Dry-Flo® TS

Broad compatibility

• Compatibility with other ingredients offers formulation flexibility.
• Can be used with a wide range of other raw materials such as oils, emollients, silicones, UV filters, vitamins, botanical extracts, alpha and beta hydroxy acids, dihydroxyacetone, fragrances and dyes.

Tapioca starch

• Aluminum-free modified natural polymer.
• Biodegradable, based on non-genetically modified starch.
• Low protein content for sensitive skin and reduced allergy concerns.
• Free-flowing. Soft, powdery feel.
• Non-whitening on the skin.
• Talc replacement.
• Easily dispersed in cold water.
• Cost effective additive for a variety of skin care products.
• Improves aesthetics of a broad spectrum of formulations.

Oil-adsorber

Mitigates greasiness of lotions, creams, and ointments

• Processing requirements

1. For use in the powder form, Dry-Flo TS/TS Pure starches can be handled like any other natural starches.
2. For use in emulsion and hydroalcoholic systems, the starches should be added as a powder directly to the emulsion with proper mixing.
3. Care must be taken to incorporate the starch at 45°C or below when used in aqueous systems.
4. If temperatures above 45°C are encountered, the starch granule may begin to swell, reducing its effectiveness as an aesthetic enhancer and could potentially increase the formulation viscosity.
5. Dry-Flo TS/TS Pure starches may also be slurried in glycols or glycerin and incorporated into the formula with proper mixing at temperatures below 45°C.
6. While the biopolymer is tolerant to shear, it should not be extensively homogenized due to potential degradation of the starch.

• Compatibility

1. Dry-Flo TS/TS Pure starches are compatible with a wide range of commonly used cosmetic raw materials, including anionic, non-ionic, and cationic ingredients.
2. In addition, these polymers can be used with skin care actives such as sunscreens (organic and inorganic).
3. Dry-Flo TS/TS Pure starches can also be used in combination with other thickeners and emulsifiers.

• First, since an aluminum salt is not used in the production of Dry-Flo TS/TS Pure starches, these products are aluminumfree.
• Second, Dry-Flo TS/TS Pure starches are modified with polymethylsilsesquioxane, which imparts a velvety and soft after-feel to the skin.
• Due to their desirable feel properties, Dry-Flo TS/TS Pure starches can be utilized to cost effectively improve aesthetics in a variety of cosmetic products.
• Useful as effective talc replacements, Dry-Flo TS/TS Pure starches are natural polymers which can adsorb oil and do not produce undesirable whitening on the skin.
• Perhaps the most distinctive property of these unique products is its ability to impart a pleasant light, dry, and silky after-feel to finished formulations.
• Dry-Flo TS/TS Pure starches have the ability to mitigate greasiness – even in formulations containing high levels of oil.

Friction

• Friction testing is a measurement of surface friction, i.e. the frictional force required to pull a material sample, at a specified speed, for a specified distance over a horizontal surface.
• In frictional force testing (COF testing), the sample is normally wrapped around a metal block of specific dimensions and mass - called a ‘sled’, and another sample of the material is attached to a horizontal table.
• The less friction the product displays, the more slippery and smoother it feels.
• The coefficient of friction (COF) results for Dry-Flo TS/TS Pure starches compared to other commercially available aesthetic enhancers are displayed in the figure below.

Coefficient of friction results for various aesthetic enhancers

Dry-Flo TS/TS Pure starches provides less friction (COF), which translates to a smoother feel on skin, compared to other aesthetic enhancers

Oil-adsorption

• The oil adsorption of a powder is defined as the number of grams of synthetic sebum oil absorbed by 0.1-1.0 grams of the powder.
• Thus this test is a measure of the ability of a powder to hold onto oil.
• Dry-Flo TS/TS Pure starches were compared for oil adsorbency vs. other starches, with the results displayed in the figure below.

Oil adsorption of various starch technologies

• Dry-Flo TS/TS Pure starches are readily biodegradable and not genetically modified.
• In addition, Dry-Flo TS/TS Pure starches contain very low protein content which makes them suitable for sensitive skin or other products where allergens are of concern.
• The suitability of the final formulations should be confirmed in all respect by appropriate evaluation.

• Dry-Flo TS/TS Pure starches are a finely divided organic particulate.
• When handling, avoid generation of dust.
• Use in a well ventilated area.
• Use of a dust mask is recommended.
• Avoid contact of the Dry-Flo TS/TS Pure starches powder or dust with heat, sparks, or open flame.
• Dry-Flo TS/TS Pure starches should be stored in a cool, dry location away from heat, sparks, or fire. Good industrial hygiene practices should be followed when working with this starch.
