About wesource, the brand for cosmetic active ingredients

When it comes to Beauty, we believe that there is no greater inspiration than life itself. For us, active science means being curious about the world. It means being inspired by the raw materials that make up life, and which, when combined with innovation, create solutions that truly empower beauty.

Wesource, the go-to designer offering performing and innovative active ingredients and services “haute couture” to accompany our clients all along their projects to reveal the beauty of all skin types.

Botanical extraction

Fully embracing biodiversity and respecting traditional know-hows around the world, we explore the power of plants. We seek high-performance active ingredients obtained by extracting and purifying ethically grown and harvested plants.

Marine biotechnologies

We connect you to the magical world of marine active ingredients. The Bréhat archipelago, the “underwater Amazon” is a pure and preserved site, a treasure trove of inspiration. We create substantiated active ingredients while fully preserving the natural biodiversity and developing biotechnologies in harmony with the marine ecosystem.

Plant-based chemistry

Both the raw materials that make up life and our expertise in responsible chemistry are an inexhaustible source of inspiration. We create innovative and eco-designed molecules to empower beauty, such as Aminovector (lipoaminoacids), sugars, and minerals.

About Seppic functional ingredients

Polymeric thickeners and stabilisers

In the world of beauty, Seppic is a pioneer in polymer science. Known for their ease of use and their thickening and stabilizing properties, our polymers are adapted to the most complex formulations.

Just as Sepigel 305 revolutionised formulations when first launched, Seppic continues to develop new solutions to create novel sensory experiences.

And at a time when beauty is becoming more minimalist and eco-responsible, our versatile polymers can be formulated cold, open up an unlimited world of creativity for formulators while reducing environmental impact.


Pioneer in the creation of alkylpolyglucosic (APG) emulsifiers on long carbon chains, 100% of natural origin, for beauty and care, Seppic continues, since the 90s, to magnify nature in order to remain as close as possible to the evolution of the cosmetics market.

Thanks to its great expertise in formulation and a range of technical and sensorials ingredients, developed and produced in France, Seppic accompanies the creation of ever more efficient products.

Force of innovation and always anxious to reduce the environmental impact of emulsifiers throughout their life cycle, Seppic explores the limits of emulsions' stability to unleash your creativity!


A specialist in the chemistry of sugars and amino acid vectors, Seppic combines gentleness and effectiveness in its foaming and solubilising surfactants to remain as close as possible to the evolution of the cosmetics market, meeting in particular expectations in terms of safety, durability and well-being.

Force of innovation and always concerned to reduce the environmental impact of surfactants throughout their life cycle, Seppic opens up a world of gentleness, sensoriality and tolerance to hygiene products to unleash the creativity of formulators.

Thanks to rich, airy foams, the skin is enveloped in a cocoon of well-being, transforming cleansing into a pure moment of pleasure!

Inspiring Ingredients

AQUAXYL , the power of a patented sweetened combination, optimises the skin's hydrous flow. Its mechanism of action identified by cosmetogenomics, controls water circulation and reserves.

“Anti-dehydration shield” action: Aquaxyl reinforces the synthesis of essential lipids and proteins involved in the organisation of the corneal layer.

ANTILEUKINE 6 is a global anti-ageing and defense shield that reduces the release of inflammation mediators. It is also a DNA protector after UVA/UVB exposure. It comes from a golden seaweed: Laminaria ochroleuca.

Laminaria ochroleuca is typically found at lower depths. It is one of a small number of kelps whose tissues repel epiphytes and epifauna. Laminaria ochroleuca is exposed to a high level of salt stress and important solar variations, as it undergoes total immersion and immersion which allow it to secrete secondary metabolites to resist against UV.

Known as the golden seaweed, it has the ability to resist UV. Then we did investigate its ability to protect the skin as a DNA protection after UV stress.

EMOGREEN L19 Readily Biodegradable Alternative to Volatile Silicone Oils
EMOGREEN* is a range of liquid emollients, readily biodegradable, from vegetable origin (non GMO) that offers an alternative to silicone oils. A unique first refreshing and gliding sensation with a soft afterfeel.
*GEMSEAL BioLife Natural Alkane

MONTANOV 202 Bioinspired O/W emulsifier for visible benefits. O/W emulsifying alkylpolyglucoside, bio-based, for lotion to thick textures with a light feel. As a promoter of liquid crystals which biomimic the lipid bilayer of cellular membrane, it helps to stabilise the emulsion, provides the restructuring effect (reduction of TEWL) and the moisturising effect.

PROTEOL APL EF Naturally inspired, mild foaming agent for creamy and soft foam. Anionic surfactant derived from amino-acids characteristics of apple juice, PROTEOL APL EF adds extra mildness to all foaming formulas!

Produced using a disruptive innovation patented by SEPPIC, SEPIMAX ZEN is a next-generation thickening, stabilising and texturizing powder polymer. It has a MAXimal resistance to electrolytes and can be used to formulate with greater creativity and peace of mind.

SEPIMAX ZEN is the perfect polymer for building the “chassis” of formulations and addressing the challenge of stress-inducing and difficult active ingredients. It forms transparent gels with a velvety, rich and elegant feel. It is versatile and can be used in both skin care and hygiene products.

SEPIWHITE MSH A Amnivector star lipoaminoacid that is a phenylalanine biovector and alpha-MSH antagonist for guaranteed lightening action. With more than 5 in vivo studies, this well known molecule is the soloution for brightening.

SOLAGUM AX is obtained from a unique and innovative manufacturing process in which the Acacia gum coats the Xanthan gum. The ratio of this combination has been optimised for a perfect balance between performance and texture.

As part of Seppic’s environmental commitment, the Acacia sourcing is part of a sustainable program.

SOLAGUM AX is a 100% natural thickening and stabilising polymer. It is a water-soluble polymer that dissolves quickly and delivers outstanding sensoriality with a non-stringy, non-sticky and fresh aqueous sensation.

Its versatility allows it to be used in every cosmetic application, even for the most delicate zones (intimate hygiene, oral care).

TECA is an active ingredient dedicated to restoring the skin's integrity. This dermo repair is great for the face and body, as well as for improving the appearance of stretchmarks. It soothes the skin as well as providing ECM protection.
