ShampooConditionersHair treatments
Silica can be used in a wide range of cosmetic products such as shampoos and rinse-off conditioners, hair sprays and treatments, skin creams and lotions, antiperspirants and deodorants, shaving lotions and sun care products.
DESCRIPTION
Hair silica (PEG-12 dimethicone): water-soluble silicone that adds softness and shine. Used in shampoo, conditioners and hair treatments.
Silica
Silica is a silicone copolymer soluble in water, alcohol and hydroalcoholic systems.
Characteristics:
It works as a surface-tension reducer, foam former, wetting agent and emulsifier for O/W emulsions.
Benefits:
- Excellent conditioning effect on hair, with a soft, non-greasy feel and no buildup. Hair is easy to manage, with volume. It also helps build foam.
- In skin creams and lotions, it can be used as a wetting agent for a light, silky sensory feel, and also acts as an anti-tack agent and emollient booster. Works as the primary emulsifier in stable O/W emulsions.
Practical formulation guide
Usage level: Guideline range: 0.5–5 % in creams, lotions and conditioners; up to 20–80 % in hair serums, primers and anhydrous products.
Directions:: We recommend 0.1–5 % silica in rinse-off shampoos and conditioners for a conditioning effect. For leave-on treatments, the optimal level is 0.1–2 %. For skin-conditioning products, we recommend 0.1–3 % silica. If you want to use Silica as the primary emulsifier for silky O/W emulsions, we recommend 4 % Silica in the water phase. Compatible with hydroalcoholic systems; incompatible with waxes, mineral oils and medium-viscosity dimethicones.
Typical data::
- They provide slip, shine and a silky feel without greasiness; combine with light esters to adjust skin feel.
- Not all silicones are soluble in vegetable oils: run a miscibility test before formulating.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Compatible with esters, mineral oils and most emulsifiers; PEG-dimethicones are compatible with aqueous systems and surfactants.
Storage: Store in the original container, tightly closed, in a cool, dry place away from direct light. Close immediately after each use to prevent moisture and contamination.
Precautions: Low-hazard product. Spills are very slippery. Avoid contact with eyes.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
