PEG-40 Lanolin is a lanolin-derived cosmetic ingredient produced by ethoxylating lanolin with an average of approximately 40 moles of ethylene oxide. It is primarily used as a surfactant and emulsifying ingredient in cosmetic and personal care formulations. Its modified structure supports the incorporation and dispersion of compatible oil-based components in suitable formulation systems.
PEG-40 Lanolin can be evaluated in selected skincare products, creams, lotions, haircare preparations, cleansing products and other compatible personal care formulations. Depending on the commercial grade and complete formula, it may help improve ingredient compatibility, emulsification and the texture of the finished product.
Swapnroop supports cosmetic ingredient enquiries for manufacturers, formulators and personal care businesses. Before procurement, confirm the ingredient identity, commercial grade, technical specifications, current availability and supporting quality documentation.
PEG-40 Lanolin is an ethoxylated derivative of lanolin, a complex wax-like material obtained from sheep's wool. Ethoxylation introduces polyethylene glycol chains into the ingredient, changing its interaction with water and other formulation components.
The number “40” represents an average of approximately 40 ethylene oxide units associated with the ingredient. Because lanolin is a complex mixture, PEG-40 Lanolin does not have one simple universal molecular formula or molecular weight.
Its recognised cosmetic functions include surfactant-emulsifying and surfactant-cleansing activity. Emulsifiers help compatible oil and water phases form a more uniform mixture, while surfactants can support the dispersion and cleansing performance of suitable cosmetic formulations.
PEG-40 Lanolin should be distinguished from PEG-40 Hydrogenated Lanolin and PEG-40 Sorbitan Lanolate. These are separate ingredient identities and should not share product specifications without supporting documentation.
Actual performance depends on the commercial grade, concentration, processing method and formulation composition. These properties should be validated through compatibility and stability testing.
PEG-40 Lanolin can be evaluated in compatible skincare formulations where emulsifying or surfactant functionality is required. Formulators should assess its contribution to product appearance, consistency and stability.
The ingredient may be considered for suitable cosmetic emulsions containing compatible oil and water phases. Its performance should be assessed alongside other emulsifiers, emollients and functional ingredients in the formula.
PEG-40 Lanolin can be evaluated in selected haircare formulations where its surfactant properties are appropriate. Compatibility with the other ingredients and the intended finished-product characteristics should be confirmed through testing.
Certain lanolin-derived ethoxylated ingredients are used in hair tonics and styling preparations. PEG-40 Lanolin may be assessed for suitable applications when supported by the commercial grade's technical documentation and formulation trials.
PEG-40 Lanolin has a recognised surfactant function and can be considered for compatible cleansing systems. Formulators should evaluate its interaction with the primary surfactants, oils and other components in the finished product.
PEG-40 Lanolin may be evaluated for incorporating selected fragrance materials into compatible cosmetic systems. The required concentration and stability depend on the fragrance composition, the base formulation and the grade being used.
Research and development teams can evaluate PEG-40 Lanolin in laboratory and pilot batches to establish compatibility, processing conditions and finished-product stability before production scale-up.
Before incorporating PEG-40 Lanolin into a cosmetic product, review the current technical data sheet and Safety Data Sheet for the selected grade.
Do not assume that PEG-40 Lanolin and PEG-40 Hydrogenated Lanolin have identical properties, CAS numbers or acceptance specifications.
Swapnroop supports cosmetic ingredient enquiries for manufacturers and personal care businesses developing skincare, haircare, cleansing and other cosmetic formulations.
Before procurement, confirm the available grade, current specifications, packaging options, order quantity and supporting quality documentation. This helps ensure that the selected ingredient meets the technical requirements of the intended formulation.
PEG-40 Lanolin is a lanolin-derived cosmetic ingredient used primarily for its surfactant and emulsifying functions. It can be evaluated for compatible skincare, haircare, cleansing and other personal care applications.
Cosmetic manufacturers and formulators in India should verify the commercial grade and current specifications before use. Contact Swapnroop to enquire about availability, packaging and technical documentation. Manufacturing and supply claims should accurately reflect verified business capabilities.
PEG-40 Lanolin is an ethoxylated derivative of lanolin used in cosmetic formulations primarily as a surfactant and emulsifying ingredient.
The commonly referenced CAS number is 61790-81-6. Confirm this identifier against the technical documentation for the actual commercial grade.
PEG-40 Lanolin can be evaluated in compatible skincare, haircare, cleansing, cream, lotion and other personal care formulations where surfactant or emulsifying functionality is required.
The number indicates an average of approximately 40 ethylene oxide units associated with the ethoxylated ingredient.
Yes. Cosmetic ingredient references identify PEG-40 Lanolin as a surfactant-emulsifying ingredient. Its actual performance depends on the commercial grade and complete formulation.
PEG-40 Lanolin is ethoxylated lanolin, whereas PEG-40 Hydrogenated Lanolin is based on hydrogenated lanolin. They are distinct ingredient identities with different reference records and potentially different properties.
It can be evaluated in compatible skincare products where emulsifying or surfactant functionality is required. Suitability should be established through formulation and stability testing.
It may be considered for selected haircare formulations where its surfactant properties are appropriate. The selected grade and finished formula should be tested for compatibility.
Confirm the INCI name, CAS number, appearance, applicable physicochemical parameters, grade-specific acceptance limits, storage requirements and batch Certificate of Analysis.
Manufacturers can contact Swapnroop to enquire about current availability, commercial grades, packaging and technical documentation.
