Bisoctrizole (Methylene Bis-Benzotriazolyl Tetramethylbutylphenol) is a Particulate broad-spectrum UV filter supplied by MakeYourSkin as powder / oil / dispersion depending filter for professional cosmetic formulation. Used worldwide across mainstream cosmetic formulation, it is valued for uv absorption / scattering.

What is Bisoctrizole?

Bisoctrizole is supplied under the INCI / technical name Methylene Bis-Benzotriazolyl Tetramethylbutylphenol and carries CAS number 103597-45-1.

It belongs to the Particulate broad-spectrum UV filter group and is derived from global. The material reaches you as powder / oil / dispersion depending filter. It is an established cosmetic raw material with mature supply and well-understood formulation behaviour.

Key Properties & Benefits

• UV absorption / scattering
• Contributes measured UV attenuation; SPF and UVA performance must be tested on the finished formulation.

Uses & Applications

Bisoctrizole is used in sunscreens, SPF moisturisers, SPF makeup, after-sun and UV-protective hair products.

Typical applications from the catalogue record: Sunscreens, SPF makeup, UV-protective products.

Sun-care work starts from the permitted filter list for the destination market, then builds the SPF and UVA-PF by in-vitro screening before in-vivo confirmation.

Handling note: Add to the oil phase and protect from prolonged heat and air exposure.

How to Use — Recommended Use Level

General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Technical Specification

Regulatory Note

UV filters are among the most tightly controlled cosmetic ingredients. Permitted filters, maximum concentrations, nano status and labelling differ substantially between the EU, the United States, India, Japan, Korea and China. In the United States sunscreens are regulated as OTC drugs. Never assume a filter permitted in one market may be used in another, and confirm the current positive-list entry before formulating.

Supplier diligence required: Highly jurisdiction-specific: permitted filters, concentration limits, nano labeling and drug/cosmetic classification must be checked.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.

Disclaimer & Caution in Use

For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished cosmetic, and it is not intended for undiluted application to skin, for ingestion, or for any medicinal purpose. Wear gloves and eye protection when handling, avoid raising dust with powders, and keep out of reach of children and pets. Always run a patch test on the finished formulation, and validate stability, compatibility, pH and preservative efficacy before sale. Information supplied is offered in good faith as formulation guidance and does not constitute a safety assessment, a regulatory approval or a medical claim.

Fine powder — avoid generating and inhaling dust. Use local exhaust ventilation or a suitable respirator when weighing, and wet the powder into the formulation phase rather than dry-blending in open air.

Regulated UV filter. Permitted filters and maxima differ by market and in the United States sunscreens are drugs. SPF and UVA claims must be supported by testing on the finished formulation, not by the filter's specification.

May be supplied in a nano grade. Confirm particle size and the regulatory nano status of the exact grade, observe format restrictions where inhalation exposure is possible, and apply '[nano]' labelling where required.

Restricted or high-diligence material. Confirm your legal position in every destination market before ordering. Supplied on the understanding that the buyer holds responsibility for compliant use, permitted concentration and claim wording.
