A Citrus-Based Ingredient Valued for Balancing Oily and Combination Skin
Grapefruit fruit extract in a 100 ml bottle is a concentrated plant-derived ingredient obtained from the pulp and juice of the fruit, prized for its natural acids, flavonoids and vitamin C content. Its main application lies in skincare formulations for face and body care: toners, serums, creams for oily and blemish-prone skin, spot treatments, and refreshing body products. Beyond skincare, this extract is also used in citrus-forward perfumery compositions and in select household chemical formulas that call for a natural antioxidant note. The product belongs to the Liquid Extracts section, which brings together water-alcohol-glycerin extracts suited for a wide range of formulations.
Grapefruit extract performs particularly well in formulas targeting oily and combination skin thanks to its astringent and mattifying properties, and it is frequently included in products designed to address enlarged pores and localized breakouts. In leave-on and rinse-off skincare, it is added to the water phase during the cooling stage, at temperatures not exceeding 40 degrees, which helps preserve the activity of its natural compounds. Recommended dosage for creams, lotions and toners ranges from 1 to 5 percent of the total formula weight, while serums can accommodate concentrations up to 7-8 percent provided a preliminary compatibility test is performed. In shampoos and products for oily scalp, the extract is typically used at 1-3 percent, contributing a sense of freshness to the scalp.
This ingredient combines well with other botanical extracts, allowing formulators to build multifunctional complexes. Paired with Apple Fruit Extract, it creates a gentle toning blend suitable for daytime care, while combining it with Hemp Extract is common in calming formulations for sensitive, irritation-prone skin. For warming or stimulating scalp treatments, a small proportion of Hot Pepper Extract is sometimes added alongside grapefruit to encourage mild circulation and support hair follicle activity.
The 100 ml size is intended primarily for home-based cosmetic making, formula testing, and small trial batches before scaling up to larger production runs. This volume suits formulators who prepare custom blends for individual clients or who are experimenting with active ingredient concentrations before committing to bigger volumes. The extract should be stored in a tightly sealed container, kept in a cool, dark place away from direct sunlight and heat sources, which helps maintain the stability of the formula throughout its shelf life.
