Karitene dosage

Karitene is a natural carotenoid found in shea butter , known for its antioxidant, photoprotective, and nourishing properties . This fat-soluble pigment plays a key role in protecting skin cells against oxidative stress and UV damage. In the cosmetics and food , its quantification helps ensure the quality, stability, and concentration of finished products.

The assay of karitene aims to determine its content in extracts, vegetable butters or cosmetic formulations , thus guaranteeing the standardization and conformity of raw materials or finished products based on shea.

Analytical methods: HPLC and spectrophotometry

Karitene analysis is carried out using two complementary approaches:

• HPLC (high-performance liquid chromatography) : reference technique for the separation and precise quantification of carotenoids in complex lipid matrices.
• UV-Vis spectrophotometry : a rapid method for estimating the total concentration of pigments and evaluating the purity of extracts.

The choice of method depends on the matrix being analyzed , the level of precision required , and the type of product (raw or formulated). Our partner laboratories apply validated protocols that guarantee optimal reproducibility and traceability .

Industrial applications

Karitene analysis is relevant to several sectors:

• Cosmetics industry : evaluation of the antioxidant power of vegetable butters, oils or nourishing creams.
• Food processing industry : quality control of butters and vegetable fats rich in carotenoids.
• Formulation laboratories : monitoring the stability of karitene in mixtures or emulsions.
• R&D and quality control : verification of the content of natural active ingredients for shea butter-based products.

To complete this analysis, it may be relevant to measure β-carotene or other carotenoids in order to obtain a complete pigment profile.

Affected matrices

The karitene assay test can be applied to various matrices:

• Vegetable butters (especially raw or refined shea butter)
• Lipid extracts
• Cosmetic oils and topical formulations
• Dietary supplements based on plant extracts rich in carotenoids

The analysis can also be coupled with gas chromatography-MS or FTIR spectroscopy to identify other lipid markers and bioactive compounds present in the matrix.
