What Is Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate?
Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate is a bio-fermented blend created when the yeast Pseudozyma epicola feeds on soybean flour and olive fruit oil. During fermentation the yeast breaks down proteins fats and sugars into smaller skin-friendly pieces such as amino acids peptides and lightweight lipids. After the process finishes the mixture is filtered to remove the yeast itself leaving a clear liquid rich in these beneficial fragments.
Interest in fermented ingredients grew over the past decade when formulators noticed that the by-products of fermentation often leave skin and hair feeling softer and looking healthier. This particular filtrate entered cosmetic labs as brands searched for plant-based actives that could replace synthetic conditioners without adding heaviness.
The ingredient is manufactured in controlled tanks where soybean flour and olive oil are combined with water nutrients and the yeast culture. Temperature and pH are kept steady so the yeast can work for several days. The final liquid is then filtered and preserved for stability before it heads to formulation benches.
You will spot Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate in leave-on hair creams rinse-off conditioners hydrating face serums soothing masks lightweight moisturizers and many age-support formulas that aim to improve smoothness and suppleness.
Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate’s Cosmetic Benefits/Uses
This ferment filtrate earns its place on ingredient lists thanks to two key functions
- Hair conditioning: coats strands with lightweight proteins and lipids that help reduce roughness boost shine and improve manageability without weighing hair down
- Skin conditioning: supplies amino acids and sugars that enhance moisture retention soften the skin surface and promote a smoother more flexible feel which can visually reduce fine lines
Who Can Use Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate
This ferment filtrate suits most skin and hair types including dry, normal, combination, oily and even sensitive skin because it feels light, boosts moisture and has a low scent and color profile. Very acne-prone users who react to any fermented ingredient or to the fatty acids found in olive oil may want to watch for congestion, but such issues are uncommon.
The ingredient is made from soybean flour, olive fruit oil and a yeast culture so it is completely plant derived and cruelty free, making it appropriate for vegans and vegetarians.
Based on its makeup and the low use levels found in finished formulas it is generally viewed as safe for people who are pregnant or breastfeeding. This is not medical advice, and anyone who is expecting or nursing should ask a doctor before starting a new cosmetic product just to be sure.
Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate is not known to cause photosensitivity, so sun exposure rules do not change when you apply it. It also plays well with most other common skincare actives, meaning you can layer it with vitamin C, niacinamide or gentle exfoliating acids without extra fuss.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate can vary from person to person. The points below list potential outcomes that are possible yet unlikely for the average user as long as the product has been formulated and stored correctly.
- Allergic reaction in people sensitive to soy, olive or yeast derivatives leading to redness, itching or hives
- Mild irritation such as stinging or burning on very reactive or compromised skin
- Fungal acne-like bumps in individuals who are highly prone to Malassezia overgrowth
- Scalp or skin buildup if a leave-on hair or body product containing a high level of the filtrate is not washed off regularly
- Rare contact dermatitis if the preservative system in the finished formula disagrees with the user
If you experience any of the reactions above discontinue use immediately and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 1 / 5 – The filtrate contains only trace levels of olive-derived fatty acids and most of the ferment by-products are water soluble amino acids and sugars, so it is unlikely to clog pores. Those with very reactive, blemish-prone skin can usually use it without triggering breakouts, though individuals who know they react to fermented ingredients or olive oil should stay alert. Because the ingredient is processed at low usage levels and is easily rinsed or absorbed, any comedogenic risk is minimal.
One extra point to consider is that the small amount of natural oil in the filtrate is rich in oleic acid, which some very oily skins dislike. If you notice congestion when using olive-based products, monitor your skin’s response.
Summary
Pseudozyma Epicola/Olive Fruit Oil/Soybean Flour Ferment Filtrate acts primarily as a hair and skin conditioner. During fermentation the yeast breaks down soybean proteins and olive lipids into tiny peptides, amino acids and lightweight oils that can slip into rough spots along the hair cuticle and skin surface, locking in moisture and leaving a smooth, supple finish.
The ingredient is still a niche choice compared with better known ferments like galactomyces or bifida, yet formulators who want vegan, plant-based alternatives to silicone or animal keratin are beginning to include it in leave-on creams, masks and serums.
Overall safety is high thanks to its food-grade origin, low use levels and gentle chemistry. Adverse reactions are rare but always possible, so do a quick patch test when trying any new product containing this ferment to make sure it agrees with your skin.
