty acids from oxidation during storage. When compiling the INCI list of the finished cosmetic product, we recommend basing it on the current documentation for the raw material and on the overall composition of the final formula.
Yes, the combination is possible, but the overall PUFA profile of the oil phase must be monitored. If you combine several oils rich in omega-3 fatty acids, the oxidative sensitivity of the mixture may increase. In such formulas it is advisable to use sufficient antioxidant protection, minimize contact with air during filling and verify the stability of the product during storage.
Yes, the extract has a yellow-brown hue that can be transferred into the finished product, especially at higher concentrations and in white or transparent formulations. For light creams, gels or gently tinted serums we recommend preparing a test batch. In oil formulations, balms or products with a naturally earthy tone, the colour usually does not present a problem.
Yes, the lighter PUFA profile is also suitable for leave-in hair oils, serum bases and treatments for dry or damaged hair. It is included in the lipophilic part of the formulation in the same way as in facial cosmetics. However, it must be taken into account that the natural colour and scent of the extract may affect the character of the finished product.
