Among beauty and personal care ingredients, ester synthetic oils have been a popular choice in recent years. It is gentle and non irritating, and can be easily integrated into various product formulas such as skincare, makeup, and wash care. It can also optimize skin feel and enhance product stability.
I. Core attributes
NSOAF ™ The three products below all belong to ester synthetic oils, which are made by esterification reaction between fatty acids and alcohols. Each product has a clear performance positioning and guaranteed quality.
1.NSOAF ™ IPP (isopropyl palmitate, CAS 142-91-6）
ISOPROPYL PALMITATE presents a transparent liquid with a chromaticity not exceeding 30 APHA, an acid value ≤ 0.5 mgKOH/g, a saponification value between 188-191 mgKOH/g, an ester content of ≥ 99%, a C16 content not less than 98%, a density of 0.848-0.853 g/cm ³, a refractive index in the range of 1.435-1.438 at 20 ℃, and overall high purity with few impurities.
Its advantages are outstanding: the skin is easy to absorb, and it can also help active ingredients such as vitamin E and plant extracts penetrate into the skin, which not only has moisturizing effects, but also has a certain antibacterial effect. Adding it to the product can make the texture smoother and easier to push, without a heavy and sticky feeling when used.
2.NSOAF ™ PTIS (Pentaerythritol Tetraisostearate, CAS 62125-22-8）
PENTAERYTHRITYL TETRAISOSTEARATE appears as a yellow liquid and is a high molecular weight synthetic ester. It has good moldability as an
Moisturizer, high waterproofness, good dispersion of colorants, good glossiness, and good adhesion and sealing properties.
Its characteristic is moisturizing: it will not feel stuffy when applied to the skin and has good breathability. When added to shampoo and conditioner, it will not affect the viscosity and foam content of the product itself, but also make the hair feel more moist and smooth. When used to make cream, it can bring a soft touch to the skin, and even dry skin will not feel greasy. High molecular weight synthetic esters have good moldability as emojis, high waterproofness, good dispersibility to pigments, good glossiness, good adhesion and sealing properties.
3.NSOAF ™ 2EHS (Ethylhexyl stearate, CAS 222047-49-0）
ETHYLHEXYL STEARATE is a transparent liquid that can be used as an moisturizer, moisturizer, and sunscreen product. It has excellent spreading and fluidity, as well as obvious thixotropy. When applied to the skin, it can bring a dry and smooth feeling without residue. In addition, it can also help to mix oil and water, which are not easy to blend, so that the lotion is more stable and the penetration effect is good. When used in conjunction with
C13 14 isoparaffin, it can enhance the film-forming and water resistance of sunscreen agents, and improve the smooth texture of the product. When used in conjunction with
Peg 40 hydrogenated castor oil for sunscreen products, it can help the sunscreen form a better film and reduce whitening.
II. Application scenarios and usage recommendations
These three products can be applied to many types of beauty and personal care products, ensuring both effectiveness and safety.
1. Skincare field
IPP: It is recommended to add 2.0-10.0%, suitable for moisturizing cream and essence. For example, when added to moisturizers, it can help the active ingredients penetrate better, making the moisturizing effect more long-lasting. Moreover, due to its high ester content, it is less likely to conflict with other oils and does not affect the stability of the formula. Even when combined with repairing ingredients such as ceramides, it can blend well.
PTIS: The recommended dosage is 1-5%, which is very suitable for cream and lotion for dry skin. For example, adding it to the repair lotion used in autumn and winter can provide sufficient moisture to the skin without making it feel stuffy, reducing the risk of acne, and adding it to the soothing cream specifically for sensitive skin can also reduce the product's irritation to the skin.
2EHS: It is recommended to add 1-5% lotion and gel suitable for oily skin. It has good spreading properties and can be quickly absorbed on the face without leaving a sticky feeling. Adding about 2% to the repair gel used in medical art can gently nourish the skin, help with skin recovery, and not add burden to the skin.
2. Makeup field
IPP: add isopropyl palmitate in liquid foundation and concealer to improve the dispersion of powder, make the face fit, reduce the powder jam, improve the makeup retention and avoid oxidation and dullness.
2EHS: It is used for lipstick and eye shadow. Adding ethylhexyl stearate can enhance the smoothness of the product, make lipstick easy to apply, and eye shadow has even color development, without affecting the waterproof of the product.
3. Washing and care field
PTIS: The addition of pentaerythritol tetraiostearate in shampoo and conditioner can wrap hair to form a protective film, improve dryness and rashness, make hair smooth and shiny after washing, and do not affect the amount of shampoo foam and cleaning power.
IPP: Can be used for shower gel, balancing cleansing power and moisturizing, avoiding skin tightness after washing, and improving shower comfort.
III. Compliance
1. Storage conditions
IPP and PTIS: They should be stored at room temperature, away from light, and sealed to prevent deterioration caused by exposure to light and air;
2EHS: Store in a cool and dry place at a temperature below 30 ℃ to avoid high temperatures affecting fluidity and stability. The packaging of the three products is 175kg/drum (IPP), 20kg/drum (PTIS), and 180kg/drum (2EHS).
2. Compliance
All three products comply with the International Classification of Cosmetic Ingredients (INCI) and are clearly labeled with the INCI name to facilitate product labeling compliance; And in accordance with the EU Cosmetic Regulation (EC No 1223/2009) and China's Cosmetic Safety Technical Specification, all products pass inspection before leaving the factory, and the latest version of COA is provided for each batch to ensure the safety and usability of raw materials. In the lotion system, NSOAF ™ The series is used in conjunction with
Ammonium acrylate copolymer to enhance emulsion stability and tactile balance, allowing the formula to maintain a uniform texture even under high temperatures and long-term storage.
