NanoActive™ Oryzanol

01 · NanoActive™ Oryzanol: Oryzanol Nanoliposomes

Cosmetic active ingredient product introduction. INCI: ORYZANOL. Rice-derived antioxidant defense, reinvented by liposomal delivery.

02 · From Rice-Bran Active to Nano-Delivered Antioxidant

γ-Oryzanol is a group of phytosterol/triterpene alcohol ferulate esters naturally found in rice bran oil. Sterol lipids provide lipid affinity, while ferulate groups provide radical-defense potential.

Antioxidant: radicals/lipid peroxidation. Photoaging care: light-induced oxidative stress. Aging care: collagen/elastic-network concepts. Skin + Hair: skin, scalp, and hair.

NanoActive™ uses lipid vesicles to improve practical cosmetic formulation design.

03 · γ-Oryzanol Ingredient Science

A mixture of ferulate esters in the unsaponifiable fraction of rice bran oil. Representative components: Cycloartenyl Ferulate, 24-Methylene Cycloartanyl Ferulate, Campesteryl Ferulate, and Sitosteryl Ferulate.

An ester bond links the phenolic antioxidant ferulic-acid moiety with a lipid-affine phytosterol/triterpene-alcohol moiety.

04 · Plant Antioxidant and Skin Lipid Science

Image: rice bran, the natural source.

01 Radical defense and oxidative-chain inhibition. 02 Lipid antioxidant activity in lipid-rich environments. 03 Ferulate UV-absorption/antioxidant properties as a basis for photostress care. 04 Research on collagenase, elastase, hyaluronidase, and tyrosinase.

05 · Multiple Antioxidant and Aging-Care Pathways

The mechanism map includes lower ROS, lipid peroxidation, oxidative damage, collagenase, elastase, hyaluronidase, and tyrosinase.

Concepts: antioxidant/photoaging care, elasticity, hydration-related structures, even tone, soothing defense, and scalp/hair antioxidants. These summarize in vitro/model literature and do not establish finished-product clinical efficacy.

06 · Radical-Chain Management and Lipid Protection

Ferulate esters participate in radical scavenging and reduced radical-induced lipid peroxidation. Relevant lipid environments include stratum-corneum lipids, sebum, cellular membranes, hair surface lipids, and oxidizable formulation oils.

Pathway: radical scavenging, lipid protection, and biological-structure protection.

07 · Oxidative Stress Connects Exposure and Skin Aging

UV/pollution/ROS, oxidative stress, cellular damage, ECM degradation, and loss of elasticity/roughness/uneven tone form the schematic pathway.

NanoActive™ Oryzanol uses antioxidant design for daily aging-care concepts. This does not replace sunscreen and provides no SPF/PA claims.

Literature nanoemulsion, H₂O₂-induced NIH/3T3 mouse fibroblast aging model: reduced intracellular ROS, supported survival/migration, and inhibition of collagenase, elastase, hyaluronidase, and tyrosinase.

Reported parameters: approximately 162 nm particle size, PDI 0.2, and zeta potential −51 mV. These are Yadav’s independent nanoemulsion values, not NanoActive™ product parameters.

09 · Protecting Collagen, Elastin, and Hyaluronic-Acid Networks

The dermal ECM schematic shows collagen, elastin, and hyaluronic acid. Oxidative stress and collagenase/elastase/hyaluronidase activity can contribute to network breakdown.

Multi-enzyme defense extends the literature concept from ROS management to structural-network preservation.

10 · Fibroblast Vitality

Dermal fibroblasts maintain collagen, elastin, and ECM. Oxidative pressure can reduce vitality/migration and accelerate structural decline.

Yadav’s 2026 nanoemulsion study reported ROS reduction, viability support, and migration in an oxidative model, informing cellular vitality, matrix defense, and resilience concepts.

12 · UV-Associated Antioxidant Defense

Schematic: UV exposure, ROS generation, lipid peroxidation, inflammatory stress, and ECM damage.

Cosmetic language: helps defend against UV-induced oxidative stress; supports daily photostress protection; helps protect skin lipids from oxidative challenge.

No SPF/PA values, sunscreen replacement, or core regulatory claim of a natural sunscreen.

13 · Nanoethosome Delivery Evidence

2021 γ-oryzanol nanoethosomes improved delivery/cellular uptake, offered long-term storage protection, and showed protection in UVB-related models.

The original mouse work involved UV-induced skin cancer; this article retains it as delivery/photostress research, without disease-prevention/treatment claims.

