RUBUS IDAEUS SEED OIL.

Valuable CAS 84929-76-0 / SKIN CONDITIONING - EMOLLIENT

Rubus Idaeus Seed Oil is a botanical lipid exceptionally rich in essential fatty acids (linoleic acid ~48-55%, alpha-linolenic acid ~28-35%, oleic acid ~12-16%), tocopherols (Vitamin E), and carotenoids (Vitamin A). It functions as a powerful emollient, antioxidant, anti-inflammatory, and antimicrobial agent, promoting skin hydration, barrier integrity, and protection against environmental stressors.

Summary

emollient antioxidant skin-conditioning moisturizing anti-inflammatory antimicrobial UV protection (adjunctive)

Science

Mechanism of Action

This oil acts on the skin primarily by reinforcing the lipid barrier through its high content of essential fatty acids. Linoleic acid is particularly critical for ceramide synthesis, which prevents transepidermal water loss (TEWL) and significantly enhances skin hydration. Its abundant antioxidants, including Vitamin E and Vitamin A precursors, effectively neutralize free radicals, mitigating oxidative stress and protecting against premature aging. Additionally, it exhibits anti-inflammatory effects to soothe irritation and possesses antimicrobial properties that can help combat acne-causing bacteria.
