Biolime is a natural cosmetic ingredient produced by BIOLIe. It is made from Aqua, Propanediol, and Citrus Aurantifolia (Lime) Fruit Extract. CREATED THROUGH AN ENZYMATIC EXTRACTION METHOD This formulation is designed to meet the increasing demand for high-performance, plant-based ingredients in skincare products. Propanediol acts as a bio-based solvent and humectant, IMPROVING the delivery of active compounds WHILE maintaining the skin’s moisture balance.

Citrus Aurantifolia, known for its rich composition of antioxidants and natural acids, offers gentle exfoliation, skin-brightening properties, and improved hydration. Combined with Aqua as the carrier, these elements ensure compatibility and efficacy in a wide range of personal care formulations. Whether in moisturizers, serums, or other skincare products, Biolime provides formulators with a versatile and effective ingredient for addressing skin tone and texture concerns.

Composition and Origins of Aqua, Propanediol, and Lime Fruit Extract

Citrus Aurantifolia (Lime) extract, native to Southeast Asia and widely cultivated in tropical regions, has been used for centuries in skincare due to its natural abundance of citric acid and antioxidants. Historical accounts show its application in cleansing rituals and as a natural treatment for uneven skin tone, utilizing its exfoliating and brightening properties long before the arrival of modern cosmetics. 

Enzymatic extraction techniques now isolate key bioactive compounds from lime, such as alpha-hydroxy acids (AHAs), polyphenols, and vitamin C, while minimizing the environmental impact of production. This refined process ensures a stable, effective ingredient suitable for addressing hydration, skin renewal, and mild exfoliation in formulations.

Applications of Biolime in Skincare Formulations

Biolime is a versatile ingredient designed for targeted skincare applications, offering benefits thanks to its balanced composition of hydration-boosting agents, bioactive exfoliants, and antioxidants. This multifunctional compound is suited for various product types and consumer needs.

• Hydration and Moisture Retention: Biolime supports skin hydration by integrating Propanediol’s humectant properties with water-attracting compounds that bind moisture to the epidermis. These hydrophilic interactions improve skin hydration levels over time, creating a plump and smooth texture. Biolime is especially beneficial in products targeting dryness-prone or mature skin, where moisture retention is a critical concern.

• Exfoliation Through Alpha-Hydroxy Acids (AHAs): Citrus Aurantifolia (Lime) extract in Biolime is a natural source of AHAs, primarily citric acid, which gently dissolves the bonds between keratinized skin cells. This enzymatic exfoliation encourages cellular turnover, revealing a brighter complexion and smoother skin texture. Unlike harsh chemical exfoliants, Biolime’s balanced formulation ensures minimal irritation, making it suitable for sensitive skin types.

• Antioxidant Protection: Rich in vitamin C, polyphenols, and flavonoids, Biolime’s lime extract component delivers potent antioxidant activity. These compounds neutralize free radicals responsible for oxidative stress, slowing the progression of visible signs of aging such as wrinkles, pigmentation, and loss of elasticity. Incorporating Biolime into antioxidant-focused formulations improves their efficacy in protecting skin vitality.

• Formulation Synergies and Versatility: Biolime’s compatibility with emulsifiers, stabilizers, and other active compounds makes it adaptable for diverse skincare products, such as serums, moisturizers, and exfoliating treatments. Its dual action as a hydrating and exfoliating agent reduces the need for additional ingredients, simplifying formulations while retaining efficacy.

Synergistic Interactions of Biolime with Other Actives

Biolime’s composition makes it an excellent partner for a variety of cosmetic actives, increasing their efficacy through complementary chemical interactions. 

Sodium Ascorbyl Phosphate (Stabilized Vitamin C)

• Chemical Interaction: It works synergistically with Biolime by amplifying its antioxidant and brightening effects. The vitamin C derivatives in Biolime boost the bioavailability of ascorbic acid, neutralizing free radicals and supporting collagen synthesis. The lime extract’s AHAs improve vitamin C absorption by increasing skin permeability. Use at 0.5–2% concentrations. Ensure pH levels remain within 5.0–6.0 to stabilize sodium ascorbyl phosphate and prevent oxidative degradation.

• Applications: Brightening serums, anti-pollution creams, or rejuvenating masks.

Niacinamide (Vitamin B3)

• Chemical Interaction: It interacts with Biolime’s AHAs by improving the skin’s response to exfoliation. While the AHAs in lime extract promote cellular turnover through desmosome dissolution, niacinamide supports post-exfoliation skin recovery by increasing ceramide production. This lipid reinforcement prevents barrier damage and reduces inflammation caused by the acidic environment. Use niacinamide at concentrations of 2–5%, maintaining the formulation’s pH between 4.5–5.5 to avoid destabilizing either compound. Lower pH levels risk hydrolyzing niacinamide into nicotinic acid, which may cause skin irritation.

• Applications: Brightening creams, daily serums, or barrier-repairing formulations.

Panthenol (Vitamin B5)

• Chemical Interaction: Panthenol stabilizes and soothes the skin by converting it into pantothenic acid upon application. When paired with Biolime’s exfoliating AHAs, it reduces transepidermal water loss (TEWL) and mitigates potential irritation, especially in sensitive skin types. Propanediol’s humectant action increases panthenol’s barrier-restoring properties. Recommended usage levels are 1–5%, with an optimal pH range of 4.0–5.0 to balance AHA activity and panthenol stability. Panthenol’s water-soluble nature makes it ideal for emulsions or water-based serums.

• Applications: Hydrating moisturizers, calming serums, or post-treatment repair products.

Centella Asiatica Extract

• Chemical Interaction: Rich in triterpenoids, Centella Asiatica improves skin repair and has soothing effects when combined with Biolime. The exfoliation facilitated by AHAs improves the delivery of Centella’s active compounds, such as madecassoside, which promote collagen synthesis and wound healing. Recommended usage is 1–3%, targeting repair-focused formulations. Maintain a pH range of 4.0–5.5 for compatibility with both actives.

• Applications: Soothing serums, scar treatments, or post-inflammatory repair products.

Key Considerations for Skincare Products Featuring Biolime

Skincare products featuring Biolime must balance their multi-functional properties to meet diverse formulation goals, from hydration to exfoliation. Below are key considerations for leveraging Biolime effectively in cosmetic development:

• pH Optimization: Biolime’s alpha-hydroxy acids (AHAs) function best within a pH range of 3.5 to 4.5, where their exfoliating and cell turnover properties are maximized. However, maintaining a pH above 4.0 is crucial for compatibility with sensitive actives like niacinamide or stabilized vitamin C derivatives, which degrade at lower acidity levels.

• Formulation Stability: The enzymatic extraction of lime extract ensures the preservation of active compounds like citric acid and vitamin C. To maintain their efficacy, avoid prolonged exposure to light, heat, or oxygen during production and packaging. Airless dispensers or amber-colored containers can increase product stability.

• Packaging Considerations: Given Biolime’s sensitivity to light and oxidation, airless pumps or opaque containers are recommended. Avoid formulations that require high-temperature processing to protect the bioavailability of active compounds like polyphenols and vitamin C.

The Takeaway

Biolime demonstrates exceptional versatility and efficacy in modern skincare formulations. Its combination of alpha-hydroxy acids, humectants, and antioxidants supports hydration, exfoliation, and environmental defense, addressing multiple consumer needs. Biolime’s enzymatic production process and multi-functional profile offer an opportunity to create products that align with eco-conscious trends.
