Toxicity Summary · 2 件

Based on available data, the CIR Expert Panel concluded that ... t-Butyl Methacrylate is safe as used in nail enhancement products when skin contact is avoided. Products containing these ingredients should be accompanied with directions to avoid skin contact, because of the sensitizing potential of Methacrylates.

Safe for use in cosmetics, with qualifications

説明Tert-butyl methacrylate (TBMA) is an ester of Methacrylic acid used as a raw material component in synthesising polymers. TBMA is a functional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic hydrophobic group. Copolymers of tert-Butyl Methacrylate (TBMA) can be prepared with (meth)acrylic acid and its salts, amides, and esters, as well as with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils, etc. It can be used in emulsion polymerization similar to other well-known acrylates like Butyl Methacrylate or Methylmethacrylate. It is a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds. It imparts chemical resistance, adhesion, hydrophobicity, hardness, scratch resistance, heat resistance, high solids, and weatherability to polymers.

使用tert-Butyl methacrylate (tert-BMA) can be used in the formation of homo and block copolymers by atom transfer radical polymerization (ATRP) for potential usage in coatings, biomaterials and flocculants.

一般的な説明A colorless liquid with an ester like odor. Flash point below 141°F. Less dense than water and insoluble in water.
