  2. Thiomalic acid - Wikipedia

    en.wikipedia.org/wiki/Thiomalic_acid

    Thiomalic acid or mercaptosuccinic acid is a dicarboxylic acid containing a thiol functional group. As suggested by its name, it contains a thiol group (SH) in place of the hydroxy group (OH) in malic acid. Salts and esters are known as thiomalates.

  3. Succimer - Wikipedia

    en.wikipedia.org/wiki/Succimer

    Succimer is an isomer of 2,3-dimercaptosuccinic acid. 2,3-dimercaptosuccinic acid is the organosulfur compound with the formula HO 2 CCH(SH)CH(SH)CO 2 H. This colorless solid contains two carboxylic acid and two thiol groups, the latter being responsible for its mildly unpleasant odour.

  4. Thioglycolic acid - Wikipedia

    en.wikipedia.org/wiki/Thioglycolic_acid

    Thioglycolic acid with a pK a of 3.83 [7] is an acid about 8.5 times stronger than acetic acid (pK a 4.76): HSCH 2 CO 2 H → HSCH 2 CO 2 − + H + The second ionization has a pK a of 9.3: HSCH 2 CO 2 − → − SCH 2 CO 2 − + H + Thioglycolic acid is a reducing agent, especially at higher pH.

  5. Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate - Wikipedia

    en.wikipedia.org/wiki/Bis(2,2,6,6-tetramethyl-4...

    Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (abbreviated BTMPS) is a hindered amine light stabilizer used to protect plastics and coatings such as paint from oxidation caused by weathering. like most compounds of this class, it's active form is an aminoxyl radical.

  6. Stabiliser (food) - Wikipedia

    en.wikipedia.org/wiki/Stabiliser_(food)

    Pectin is used as a stabiliser in foods such as yogurt. A stabiliser or stabilizer is an additive to food which helps to preserve its structure. Typical uses include preventing oil-water emulsions from separating in products such as salad dressing; preventing ice crystals from forming in frozen food such as ice cream; and preventing fruit from settling in products such as jam, yogurt and jellies.

  7. Emulsion stabilization using polyelectrolytes - Wikipedia

    en.wikipedia.org/wiki/Emulsion_stabilization...

    Polyelectrolytes are charged polymers capable of stabilizing (or destabilizing) colloidal emulsions through electrostatic interactions. Their effectiveness can be dependent on molecular weight, pH, solvent polarity, ionic strength, and the hydrophilic-lipophilic balance (HLB).

  8. Polymer stabilizer - Wikipedia

    en.wikipedia.org/wiki/Polymer_stabilizer

    Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of ...

  9. Stabilizer (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Stabilizer_(chemistry)

    In industrial chemistry, a stabilizer or stabiliser is a chemical that is used to prevent degradation. [1] Above all, heat and light stabilizers are added to plastic and rubber materials because they ensure safe processing and protect products against aging and weathering.