14 · Formulation Challenges

Low water dispersibility; crystallization/precipitation with system or temperature changes; reliance on oils, emulsions, or solubilizers; limited effective delivery of free active; and prolonged environmental exposure.

Published approaches include solubilization, dispersion, emulsification, phospholipid complexes, and nanodelivery.

Patent examples: JP6803732B2, Cosmetics containing γ-oryzanol; WO2012110303A2, Aqueous cosmetic composition containing composite material particles and gamma-oryzanol; EP1957041B1, Oil-in-water emulsion and its use for delivery of functionality.

Patent examples (publication number and title): JP6803732B2 · Cosmetics containing γ-oryzanol；WO2012110303A2 · Aqueous cosmetic composition containing composite material particles and gamma-oryzanol；EP1957041B1 · Oil-in-water emulsion and its use for delivery of functionality。

15 · From Lipophilic Active to Formulation-Ready Nano Active

Oryzanol, PURISOME® FlexVes™, and NanoActive™ Oryzanol form the design pathway.

Protection: a phospholipid microenvironment. Dispersion: an adapted form for cosmetics. Delivery: effective skin-surface contact potential. Flexibility: serums, lotions, creams, scalp, and hair products.

The design changes incorporation and contact rather than merely adding free Oryzanol.

16 · Biomimetic Lipid Vesicle Architecture

The scientific schematic labels a hydrophilic aqueous core, phospholipid hydrophilic heads, and a hydrophobic bilayer domain. Highly lipophilic γ-Oryzanol is proposed to associate preferentially with the bilayer rather than the inner aqueous core.

Oryzanol, lipid-bilayer association, vesicular dispersion, and cosmetic delivery. The localization drawing is proposed architecture rather than a direct measurement.

17 · More Than 15 Years of Liposome Research

2009 topical γ-oryzanol liposomes: phosphatidylcholine, cholesterol, CHAPS, and sodium taurocholate. Initial loading levels 3%, 5%, and 10%.

Endpoints: size, zeta potential, entrapment, release, antioxidant activity, and cellular compatibility. Antioxidant activity remained after loading; some systems showed enhanced cellular antioxidant activity.

19 · Human Evidence from Composite Rice-Bran Vesicles

Composite system: Ferulic Acid + γ-Oryzanol + Phytic Acid + Niosomes. 30 volunteers, 28 days.

Endpoints: hydration, elasticity, thickness, roughness, and pigmentation. Gels/creams containing the composite vesicles improved multiple aging-related indicators.

All human effects cannot be attributed to γ-oryzanol alone. The study supports composite rice-bran actives and vesicular delivery, not direct NanoActive™ efficacy.

21 · From Skin Lipids to Hair Lipids

Hair surface lipids face oxidative/environmental stress. Concepts: scalp antioxidant defense; hair lipid protection; sun/pollution/heat-styling care; and phospholipid conditioning support.

Patents: EP0945122A1, Haircare composition containing gamma-oryzanol and calcium salts; WO2012110303A2, skin/hair photoprotection context.

Claims stay within antioxidants, lipid care, and smoothness, excluding hair growth or hair-loss prevention.

EP0945122A1 — Haircare composition containing gamma-oryzanol and calcium salts WO2012110303A2 — relates to skin and/or hair photoprotection against ultraviolet radiation

Scalp: antioxidant serum, comfort care, post-sun care, and urban-pollution care. Hair: conditioner, mask, leave-on serum, oil/emulsion, sun-exposure care, post-color/perming care, and heat-styling care.

The source cites commercial approximately 5% γ-oryzanol emulsion ingredients for soap/facial wash, lotion, shampoo, and conditioner as market context, not this product’s active content or recommended use level.

24 · A Formulation-Friendly Oryzanol Design

Free active challenges: hydrophobicity, poor aqueous dispersion, crystallization, oil/solubilizer dependence, complex processing, restricted formats, and delivery limitations.

NanoActive™ design: lipid-vesicle organization, aqueous dispersion, handling convenience, a lipid-compatible microenvironment, serum/emulsion use, and skin/hair applications.

This is qualitative dosage-form/process comparison, without unverified fold-improvement claims. Actual performance requires formulation validation.

25 · Rice Antioxidant, Reinvented

Rice-derived science; radical/lipid-peroxidation defense; ECM protection concepts; antioxidant tone support; skin/scalp/hair use; and PURISOME® FlexVes™ liposomal delivery.
