Both of those Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid are preferred derivatives of Vitamin C used in skincare formulations, but they have got distinct properties that make them appropriate for different skin worries and formulations.
one. Ascorbyl Tetraisopalmitate:
Solubility: Oil-soluble
Security: Really secure; much less liable to oxidation as compared to pure Vitamin C
Penetration: Its oil-soluble mother nature will allow it to penetrate further into your pores and skin, reaching the lipid layer for enhanced usefulness.
Primary Rewards:
Powerful antioxidant action
Stimulates collagen manufacturing
Decreases hyperpigmentation and evens skin tone
Provides anti-getting old Gains by smoothing great traces and wrinkles
Considerably less irritating plus much more suited to sensitive pores and skin sorts
Usage: Prevalent in anti-getting old and brightening serums, creams, and sunscreens.
two. Ethyl Ascorbic Acid:
Solubility: Water-soluble
Stability: Reasonably steady when compared with pure ascorbic acid; far more stable than L-ascorbic acid but much less secure than Ascorbyl Tetraisopalmitate.
Penetration: For a h2o-soluble kind, it really works properly in hydrophilic environments and is also successful within the higher layers of the pores and skin.
Principal Gains:
Sturdy brightening consequences by inhibiting melanin generation
Effective antioxidant that shields towards no cost radicals
Supports collagen synthesis, selling firmness and elasticity
Lightens dim spots and enhances pores and skin tone
Usage: Commonly found in brightening serums, lightweight formulations, and drinking water-based items.
Key Variances:
Solubility: Ascorbyl Tetraisopalmitate is oil-soluble, rendering it ideal for oil-based mostly formulation and deeper skin penetration, While Ethyl Ascorbic Acid is drinking water-soluble, ideal for light-weight, water-based mostly goods.
Stability: Ascorbyl Tetraisopalmitate tends to be more stable, especially in very long-time period formulations, although Ethyl Ascorbic Ethyl Ascorbic Acid Acid is much more steady than Ascorbyl Tetraisopalmitate pure Vitamin C but can even now degrade eventually.
Pores and skin Sensitivity: Ascorbyl Tetraisopalmitate is mostly gentler and more unlikely to result in irritation, although Ethyl Ascorbic Acid is appropriate for several skin sorts but can be a little extra annoying for quite delicate skin.
Conclusion:
Each Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid supply exceptional Positive aspects as Vitamin C derivatives, but These are decided on determined by formulation demands. Ascorbyl Tetraisopalmitate is ideal for further penetration and oil-centered solutions, when Ethyl Ascorbic Acid performs properly in water-based products that has a center on brightening and antioxidant safety.
