See our full sample process →Milk Thistle Seed Butylene Glycol Extract is a liquid preparation of Silybum marianum seed presented in butylene glycol, a water-compatible humectant carrier widely used in personal care. It is supplied full-spectrum and non-standardized. Bio-Botanica produces this cosmetic-grade liquid for product developers building leave-on and rinse-off skincare.
Cognitive Market Research places the milk thistle extracts market on a growth path of about 6.00% CAGR between 2023 and 2030, and botanical seed actives in glycol carriers remain a familiar building block for clean-beauty launches. Cosmetic chemists increasingly seek recognizable plant extracts compatible with water-phase formulas.
The butylene glycol carrier makes this seed extract convenient for water-phase blending in serums, toners, essences, hydrating mists, and moisturizers. Because the carrier is glycol rather than oil, it suits aqueous systems and sheet-mask serums. Brands can position it as a botanical seed active within Mediterranean-inspired facial-care collections.
Since 1972 Bio-Botanica has extracted botanicals at its Hauppauge, New York cGMP site, and this seed liquid is made with the proprietary Bio-Chelated low-heat process to preserve a Holistically Balanced profile.
