In-vitroResearch demonstrates that flaxseed's native cyclic peptides (linusorbs) can suppress inflammatory responses, supporting its use in cosmetic formulations to help calm and soothe the appearance of sensitized or irritated skin.
Linum Usitatissimum Seed Extract
Formulate Labs’ Linum Usitatissimum Seed Extract, provided in a standard or concentrated hydroglycerin stock, is a multifunctional botanical active driven by cyclic peptides (linusorbs), alpha-linolenic acid, and mucilage polysaccharides, enabling formulators to create products with benefits similar to well-known trade-name materials using the pure INCI.
Botanical source of linusorbs and mucilage polysaccharides.
Botanical Identity: Linum Usitatissimum Seed Extract, commonly known as Flaxseed Extract, is a botanical powerhouse. Trade Names & Context: While known in various forms such as Linum usitatissimum seed powder, linseed, or flax gel powder, Formulate Labs offers the pure INCI active, enabling formulators to integrate its benefits without proprietary supplier SKUs.
Dual mechanism: Upon application, the mucilage fraction of Linum Usitatissimum Seed Extract forms a breathable, non-occlusive hydrogel film on the stratum corneum, effectively limiting transepidermal water loss (TEWL) to maintain skin hydration. Simultaneously, the extract's linusorb peptides provide antioxidant activity by neutralizing reactive oxygen species and inhibit key pathways in melanin synthesis, making it suitable for cosmetic systems targeting mature, sensitive, or hyperpigmented skin.
Use levels: For daily care products such as serums, lotions, and creams, a typical use rate of Formulate Labs' Standard or Concentrated hydroglycerin stock is 2.0% to 5.0%. For intensive treatments like masks and scalp care applications, this stock can be incorporated at up to 10.0%.
Market context: The functional cyclic peptides, polysaccharides, and lipids present in Linum Usitatissimum Seed Extract are the scientific foundation for several prominent trade-name materials. Formulate Labs offers the pure INCI active, enabling formulators to develop products with comparable functional benefits to Sculptessence™-class actives (for combating skin sagging and deep hydration), Linodermine™-class actives (for calming sensitive skin), and FSS Flax Seed Extract G PET-class actives (for deep hydration and anti-inflammatory appearance benefits).
We ship standard or concentrated extract stock with selectable preservation - ready to meter into finished formulas at the use rates in the formulation guide below.*
Formulate Labs provides the pure INCI active, enabling formulators to achieve similar functional benefits found in other trade-name materials (e.g., Sculptessence™, Linodermine™, FSS Flax Seed Extract G PET).
Every lot is produced to order in our AI-powered robotic factory. Nothing sits on a warehouse shelf going stale - you get a date-of-manufacture-fresh batch every time.

Formulate Labs' <em>Linum Usitatissimum</em> Seed Extract is backed by compelling scientific research demonstrating its efficacy. Studies highlight the ability of its native cyclic peptides (linusorbs) to suppress inflammatory responses, inhibit melanin synthesis, and maintain structural stability through processing, affirming its multifunctional cosmetic benefits for soothing, brightening, and protecting skin. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
Research demonstrates that flaxseed's native cyclic peptides (linusorbs) can suppress inflammatory responses, supporting its use in cosmetic formulations to help calm and soothe the appearance of sensitized or irritated skin.
This study identifies unique peptide markers in flaxseed resilient to heat, highlighting the structural stability of its functional proteins. This thermal stability ensures active components maintain integrity and cosmetic function through typical formulation manufacturing cycles.
Linusorbs from flaxseed strongly inhibit tyrosinase activity and downregulate MITF, suppressing melanin synthesis by up to 90% without cytotoxicity, providing a strong basis for brightening and even skin tone treatments.

Bulk composition at the selected Linum Usitatissimum Seed Extract loading. Base carrier components scale proportionally when preservative is added; extract stays at the selected loading. Updates dynamically when you change base or preservation above. Full CAS disclosure is on the SDS/TDS for the selected variant (FL-LUS-W2-MBS4-5PCT-001).
SDS + TDS are issued per selected recipe. Links swap when you change selections above. A sample COA shows the standard extract QC panel (pH, organoleptic, TAMC/TYMC). Lot-specific COAs ship with every order.
We cook the raw botanical powder into the selected carrier. The botanical carries polar phenolics, flavonoid glycosides, and related extractable fractions. Those markers support antioxidant and skin-conditioning cosmetic stories. This is not a solvent isolate or a standardized marker extract. Lot identity appears on the COA and TDS.
This is a ready-to-use cosmetic extract stock, not a finished consumer product and not a standardized marker isolate. We cook the raw botanical powder into the selected hydroglycerin or oil carrier. Aqueous lots are released on pH, organoleptic, TAMC, and TYMC (total counts only). Oil macerates are released on organoleptic only. A sample COA is on this page; the lot-specific COA ships with the order.
