Fermentation cosmetic ingredients instead of shark-liver squalene, rooster-comb hyaluronic acid and animal collagen

Replaces: shark squalene, rooster-comb HA, animal collagen · Scope: skin-care actives · Evidence: high (HA, squalane)

The chemical problem#

• Squalene was classically rendered from deep-sea shark liver oil (livers up to a third of body weight). Shark species are slow to reproduce; conservation pressure (and EU deep-sea fishing restrictions) pushed the industry to plant and fermentation sources.
• Hyaluronic acid (HA) was first commercialized from rooster combs — an animal by-product with traceability, certification (halal/kosher/vegan) and consistency problems.
• Collagen from bovine/porcine hide/bone carries the same certification burden plus consumer-animal-welfare expectations in premium skincare.
• These are not “toxic chemicals” — the problem class here is unsustainable animal sourcing, the cosmetic face of the same substitution logic the catalogue applies to hazard.

Product overview#

1. Sugarcane squalane (squalene hydrogenated to stable squalane): farnesene from yeast fermentation of Brazilian sugarcane → squalene → squalane. Now the mainstream source; identical molecule to shark-derived (C₃₀ isoprenoid).
2. Fermentation HA: Streptococcus zooepidemicus/equi fermentation → sodium hyaluronate at food/cosmetic/pharma grades. China’s fermentation HA cluster supplies the majority of the world market — Bloomage and Baotou Dongbao are among the largest producers globally (both in this index).
3. Collagen-equivalents: yeast-fermented recombinant collagen fragments/peptides and “collagen-boosting” signal peptides (commercial, e.g. in Chinese and Korean premium skincare); full-length recombinant collagen is scaling but not yet a complete hide-collagen replacement.

Active ingredient / Composition#

• Squalane: C₃₀H₆₂, saturated hydrocarbon, exceptional oxidative stability, skin-identical emollient (2–30 % of formula).
• Sodium hyaluronate: glycosaminoglycan, MW 10 kDa–2 MDa; low MW penetrates, high MW films.
• Recombinant collagen peptides/fragments with declared sequences; hydrolyzed collagen (animal) remains the reference for full structure.

Key facts#

Advantages#

• No sharks, no combs, no hides — traceability and certification problems disappear with the animal.
• Fermenter-sited supply: price and quality stability, no fishery volatility.
• Molecular identity with the animal version (squalane) — no consumer-perceptible trade-off.
• Same sugar feedstocks as the ethanol/food-ingredient clusters of this index (EN02, FI01).

Mode of action#

• Biology: engineered yeast mevalonate pathway → farnesene → farnesene dimerization to squalene; Streptococcus HA synthase polymerizes UDP-glucuronate + UDP-N-acetylglucosamine to the HA chain; secreted recombinant collagen fragments from yeast.
• Skin: squalane as biomimetic emollient; HA water-binding (up to 1,000× its weight) and barrier film; collagen peptides as signalling/moisturizing agents.

Application#

Limitations#

• INCI names don’t reveal the source — greenwashing risk; verify supplier dossiers.
• Full-length recombinant collagen is not yet a full replacement for animal collagen in structural uses (medical-grade especially).
• Fermentation HA capacity is concentrated in a few producers — supply concentration risk.
• Cost of recombinant peptides remains premium-tier.

Evidence of displacement — D1: works, adoption not proven#

Verified figures (the number is in the quoted sentence and the sentence is on the source page):

• displacement — A substantial share, above 70%, of hyaluronic acid production already uses microbial fermentation. (global, 2024-2025; weak: futuremarketinsights.com)
• displacement — In 2013, global squalane production was 2,500 metric tonnes, with 1,050 MT from olive oil, 1,000 MT from shark liver, and 450 MT from Amyris (microbial fermentation). (global, 2013; weak: etcgroup.org)

Bioeconomy value#

Cosmetics is where bioeconomy sourcing commands a price premium instead of a cost fight: the fermentation versions of squalane and HA outsold their animal predecessors on ethics and consistency, with the world’s supply concentrated in exactly the Asian fermentation industry this index maps.
