IOTA 99336 PEG-10 polydimethylsiloxane helps develop water-in-silicone oil formula, suitable for various scenarios of sunscreen makeup products

1. Core performance analysis of the product, balancing emulsifying ability and excellent skin feel
IOTA 99336 is PEG-10 polydimethylsiloxane, a polyether-modified organic silicone emulsifier. It has excellent W/Si and W/O emulsifying capabilities and can achieve low-temperature emulsification operations. After application, the finished formula presents a smooth and refreshing sensation without a heavy and sticky feeling. It is commonly used as an emulsifying raw material in skincare, makeup, and sunscreen formulations. The product appearance is colorless to slightly yellow transparent to semi-transparent liquid, with stable physicochemical indicators and good compatibility with various oils and powder raw materials, suitable for high-humidity formula systems.


2. Expanded application scenarios, covering various personal care products
This raw material has a wide range of applications and can be used in skincare creams, foundation liquids, BB creams, sunscreen lotions, etc. As the main emulsifier, the recommended addition amount is 1% to 4%; as a co-emulsifier, the addition amount is only 0.1% to 1.5%. During formula preparation, no high-temperature homogenization is required, and simple stirring can form the emulsion. Adding a small amount of electrolytes can further improve the long-term storage stability of the emulsion and reduce the risk of formula stratification.


3. Customer frequently asked questions, answering practical formulation questions
Q: Can IOTA 99336 only be used in silicone oil-in-water systems?
A: Not limited to silicone oil-in-water, it also has excellent water-in-oil emulsifying ability. Both oil-in-water and silicone oil-in-water systems can be developed. There is a larger selection of formula choices.

Q: When using this raw material for sunscreen formulations, will it affect the dispersion of sunscreen agents?
