Tridecane is a saturated hydrocarbon belonging to the alkane family. It contains 13 carbon atoms and is identified by the molecular formula C₁₃H₂₈. In cosmetic ingredient applications, Tridecane is associated with emollient and skin-conditioning functions. Its suitability for a formulation depends on the supplied grade, purity, intended use, and compatibility with the complete formulation.
Tridecane may be considered by cosmetic formulators developing selected skin-care, personal-care, and specialty cosmetic products. However, the chemical identity of the material should be confirmed before procurement because Tridecane, Tridecyl Alcohol, and other C13-related ingredients are chemically different substances.
Tridecane, also known as n-Tridecane when referring to the straight-chain isomer, is an aliphatic alkane. Its molecular structure consists of a chain of 13 carbon atoms connected by single bonds and saturated with hydrogen atoms.
As a non-polar hydrocarbon, Tridecane differs from fatty alcohols, triglyceride oils, esters, and silicone-based emollients. These differences affect its solubility, compatibility, sensory profile, and role within a cosmetic formulation.
The term Tridecane may also appear in chemical and natural-product analyses. Therefore, a material intended for cosmetic use should be identified by its precise chemical name, CAS number, grade documentation, and supplier technical information.
Tridecane has the molecular formula C₁₃H₂₈ and a molecular weight of approximately 184.36 g/mol. The straight-chain form is commonly identified by CAS Number 629-50-5.
Important identity details include:
These characteristics describe the identified chemical substance rather than a guaranteed commercial cosmetic grade. Colour, odour, purity, impurity profile, and other acceptance criteria must be confirmed using the documentation supplied for the actual material.
Tridecane is listed as a skin-conditioning ingredient in cosmetic ingredient references. Its suitability for a particular product depends on its grade, concentration, and interaction with other ingredients.
As an emollient-associated hydrocarbon, Tridecane may be evaluated for its contribution to the sensory and application characteristics of selected formulations. The final effect on spreadability, slip, and skin feel should be established through formulation trials rather than assumed from chemical identity alone.
Tridecane may be considered during the development of hydrocarbon-containing cosmetic systems where a non-polar ingredient is relevant. Its use must be evaluated alongside the formulation's oils, emollients, solvents, emulsifiers, and other components.
Because Tridecane is non-polar and does not mix readily with water, formulators should assess its distribution within the oil phase or other suitable formulation environment. Compatibility depends on the overall composition and processing conditions.
Potential application areas should be selected according to the supplier's documented cosmetic-grade status and the formulator's testing.
These are potential evaluation areas, not a claim that every Tridecane grade is approved or suitable for every cosmetic product category.
Tridecane is a saturated hydrocarbon with low polarity and limited compatibility with water. These characteristics distinguish it from water-soluble humectants and polar ingredients.
Before incorporating it into a formulation, assess:
Tridecane is combustible. Appropriate precautions should be based on the supplier's Safety Data Sheet, including guidance for storage, ventilation, ignition-source control, and handling.
Tridecane should be incorporated only after the intended application and grade have been confirmed. Formulators should review the technical data sheet and certificate of analysis for the exact material.
A practical evaluation process includes:
No universal use concentration should be assumed for all Tridecane materials or product types. The appropriate level, if applicable, must be established through qualified formulation development and relevant product requirements.
Tridecane and Tridecyl Alcohol are not interchangeable names.
The difference is important when purchasing ingredients, preparing product specifications, entering INCI information, and creating cosmetic product labels. Always confirm the exact ingredient identity against the supplier's documentation.
For cosmetic ingredient procurement, buyers should request documentation appropriate to the intended use. Depending on the grade and supplier, relevant records may include:
A laboratory or industrial grade should not automatically be treated as suitable for cosmetic manufacturing. Suitability must be supported by the material's documentation and the requirements of the finished product.
Swapnroop supports ingredient sourcing for businesses seeking clearly identified materials and technical information for formulation development.
The availability of specific grades, quantities, and documents should be confirmed directly with Swapnroop before procurement.
Businesses searching for a Tridecane cosmetic ingredient manufacturer in India should verify the source, chemical identity, quality documentation, and suitability of the offered grade. For cosmetic formulation work, the material's intended use and supporting documentation are as important as the product name.
Swapnroop provides a point of contact for enquiries concerning ingredient requirements, technical information, and procurement suitability. Buyers should communicate their intended application and required documentation so the offered material can be evaluated against their specifications.
Tridecane is associated with skin-conditioning and emollient functions in cosmetic ingredient references. Its suitability for a specific formulation depends on the grade and supporting technical documentation.
The CAS Number for straight-chain n-Tridecane is 629-50-5. Verify the identifier against the exact material being purchased.
The molecular formula of Tridecane is C₁₃H₂₈.
The molecular weight of n-Tridecane is approximately 184.36 g/mol.
Tridecane is a non-polar hydrocarbon and is practically insoluble in water.
No. Tridecane is an alkane, whereas Tridecyl Alcohol contains an alcohol functional group. Their chemical properties and applications differ.
No. Cosmetic suitability must be confirmed using the grade's documentation, purity information, safety assessment, and the requirements of the intended finished product.
Request the available COA, TDS, SDS, chemical identity confirmation, and information establishing suitability for the intended application.
Follow the storage and handling instructions in the supplier's SDS. Because Tridecane is combustible, appropriate precautions against ignition sources and unsuitable storage conditions are necessary.
For straight-chain n-Tridecane, verify 629-50-5 against the supplier's documentation before using it in product records or purchasing specifications.
