COSMETICS & PERSONAL CARE
La Garenne-Colombes, France · Founded 1943 · Part of Air Liquide since 1986
Formulation architecture, engineered as carefully as the active.
Seppic develops ingredients for formulation structure, texture, sensory performance and cosmetic efficacy, including polymers, emulsifiers, emollients and active ingredients.
Founded in 1943 and part of the Air Liquide group since 1986, Seppic works across personal care, pharmaceutical excipients, nutrition, and vaccine adjuvants. That breadth brings experience across personal care, pharmaceutical excipients, nutrition and vaccine-related applications, alongside Seppic's cosmetic ingredient expertise.
ABOUT THIS PRINCIPAL
Eight decades of chemistry for skin.
Seppic was founded in 1943 by French chemist Andre Bondouy and grew through the acquisition of chemical manufacturing at Castres, then through a sustained programme of proprietary polymer and emulsifier development. In the 1990s it produced Montanov 65, an early example of green chemistry in cosmetic emulsification, and later Sepigel 305, the first pre-neutralised polymer supplied as an inverse emulsion, which made gel-cream textures routine rather than difficult.
The active side of the business was built by acquisition and integration: BiotechMarine in 2013 brought marine biotechnology and plant cell culture, and Serdex in 2017 brought botanical actives for skin treatment. The result is a portfolio combining formulation ingredients with active ingredients and supporting technical and efficacy documentation.
Seppic is unusual because it treats the excipient as a performance decision, not a filler decision. The polymer, the emulsifier, and the emollient are where most reformulation projects actually succeed or fail.
ADCHEM distributes the Seppic personal care range with formulation support from our own laboratories. Customers receive the raw material together with a tested starting formulation, so a Sepimax Zen chassis or a Montanov emulsion system arrives as a working prototype rather than a datasheet.
FEATURED TECHNOLOGY
Four technology platforms relevant to a wide range of formulation briefs.
Seppic's portfolio is easier to navigate as platforms than as an alphabetical product list. Most projects draw on two or three of the following.
POLYMER PLATFORM
Inverse emulsion polymerisation
Pre-neutralised liquid and powder polymers designed to provide thickening, stabilisation and texturising properties. The range includes Sepigel 305, Sepinov, Sepiplus and Sepimax Zen, with product-specific performance characteristics.
EMULSIFICATION PLATFORM
Alkyl polyglucoside chemistry
The Montanov range builds naturally derived O/W systems with liquid crystal structure, covering everything from sprayable milks to rich butters. Natural-origin emulsification options with product-specific formulation and stability characteristics.
SENSORY PLATFORM
Plant-based non-polar emollients
Emogreen and Emosmart grades provide selected spreading and sensory profiles for formulations seeking alternatives to conventional silicone-based sensory modifiers.This is the practical answer to a silicone-free brief that still has to feel premium.
ACTIVE PLATFORM
Marine and plant biotechnology
Plant cell culture, algae-derived and botanical active ingredients from Seppic's BiotechMarine and Serdex expertise, with product-specific in vitro and/or in vivo study data available where applicable..

WORKING WITH ADCHEM
What ADCHEM adds to the Seppic relationship.
SAMPLE PLUS PROTOTYPE
Formulation integration in our own labs
Our formulation teams work with the Seppic polymer and emulsifier ranges directly. A customer can receive the raw material and a tested starting formulation in the same engagement.
DOSSIER-READY
Chassis-first reformulation support
Most reformulation briefs stall on rheology and stability rather than on the active. We start there, then bring the active in once the chassis holds.
SUBSTITUTION TESTING
Claim substantiation files
Study summaries, mechanism explanations, and supporting publications compiled for the active you are actually using, in the format your regulatory reviewer expects.
AUTO-ATTACHED VIA COSMO
Full documentation with every sample
Available TDS, SDS, CoA, composition information and applicable certificates can be provided for the selected product through ADCHEM's documentation process, subject to product-specific availability and applicable confidentiality requirements.
