Ethylhexyl Dimethyl PABA -CAS 21245-02-3

Ethylhexyl Dimethyl PABA -CAS 21245-02-3

• Ethylhexyl Dimethyl PABA, commercially known as Padimate O, is a high-purity cosmetic grade oil-soluble UVB filter refined by advanced esterification reaction, purification and distillation technology.

• It is a classic and widely used core functional raw material in the global high-end sunscreen and personal care industry, derived from PABA (para-aminobenzoic acid) and optimized for cosmetic application.

• Different from traditional water-soluble PABA with poor oil compatibility, easy to cause skin irritation and poor photostability, and ordinary oil-soluble UVB filters with low absorption efficiency and heavy texture, Padimate O has a unique ethylhexyl dimethyl PABA molecular structure, which is a typical oil-soluble UVB absorber.

• It can efficiently absorb ultraviolet rays in the 280-320nm band, with a peak absorption at 311nm, forming a uniform and dense protective barrier on the skin surface to effectively resist UVB radiation damage, prevent skin sunburn, redness, peeling and long-term photoaging problems such as fine lines, pigmentation and skin roughing.

• As a multi-functional sunscreen raw material integrating UV protection, formula stabilization and synergism, it not only has excellent UVB absorption capacity, but also can act as a stabilizer and synergist for other UV filters (such as Avobenzone, Octinoxate and Zinc Oxide), improving the photostability and SPF value of other sunscreen agents, avoiding their decomposition under sunlight, and extending the effective protection time of sunscreen products, especially for waterproof and outdoor high-SPF sunscreen formulations.

• It is pale yellow oily liquid with good oil solubility, can be quickly dissolved in the oil phase of cosmetic formulas, has good compatibility with various oil-based raw materials, will not cause heavy or greasy feeling on the skin when used in an appropriate proportion, and will not leave white residue on the skin surface, bringing a smooth and comfortable use experience.

• The product has excellent chemical stability and photostability, can be perfectly compatible with various cosmetic raw materials such as oil-based emulsifiers, plant oils, waxes and functional active substances, no precipitation or delamination, no oxidation, discoloration or peculiar smell during long-term storage and normal processing, mild and low-irritation, non-sensitizing, non-comedogenic, no harmful impurities such as heavy metals, passed multiple skin safety tests and cosmetic raw material safety certifications, suitable for normal skin, oily skin, combination skin and dry skin, and is the core raw material for creating high-protection, waterproof and durable sunscreen cosmetic formulas, especially suitable for oil-based and water-in-oil sunscreen products and outdoor sun care products.

Key Benefits

• High-efficiency UVB Protection, Stable Sun Defense: As a classic oil-soluble UVB filter, it efficiently absorbs ultraviolet rays in the 280-320nm band, with a peak absorption at 311nm, forming a dense protective barrier on the skin surface to prevent sunburn, redness and long-term photoaging caused by UVB radiation, with stable and reliable protection effect, and is the preferred raw material for high-SPF and waterproof sunscreen products.

Frequently Asked Questions (FAQ)

• Q1: What is the core advantage of Padimate O compared with ordinary UVB filters? 

A1: Ordinary UVB filters are mostly water-soluble with poor oil compatibility and low photostability, while Padimate O is a high-efficiency oil-soluble UVB filter, with high absorption efficiency, excellent photostability, good compatibility with oil-based formulas, and can stabilize other sunscreen agents to enhance protection effect, with more comprehensive performance advantages, especially suitable for waterproof and high-SPF sunscreen formulations.

• Q2: What is the recommended addition ratio for different cosmetic formulas? 

A2: 2.0%-6.0% for daily oil-based skincare products with sunscreen function, 5.0%-15.0% for professional waterproof and outdoor sunscreen products, 1.0%-4.0% for makeup with sunscreen function (oil-based type), 2.0%-5.0% for lip care and outdoor care products, adjustable according to SPF value requirements and formula texture.

• Q3: Is Padimate O suitable for sensitive skin and infant care formulas? 

A3: It is mild and low-irritating, refined by high-purity process, free of harmful impurities such as heavy metals, passed safety tests for sensitive skin, but it is recommended to control the addition ratio (≤5.0%) when used in infant care formulas, and conduct skin sensitivity tests before use to ensure safety.

• Q4: Can it be compounded with inorganic sunscreen agents and other organic sunscreen agents?
