Octocrylene Cosmetic UV Absorber CAS 6197-30-4 Broad Spectrum Sunscreen Raw Material
Octocrylene is a high-purity oil-soluble broad-spectrum UV absorber with dual core advantages of UV filtration and photo-stabilization.
Different from traditional single-function UV filters that only absorb specific UV wavelengths, it integrates broad-spectrum UV protection, photo-stabilization of other filters, SPF boosting, and water resistance enhancement.
With its unique diphenylacrylate molecular structure, it efficiently absorbs UVB radiation (280-320 nm) and provides supplementary UVA coverage (320-350 nm), forming a broad protective shield against harmful solar radiation.
Meanwhile, its exceptional photo-stability ensures it does not degrade under prolonged UV exposure, and more importantly, it acts as a reliable photo-stabilizer for otherwise unstable UV filters like avobenzone (butyl methoxydibenzoylmethane), preventing their photodegradation and maintaining consistent protection throughout wear time.
In addition, it improves the texture and spreadability of sunscreen formulations, enhances water resistance, and boosts overall SPF efficiency, making it an indispensable multifunctional UV filter for modern sunscreen and daily skincare formulations.
Key Benefits
Broad-Spectrum UV Protection, Strong UVB Absorption: Professional cosmetic-grade UV absorber with high molar extinction coefficient, effectively absorbs UVB radiation (280-320 nm) and provides supplementary UVA coverage. Delivers reliable sun protection against both UVB-induced erythema and UVA-related skin damage.
Exceptional Photo-Stability, No UV Degradation: Unique molecular structure provides outstanding resistance to photodegradation. Remains stable and effective under prolonged sunlight exposure, maintaining consistent UV filtering performance throughout the product wear time.
Powerful Photo-Stabilizer for Avobenzone: Acts as a reliable photo-stabilizer for avobenzone and other UV filters prone to photodegradation. Significantly extends the efficacy duration of UVA filters and prevents formulation breakdown under UV exposure.
High SPF Boosting Efficiency: Efficiently boosts SPF values in sunscreen formulations. Small addition levels deliver significant SPF enhancement, optimizing formulation cost-effectiveness and reducing the total amount of UV filters needed.
Enhances Water Resistance: Improves the water resistance and sweat resistance of sunscreen products. Helps maintain UV protection during swimming, sports, and sweating activities, extending the effective duration of sun protection.
Excellent Oil Solubility, Easy Formulation: Freely soluble in various cosmetic oils and ester systems, easy to incorporate into oil phases. Compatible with most cosmetic raw materials, simplifying formulation development and production processes.
Mild & Low-Irritation, High Skin Safety: High-purity refined formula with low skin irritation potential. Suitable for daily sunscreen, facial care, and even sensitive skin formulations. Well-tolerated and non-sensitizing for most skin types.
Improves Formula Texture & Skin Feel: Contributes to smooth, elegant skin feel and good spreadability. Enhances the overall sensory experience of sunscreen products, reducing greasiness and improving application comfort.
Applications
Facial Sunscreen Series: Core UV filter for facial sunscreen creams, SPF moisturizers, daily UV protection lotions, and anti-aging sunscreens. Provides reliable UVB protection and photo-stabilizes other UV filters for comprehensive facial sun care.
Body Sunscreen Series: Key UV absorber for body sunscreen lotions, spray sunscreens, sunscreen oils, and all-over body sun protection products. Delivers broad-spectrum protection with excellent water resistance for daily and outdoor use.
Waterproof & Sport Sunscreens: Essential UV filter for waterproof sunscreens, sport sunscreens, swimming sun care, and sweat-resistant formulations. Enhances water resistance and maintains protection during physical activity and water exposure.
Daily Skincare with SPF: UV protective active for day creams, moisturizers with SPF, serums with sun protection, and anti-pollution skincare. Provides invisible daily UV protection without compromising texture or feel.
Color Cosmetics with Sun Protection: UV filter for BB creams, CC creams, tinted moisturizers, foundations with SPF, lip balms with sun protection, and color cosmetics. Adds sun protection to makeup products while maintaining cosmetic elegance.

Frequently Asked Questions (FAQ)
Q1: What is the MOQ of Octocrylene?
A1: The standard MOQ is 25KG. We support sample orders for formula testing, SPF evaluation, and trial production. We also offer customized specifications and packaging options for mass production requirements.
Q2: What are the core functions of Octocrylene in sunscreen cosmetics?
A2: It has four core functions: broad-spectrum UV absorption with strong UVB protection and supplementary UVA coverage; exceptional photo-stability that maintains efficacy under prolonged sun exposure; powerful photo-stabilization for avobenzone and other UV filters prone to degradation; and SPF boosting and water resistance enhancement. It is a rare multi-functional UV absorber in the cosmetic industry.
Q3: What is the recommended dosage in cosmetic formulas?
A3: Daily skincare with SPF: 1%–3%; Facial sunscreens: 3%–7%; Body sunscreens: 5%–10%; Waterproof/sport sunscreens: 7%–10%; Color cosmetics with SPF: 1%–5%. The exact dosage can be adjusted according to target SPF, formulation type, and regulatory requirements of different markets.
Q4: Is Octocrylene safe and suitable for sensitive skin and children's products?
A4: Yes. Octocrylene is a well-established UV filter with extensive safety data. It has been approved for use in cosmetics by major regulatory bodies worldwide (EU, US FDA, China NMPA). High-purity cosmetic-grade Octocrylene has low irritation potential and is suitable for sensitive skin and children's sunscreen formulations at appropriate concentrations. As with any ingredient, we recommend conducting patch testing and ensuring compliance with local regulations.
Q5: How does Octocrylene compare with other UV filters like OMC (Octyl Methoxycinnamate)?
A5: Both are UVB filters, but Octocrylene offers key advantages: significantly better photo-stability (OMC can degrade under UV exposure); ability to stabilize avobenzone and other UVA filters (OMC cannot); broader absorption spectrum extending into short UVA range; better water resistance; and higher formulation flexibility. Octocrylene is often preferred in premium and waterproof sunscreen formulations where stability and long-lasting protection are critical.
Q6: What are the formula usage notes?
A6: Oil-phase addition, heated and dissolved together with oil-phase raw materials at 60–80°C; highly compatible with other organic UV filters, physical sunscreens, and cosmetic oils; works synergistically with avobenzone to stabilize it and extend UVA protection; avoid use in highly alkaline systems (pH > 9); ensure proper emulsification in cream/lotion formulations; sealed storage to prevent oxidation and moisture absorption.
Q7: What are the best UV filter combinations with Octocrylene?
A7: Top synergistic combinations include: Octocrylene + Avobenzone (stabilizes avobenzone for full UVA protection); + Homosalate (UVB boosting); + Octyl Salicylate (UVB enhancement + solubilization); + Zinc Oxide/Titanium Dioxide (broad-spectrum hybrid protection); + Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (UVA II enhancement); + Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (broad-spectrum boost). Our technical team can provide optimized filter combinations for different SPF targets and formulation types.
Q8: Can you provide stable supply and professional technical support?
A8: We strictly control core indicators such as purity, UV absorption value, refractive index, and acid value to ensure consistent batch-to-batch stability. We support long-term bulk order supply, and provide one-stop professional services including SPF formulation optimization, UV filter combination guidance, stability testing protocols, regulatory documentation, and after-sales technical support.
